Problems solved by technology

[0002] At present, smart vehicles mainly obtain differential satellite navigation data from the server through the installed positioning application. This method requires that the positioning application of a specific service provider must be installed in the smart vehicle, and the corresponding service provider must be received only when the network quality is good. Therefore, it is easily affected by the quality of the operator's network. In addition, the erection position of the continuous operation reference station deployed by the current server is relatively fixed and the number is limited, so it cannot accurately reflect the differential satellite navigation data of intelligent vehicles. Make the positioning accuracy of intelligent vehicles lower

Abstract

The embodiment of the invention provides a differential positioning method, device and system. The differential positioning method comprises the following steps of: acquiring a navigation informationrequest of a target roadside device, wherein the navigation information request comprises identification information of the target roadside device; determining geographical position information of thetarget roadside device according to the identification information; determining first differential satellite navigation information of the target roadside device according to the geographical position information of the target roadside device; and sending the first differential satellite navigation information to the target roadside device, so that an intelligent vehicle performs positioning according to the first differential satellite navigation information. According to the technical scheme, the positioning accuracy of the intelligent vehicle can be remarkably improved.
