At present, satellite navigation systems can provide centimeter-level positioning when the satellite signal is good, but the positioning accuracy in weak signal environments such as tunnels, tree occlusion, high-rise buildings and viaducts has been greatly reduced. In the smart Internet of Vehicles service platform, the vehicle's driving trajectory drifts frequently. Improving the positioning accuracy of vehicles in complex scenarios is very important for improving the travel path management of government and enterprises. This paper studies the application of INS and multi-navigation technology combined inertial guidance module to the positioning accuracy of on-board terminals, that is, the integration of GPS ,Beidou , INS inertial navigation, and the high-performance on-board combination inertial guidance module based on GNSS/INS combined navigation positioning is connected to the on-board navigation, making full use of the advantages of the inertial navigation system and the satellite navigation system. With high-precision six-axis inertial device and inertial algorithm, the optimal navigation results are obtained without odometer or speed signal access. Especially when the satellite navigation system is unable to work, the inertial navigation system is used to make the navigation system continue to work, ensure the normal operation of the navigation system, and improve the stability and reliability of the on-board navigation system.
