Abstract

An embodiment of the present disclosure discloses a mixed positioning method based on V2X and GNSS and the device thereof. The method includes: receiving position information or short-acting ephemeris information from a V2X base station; when receiving the position information, determining current ephemeris information of location of the V2X base station according to the position information and current time information; updating ephemeris information inside a GNSS positioning receiver via the current ephemeris information, and using the updated ephemeris information to lock satellite to perform positioning; when receiving the short-acting ephemeris information, updating ephemeris information inside a GNSS positioning receiver via the short-acting ephemeris information, and using the updated ephemeris information to lock satellite to perform positioning. The V2X technology and GNSS technology are combined to be used in mobile vehicle wireless positioning scene, improves speed of updating short-acting ephemeris, and is independent from mobile communication network and enormous and complex ephemeris algorithm, which saves positioning time and data traffic charge, improves the positioning performance.
