Vehicle Grade MEMS IMU Replacing MS313C for Guidance Control and Attitude Measurement
The U2500 high-dynamic MEMS attitude and heading reference unit is a highly reliable and cost-effective six-axis MEMS inertial attitude and heading reference unit, widely applicable to navigation, control, and measurement fields represented by robotics. The U2500 series attitude and heading reference units integrate high-performance MEMS gyroscopes and MEMS accelerometers within an independent structure. The devices undergo compensation for full temperature parameters, zero-point, scale factor, non-orthogonal error, and acceleration-related terms, ensuring high measurement accuracy over an extended period. The three-axis MEMS gyroscopes of the attitude and heading reference unit sense the angular motion of the carrier, while the three-axis MEMS accelerometers sense the linear acceleration of the carrier, outputting the carrier's attitude information through navigation solution.
