Product overview
The Wuxi Beiwei Sensing Technology BW-AH225 is an attitude and heading reference system for integration into unmanned aircraft and other equipment requiring orientation measurements. Its architecture includes gyroscope and accelerometer sensing, with CAN output for connection to a host system. The compact enclosure measures 60 × 59 × 29 mm, and the specified weight is 280 g including cable. This configuration is an instrumentation component for integration into a larger platform.
The BW-AH225 provides 0.8° heading accuracy and 0.5° roll and pitch accuracy, with pitch coverage of ±90° and roll coverage of ±180°. Its gyroscope measures rates up to ±400°/sec, while the accelerometer range is ±3.6 g on each axis. Temperature compensation accompanies the -40°C to +85°C temperature range. Shock resistance is specified at 2000 g for 0.5 ms, three times per axis; gyroscope and accelerometer stability figures carry distinct timing, temperature and statistical qualifications.
