Product overview
The BWSENSING BW-MINS400 is a packaged micro inertial navigation unit for applications including unmanned aircraft, robots, unmanned boats and underwater vehicles, platform stabilization, and automated guided vehicles. Its sensing architecture includes a gyroscope and a three-axis accelerometer, with Kalman filtering and a dedicated bias-tracking algorithm for drift elimination. The enclosure measures 60 mm long, 59 mm wide and 29 mm high, defining the physical space required for the unit within a host system.
Electrical integration uses a 9–36V DC supply and a selectable RS232, RS485 or TTL output interface. The temperature range is -40℃ to +85℃ with temperature compensation. Attitude measurement covers pitch to ±90º and roll to ±180º, with dynamic accuracy of 0.2° and static accuracy of 0.01°. Heading retention accuracy is 0.1°/min. The accelerometer range is ±1.8 g on each axis; its two bias-stability figures apply specifically at 25℃ and use different measurement intervals.
