The AIS can be supplied with the following sensor data, corre-
sponding to IEC 61162-1/2 (bold type = required default telegrams):
-
Reference datum (
DTM
, NACOS xx-4, RADARPILOT 1000 only)
-
Positioning system (GNS,
GLL
, RMC)
-
Speed over ground (
VBW
,
VTG
, RMC)
-
Course over ground (RMC,
VTG
)
-
Heading (
HDT
)
-
RAIM indicator (GBS)
-
Rate of turn (
ROT
)

Output of the messages corresponding to (IEC 61108-1) from internal position
sensors, RS422, IEC61192-1 (4800 Baud):
DTM (datum reference); GGA (GPS fix data); GNS (GNSS fix data); GLL (geographic
position, latitude/longitude); RMC (recommended minimum specific GNSS data); VTG

Connection to a long range communication system. Requests by the messages LRI and
LRF are answered with LR1, LR2 and/or LR3.
The wires can be connected
to the connectors directly by
means of screw terminals.

8
Output - / TxD -
Output of VDM messages (received by VHF) and VDO messages (sent by VHF).
The static ship’s data such as ship’s name, callsign and destination are input by means
of the VSD and SSD messages. See IEC 61993-2 for valid messages.
This port is connected to the SAM Electronics system, for example.
Additionally, the sensor data (VDO message) are sent with a repetition rate of 1 Hz.
