Simrad AIS portfolio expanded with new SOTDMA Class-B solution

The new Simrad 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 output power provide improved transmission reliability and range, in a cost-effective package for vessels that require greater performance than standard Class B AIS but do not require a full Class A solution.

The V3100 Class B AIS incorporates the same SOTDMA technology found in Class A systems. This self-organising transmission technology allows the V3100 to negotiate a regular transmission timeslot with other AIS units in range, facilitating more frequent and reliable position updates in areas of high AIS activity such as crowded harbours and waterways. 

With a maximum transmission power of five watts – more than double the output power of standard Class B systems – the V3100 allows a vessel to be detected at 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.
