Navigation Grade MEMS IMU with 3 Axis Accelerometer Gyroscope

1.1 Composition and function

The inertial measurement unit consists of three-axis gyroscope, three-axis acceleration meter, three-axis tilt angle (without this sensor by default), temperature sensor, signal processing board, structure and necessary software, and is used to measure the three-axis angular rate, three-axis acceleration and three-axis tilt angle of the carrier. And output the gyro, accelerometer and inclination data after error compensation (including temperature compensation, installation misalignment angle compensation, nonlinear compensation and etc) through an RS-422 serial port according to an agreed communication protocol.
