Attitude And Heading Reference System

TY421 attitude and heading reference system is a low cost system which can be used in simple vehicle navigation “Satcom on the move” antenna platform stabilization. This MEMS gyro, MEMS accelerometer, as well as algorithm suitable for conical scanning of antenna and satellite data correction this system uses, makes the requirement of hardware reduce greatly. Finally, the combination of dual antenna GPS or magnetometer can provide precise navigation and position info for users.

2. Features

(1) Auto-output of navigation information

(2) Meet the requirement of accurate measurement of attitude angle of aircraft, when in large maneuver flight and hovering.

(3) Small volume and weight.
