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 (5W vs 2W for regular Class B) with enhanced transmission frequency, reliability, and range compared to standard Class B AIS. For a dedicated AIS display for this blackbox, use Simrad P2005, P3007 or IS42 Instruments, or a B&G Triton2 Instrument.

About AIS
The marine Automatic Identification System (AIS) is a location and vessel information reporting system. It allows vessels equipped with AIS to automatically and dynamically share and regularly update their position, speed, course and other information such as vessel identity with similarly equipped vessels. Position is derived from the Global Positioning System (GPS) and communication between vessels is by Very High Frequency (VHF) digital transmissions.
Increased Transmission Frequency and Reliability
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.
Increased Transmission Range
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.
Integrated ‘Black-Box’ Solution
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.
