Product overview
The Wuxi Beiwei Sensing Technology BW-AH527C is a Modbus attitude and heading reference system for dynamic and static measurement. Its applications include unmanned aircraft, unmanned vehicles, platform stabilization, satellite tracking and robot control, alongside underwater robot navigation, marine surveying instruments and drilling equipment measurement and control. Selectable outputs comprise RS232, RS485 or TTL. Roll and pitch accuracy is 0.1°, and heading accuracy is 0.2°. The tilt measurement range extends to ±90º in pitch and ±180º in roll.
The packaged unit measures 60 × 59 × 29 mm, while the bare-board form measures 44 × 35 × 11 mm; bare-board length and width may vary by ±1 mm, with the physical unit determining actual dimensions. Power requirements are 9-36V DC and 30mA operating current, rising to 40mA maximum. Temperature compensation accompanies a -40 to 85°C operating range, with storage rated from -55 to 100°C. The gyroscope has a ±400°/sec range and 100Hz bandwidth; maximum output frequency is 500Hz.
