50 AIS
Automatic Identification System (AIS)
Operating in the VHF maritime band, the AIS system enables the
wireless exchange of navigation status between vessels and shore-
side traffic monitoring centres. Commercial ships, ocean-going vessels
and recreational boats equipped with AIS transmitters broadcast AIS
messages that include the vessel’s name, course, speed and current
navigation status.
AIS500 TRANSCEIVER AND
AIS250 RECEIVER
AIS250 Receiver Module
The Raymarine AIS250 Receiver module is a ‘listen only’ dual-channel
AIS receiver that easily integrates with Raymarine multifunction systems.
Switched dual channel, multiplexed system – a single receiver uses
sophisticated software to monitor AIS Class A and B transmissions over
standard VHF frequencies.
Overlay AIS targets on Raymarine multifunction displays in both chartplotter
and radar modes.
AIS target tracking enhances your situational awareness by monitoring a
target’s name, course, speed and navigation status.
Reconcile AIS targets with radar targets for added safety.
Built-in VHF/FM antenna splitter. No additional antenna required.
Two NMEA 0183 input and two NMEA 0183 output ports with a built-in
multiplexer for easy installation.
