The G3X system uses the latest in GPS-aided digital ADAHRS (Air Data and Attitude Heading and Reference Systems). Leveraging solid-state sensors and sophisticated attitude determination and integrity monitoring algorithms used in Garmin’s high-end G1000 system, the G3X’s ADAHRS provides highly accurate and reliable referencing of your aircraft position, rate, vector and acceleration data. Better still, the complete sensor package – ADAHRS and EIS engine monitoring¹, plus magnetometer and temperature probe – takes up just a fraction of the space and weight previously required by conventional gyro-based instrument systems.
