The G2183 is a highly-accurate GPS antenna—WAAS / EGNOS enabled. It is one of the first true 10Hz GPS Antennas made available. Scoring high in sensitivity, it delivers quick signal acquisition, reliable positioning, and accurate speed and course-over-ground readings. The G2183 can connect to both NMEA 0183 or 2000® networks, as the unit outputs both protocols simultaneously. And its compact size makes it easy to flush mount, pole mount, or rail mount. Rugged for all marine environments, the IPX6 waterproof housing can withstand virtually any condition Mother Nature throws at it.

Whether you are offshore fishing or just enjoying family time on the water, feel confident and comfortable that the H2183 is your reliable source for heading information. The solid-state, three-axis compass combined with Airmar’s additional advanced sensors and software provide unparalleled performance.

What sets the H2183 apart from the competition is its ability to maintain 2° of heading accuracy under dynamic motion conditions such as steep heeling, hard turns, and rough seas. Heading integrated with three-axis rate gyro and three-axis accelerometer data allows the H2183 maintain 2° of accuracy even if the vessel is pitching and rolling up to 30°. This level of accuracy is perfect for interfacing with autopilots, chart plotters, and radar systems. The H2183’s innovative circular design easily mounts and aligns on ANY angled bulkhead. Designed for simultaneous use with NMEA 0183 and NMEA 2000® devices, the waterproof, easy-to-install sensor can be wired into both NMEA 0183 and NMEA 2000 networks on the vessel with just a single cable.

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.

The best performance in ANY sea condition!

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.
