Navico V3100 SOTD

The V3100 Class B AIS incorporates the same SOTDMA technology found in Class A solutions. This self-organising transmission technology allows the system to negotiate a regular transmission timeslot with other AIS units in range, facilitating more frequent and reliable position updates in high-traffic areas. The V3100 transmits updates, based on vessel speed, up to once every five seconds; this provides up to six times the reporting frequency of standard Class B AIS.
