The AIS section.
All Onwa AIS products have a Class B+ AIS transceiver. Class B+ is the later version of the original Class B two Watt system but having five Watts output and using SOTDMA transmitting technology (Class B is CSTDMA). SOTDMA is superior to Class B CSTDMA, not only in being higher power, but also in enabling a transmitting vessel to access a transmission slot in the AIS system even in AIS crowded waters. Class B can reserve a slot but if the AIS system is in heavy use the slot is not guaranteed so it may not be able to transmit until a slot is available. SOTDMA also has an advantage in that the transmission is sent more frequently if the speed of the vessel increases which is highly desirable for high-speed craft such as a RIB.
Features of the built-in AIS transceiver

Class B+ SOTDMA (same technology as Class A) with guaranteed time slot allocation and transmission rate based on speed.
Receive sensitivity = > -123dBm (2 channels)
Transmit power = > +36.999 dBm (1 channel) 5 Watts
User adjustable CPA and TCPA alarms (CPA = closest point of approach, TCPA = time to CPA)
Vessel list shows a list of all AIS vessels transmitting within reception distance selecting any one will show other vessel details including: Vessel name, MMSI, Position, COG, SOG, vessel size and its distance away from your own boat. Note that any vessel calculated to be on a collision course and being inside of CPA or TCPA boundaries will trigger an alarm alert on chart screen and also in detail on the AIS screen. AIS target tracking, selecting any vessel enables tracking of that vessel, up to 10 vessels can be selected.
