Compact MEMS IMU Sensor For Attitude Control In UAVs Loitering Munitions SI-MIMU300S
This product is equipped with high-precision three-axis MEMS gyroscopes and three-axis MEMS accelerometers. It can measure the attitude parameters (roll angle, pitch angle, angular velocity, and acceleration) of moving carriers. Through corresponding estimations such as nonlinear compensation, orthogonal compensation, temperature compensation, and Kalman filtering, extremely high measurement accuracy is ensured.
This product is designed to be lightweight, compact, and user-friendly, suitable for various applications such as assisted driving, autonomous vehicles, vehicle positioning and orientation, AGV cars, power line inspection, platform stabilization, surveying and mapping, precision agriculture, and more.
