Digital Yacht have introduced a new range of Class B+ AIS transponders. Class B+, a new standard, utilises 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 the option of an AIS SART alarm which is great for use with personal AIS MOB devices.
The AIT2500 will be available in January 2019.
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. 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.
“Combination AIS/VHF and GPS antenna for Class B transponders which makes for a super quick and high performance installation.”
“This smart NMEA to WiFi gateway allows tablets & mobile devices to connect to existing on board GPS, AIS and instrument systems.”
“Patented zero loss technology lets you share your main VHF antenna with the VHF radio, FM radio and AIS. Compatible with transponders and receivers.”
“Perfect for PC based navigation systems with USB drivers for PC, MAC and linux.”
“Connects to any NMEA AIS compatible chart plotter and adds an AIS overlay. Simple to install, highly sensitive dual channel design that’s easy to install with Garmin, Raymarine, Standard, Lowrance, Simrad, Furuno etc plotters.”
“An easy to install Class B AIS transponder with plug ‘n play NMEA 2000 interface. Built in GPS antenna and ideal for use on smaller yachts and boats like RIBs and center consoles.”
