AIT2500 - Class B+ 5W AIS Transponder with GPS Antenna

The AIT2500 is a full function Class B+ SOTDMA AIS transponder with NMEA 0183, NMEA 2000 and USB data outputs. It is supplied with a GPS antenna.

Digital Yacht has recently unveiled a new series of Class B+ AIS transponders. This new standard, Class B+, utilizes SOTDMA format transmissions, providing a 5W power output (2.5 times more powerful than a regular Class B), a guaranteed time slot for transmission in busy traffic areas, and faster update rates depending on the vessel's speed. This makes it an excellent choice for ocean sailors seeking optimal performance, as well as for future-proof satellite tracking applications, fast power boats, and smaller non-mandated commercial vessels. Importantly, it remains compatible with existing Class B and Class A systems.

The AIT2500 is a comprehensive SOTDMA AIS transponder that offers NMEA 0183, NMEA 2000, and USB data outputs. It comes with a GPS antenna and requires connection to a VHF antenna or a suitable VHF-AIS antenna splitter.

Additionally, the AIT2500 offers the option of an AIS SART alarm, making it an excellent choice for use with personal AIS MOB devices.

Note On Sotdma Technology
Class B+ is a new generation of AIS functionality based on SOTDMA (self organised TMDA) messaging rather than the simpler CSTDMA (carrier sense TDMA). It guarantees your AIS transmission will get a time slot, even in areas of very high traffic density. It also specifies a 5W transmission power (compared with 2W for Class B) and a transmission rate that increases as the vessel moves faster. The transmission rate is fixed at every 30 seconds when the vessel is moving with regular Class B protocol. It is therefore ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications, fast power boats and smaller non-mandated commercial vessels.
