Abstract

An inertial sensing compensation and calibration processing system includes an attitude and heading reference unit, an upper cover, a lower shell, a first damping unit, and a second damping unit. The attitude and heading reference unit includes a body and a connecting interface. The body has a gyroscope, an accelerometer, and a magnetometer. The connecting interface is connected to the gyroscope, accelerometer, and magnetometer on one side of the body. The upper cover is disposed on a first side of the attitude and heading reference unit. The lower shell is disposed on a second side of the attitude and heading reference unit, with the first and second sides being opposite sides. A first opening in the lower shell corresponds to the upper cover. The first damping unit is disposed between the attitude and heading reference unit and the upper cover. The second damping unit is disposed between the attitude and heading reference unit and the lower shell. The upper cover closes to the first opening in the lower shell.
