Comar SLR-350Ni

Specifically designed for coastal monitoring of AIS-equipped vessels, SLR-350Ni is a new take on traditional AIS receivers amping up the functionality of the successful Comar SLR-350N.

 

This compact dual-channel synthesized VHF receiver is based on the Raspberry Pi 3 mini computer. With built-in Ethernet, WiFi and USB interfaces, it can be connected to any wired or wireless network and start streaming data to up to five user-defined destinations excluding the reserved MarineTraffic data stream.

 

The unit is capable of receiving and decoding all AIS transmissions from vessels fitted with Class A or Class B AIS transceivers, Aids to Navigation, and SART. Using compatible software, AIS data transmitted from ships within range can be displayed on the screen giving a visual representation of all traffic within VHF range. The web UI of the receiver also enables local plotting.
