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. It’s 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 suitable VHF-AIS antenna splitter.
The AIT2500 has the option of an AIS SART alarm which is great for use with personal AIS MOB devices.
Specifications:
Class B+ 5W transponder with GPS/GLONASS positioning
Multiple NMEA 0183 in/out and multiplex capability
NMEA 2000 connectivity
USB connectivity for PC/MAC
Remote TX silence switch option
Supplied with GPS antenna
Options include VHF-AIS antenna splitter, wireless interface (WLN10SM) and AIS SART Alarm (AIS Lifeguard)
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.
