AIS Receiver (easyAIS3 series)



Coming soon


Product information

The easyAIS3 is the new AIS receiver in the Weatherdock product family. The small size of such a device makes it possible for the easyAIS3 to be a perfect companion on the next charter cruise. Via USB cable, the 5 Volt power supply can be made from a power bank or a laptop. In addition, the connection of the power supply to the electrical system on board is also possible.

The device has a 2-channel receiver, with which the two AIS frequencies are permanently monitored. With a VHF antenna, a mobile AIS system can be set up on the charter vessels if no AIS is available.

The AIS signals transmitted by commercial vessels (Class A) and pleasure boats (Class B) are received by the easyAIS3, converted into a NMEA protocol and forwarded to a connected chart plotter, where the received ship positions can be displayed in real time. The same is possible via USB connection to a PC or laptop with AIS capable software.

As a permanent installation aboard your own ship, you need a VHF antenna to receive the AIS data, which is placed as high as possible on the ship. For a possible simultaneous use of the VHF antenna for AIS and VHF radio an antenna splitter, at best the easySPLIT3, is needed.
