ATIS

Draft v5.0

27 Feb 2014

EU models only.

The Automatic Transmitter Identiﬁcation System (ATIS) is mandatory for vessels navigating on some European waterways. The system allows authorities to monitor and regulate VHF radio communications by identifying any vessel that makes a VHF transmission. Each vessel is required to have an ATIS-enabled radio on board and is allocated a unique ATIS Maritime Mobile Service Identity (MMSI).

Each time a radio operator ﬁnishes talking and releases the PTT key, the radio transmits a short digital message, which includes the ATIS MMSI. The receiving station can then look up details of the vessel, saving time in communication on the busy VHF channels.

Unlike DSC, the ATIS signal is transmitted on the same VHF channel as the voice transmission.

Before you can enable ATIS, you must enter the ATIS MMSI. See “Entering or checking your ATIS MMSI” on page 83.

Before you can enable ATIS, DSC must be turned oﬀ. See ”Enabling DSC functionality” on page 84. To enable ATIS, see “Enabling ATIS functionality” on page 83.

¼ Notes

• ATIS is disabled in US models.

• When ATIS is enabled, the ATIS icon appears on screen.

• In some European countries SCAN functionality is limited, and, if ATIS

is enabled, the 3CH SCAN and Dual scan modes will be disabled.

AIS procedures

The marine Automatic Identiﬁcation System (AIS) is a vessel location and information reporting system. It allows vessels to automatically share information such as position, speed, course and identity via a VHF radio link.

The received details of nearby vessels can be displayed on the handset screen together with closest point of approach times and distances. These details are also sent to the NMEA ports for display on a chart plotter if one is connected.

Closest point of approach (CPA) is the calculated closest distance between your vessel and a target vessel based on the current speed and course.

Time to closest point of approach (T/CPA) is the calculated time for a target vessel to arrive at the closest point of approach based on the current speed and course. If the radio detects that another vessel will come closer than the set CPA distance and within the set T/CPA time, the CPA alarm will sound. Both conditions must be met for the CPA alarm to sound.

For information on enabling AIS and setting the CPA time and distance criteria, see “AIS Setup” on page 88.

For general information about AIS, see “Appendix 9 - AIS information” on page 105.

For information on how to conﬁgure your chart plotter or software to make use of the RS90 AIS data, see the manual provided with that product.

¼ Notes

• Before the AIS functions can be used, the RS90 must receive its own

position from a GPS device, or manually entered data.

• The RS90 VHF radio includes an AIS receiver but does not transmit.

To access the AIS displays:

• Press [AIS]

• Repeat press [AIS] to switch between the three available displays:

MMSI list (list of nearby vessels) PPI display T/CPA list

From any of the above displays, you can select an MMSI to display details about the particular vessel.

Each vessel’s MMSI (or name, depending on AIS setup) will be displayed, together with its bearing and distance from your position.

PPI display

The Plan Position Indicator (PPI) shows the geographical location of AIS targets with respect to your position, which is represented in the centre of the circular display.

• Press [Scan] to zoom out.

Scales available are 1nm / 2 nm / 4 nm / 8 nm / 16 nm / 32 nm.

T/CPA screen

The Time and Closest Point of Approach (T/CPA) screen shows the closest point of approach settings together with a list of vessels that will approach within those criteria.

• CPA alert distance is set up in MENU → AIS SETUP → CPA. (See

“Setting up the CPA distance” on page 89.)

• T/CPA alert time is set up in MENU → AIS SETUP → TCPA. (See

“Setting up the T/CPA time” on page 90.)

The approaching AIS target’s details will be listed on the left of the screen.

Once the vessel is within alert distance (CPA) or time (T/CPA), it will be placed in the T/CPA list.

The alert sounds for every vessel within the criteria every time their AIS signal is received.

• In the example above, the criteria are: 5:00min and 8nM.

¼ Notes:

• The scale on the T/CPA Approach screen is automatically set to the

optimum for the selected target. You cannot zoom in or out on this screen.

• If the radio detects a T/CPA or CPA breach, the T/CPA Approach

screen will automatically popup with an alert tone. Press [X] to stop the alert; otherwise, the alert will sound again after 1 minute.
