R400NG Network AIS Receiver with Ethernet and GPS

SKU: COM-0007


The R400NG is an AIS receiver unit with a built-in GPS Receiver, Ethernet interface and USB port, and designed specifically for coastal monitoring of AIS-equipped vessels.

Connected to an Ethernet Network and directly or via a Router to a PC running compatible software, AIS data transmitted from ships within range can be displayed on a screen, visually interpreting the traffic within the VHF range. The unit can also be mounted at a remote location, and AIS data is sent over the Internet to a fixed IP address for use on a dedicated server.

The R400NG has been specifically designed for use by the professional market and uses Comar’s well-proven and internationally specified high-sensitivity dual-channel parallel receiver.
