Product overview
The BWSENSING BW-AH425C is an attitude and heading reference system for integration into UAVs, unmanned ground vehicles, stabilization equipment and robotic systems. It supports both dynamic and static measurement and communicates through CAN, with a maximum output frequency of 500Hz. Heading accuracy is 0.3°, and roll and pitch accuracy is 0.2°. Its tilt measurement range extends to ±90° in pitch and ±180° in roll. Additional applications include satellite tracking, underwater robot navigation, drilling equipment measurement and control, and marine survey instruments.
The packaged product measures 60 × 59 × 29 mm, while the bare-board product measures 44 × 35 × 11 mm. Bare-board length and width may have ±1mm error, with actual product dimensions taking precedence. Electrical requirements are 9–36V DC and 30mA operating current, reaching 40mA maximum. The temperature-compensated system operates from -40 to 85°C and has a storage range of -55 to 100°C. Shock resistance is 2000g for 0.5ms, three shocks per axis; insulation resistance is at least 100 megohms.
