True Heading CTRX VISION+
5W Class B-SOTDMA AIS transponder with splitter & WiFi
The new True Heading CTRX Vision+ is a modern 5 Watt AIS class B transponder, which uses the SOTDMA protocol. Just like AIS class A equipment, CTRX Vision+ participates in the time slot reservation plan, so it will always have a free timeslot available to transmit it’s position, at a higher update rate. Former types of AIS, such as our previous Graphene AIS series, are CSTDMA transponders. These first listen to determine if there is a free time slot that can be used.
