Product overview
The BWSENSING BW-MINS225E is a miniature inertial navigation system intended for integration into unmanned aircraft, robots, platform stabilization equipment and other vehicle systems. It uses CAN communication and a high-performance Kalman filtering algorithm, with temperature compensation across -40°C to +85°C. Its attitude measurement range covers pitch through ±90° and roll through ±180°. Dynamic attitude accuracy is 0.5°, static attitude accuracy is 0.01°, and heading retention accuracy is 0.3°/60s. The maximum output frequency is 500Hz.
The packaged product measures 97 × 63 × 27.2mm, while the bare-board product measures 60 × 54 × 6mm. Bare-board length and width may vary by ±1mm, with actual dimensions taking precedence. Weight including cable is 280g. Electrical integration requires a 9-36V DC supply; operating current is 30mA, reaching a maximum of 40mA. The operating temperature range is -40 to 85°C, and the storage range is -55 to 100°C. Shock resistance is 2000g for 0.5ms, three times per axis.
