The product consists of MEMS inertial measurement unit, satellite positioning receiver, etc. It applies MEMS device temperature error compensation, system level self-calibration and error compensation, dual- antenna heading output delay compensation and heading angle fusion, INS/GNSS combined navigation tightly-coupled filtering and sequential coherence processing, and non-orthogonal on-line compensation of the IMU body, etc., to real-time measure and output high-precision information about the carrier position, speed, attitude, angle and other navigation parameters, which can be externally connected to the vehicle speedometer. It can measure and output high-precision carrier position, speed, attitude, angle and other navigation parameters in real time, and can be connected to vehicle tachometer externally.
