Product overview
The Wuxi Beiwei Sensing Technology BW-MINS125(-E) is a micro inertial navigation system for integration into unmanned aircraft, robotic systems, vehicles and marine equipment. Its functions include attitude measurement and heading holding, with CAN-bus output and a special bias-tracking algorithm for drift elimination. The hardware measures 115 × 63 × 28.2 mm and weighs 0.4kg including its cable, establishing the space and mass requirements for installation. Its application scope also includes platform stabilization, unmanned boats and underwater vehicles.
Electrical integration requires a 9-36V DC supply, with operating current specified as 30mA and a maximum of 40mA. Output frequency reaches 500Hz, while serial communication supports 2400 to 115200 baud using a binary high-performance protocol. Attitude accuracy is 1° dynamically and 0.01° statically, with pitch coverage of ±90° and roll coverage of ±180°. Heading holding accuracy is 0.5°/60s. Operation spans -40 to 85°C; storage spans -55 to 100°C. Packaged weight is 0.48kg, and shock resistance is specified at 2000g for 0.5ms, three times per axis.
