Autonomous and Continuous Mode
- The station determines its own transmission schedule, based on data link traffic history and knowledge of future actions by other stations. It also means that the station, automatically resolves contention between itself, and other stations.
- The station uses a transmission schedule, assigned by a controlling station.
- Interrogation followed by response.
Either Autonomous/Continuous OR Assigned Mode.
Polled Mode operates in parallel. Transmission schedule may, or may not be assigned.
Operating modes describe the position reporting process in the AIS.
