Product Overview
The IMU6 inertial measurement unit integrates a three-axis gyroscope, three-axis accelerometer, temperature sensor, and signal processing board to measure angular rate, acceleration, and tilt angle of the carrier. The system outputs compensated data (including temperature compensation, installation misalignment angle compensation, and nonlinear compensation) through an RS-422 serial port using a standardized communication protocol.
