3 Working principle
The inertial measurement unit is composed of three accelerometers and three gyroscopes. It is responsible for measuring the acceleration and angular velocity of the carrier and sending these information to the information processing circuit. The information processing circuit uses the acceleration and angular velocity measured by the inertial measurement unit for navigation settlement, and takes the satellite navigation information received by the GNSS receiver as the reference for integrated navigation, The navigation error of inertial navigation is corrected, and the navigation information is output through the information interface circuit.
