FOREWORD
How AIS Works
1. What is AIS
AIS stands for Automatic Identification System. AIS increases
navigational safety and collision avoidance by transmitting vessel
identification, helping to reduce the difficulty of identifying ships when
not in sight (e.g. at night, in radar blind arcs or shadows or at distance)
by broadcasting navigational intentions to other vessels by providing ID,
position, course, speed and other ship data with all other nearby ships and
land based stations.
According to IALA regulations, AIS is defined as follows:
AIS is a broadcast Transponder system, operating in the VHF maritime
mobile band. It is capable of sending ship information such as
identification, position course, speed and more, to other ships and to shore.
It can handle multiple reports at rapid update rates and uses Carrier Sense
Time Division Multiple Access (CSTDMA) technology to meet these high
broadcast rates and ensure reliable and robust ship to ship operation.
The IMO defines the performance standards as follows:
Ship to ship working, ship to shore working, including long range
application, automatic and continuous operation, provision of information
messaging via PC and utilization of maritime VHF channels.
2. What AIS classes do exist?
There are two classes of AIS units fitted to vessels, Class A and Class B.
In addition AIS base stations may be employed by the Coastguard, port
authorities and other authorized bodies. AIS units acting as Aids to
Navigation (A to N) can also be fitted to fixed and floating navigation
markers such as channel markers and buoys.
1

2.1 Class A
Class A units are a mandatory fit under the safety of life at sea (SOLAS)
convention to vessels above 300 gross tons or which carry more than 11
passengers in International waters. Many other commercial vessels and
some leisure craft also may be fitted Class A units.
The Class A operation consists of three different types of messages:
Dynamic information:
position of the ship (derived from GPS)
time, when the position was measured in UTC
course over ground (COG)
speed over ground (SOG)
heading (HOG)
ship status
rotational speed/turn rate
Static information:
MMSI number
call sign and name of the vessel
length and width of the vessel
IMO-number of the vessel, if existent
type of vehicle
position of the GPS sensor onboard
Journey-related information:
draught of the vessel
type of cargo
port of destination and estimated time of arrival (ETA)
route plan, optional compulsory way, depending on the vessels
movement.
2

The following table shows the mandatory repetition rate of class A
transmissions linked to the ship`s movement:
anchored vessels 3 minutes
vessels at 0 14 kn 10 seconds
vessels at 0 14 kn, fast maneuver 3.3 seconds
vessels at 14 23 kn 6 seconds
vessels at 14 23 kn, fast maneuver 2 seconds
vessels at > 23kn 2 seconds
vessels at > 23 kn, fast maneuver 2 seconds
Static information as well as information belonging to the journey is
dispersed every 6 minutes.
The reporting intervals correspond to both radio channels (161.975 MHz,
162.025 MHz) together.
2.2 Class B
C
lass B: EN62287, 2005:
class B operation is described in the standard EN62287, published in
2005. This document is obligatory for class B.
Class B units are designed for fitting in vessels which do not fall into
the mandatory Class A fit category.
The KS-200A is a Class B AIS unit
Reporting intervals are:
Dynamic ship data:
boats at < 2 kn: 3 minutes
boats at > 2 kn: 30 seconds
Static ship data (similar to class A): 6 minutes
These intervals are the standard operation modes. Competent authorities,
like base stations, can have influence on the reporting intervals (as they
do with class A as well). Interval timing can be reduced down to 5
seconds in exceptional cases. There is no automatism to change the
30sec/3min dynamic intervals by the ship itself.

4. Installation of GPS Antenna
The GPS antenna is mounted in an elevated position and free of shadow
effect from the ship's superstructure.
The GPS antenna has a free view through 360 degrees with a vertical
angle of 5 to 90 degrees above the horizon.
As the received GPS signal is very sensitive to noise and interference
generated by other onboard transmitters, ensure that the GNSS antenna
is placed as far away as possible from radar, Inmarsat and Iridium
transmitters and ensure the GPS antenna is free from direct view of the
radar and the Inmarsat beam.
It is also important that the MF/HF and other VHF transmitter antennas
are kept as far away as possible from the GNSS antenna. It is good
practice never to install a GNSS antenna within a radius of 2 meters from
these antennas.

5. Installation of VHF Antenna
For the VHF antenna there is a VHF female bulkhead connector used, that
mounts to the back of the case.
The VHF antenna employed for AIS use:
Must be a dedicated antenna, i.e. not shared with any other VHF
transmitter/receiver.
Must be suitable for marine shipboard applications (index of protection,
ruggedness, means of mounting, etc.).
Should be omni-directional and vertically polarized with unity gain (0dB)
with a bandwidth sufficient to maintain VSWR <1.5 over the frequency
range 156-163 MHz. As a minimum the 3dB bandwidth must cover the
two AIS channels and the DSC Channel.
Should be mounted with at least a two meter vertical separation distance
from any other VHF antenna used for speech or DCS communication.

6. Connect to other navigational equipment
You can use the delivered cable (KS2-data1) to connect the AIS to other
navigational equipments such as plotter, radar etc.
Please connect the DB9 connector of KS2-data1 cable to the DB9 socket
of KS200A/B. Connect the other end of KS2-data1 cable to external
navigational equipments according to the following diagram :
