The Comar R550NGi is an AIS & GNSS receiver (Supporting GPS & GLONASS) interfaced to an ARMv8 microcomputer. Designed for coastal monitoring applications, the R550NGi is capable of filtering and processing AIS and GNSS data and forwarding it across a network. Multiple R550 Series units can be deployed to form a complete networked monitoring solution for ports and their approaches.

The unit features both Wi-Fi and Ethernet connectivity, along with two USB-A host ports and an HDMI connector for direct display output. Unlike conventional receivers, the R550NGi can be deployed within any AIS network using proprietary software specific to that network.

Designed for commercial applications, the R550NGi incorporates Comar’s proven high-sensitivity dual-channel parallel AIS receiver alongside a commercial-grade GNSS receiver.

The R550NGi from Comar Systems: Quite possibly the most flexible, compact and powerful AIS and GNSS receiver available today.

Comar Connect Pre-installed

The R550 Series comes with Comar Connect pre-installed, making setup straightforward through a web browser on your local network. Configure your receiver, check service status and forward AIS data to up to four destinations using TCP or UDP. Message filtering, user access controls and configuration backup provide the flexibility to tailor your installation to your needs.
