Problems solved by technology

Because these satellites are always in motion, there is an error in the geometry of the triangulation
Another problem with satellite positioning and navigation is that the signal is very weak, the signal cannot enter buildings and is easily interfered by the atmosphere and ionosphere
The inaccuracy of the satellite signal receiver's own clock will also lead to positioning errors

Abstract

The invention provides a satellite positioning system and a positioning method, which relate to the technical field of satellite positioning. The satellite positioning system comprises a front-end processing server, a network big data sharing platform and a user server wherein the front-end processing server is used for gridding a coverage area of a cors base station, and calculating coordinate errors of grid vertexes; the network big data sharing platform is used for acquiring and storing coordinate error values obtained by the front-end processing server; the user server obtains a coordinate correction value through checking the coordinate error values obtained by network big data sharing platform, and realizes precise positioning; and the front-end processing server is connected with the network big data sharing platform by means of a communication link, and the user server is connected with the network big data sharing platform through an Internet network. The satellite positioning system and the positioning method are capable of using duplicate data and historical data on the premise of precise positioning, saving lookup time, improving efficiency, reducing cost, and improving information flowability.

Description

technical field [0001] The invention relates to the technical field of satellite positioning, in particular to a satellite positioning system and a positioning method. Background technique [0002] At present, satellite positioning technology has been widely used at home and abroad. Since the transmission and reception of satellite signals are easily affected by the environment (blocked by terrain and ground objects), the positioning accuracy is reduced, especially in large cities with tall buildings and overpasses. The positioning error of satellite positioning signals is too large in many places. Can't even locate. [0003] Current positioning systems include the GPS system of the United States, the Galileo system of Europe, the GLONASS system of Russia, and the Beidou system of China. These systems are composed of satellites in low Earth orbit. The accuracy of the positioning is determined by the geometry of the triangulation. Because these satellites are always in mo...
