Product overview
The Wuxi Beiwei Sensing Technology BW-MINS200 is a micro inertial navigation system intended for integration into unmanned aircraft, robots, marine vehicles and stabilization platforms. Its packaged body measures 60 mm long, 59 mm wide and 29 mm high, defining the space occupied by the unit. Its sensing specifications cover gyroscope performance and acceleration measurement on the X, Y and Z axes. Output interface choices are RS232, RS485 or TTL, providing selectable electrical integration options.
The BW-MINS200 combines Kalman filtering with a special bias tracking algorithm for drift elimination. Its attitude specifications distinguish 0.5° dynamic accuracy from 0.01° static accuracy, with pitch measurement limited to ±90º and roll to ±180º. Heading retention is specified as 0.3° over 60 seconds. The accelerometer range is ±1.8 g on each axis, while its two bias stability values apply at 25℃ with different measurement durations; those conditions matter when comparing integration requirements.
