AIT2500 Class B+ 5W SOTDMA AIS with GPS
Digital Yacht have a range of Class B+ AIS transponders. Class B+, a standard, utilizes SOTDMA format transmissions which offer a 5W power output (2.5x more powerful than a regular Class B), a guaranteed time slot for transmission in busy traffic areas and faster update rates depending upon the speed of the vessel. Its ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications, fast power boats and smaller non-mandated commercial vessels. It still inter-operates with existing Class B and Class A systems.
The AIT2500 is a full function SOTDMA AIS transponder with NMEA 0183, NMEA 2000 and USB data outputs. It is supplied with a GPS antenna and requires connection to a VHF antenna or suitableVHF-AIS antenna splitter.
The AIT2500 has the option of anAIS SART alarmwhich is great for use with personal AIS MOB devices.

Note On SOTDMA Technology
Class B+ is a 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. With regular Class B protocol, the transmission rate is fixed at every 30 seconds when the vessel is moving. It is ideal for ocean sailors requiring the best possible performance and future proof satellite tracking applications, fast power boats and smaller non-mandated commercial vessels.
The Digital Yacht AIT2500 Class B+ 5W SOTDMA AIS with GPS is a high-performance transponder designed for ocean-going vessels, fast powerboats, and smaller commercial ships requiring reliable AIS communication. This device utilizes advanced SOTDMA technology, which guarantees transmission in high-traffic areas by providing a dedicated time slot, ensuring your vessel remains visible and compliant with maritime safety standards.
Equipped with a powerful 5W transmission output, the AIT2500 offers significantly better range and signal strength compared to standard Class B units, making it ideal for vessels operating in open waters or busy shipping lanes. Its compatibility with NMEA 0183, NMEA 2000, and USB interfaces allows seamless integration with existing navigation systems, providing real-time data sharing and enhanced situational awareness. The included GPS antenna ensures accurate positioning, and the unit requires connection to a VHF or AIS VHF antenna splitter for optimal operation.
Additional features include an optional AIS SART alarm, which enhances safety by alerting crew to MOB incidents when used with personal AIS MOB devices. The device supports multiple data outputs, including multiplexed NMEA 0183 streams and USB connectivity for PC or Mac systems, enabling versatile data management. It also offers a remote transmission silence switch option, allowing operators to control AIS transmission as needed. Optional accessories include a VHF-AIS antenna splitter, wireless interface for remote management, and AIS SART alarm for increased safety.
Designed with future-proof technology, the AIT2500’s self-organized TDMA (SOTDMA) messaging ensures your vessel’s AIS transmission remains prioritized even in congested traffic environments. This generation of AIS offers higher transmission power and adaptive update rates that increase with vessel speed, ensuring rapid updates during high-speed maneuvers. The unit is a reliable choice for mariners seeking a robust, compliant, and advanced AIS transponder for safety, tracking, and navigation.
