Description
KP-25A with built in 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 KP25A AIS transceiver:
Features of this model:
- AIS targets overlaid on the chart
- Class B+ SOTDMA
- 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.
- Has
NMEA0183 and NMEA2000. For Wi-Fi add an NMEA to wi-fi converter. See
our YakBitz 0183 to wi-Fi converter or our Onwa 0183/2000/wi-fi converter.
