HT-GC-01 is a heading reference (gyrocompass). It employing high precision dynamically tuned gyro (DTG) and quartz accelerometer to provide accurate Attitude and heading in all dynamics.It is not influenced by external magnetic or ferrous influences. High-performance real-time outputs of true heading, roll, pitch as well as acceleration and rate of turn.

2. Product composition
Triaxial dynamic gyro, Triaxial accelerometer, Data acquisition and processing module, Secondary power, Optically coupled isolator serial input and output circuit, Others.
3. Work process
After connect power as required and Starting, product enters the warm-up interval, after the warm-up had ended, the product enters the initial self-alignment interval. Since power on products, after 30 minutes, this product can output real-time Azimuth, Roll & Pitch.
