Attitude measurement system
Product Features
MS-100A0 is a three-degree-of-freedom attitude based on micro-mechanical technology (MEMS)
Measurement system, built-in high-performance MEMS gyroscope and MEMS accelerometer, through the filtering algorithm calculates the pitch angle, roll angle and heading angle of the carrier in real time. also optionally matched with a magnetometer to achieve high-precision north finding, and output 3-axis angular velocity and 3-axis acceleration is used for motion control.
