Abstract

The embodiment of the invention provides a hybrid location method and device based on V2X and GNSS. The method comprises: receiving the position information or short-acting ephemeris information from a V2X base station; when the position information is received, determining the current ephemeris information of the position where the V2X base station is located according to the position information and the current time information; updating the ephemeris information in a GNSS location receiver through the current ephemeris information, and locking a satellite for location through adoption of updated ephemeris information; and when the short-acting ephemeris information is received, updating the ephemeris information in a GNSS location receiver through the short-acting ephemeris information, and locking a satellite for location through adoption of updated ephemeris information. Through combination of the V2X technology and the GNSS technology, the hybrid location method and device based on V2X and GNSS are applied to the scene of mobile vehicle wireless location so as to improve the speed of updating the short-acting ephemeris, save the location time and flow cost and improve the location performance without depending on the mobile communication network and huge and complex ephemeris algorithm.

Description

Technical field [0001] The embodiments of the present invention relate to the technical field of satellite positioning, and in particular to a hybrid positioning method and device based on vehicle to outside information interaction (Vehicle to X, V2X) and GNSS. Background technique [0002] Global Navigation Satellite System (Global Navigation Statellite System, GNSS) refers to all satellite navigation systems, including global, regional and enhanced. The current GNSS includes the United States' Global Positioning System (GPS), Russia's Glonass (Russian GNSS abbreviation Glonass), Europe's Galileo (Galileo) and China's Beidou satellite navigation system. The Beidou satellite navigation system is a satellite navigation system with independent intellectual property rights in my country. It has the characteristics of two-way communication and therefore has obvious development advantages. [0003] The working principles of different GNSS are basically the same. To put it simply, any ...
