MS-100A0 Attitude Measurement System

Short Description:

MS-100A0 is an advanced three-degree-of-freedom attitude measurement system based on micro-mechanical technology (MEMS). It incorporates a high-performance MEMS gyroscope and MEMS accelerometer, which work in tandem to accurately calculate the pitch angle, roll angle, and heading angle of the carrier in real-time. Additionally, it offers the option to integrate a magnetometer for achieving high-precision north finding. The system provides output data on 3-axis angular velocity and 3-axis acceleration, which can be effectively utilized for motion control purposes.
