Abstract

A dynamic gridded network RTK positioning method, system, terminal and storage medium suitable for a confidential environment provided by the present application, the method includes: inputting base station coordinates, base station real-time observation data basic geographic information data into the network RTK algorithm , a virtual user is set near each reference station, and VRS service data is generated for the virtual user; the generated VRS service data and virtual user coordinates are used as basic geographic information data after decryption, and are output in one direction from a confidential environment, As the input data of the dynamic gridded network RTK algorithm in a non-confidential environment, it participates in the production of network RTK service data; this application can guarantee the confidentiality requirements of the basic geographic information data, and realize the one-way data transmission and one-way data transmission of the dynamic gridded network RTK algorithm. Request for confidentiality of correspondence.

Description

technical field [0001] The present application relates to the technical field of RTK algorithm positioning, in particular to a dynamic gridded network RTK positioning method, system, terminal and storage medium suitable for a confidential environment. Background technique [0002] Network RTK technology usually provides service data for users in three technical ways: Trimble's virtual reference station technology (VRS), GEO++'s field correction parameter method (FKP), and Leica's master-auxiliary station technology (MAX). Among them, VRS technology uses two-way communication to request service data from the server, and FKP technology and MAX technology use broadcasting to broadcast service data to users. [0003] When the network RTK technology adopts VRS technology on the server side, after the user terminal receives the service data, the VRS data and the receiver observation data form a short baseline, and the network RTK will degenerate into a conventional RTK technology....
