Product overview
The Wuxi Beiwei Sensing Technology BW-IMU600 is an inertial measurement unit for integration into navigation, attitude measurement and stabilization systems. Its applications include unmanned aircraft, underwater robot navigation, autonomous-driving navigation platforms, pipeline surveying and model attitude-angle measurement. The hardware combines gyroscope and accelerometer sensing in an external envelope measuring 44.8 × 38.6 × 21.5 mm. This makes its procurement scope an inertial sensing component for a host system, rather than a complete flight platform or an airframe kit.
Integration uses an RS422 output interface, with a maximum output frequency of 500Hz and a startup delay of 200ms. The standard accelerometer range is ±20g, with ±5g and ±50g alternatives; the gyroscope range is ±300°/s. Orthogonality compensation and temperature compensation are included. The temperature range is -40°C to +85°C. Gyroscope bias figures depend on measurement conditions: room-temperature stability is below 0.3°/h with 10s smoothing, while full-temperature bias is 3°/h without temperature compensation and below 0.3°/h with compensation.
