Airmar GH2183 Heading & GPS Compass

The Airmar GH2183 combines GPS positioning and highly-accurate heading information in one compact antenna. The GH2183 eliminates the need to install a GPS antenna above deck and a heading sensor below deck. Only one, above-deck installation is required, saving installation time and money. The waterproof housing protects the internal components—all of which are solid-state (no moving parts). This means the GH2183 can withstand almost any condition that exists in the marine environment.

What sets the GH2183 above the competition is our 2° heading accuracy in dynamically changing conditions—including rough seas, hard turns, and steep heeling. Airmar’s unique dynamic motion correction software is the key difference, allowing the GH2183 to maintain 2° of accuracy even if the vessel is pitching and rolling up to 30°. Also unique to the GH2183 is that the three-axis accelerometer and three-axis rate gyro are temperature compensated across the entire operating range, resulting in precise tilt and rate of turn data. The fast 10 Hz update rate, along with best-in-class heading and GPS data, make it the best choice for interfacing with autopilots, chartplotters, navigation software, and radar systems.

Note; an optional NMEA2000, NMEA0183 or combination NMEA2000 & NMEA0183 cable is required to complete this package.
