Product Description
The MEMS Inertial Measurement Unit (IMU) consists of three-axis
gyroscope, three-axis accelerometer, temperature sensor, signal
processing board, structure and necessary software, and is used for
measuring the three-axis angular rate, three-axis acceleration and
three-axis inclination angle of a carrier. And output the data
of the gyroscope and the accelerometer 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.
