ProductName: HT-GC-01 GYROCOMPASS
Content:
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.
