Features

Plug-And-Play

GNSS Compass is a fully plug-and-play solution with support for both NMEA 2000 and NMEA 0183. There is no configuration, setup or calibration required. Reliable position and heading in minutes.

GNSS Heading

GNSS Compass uses dual GNSS antennas to reliably determine true heading with high accuracy. It doesn't require motion to work and it isn't affected by magnetic interference.

Interface Options

GNSS Compass is available in both a serial variant and a power over ethernet variant. The serial variant supports both NMEA 2000 and NMEA 0183 for plug-and-play connection to existing marine systems, while the power over ethernet variant allows simplified power and network cabling with maximum flexibility for new applications.

Dual Frequency RTK GNSS

GNSS Compass features L1/L2 RTK to deliver real time position accuracy of 10 mm. It supports all of the current and future satellite navigation systems including GPS, GLONASS, GALILEO and BeiDou.

Time Server

GNSS Compass features a GPS disciplined oscillator allowing it to act as a high accuracy time reference for other systems. The power over ethernet variant supports both PTP and NTP for precise time synchronization across your whole network.
