4.3 Long Range Interrogation
The AIS system can also be interrogated about own ship data by other systems than AIS via SatCom.
Because this interrogation can take place over longer distances than the VHF range, it is called "Long
Range Interrogation".
The interrogating station specifies which data are requested.
1)
The required reaction of the AIS system can be set by means of the Reply Mode, see Section 4.3.1.
Display of the Interrogation Received
The interrogation received last can be displayed in the dialog LONG RANGE INTERROGATION.
1)
Such interrogations can take place from shore stations, e.g. from shipping companies, traffic control centres or governmental organisations,
but not from the AIS systems that are usually found on board.
1. Press MENU.
2. In the menu, mark INTERROGAT by means of the ArrowUp/ArrowDown keys and press
ENTER. The interrogation received last is displayed.
Back: Press BACK twice.
