Product overview
The BWSENSING BW-MINS527 is a packaged micro inertial navigation system for integration into UAVs, robots, marine vehicles and stabilization equipment. Its sensing specifications cover a gyroscope and accelerometer, with Kalman filtering and a special bias tracking algorithm for drift elimination. Dynamic attitude accuracy is 0.1°, while static accuracy is 0.01°. The attitude measurement range covers pitch to ±90º and roll to ±180º. Heading holding accuracy is 0.1°/min, and gyroscope resolution is 0.01°/sec. The product serves as a navigation component within a larger vehicle or system.
The package measures 60 mm long, 59 mm wide and 29 mm high, defining the physical space needed for integration. It accepts 9–36V DC and offers selectable RS232, RS485, TTL or Modbus output. Its temperature range is -40°C to +85°C with temperature compensation. The accelerometer measures ±1.8 g on the X, Y and Z axes. Accelerometer bias stability is 0.001mg at 25°C, 100s and 1σ, or 0.01mg at 25°C, 10s and 1σ. Gyroscope bias stability across the full temperature range is 5°/h under the specified 10s, 1σ condition.
