Product overview
The Wuxi Beiwei Sensing Technology BW-MINS525 is a packaged micro inertial navigation system for applications including UAVs, robots, platform stabilization and marine vehicles. Its sensing functions include a gyroscope and a three-axis accelerometer, with output through a CAN interface. The package measures 60 mm long, 59 mm wide and 29 mm high. Electrical supply is 9–36V DC, and the temperature range is -40℃ to +85℃ with temperature compensation. Processing includes special bias tracking for drift elimination and high-performance Kalman filtering.
Attitude performance comprises 0.1° dynamic accuracy and 0.01° static accuracy, with measurement ranges of ±90º in pitch and ±180º in roll. Heading holding accuracy is 0.1°/min. The gyroscope has 0.01°/sec resolution, full-temperature bias stability of 5°/h under the 10s, 1σ condition, and angular random walk below 0.1 °/√h. Accelerometer range is ±1.8 g on each axis. At 25℃ and 1σ, accelerometer bias stability is 0.001mg under the 100s condition and 0.01mg under the 10s condition.
