Abstract

A cloud RTK positioning method, disclosed by the present invention, comprises the steps of selecting the fixed reference stations, setting the standard coordinate positions, obtaining the observation data and sending to a cloud positioning calculation center; using the moving stations to obtain the observation data and send to the cloud positioning calculation center; using the cloud positioning calculation center to obtain the coarse positioning results of the moving stations, and selecting a reference station, positioning and calculating to obtain the precise positioning results of the moving stations and send to the moving stations. The present invention also discloses a system of applying the cloud positioning method to position. The system comprises the cloud positioning calculation center, a plurality of fixed reference stations, a plurality of moving stations and links for the data interaction among the cloud positioning calculation center, the fixed reference stations and the moving stations. According to the present invention, the large-scale positioning calculation is realized, the large-scale centralized CORS network construction is not needed, the network robustness is strong, and the positioning method and the positioning system are very beneficial to the large-scale application of the high-precision positioning navigation.

Description

technical field [0001] The invention specifically relates to a cloud RTK positioning method and system. Background technique [0002] RTK (Real Time Kinematic) technology is a real-time dynamic positioning technology based on carrier phase difference. It is based on real-time processing of carrier phase observations of two stations, and provides 3D positioning results in the specified coordinate system. The real-time positioning accuracy can reach the centimeter level, and has the advantages of good real-time performance and fast speed. The basic principle of RTK is that the reference station and the rover receive satellite signals at the same time, and the reference station transmits the observation data (mainly carrier phase, pseudo-range) and the standard coordinate position of the reference station to the rover through a data link (modem, radio or communication network). Station, the mobile station uses software to reduce the observation error of the mobile station thro...
