10.1 AIS Operations
AIS (Automatic Identification System) is a system that continuously transmits the iden-
tification and position of your boat to AIS transponder equipped vessels within com-
municating range. All such vessels also receive data from other AIS transponder
equipped vessels and display their positions and other relevant information. The AIS
broadcasts this information over a VHF transceiver. Data include:
A maximum of 200 targets can be displayed, in the order in which they are received.
Connection to a Class A or B AIS transponder is required.
