Long Range Equipment Interface
The range of operation of standard AIS is limited to the range of VHF transmissions
which is around 30 miles. The Long Range mode is intended to allow the exchange
of ships position information from ship to a competent authority via a satellite inter-
face such as Inmarsat-C which is already onboard many ships. This port is intended
to interface with the Long Range equipment.
The Long Range reply can be set in either:
F
automatic mode (AUTO)
F
manual mode L-3 ProTec (MANUAL)
F
manual mode external application (EXT APPL).
The Long Range reply, when in AUTO mode, is made as soon as a request is re-
ceived on the Long Range communication port.
