Product overview
The BWSENSING BW-MINS500 is a miniature inertial navigation system with gyroscope and accelerometer specifications, Kalman filtering and a dedicated bias-tracking algorithm for drift elimination. Its applications include UAVs, robots, platform stabilization, unmanned boats, underwater vehicles, large vessels, automated guided vehicles and special-purpose vehicles. The unit measures L60 × W59 × H29 mm. Electrical integration requires a 9–36 V DC supply, and output interface options are RS232, RS485 or TTL. Its temperature range is −40°C to +85°C with temperature compensation.
Dynamic attitude accuracy is 0.1°, while static attitude accuracy is 0.01°. Heading retention accuracy is 0.1°/min, and gyroscope resolution is 0.01°/sec. The bias-stability figures carry specific measurement conditions: gyroscope bias stability is 5°/h across the full temperature range at 10 s and 1σ. Accelerometer bias stability is 0.001 mg at 25°C over 100 s and 1σ, or 0.01 mg at 25°C over 10 s and 1σ. These separate figures distinguish static and dynamic accuracy and the accelerometer’s two measurement intervals.
