Problems solved by technology

When the network RTK provides precise positioning services for the rover, it first needs to generate differential corrections based on the rough coordinates sent by the rover to the central solution software, and then the central solution software sends the corresponding differential corrections to the rover. However, the rover The approximate coordinates of the station and the corresponding differential corrections are transmitted through the cellular network, and there is a risk of data tampering or leakage
Therefore, the reliability of the existing network RTK data transmission needs to be improved

Abstract

The invention provides a safe transmission method, device and system of network RTK data, and relates to the technical field of network RTKs, the method is applied to central calculation software of anetwork RTK, and the method comprises the following steps: firstly, receiving an encryption general coordinate sent by a mobile station of the network RTK, wherein the encryption general coordinate is obtained by encrypting the general coordinate of the moving station of the network RTK by using a public key of a differential correction number of a central point of a grid where the moving stationof the network RTK is located; obtaining a private key of a difference correction number of a central point of a grid where the moving station is located; and decrypting the encrypted general coordinate by using the obtained private key to obtain the general coordinate of the moving station. According to the invention, the reliability of network RTK data transmission is improved.

Description

technical field [0001] The invention relates to the technical field of network RTK, in particular to a method, device and system for secure transmission of network RTK data. Background technique [0002] Network RTK usually needs to establish multiple (generally three or more) base stations in an area to form a mesh coverage for the area, so as to provide high-precision positioning services for the rover in the area. When the network RTK provides precise positioning services for the rover, it first needs to generate differential corrections based on the rough coordinates sent by the rover to the central solution software, and then the central solution software sends the corresponding differential corrections to the rover. However, the rover The approximate coordinates of the station and the corresponding differential corrections are transmitted through the cellular network, and there is a risk of data tampering or leakage. Therefore, the reliability of the existing network ...
