The AISWatchMate RX incorporates an internal high performance two channel AIS receiver with the award winning AISWatchMate collision avoidance display. Vesper Marine has designed the AISWatchMate RX to help avoid collisions at sea. Using the Universal Shipborne Automatic Identification System (AIS) the AISWatchMate RX displays data from all AIS equipped vessels in your vicinity. Audible warning alarms are sounded if a potentially dangerous situation exists.

The alarm sounds whenever a ship is detected that will come dangerously close even though the ship may still be many miles away. You are alerted immediately with the closest point of approach (CPA) and the time until CPA.

Unique and customisable alarm and filter settings help to eliminate false alarms. Ships and alarms are displayed in a prioritised order assisting you to safely navigate in crowded shipping areas.

The AISWatchMate RX has a built-in AIS receiver. It can be interfaced to other on-board electronics and will provide full AIS output. However, it is not necessary to connect it to anything other than a GPS.

 

Integrated AIS Receiver	Includes a built-in two channel parallel AIS receiver. This high performance receiver means greater range and increased safety. It also makes installation easier. No external "black boxes" to mount, power and wire. Just plug in a VHF antenna and connect the AISWatchMate RX to your GPS.
Target Plot	Provides a radar-like display of all vessels within the selected range. The display can be oriented north-up or heading-up so it's very easy and natural to interpret. Dangerous and lost targets are readily identified.
Graphical Plot Shows Crossing Situations	Shows the relative position of a target vs. your vessel at the closest point of approach. This provides a graphical view of the crossing situation and clearly indicates whether a target will pass ahead or behind.
CPA and TCPA	Computes the closest point of approach and time until CPA. Alarms may be based on these and other factors.
Bearing and Range	Computes the bearing and range to each vessel. Bearing can be displayed in magnetic to facilitate easy visual identification using your compass and binoculars. Bearings can alternatively be displayed in true or relative to your vessel's heading.
Prioritization	Vessels and alarms are presented in priority order.
Filtering	In crowded operating areas the AISWatchMate RX eliminates clutter and false alarms with sophisticated filtering options.
Identify your "fleet"	Targets marked as members of your fleet are displayed with a special icon. Use this to indicate your friends or vessels you commonly work with.
CPA alarm	Triggers alarm if a vessel will come too close. Full control of alarm parameters.
Guard alarm	Sounds alarm if any vessel comes within the specified range. Both CPA alarms and guard alarms may be used together.
External alarm trigger	In addition to the internal alarm, an external buzzer, alarm, or signal light can be interfaced without requiring any additional relays (max 2A).
Consise and easy to read displays	Uncluttered easy to read display shows all available AIS data.
Class A and class B	Displays AIS data received from all class A and class B transponders.
Safety messages	Displays received AIS Broadcast Safety Messages. These messages may contain important safety, navigation, weather, or shipping information.
Aids to navigation	Full support for AIS aids to navigation including off-position and virtual aid indicators.
Meteorological and hydrographic display	Displays real-time wind, current, tidal and much more in areas where this information is broadcast.
GPS repeater	Displays GPS satellite status and navigation data such as your position, heading, course and speed.
GPS failure alert	Alerts you if your GPS stops working.
Large backlit LCD	Adjustable daylight viewable backlit 125mm (5") LCD.
Easy to use	Four buttons control all features. Each button is clearly labeled on-screen. Buttons are backlit for night time use and illumination brightness is controllable. Each setting has on-screen help.
Ultra-Low power consumption	Designed for minimal power consumption the AISWatchMate RX is extremely well suited for energy conscious vessels.
