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 an electronic compass below deck. Only one installation above the deck 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 the 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.
