SKG123ND is a high-performance vehicle-mounted integrated navigation module for the field of vehicle-mounted navigation. The module contains a high-performance chip which supports GPS, Beidou, GLONASS, Galileo,QZSS satellite reception and L1+L5 dual-frequency positioning, three-axis gyroscope, three-axis acceleration, etc. Through the online adaptive integrated navigation algorithm, the SKG123ND provides real-time and high-precision vehicle positioning, speed measurement, and attitude measurement information. When the signal precision of GNSS system decreases or even the satellite signal is lost, SKG123ND utilizes pure inertial navigation technology without resorting to odometer information. It can also carry out high-precision positioning, speed measurement, and attitude measurement on the vehicle carrier alone for a long time. The module can directly output the total mileage, which is convenient for customers to measure mileage.
