AIT5000 is a Class B+ AIS transponder. It uses the new AIS standard using SOTDMA technology and has a power of 5W instead of 2W. SOTDMA technology is also used by AIS Class A transponders and so the AIT5000 has the same priority when it comes to reserving a slot, ensuring that it is always able to transmit.
The transmission speed is up to every 5 sec instead of 30 sec. This new technology is therefore useful for sailors who need the best possible performance, for very fast motorboats and also for non-commissioned commercial vessels.
