The V3100 Class B AIS is designed to meet the needs of light commercial vessels and workboats operating in high-traffic areas. SOTDMA technology and increased transmission power enhance transmission frequency, reliability, and range compared to standard Class B AIS. This ‘black-box’ solution integrates with Simrad displays, and features industry-standard connectivity.

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.
The V3100 features a maximum transmission power of 5 Watts, 2.5 times the transmission power of standard Class B AIS solutions. This allows vessels equipped with the V3100 to be detected over AIS at a greater range, and provides more reliable transmission to satellite-based AIS receivers.
This ‘black box’ AIS solution is designed to work with Simrad multifunction displays, and other NMEA 2000® or NMEA 0183® connected marine electronics. Output to a standard PC is also supported via USB connectivity. The V3100 is contained in a compact IP67 water-resistant housing, and includes a built-in SD card slot for standalone AIS data logging.
