Product overview
The Wuxi Beiwei Sensing Technology BW-AH300 is an attitude and heading reference system for applications including unmanned aircraft, unmanned vehicles, platform stabilization and robot control. Its physical envelope measures 60 × 59 × 29 mm, and its 280 g weight includes the cable. Integration choices include selectable RS232, RS485 or TTL output. The hardware combines attitude measurement specifications with gyroscope and three-axis accelerometer specifications, providing defined measurement ranges for integration into a larger vehicle or instrument.
Heading accuracy is 0.5°, while roll and pitch accuracy is 0.3°, with pitch coverage of ±90° and roll coverage of ±180°. The gyroscope measures up to ±400°/sec with 100 Hz bandwidth; the accelerometer range is ±3.6 g on each axis. Temperature compensation accompanies a -40°C to +85°C temperature range. Shock resistance is specified at 2000 g for 0.5 ms, three times per axis. Accelerometer bias stability figures carry separate time conditions at 25°C.
