Abstract

The invention relates to a high-precision real-time satellite positioning method. The method is technically characterized in that a polygonal satellite positioning receiver array formed by a plurality of satellite positioning receiving mechanisms is built; each satellite positioning receiver sends respective ID and observed value coordinate to a processor module; the processor module calculates to obtain a physical geometric figure and an observed value geometric figure; the physical geometric figure and the observed value geometric figure are compared, a deviation vector caused by an error is extracted and a deviation vector function library is formed; the deviation vector is subtracted from an observed value of a satellite positioning receiver antenna phase center, thereby obtaining a corrected satellite positioning value. The high-precision real-time satellite positioning method provided by the invention is reasonable in design, can maximally eliminate positioning errors existing in the satellite positioning receivers, can remarkable improve positioning precision, has the characteristics of reasonable design, high precision, low cost, convenient use and the like, and can be extensively applied and popularized to the general civil field of high-precision real-time satellite positioning navigation.

Description

technical field [0001] The invention belongs to the technical field of satellite navigation and positioning, in particular to a high-precision real-time satellite positioning method. Background technique [0002] Satellite positioning and navigation systems mainly include GPS, Beidou, GLONASS, Galileo, etc. With the rapid development of satellite positioning technology, people's demand for fast and high-precision location information is becoming increasingly strong. At present, the application range of high-precision real-time satellite positioning and navigation is becoming wider and wider, requiring the positioning accuracy of user receivers to reach decimeter or even centimeter level. [0003] Satellite positioning receiver technology is very mature. According to known principles, satellite positioning is realized by using observations such as pseudorange, ephemeris, and satellite launch time of a group of satellites and user clock differences. To obtain the three-dimen...
