Product Description
The IMU6 inertial measurement unit consists of three-axis gyroscope,
three-axis accelerometer, 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, the three-axis acceleration and the
three-axis tilt angle of the carrier. And output the gyro,
accelerometer and the inclination data after error compensation
(including temperature compensation, installation misalignment
angle compensation, nonlinear compensation and etc) through RS-422
serial port according to an agreed communication protocol.
