Product overview
Wuxi Beiwei Sensing Technology’s BW-MINS125E is a miniature inertial navigation component for integration into unmanned aircraft and other vehicle or stabilization systems. Its architecture combines CAN communication with Kalman filtering and temperature compensation. Attitude measurement covers pitch through ±90° and roll through ±180°, with 1° dynamic accuracy and 0.01° static accuracy. Heading retention accuracy is 0.5°/60s, while the maximum output frequency is 500Hz. These separate specifications distinguish its moving and stationary measurement capabilities.
The packaged product measures 97 × 63 × 27.2 mm and weighs 280g including its cable. A bare-board format measures 60 × 54 × 6 mm, with a possible ±1mm variation in length and width that must be allowed for in integration. Electrical requirements are 9-36V DC and 30mA operating current, rising to a maximum of 40mA. Operating temperature spans -40°C to 85°C, while storage extends from -55°C to 100°C. Shock resistance is specified at 2000g for 0.5ms, three times per axis.
