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. As well as fast power boats and smaller non-mandated commercial vessels. It still inter-operates with existing Class B and Class A systems.
The main VHF antenna can be shared with the VHF, AIS and FM radio due to the patented ZeroLoss VHF-AIS antenna splitter incorporated within the AIT5000. furthermore, it also has a wireless interface for connecting to iPads, smartphones and tablets.
The AIT5000 creates a secure, password protected, local Wi-Fi network which allows AIS and GPS data to be sent to popular iOS and Android apps such as Navionics, iSailor, Weather4D, SailGrib, iNavX, TimeZero and more. These apps offer a detailed overlay of local AIS targets all updated in real-time. Depending upon the app, you can click on a target and can see identity as well as collision avoidance data. This includes CPA (closest point of approach) and TCPA (time to closest point of approach).
The tablet’s browser (Safari, Chrome, etc.) provides a simple, embedded web interface for one time programming of the boat’s identity and physical dimensions, required of all AIS transponders. Silencing the transmission and setting up wireless parameters such as passwords can also be done via this web interface.
Moreover, if you want the wireless interface to also transmit your NMEA 2000 data, please add our iKonvert which is an NMEA 2000 to NMEA 0183 converter. The wireless interface can connect up to 7 devices.
The AIT5000 has the option of an AIS SART alarm which is great for use with personal AIS MOB devices. Now works with the popular Navionics Boating App for Apple iOS and Android to display GPS and AIS data on your Navionics charts.
Class B+ is a new generation of AIS functionality based on SOTDMA (self organised TMDA) messaging rather than the simpler CSTDMA (carrier sense TDMA). For instance, this guarantees your AIS transmission will get a time slot, even in areas of very high traffic density. Moreover, it also specifies a 5W transmission power (compared with 2W for Class B) and a transmission rate that increases as the vessel moves faster. When the vessel is moving, the transmission rate is fixed at every 30 seconds with regular Class B protocol. 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.
