Product overview
The BWSENSING BW-MINS200 is a miniature inertial navigation system intended for unmanned aircraft, robots, platform stabilization and vehicle applications. Its packaged dimensions are 60 mm long, 59 mm wide and 29 mm high, providing a compact physical envelope for integration. Output options are RS232, RS485 or TTL, with the interface selectable for the installation. Its sensing specifications cover a gyroscope and an accelerometer with measurement on the X, Y and Z axes; processing includes Kalman filtering and a special bias-tracking algorithm for drift elimination.
Dynamic attitude accuracy is 0.5°, while static accuracy is 0.01°. The attitude measurement range covers pitch to ±90º and roll to ±180º, with heading retention accuracy of 0.3°/60s. The accelerometer range is ±1.8 g on each axis. Its bias stability is 0.001mg at 25°C over 100s and 0.01mg at 25°C over 10s, both at 1σ. Gyroscope bias stability across the full temperature range is 20°/h under the stated 10s, 1σ condition, and angular random walk is below 0.1 °/√h.
