Overview
The patented 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.

FAQs
What is the recommended location for installation?
It requires only one above-deck installation.
How accurate is the heading sensor under static and dynamic conditions?
It provides better than 1° accuracy static, and 2° RMS accuracy in dynamic conditions.
How is pitch and roll information provided?
A three-axis accelerometer provides pitch and roll data, with up to 0.1° resolution and <3° dynamic accuracy.
How is compass calibration performed?
Compass calibration can be done easily on any display or PC.
Does the GH2183 support WAAS GPS for enhanced positioning?
Yes, WAAS GPS provides latitude, longitude, and related data.
What is the waterproof rating of the GH2183 housing?
The GH2183 housing is rated IPX6 for waterproofing, protecting internal solid-state components in harsh environments.
Is the GH2183 suitable for use in exposed marine environments?
Yes, the waterproof and solid-state GH2183 is designed to withstand almost any condition in the marine environment.
How quickly does the three-axis compass settle on a new heading?
The three-axis compass has a settling time of 1 second, which is adjustable as needed.
