Abstract

The invention discloses a method and system for improving the positioning accuracy of a navigation satellite. The method for improving the positioning accuracy of the navigation satellite includes the following steps that: positioning data are calculated according to satellite signals obtained by a GNSS receiver; the GNSS receiver uploads the obtained positioning data to a CORS data processing and controller center in real time and requests positioning differential data; the CORS data processing and control center sends requested positioning differential data to the GNSS receiver according to the positioning data and the positioning differential data request; the GNSS receiver corrects the positioning data according to the positioning differential data; the GNSS receiver sends the corrected positioning data circularly to the CORS data processing and control center so as to obtain higher-precision positioning differential data; and the GNSS receiver distributes corrected and precise positioning data. The method and system for improving the positioning accuracy of the navigation satellite can correct and eliminate common error terms in real time and effectively reduce the influence of correlated errors, so as to obtain more accurate positioning results and improve positioning accuracy.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and system for improving positioning accuracy of navigation satellites. Background technique [0002] Traditional satellite positioning technology has low positioning accuracy and limited application fields. With the development of satellite positioning technology, the positioning accuracy of GNSS products can reach centimeter level, and it has been widely used in many fields such as geodetic surveying, ship positioning, and vehicle positioning. application. Contents of the invention [0003] In view of the above-mentioned deficiencies in the current satellite position accuracy, the present invention provides a method and system for improving the positioning accuracy of navigation satellites, which can be corrected in real time, eliminate common error items, effectively weaken the influence of related errors, and obtain more accurate positioning results. Improv...
