Abstract

The invention provides a satellite positioning carrier phase difference method, which comprises the following steps of: acquiring the non-differential error correction number of the carrier phase observed value of each satellite of each reference station by utilizing the observed data of a reference station network; calculating to obtain the error correction number of the non-differential carrier phase observed value of each satellite at a user station according to the non-differential error correction number of the carrier phase observed value of each satellite at the selected reference station, wherein the non-differential error correction number of each satellite includes various observation error influences and ambiguity information of the carrier phase observed value; and carrying out the high-precision carrier phase positioning of the user station by utilizing the error correction number of the non-differential carrier phase observed value of each satellite at the user station.

Description

technical field

[0001] The invention relates to the field of computer applications, in particular to a carrier phase difference method for satellite positioning. Background technique

[0002] Network RTK (Real-Time Kinematic) is to deploy multiple (generally at least three) reference stations in a certain area to form a mesh coverage of the area, and use all or part of the reference station data to estimate the satellite positioning of the area or the user The error information generates differential information, and the real-time user receives the differential information and performs ambiguity processing and resolution of the carrier phase to obtain real-time high-precision three-dimensional position information of the user. It can provide users with centimeter-level real-time high-precision three-dimensional positions in a wide range. Compared with traditional RTK technology, network RTK has higher stability, availability and cost-effectiveness. Its biggest advantage is ...
