GENERAL WARNINGS All marine Automatic Identification System (AIS) units utilize a satellite based system such as the Global Positioning Satellite (GPS) network or the Global Navigation Satellite System (GLONASS) network to determine their position. The accuracy of these networks is variable and is affected by factors such as the antenna positioning, the number of satellites that are available to determine a position and how long satellite information has been received for. It is desirable wherever possible

to verify both your vessel’s AIS derived position data and other vessels’ AIS derived position data with visual or radar

based observations.

In most countries the operation of an AIS unit is included under the vessel’s marine VHF license provisions. The vessel onto which the AIS unit is to be installed must therefore possess a valid VHF radiotelephone license which lists the AIS system and the vessel Call Sign and MMSI number. Please contact the relevant authority in your country for more information.

1 General Introduction

1.1 Description of AIS

AIS stands for: “Automatic Identification System”

What is AIS?

According to IALA regulations, AIS is defined as follows: AIS is a broadcast transponder system, operating in the VHF maritime mobile Band (161,975 and 162,025 MHz). It is capable of sending ship information such as identification, position, course, speed and more to other ships and to shore stations. It can handle multiple reports at rapid update rates and uses Self-Organizing Time Division Multiple Access (SOTDMA) technology to meet these high broadcast rates and ensure reliable and robust operation.

The Modules of an AIS are:

 DGPS / GPS receiver  VHF Radio  Antenna  Computer (CPU)  Power Supply

Appropriate application software connects the individual modules.

In which modes do AIS operate?

AIS devices are required to function flawlessly in a variety of modes. The relevant regulations require that the system shall be capable of

 An "autonomous and continuous" mode for operation in all areas. This mode shall be capable of being

 An "assigned" mode for operation in an area subject to a competent authority responsible for traffic

 A "polling or controlled" mode, where the data transfer occurs in response to interrogation from a ship

Types of AIS:

 Class A Transponder – This type of transponder is used on open sea waters and is mandatory for ships

 Class B Transponder – Used on smaller vessels and pleasure crafts. It transmits with less power than

 Base Station – Fixed shore station that is typically connected to an AIS network to collect information

 Repeater Stations – Used to extend the coverage range by repeating incoming messages. Can be

 SAR (Search and Rescue) Transponder – Used on airplanes and helicopters in search and rescue

 AtoN (Aids to Navigation) – A transceiver that is fitted on buoys and lighthouses in order to send

 Inland AIS – A European standardized extension to Class A systems for use on inland water ways. An

AIS in an Operational Environment

This illustration depicts a typical AIS System, where two or more AIS equipped vessels (and shore based systems) are automatically communicating with each other.

Figure 1 – AIS System

Both vessels in the above illustration are equipped with a NAUTICAST A2 (or any other certified AIS-

Transponder). Due to “Time – Synchronization” they use the same organization of free and allocated windows (Slots) in the shared VHF Data Link (this method is called “Self Organized Time Division Multiple Access”) to send and receive messages.

On the next page, a typical NAUTICAST A2 installation in a common environment is shown. The NAUTICAST A2 is connected to the vessel’s emergency power supply, and in connection with the VHF, and GPSAntennas, the minimal requirements for transponder operation are fulfilled. By means of standardized messages the involved AIS systems exchange certain static data and dynamic information, such as the location and the course of the other ships in the area.

1.2 AIS Networks

The illustration below shows a full AIS covered area (including applications and shore infrastructure).

Figure 2 – AIS Network

1.3 Inland AIS

The AIS Inland Standard is an European extension to class A devices for use on inland waterways. AIS Inland transponders support additional messages for communication with Bridges, Ports and locks. Blue Sign or dangerous cargo messages can also be transmitted.

Note: The NAUTICAST A2 AIS can operate in both modes, standard (SOLAS) class A and Inland, depending the user’s needs.

2 System Overview

2.1 Product Description

The NAUTICAST A2 System consists of a transceiver radio unit, a GPS receiver, a controller unit and a colour LCD with a numerical keypad. The radio has three receivers, two tuneable TDMA receivers and one DSC receiver. The transmitter alternates its transmissions between the two operating TDMA. The controller unit creates and schedules data packets (containing dynamic, static and voyage related data) for transmission based on the IMO performance standard for AIS. The NAUTICAST A2 shall be connected to the ship’s sensors as required by the installation guidelines published by IALA. The NAUTICAST A2 can interface external navigation and presentation systems that support required IEC 61162-1 sentences. Refer to chapter 8 for more information. The NAUTICAST A2 is prepared for connection to Long Range systems like Inmarsat C. The colour LCD and numerical keypad provides a graphical user-friendly interface to the system. It is possible to plot the location of other vessels, aids to navigation and search and rescue vessels.

Interference to the Ship’s VHF Radiotelephone

The AIS ship borne equipment, like any other ship borne transceiver operating in the VHF maritime band, may

cause interference to a ship’s VHF radiotelephone. Because AIS is a digital system, this interference may occur as a periodic (e.g. every 20 seconds) soft clicking sound on the ship’s radiotelephone. This affect may become

more noticeable if the VHF radiotelephone antenna is located close to the AIS VHF antenna, and when the radiotelephone is operating on channels near the AIS operating channels (e.g. channels 27, 28 and 86). Attention should be paid to the location and installation of the various antennas, in order to support the antenna characteristics in the best possible way.

3.4.1 VHF Antenna Location Location of the mandatory AIS VHF-antenna should be carefully considered. Digital communication is more sensitive than analogue/voice communication to interference created by reflections caused by obstructions such as masts and booms. It may be necessary to relocate the VHF radiotelephone antenna to minimize interference effects.

To minimize interference effects, the following guidelines apply:

 The AIS VHF antenna should have omnidirectional vertical polarization.  The AIS VHF antenna should be placed in an elevated position, as free standing as possible, with a

minimum of 2 meters in horizontal direction from constructions made of conductive materials. The antenna should not be installed close to any large vertical obstruction. The AIS VHF antenna should have a visible sky of 360°.

 The AIS VHF antenna should be installed at least 3 meters away from interfering high-power energy

sources such as radar and other transmitting radio antennas, and out of the way of the transmitting beam.

 There should not be more than one antenna on each level. The AIS VHF antenna should be mounted

directly above or below the ship’s primary VHF radiotelephone antenna, with no horizontal separation and

a minimum of 2 meters vertical separation. If it is located on the same level as other antennas, the distance apart should measure at least 10 meters.

3.4.2 VHF Cabling The cable should be kept as short as possible to minimize attenuation of the signal. Double shielded coaxial cable equal or better than RG214 is recommended to minimize the effects from electromagnetic interference from high power lines, radar or other radio transmitter cables. The table below gives recommendation on cables that can be used for the VHF-antenna connections, the cables used should always be of marine approved type. The cable attenuation shall be kept as low as possible; a 3 dB loss is the same as cutting the signal strength in half.

Example: A cable of 40 meter RG 214 has a cable attenuation of 2.8 dB.

All outdoor connectors on the coaxial cables should be fitted with preventive isolation, such as shrink-stocking with silicone to protect the antenna cable against water penetration. Coaxial cables should be installed in

separate signal cable channels/tubes, and at least 10 cm away from any power supply cables. Crossing of cables should take place at right angles (90°). Coaxial cables should not be exposed to sharp bends, which may lead to changes to the characteristic impedance of the cable. The minimum bend radius should be 5 times the cables outside diameter.

Grounding

Coaxial down-leads must be used for all receiving antennas, and the coaxial screen should be connected to the ground at one end.

3.5 Mount the NAUTICAST A2 GPS Antenna

The NAUTICAST A2 shall be connected to a GPS antenna type Procom GPS-4 (1001022), Nauticast Standard GPS antenna (3001002) or to a combined GPS/VHF antenna AC Marine VHF/GPS-2 (1001027). 5V DC is supplied through the antenna lead for the antenna preamplifier. Please note the Compass Safe Distances in section 6.3 “Transponder Environment”. If the combined AC Marine GPS/VHF antenna is used the diplexer unit shall be installed in an indoor environment. Attention should be paid to the location and installation of the different antennas on the ship in order to obtain the best possible efficiency. How and where the GPS antenna and cable is installed will greatly affect its sensing efficiency.

3.5.1 GPS Antenna Location The GNSS antenna must be installed where it has a clear view of the sky, so that it accesses the horizon freely through 360°, with a vertical observation of 5 to 90 degrees above the horizon. Small diameter obstructions, such as masts and booms, do not seriously impair signal reception, but such objects must not eclipse more than a few degrees of any given bearing. The antenna must be located at least three meters away from, and out of the transmitting beam of highpower transmitters (S-Band Radar and/or Inmarsat systems). This includes the ship’s own AIS VHF antenna, if it is designed and installed separately. If a DGNSS system is included or connected to the AIS system, the installation of the antenna should be undertaken in accordance with IEC 61108-4, Edition 1.

3.5.2 GPS Cabling The gain of the GPS antenna built-in pre-amplifier shall match the cable attenuation. The resulting installation gain (pre-amplifier gain minus cable attenuation) shall be within 0 to 26 dB. A minimum value of 10 dB is recommended for optimum performance. A double shielded coaxial cable is recommended. The coaxial cable should be routed directly between the GPS antenna and the NAUTICAST A2 GPS connector in order to reduce electromagnetic interference effects. The cable should not be installed close to high-power lines, such as radar or radio transmitter lines or the AIS VHF antenna cable. A separation of 1 meter or more is recommended to avoid interference due to RF-coupling. Crossing of antenna cables should be done at 90 degrees to minimise magnetic field coupling. The table below gives recommendation on cables that can be used for the Transponder GPS-antenna

connections, the cables used should always be of marine approved type. Due to the high frequency it’s

important that the attenuation in the cable is low for the specific frequency (1.5 GHz).

For optimum performance approximately +10dB gain should be available when the cable attenuation has been subtracted from the GPS-antenna preamplifier gain. The net gain shall not exceed +26dB.

Coaxial cables (marine approved type) should be installed in separate signal cable channels/tubes and at least 10 cm away from power supply cables. Crossing of cables should be done at right angles (90°). Coaxial cables should not be exposed to sharp bends, which may lead to a change of the characteristic impedance of the cable. The minimum bending radius should be 5 times the cable's diameter. All outdoor installed connectors should be weather proofed, e.g. with shrink tubing, watertight seal tape or butyl rubber tape and plastic tape sealing, to protect against water penetration into the antenna cable. Secure the cable properly near the cable ends.

Grounding Coaxial down-leads must be used. The coaxial shielding screen should be connected to ground at one end.

3.6 Electrical Installation

The protocol of the serial port interfaces is compliant to IEC 61162-1Ed.4 (2010-11). All serial ports in the NAUTICAST A2 have the same capabilities with one exception, any Long Range equipment must be connected to the Long Range port. The primary external position sensor should be connected to the Sensor 1 port since this port has the highest priority. The serial ports in the NAUTICAST A2 can also receive differential corrections in RTCM format for correction of the internal GPS receiver. The ports in the NAUTICAST A2 have different default baud rates but they can all be configured to any baud rate of 4800, 9600, 38400, 57600 or 115200 bps. The priority levels for input of sensor data on the different ports are listed below:

Table 5 Port Priorities and Default Baud Rates

NOTE 1: This means that if valid position data from external position sources are input on e.g. both Sensor 1 and ECDIS port, the position data from Sensor 1 will be used. NOTE 2: Output will be limited if baud rate is below 38400 bps. VDM and VDO messages will not be output.

If the same data is provided using different NMEA sentences on the same port, the priority depends on the

3.6.7 External Switch The Power Cable enables connection of an external switch to the NAUTICAST A2. This switch can be used as a Silent switch or, if configured as an Inland AIS system, as a Blue sign switch.’

3.6.7.1 Blue Sign installation (Inland Mode only)

If the blue sign switch should be used, the parameter “External Switch” must be configured to “Blue Sign” in

Misc. Interface view accessed from

Main Menu  Config  Interfaces  Miscellaneous

. The status of the blue sign can be controlled by input on the brown and orange wires of the Power Cable. The status of the Blue Sign will be read by the NAUTICAST A2 and output on the VHF data link when operating in “Inland Mode” (see section 4.4.16 for more details). Connect the blue sign switch to pin 3 (brown wire) and pin 4 (orange wire) of the Power Cable together with an external parallel resistor. When the switch is open, blue sign will be off. When the switch is closed, blue sign will be on. The external resistor value depends on the power supply voltage the NAUTICAST A2 is using:

 12V: 2.2kΩ resistor, 10% tolerance, at least 1/8W power rating  24V: 10kΩ resistor, 10% tolerance, at least 1/8W power rating

Figure 5 – Blue Sign Switch

3.6.7.2 Silent switch installation It is possible to connect a silent switch to the NAUTICAST A2 to quickly turn off transmissions.

If a silent switch is to be used, the parameter “External Switch” must be configured to “Silent Switch” in Misc.

Interface view accessed from The silent switch should be connected in the same way as the blue sign switch. However, the external resistor may be omitted for the silent switch. When the circuit is closed (brown and orange wires connected with each other), the NAUTICAST A2 will transmit as normal. When the circuit is open, the NAUTICAST A2 will be completely silent.

3.6.8 Alarm Relay It is required that the AIS alarm output (relay) is connected to an audible alarm device or the ship’s alarm system, if available.

Alternatively, the ship’s BIIT alarm system may use the alarm messages output on the AIS Presentation

Interface (PI) provided the alarm system is AIS compatible. The AIS Alarm Relay is either mounted directly on a board or on the wall. The alarm relay wires have the following colour codes in the 26-pole NAUTICAST A2 data interface cable:

Figure 6 shows the alarm relay and its dimensions and explains how to connect the alarm relay to the data cable and how to connect the load (Alarm Circuit) to the alarm relay. The operating voltage of the alarm relay is 3 to 60 VDC with a load current of 0.1 to 2 A (3A when using a heat sink).

Parameter Name

Description

Sensor Data Source

This parameter specifies which port the NAUTICAST A2 should use as its external sensor source. The default value of this

parameter is “Automatic” which means that the NAUTICAST

A2 will accept sensor information on any port and use the information on the port with highest priority. If Sensor Data Source is set to anything other than “Automatic”, the NAUTICAST A2 will only accept sensor information if it comes from the port specified by this parameter. The parameter reverts to “Automatic” after a reboot.

SART Test Mode

This parameter determines if SART Test targets should be displayed in Target List and Plot views of the NAUTICAST A2. It also controls if connected systems, for example ECDIS, will receive SART Test targets.

7 Troubleshooting

The Nauticast A2 is a very rugged and stable device, so that in the majority of cases erroneous configurations rather than real hardware defects are the cause of perceived malfunctioning.

7.1 Troubleshooting Prerequisites

A transponder operating environment may naturally affect and render complicated the search for the root cause of a system defect. It is always advisable to start by minimizing all possible interference sources in order to simplify the troubleshooting.

 Disconnect other NMEA equipment from the NAUTICAST A2 (ECDIS, RADAR, NAV, etc.)

 Switch off other emission sources (RADAR, SATCOM, VHF, etc.)

We encourage applying the latest software available for the NAUTICAST A2 if any problems are experienced. It may contain bug-fixes and other improvements solving already known issues. Check supplied software release notes to see what has been changed in the new software.

7.2 Troubleshooting with the Front Panel LED’s

It is very fast and effective to use the LED’s to verify the status of the NAUTICAST A2. This should always be

the first step in the troubleshooting.

7.2.1 STATUS LED (multi-colour)

 The STATUS LED is constantly lit green when the transponder is operating and no alarms are active.

 The STATUS LED is constantly lit red if there is one or more acknowledged active alarms in the

transponder, but no unacknowledged alarms. Refer to section 7.3 for interpretation of the alarms.

 The STATUS LED is flashing red if there is one or more unacknowledged alarms in the transponder.

Refer to section 7.3 for interpretation of the alarms.

If neither colours are lit, nor flashing, then check the power supply and make sure that:

 The voltage is correct and stable

 The polarity is correct and not switched

 The available current is sufficient for start up and transmission

 The external fuse is functional

 The power cable is undamaged

 The power connector is properly connected and secured

Also check so that the LED backlight is not completely turned off in the Visual Config view accessed from

MenuConfigDisplayVisual

7.2.2 Rx LED (yellow) The Rx LED is flashing yellow when the transponder is receiving a message from the VDL. This can be intermittently. If there is verified traffic on the VDL and the Rx LED still is dark, then check the alarm list for any active alarms. Refer to section 7.3 for interpretation of the alarms. Lack of reception may be an indication of a VHF antenna problem or connectivity issues. Check the installation for problems.

7.2.3 Tx LED (red) The Tx LED is flashing red when the transponder is transmitting a message to the VDL. The transmission interval is between 2 – 360 seconds. Refer to section 7.5. If the Tx LED is completely dark, then check so that the transmission is not switched off either through an active regional area or by the Tx Mode parameter. It is possible to check the status on each transceiver in the VHF Status view described in section 4.24. If the transmission is activated and there is still no red flashing, then check the alarm list for any active alarms. Refer to section 7.3 for interpretation of the alarms.

Main

7.3 Troubleshooting with Alarm Messages

The NAUTICAST A2 constantly monitors itself for failures, abnormal conditions and other important parameters. Some of the monitoring trigger alarms and those alarms are excellent aids in the troubleshooting process. An active alarm can have two states, unacknowledged or acknowledged. The state of an alarm will affect the STATUS LED. Refer to section 7.2.1.

Page 45 of 80 1001001-2EN A2 Product Manual 2_0

A new alarm (unacknowledged) will raise a pop-up window that needs to be acknowledged by the user. The active alarms can be found in the alarm view. Refer to section 4.18. All active alarms are outputted on all the serial interface ports every 30 seconds. The alarm status can for example be used in interfacing ECDIS systems or centralized alarm systems. The alarms can also be monitored or recorded for troubleshooting purposes by for example a terminal application.

The status of an alarm can be identified by two letters in the alarm sentence, “A” and “V”. The alarm

sentence is constructed as:

$AIALR,hhmmss.ss,xxx,A,A,c-c, where: hhmmss.ss = Time (UTC) of alarm condition change xxx = Unique alarm identifier A = Alarm condition (A = Active, V = Inactive) A = Alarm’s acknowledge state, A = acknowledged, V = unacknowledged c-c = Alarm’s description text

$AIALR,hhmmss.ss,xxx,V,A,c-c: Tx malfunction $AIALR,hhmmss.ss,xxx,V,V,c-c: Tx malfunction $AIALR,hhmmss.ss,xxx,A,A,c-c: Tx malfunction $AIALR,hhmmss.ss,xxx,A,V,c-c: Tx malfunction

: Alarm is Inactive : Alarm is Inactive

: Alarm is Active and Acknowledged : Alarm is Active and Unacknowledged

The alarms that can occur in the NAUTICAST A2 are listed below:

7.3.1 AIS: Tx Malfunction (ID 001) A Tx Malfunction alarm is generated if there is a malfunction in the radio transmitter hardware or if the antenna VSWR exceeds an allowed ratio. If the radio transmitter returns to normal operation or if VSWR returns to a value below the allowed threshold, the alarm is cleared. The Tx Malfunction alarm is also generated when the MMSI is configured to “0”, in which case the NAUTICAST A2 will not transmit.

7.3.2 AIS: Antenna VSWR Exceeds limit (ID 002) The VSWR (Voltage Standing Wave Ratio) of the antenna is checked for every transmission and if it exceeds a given ratio then a VSWR alarm is generated. If the VSWR goes below the allowed threshold, the alarm is cleared.

7.3.3 AIS: Rx Ch A Malfunction (ID 003)

7.3.4 AIS: Rx Ch B Malfunction (ID 004)

7.3.5 AIS: Rx Ch C Malfunction (ID 005)

The radio receivers are continuously monitored and if any part of the receivers’ hardware should malfunction,

an Rx Malfunction alarm is generated for that receiver. If the radio receiver returns to normal operation, the alarm is cleared.

7.3.6 AIS: General Failure (ID 006) This alarm is generated if the NAUTICAST A2 fails to initiate the radio or if a severe hardware failure has occurred. If this alarm occurs, contact your retailer.

7.3.7 AIS: UTC Sync Invalid (ID 007) This alarm is generated when the NAUTICAST A2 loses UTC direct synchronization (cannot synchronize from internal GPS receiver).

7.3.8 AIS: MKD connection lost (ID 008) This alarm is active if the communication between the control unit and the display unit in the NAUTICAST A2 does not work.

7.3.9 AIS: Internal/External GNSS position mismatch (ID 009) This alarm is generated if the difference between the internal and external GNSS position is more than 100 m for more than 15 minutes.

7.3.10 AIS: NavStatus incorrect (ID 010) This alarm is generated if the navigational status is incorrect. If e.g. the navigational status is set to “At Anchor” but the ship is moving faster than 3 knots, the NavStatus incorrect alarm will become active.

7.3.11 AIS: Heading sensor offset (ID 011) This alarm is active when SOG (Speed Over Ground) is greater than 5 kn and the difference between COG (Course Over Ground) and HDT (True Heading) is greater than 45˚ for 5 min.

7.3.12 AIS: Active AIS SART (ID 014) This alarm is generated when the NAUTICAST A2 has received an active AIS SART position report.

7.3.13 AIS: External EPFS Lost (ID 025) This alarm is generated if the position from the external Electronic Position Fixing System is invalid (i.e. no external GNSS). Due to the fallback arrangement for the positioning sensor this alarm can be inactive up to 30 seconds (during which the internal GNSS is used) before the alarm is activated.

7.3.14 AIS: No Sensor Position In Use (ID 026) This alarm is active if the NAUTICAST A2 does not have a valid position (latitude/longitude) from any sensor.

7.3.15 AIS: No Valid SOG Information (ID 029) / No Valid COG Information (ID 030) These alarms are active if the NAUTICAST A2 does not have a valid SOG (Speed Over Ground) or a valid COG (Course Over Ground) from any sensor. The SOG and COG is based on the speed log (if external GNSS is used and a valid heading is available) or the GNSS currently in use.

7.3.16 AIS: Heading Lost/Invalid (ID 032) This alarm is generated if either the heading information is lost/invalid (from external sensors) or if the heading is undefined.

7.3.17 AIS: No Valid ROT Information (ID 035) This alarm is active if ROT (Rate of Turn) is undefined or if no valid ROT information is available from external sensor or internal calculations.

7.3.18 IAIS: Ship Size mismatch (ID 060) This alarm is active when the inland parameters length and beam of ship does not match the antenna position parameters A, B, C and D.

7.3.19 AIS: Tx disabled externally (ID 072) This alarm is active when an external silent switch is used and the switch has disabled transmissions.

7.4 Troubleshooting via the Display

There is a lot of information and data accessible via the display that can be useful for troubleshooting, and that can help finding a presumed problem. The following items are just a few examples of what to look at.

7.4.1 Transmitted Own Ship Data View When the transponder transmits data on the VDL, it also simultaneously outputs this data on all the serial ports. This information is displayed in the Transmitted Own Ship Data view.

Figure 42 – Transmitted Own Ship Data

Page 47 of 80 1001001-2EN A2 Product Manual 2_0

7.4.2 Target List The target list is primarily useful when analyzing the receiving functionality. The propagation characteristics of VHF radio frequencies are close to line of sight. A harsh radio environment, reflections in cables, connectors or the antenna will shorten the effective range.

Figure 43 – Target List

7.4.3 Date and Time The date and time (UTC) in the upper right corner of the display is provided by the transponder. If the date and time are not correct, the transponders internal GPS does not have a position fix. This will also be indicated by the alarm “UTC sync invalid”. This problem is normally caused by a GPS-antenna failure or damaged antenna cables. This problem may also be caused by interference from radio equipment on-board.

7.4.4 View Raw Data The

View Raw Data

view can be used to see received data on the ports of the NAUTICAST A2. It is useful for

troubleshooting to make sure that connected sensors provide correct data to the NAUTICAST A2 unit. The

“View Port” parameter determines from which port the data displayed in the view are taken. It is possible to pause the view by pressing the “Freeze” button. All data that is received while the view is paused will not be

displayed in the view.

7.4.5 Status List The status list view is used to display status indications that are stored in the transponder. The indications are created when an important event has occurred in the transponder. Time of occurrence and status indication text are shown in the view. A list of all possible indications can be found in section 7.8 Indication Messages.

Figure 45 – Status List

7.5 Reporting Intervals for Class A Transponders

The different information types are valid for different time periods and therefore they need different update intervals. These update intervals are defined in the AIS standard (ITU-R M.1371) and should be applied by all transponders. There are however some exceptions from this, which can be found in the standard. Class B transponders have for example different intervals than the Class A transponder. All this needs to be taken in consideration while troubleshooting thus it affects the anticipated behaviour of a transponder.

Table 12 – Reporting Intervals

7.6 F.A.Q

7.6.1 I cannot see the vessel on the Internet AIS service Websites providing AIS services like e.g. www.marinetraffic.com does not cover all the seas of the world, but only specific coastal areas where AIS receivers have been installed and that upload the data to the websites. The vessel must be in reception range of these AIS receivers to show up on the Internet AIS service. If wrong information about your ship shows up on these websites (e.g. pictures or wrong position), this doesn’t mean your AIS is not working correctly. If the data is shown correctly on the AIS, the incorrect information is mostly due to false information delivered to these websites through other sources.

7.6.2 I can “see” the other vessel, but they do not “see” my vessel There are several reasons why this might happen. The first thing to check is if the NAUTICAST A2 is transmitting at all or if is transmitting in low power mode. In possible to check the status on all NAUTICAST A2 VHF transceivers. Make sure that correct channels and power mode are used. There might be a regional area set in the transponder that changes the operating mode of the NAUTICAST A2. Regional areas are listed in the The MMSI must also be configured in order for the NAUTICAST A2 to transmit. If the MMSI is zero, the NAUTICAST A2 will be silent.

Another possibility is that the other vessels’ transponder requires a shorter reception range in order to receive

the NAUTICAST A2 transmissions. In the bearing to other vessels.

7.6.3 The VHF range seems to be short As a general rule, the VHF range is equal to line of sight from the antenna position, which means that the higher the antenna is installed, the longer the range will be. It is also important to follow the guide lines for an antenna installation thoroughly. Section 3.4 describes how to best install the VHF antenna.

7.6.4 I can only receive a few GPS satellites The position of the GPS antenna is of high importance to optimize the GPS reception. Follow the guide lines of GPS antenna installation described in section 3.5. If the ship is close to a harbour or shore with high structures or travelling in an area with high terrain, the GPS reception might be lowered. The GPS antenna must be installed where it has a clear view of the sky. The objective is to see the horizon freely through 360 degrees with a vertical observation of 5 to 90 degrees above the horizon. The GPS antenna cable should also be as short as possible and with 50 Ω impedance. A very long antenna cable or faulty impedance can heavily reduce the GPS reception.

9 Interpretation of Output Sentences

9.1 Proprietary Output Sentences (PSTT)

In addition to the standardized IEC sentences, the NAUTICAST A2 is able to output the proprietary sentences listed below. All Nauticast Proprietary Sentences have talker ID “PSTT”.

9.1.1 $PSTT,10A – UTC Date and Time This sentence provides UTC Date and Time, i.e. NAUTICAST A2 system time (based on internal GNSS time). It is output approximately once every 10 seconds (± 1 s). $PSTT,10A,YYYYMMDD,HHMMSS

Example: $PSTT,10A,20121028,135230*<FCS><CR><LF> = Date October 28, 2012 = Time 13:52:30 UTC

9.1.2 $PSTT,10C – Data Link Status This sentence provides information about the traffic on the VHF data link. It is output approximately once every 60 seconds. Traffic load is calculated over the last frame (i.e. 60 seconds). Number of units is derived from the internal user list and is generally the number of received units within the last few minutes. $PSTT,10C,C,LLL,NNNN

9.1.3 $PSTT,146 – System Operational Mode Status This sentence reports the system operational mode. This sentence is output on change, periodically every minute and on request using PSTT,101. $PSTT,146,x,x,x*hh<CR><LF>

9.1.4 $PSTT,1F3 – Transponder Restart This sentence will be output when the transponder has restarted. $PSTT,1F3,R

The NAUTICAST A2 Transponder System runs on a Linux operating system which is licensed with GNU General Public License. The source code of the Linux kernel can be obtained by contacting Nauticast GmbH: Email: support@nauticast.com Copy of the GNU General Public License:

GNU GENERAL PUBLIC LICENSE

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA; Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.

The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow.

TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part

thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.

c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such

interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not

normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.

3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections

1 and 2 above on a medium customarily used for software interchange; or,

Version 2, June 1991

Preamble

GNU GENERAL PUBLIC LICENSE

Page 72 of 80 1001001-2EN A2 Product Manual 2_0

b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of

physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed

under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed

only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in

accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.

5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.

7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.

10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. <one line to give the program's name and a brief idea of what it does.>

NO WARRANTY

This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.

You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA Also add information on how to contact you by electronic and paper mail. If the program is interactive, make it output a short notice like this when it starts in an interactive mode: Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details. The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker.

<signature of Ty Coon>, 1 April 1989 Ty Coon, President of Vice This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful to permit linking proprietary applications with the library. If this is what you want to do, use the GNU Library General Public License instead of this License.
