Product overview
The BWSENSING BW-MINS125(-E) is a CAN bus micro inertial navigation system intended for applications including unmanned aircraft, robots, platform stabilization and special-purpose vehicles. The unit measures 115 × 63 × 28.2 mm and weighs 0.4 kg including its cable; weight including packaging is 0.48 kg. Electrical integration requires a 9-36V DC supply, with operating current of 30mA and a maximum of 40mA. Its interfaces include CAN bus output, serial communication from 2400 to 115200 baud and a high-performance binary digital protocol.
Attitude measurement has dynamic accuracy of 1° and static accuracy of 0.01°, with 0.01° resolution. The tilt range covers pitch of ±90° and roll of ±180°, while heading retention accuracy is 0.5°/60s. Maximum output frequency is 500Hz. Operating temperature spans -40 to 85°C, and storage temperature spans -55 to 100°C. The system incorporates a special bias-tracking algorithm for drift elimination and high-level EMC protection. Shock resistance is specified as 2000g for 0.5ms, with three shocks per axis.
