Product overview
Wuxi Beiwei Sensing Technology’s BW-MINS225E is a low-cost miniature inertial navigation system for integration into unmanned aircraft, robotic equipment, vehicles and marine platforms. It combines CAN communication with a high-performance Kalman filtering algorithm and temperature compensation. Its attitude specifications distinguish 0.5° dynamic accuracy from 0.01° static accuracy, with pitch measurement through ±90° and roll through ±180°. Heading retention accuracy is 0.3°/60s, while the maximum output frequency is 500Hz.
The hardware has packaged and bare-board configurations, giving integrators two physical envelopes: 97 × 63 × 27.2 mm and 60 × 54 × 6 mm respectively. Bare-board length and width may vary by ±1mm, so the actual hardware dimensions govern installation space. Weight including the cable is 280g. Electrical integration requires 9-36V DC, with operating current of 30mA and a 40mA maximum. The operating temperature range is -40 to 85°C, and the storage range is -55 to 100°C.
