Attitude and Heading Reference System
The attitude and heading reference system has the fiber optic gyros as sensors. The system provides the autonomous determination of pitch and roll angles. The external magnetic compass provides the heading determination. The system can work both in autonomous inertial mode and GPS integrated mode. Due to original navigation algorithm, the system is capable to calculate the autonomous coordinates in dead reckoning mode during limited time interval (1 hour).
