Compact MEMS IMU for UAV systems
,High-precision MEMS IMU 3°/h stability
,STIM300 replacement IMU for munitions
This unit integrates high-precision three-axis MEMS gyroscopes and three-axis MEMS accelerometers to measure real-time carrier attitude parameters, including roll angle, pitch angle, angular velocity and acceleration. By adopting comprehensive calibration algorithms — including nonlinear compensation, orthogonal compensation, full-temperature compensation and Kalman filtering — the system achieves outstanding measurement accuracy and stable inertial data output.
Featuring ultra-compact size, lightweight design and easy integration, the sensor is widely applicable for assisted driving, autonomous vehicles, vehicle positioning and orientation, AGV robots, power line inspection, platform stabilization, surveying and mapping, as well as precision agriculture scenarios.
