Product overview
The BWSENSING BW-MINS427 is a packaged micro inertial navigation system for integration into unmanned aircraft and other moving platforms. Its physical envelope measures 60 mm long, 59 mm wide and 29 mm high, providing a compact component footprint for equipment integration. The system combines gyroscope and accelerometer measurement capabilities with Kalman filtering and bias tracking for drift control. Its application scope also includes robots, platform stabilization, unmanned boats, underwater vehicles, large ships and automated guided vehicles.
Electrical integration uses a 9–36 V DC supply, with selectable RS232, RS485, TTL or Modbus output. The temperature-compensated operating range extends from -40°C to +85°C. Attitude accuracy is 0.2° dynamically and 0.01° statically, with pitch coverage of ±90° and roll coverage of ±180°. Heading holding accuracy is 0.1°/min. The accelerometer range is ±1.8 g on each axis; its bias-stability figures depend on the specified temperature and averaging interval, while gyroscope bias stability is specified across the full temperature range.
