    Appendix E - AIS connection for MX512 only Introduction AIS is a shipborne broadcast transponder system in which ships continually transmit their ID, position, course, speed and other data to all other nearby ships and shoreside authorities on a common VHF radio channel. The concept is derived from the pioneering work of a Swedish inventor named Håkan Lans, who developed in the mid 1980s an ingenious technique for spontaneous, masterless communication, which permits a large number of transmitters to send data...

  • Page 160: Coastal Surveillance

    Coastal Surveillance In coastal waters, shoreside authorities may establish automated AIS stations to monitor the movement of vessels through the area. These stations may simply monitor AIS transmissions from passing ships, or may actively poll vessels via the AIS channels, requesting data such as identification, destination, ETA, type of cargo and other information.
