Problems solved by technology

[0003] However, the existing network RTK technology only sends a single virtual reference station data to the rover user. When the virtual reference station data cannot be updated in time, the positioning accuracy and reliability of the corresponding rover user will gradually decrease over time; when the virtual reference station When the data quality of the station data is poor, it may cause the positioning error of the user of the rover station; in addition, with the movement of the user of the rover station, when the main base station closest to the rover station changes, the user of the rover station will be re-initialized, and the user cannot Obtain high-precision positioning results

Abstract

An embodiment of the invention discloses a carrier phase differential positioning method, a carrier phase differential positioning device, electronic equipment and a storage medium. By sending differential data of one or more virtual reference station to a moving station user, even if the differential data of part of the virtual reference stations cannot be updated in time or the quality is poor,the moving station user can further use the differential data of other virtual reference stations to carry out carrier phase differential positioning, and the positioning precision and reliability arenot reduced; meanwhile, when the mobile station user moves from one reference station coverage area to another reference station coverage area, the mobile station user does not need to be initializedagain, and a continuous high-precision positioning result can be obtained.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a carrier phase differential positioning method, device, electronic equipment, and storage medium. Background technique [0002] Network RTK (Real-Time Kinematic, real-time dynamic) is a kind of GNSS (Global Navigation Satellite System, Global Navigation Satellite System) positioning technology. Using this technology, real-time centimeter-level positioning accuracy can be obtained, and it has fast initialization speed and high positioning accuracy. It is widely used in transportation, surveying and mapping, construction and other fields. [0003] However, the existing network RTK technology only sends a single virtual reference station data to the rover user. When the virtual reference station data cannot be updated in time, the positioning accuracy and reliability of the corresponding rover user will gradually decrease over time; when the virtu...
