Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] see figure 1 , which is a flow chart of an embodiment of a method for securely converting satellite positioning coordinates according to the present invention.

[0033] A method for secure conversion of satellite positioning coordinates, characterized in that it comprises the steps of:

[0034] S101: Obtain location information uploaded by a user terminal, where the location information includes location coordinates and a user identification code;

[0035] After the user terminal is turned on, it will continuously upload location information. The location information includes location coordinates and user identification codes. The location coordinates may be positioning coordinates obtained under the Global Positioning System (GNSS), and the user identifi...

Abstract

The invention discloses a satellite positioning coordinate confidentiality conversion method and system. The method includes the step of obtaining position information uploaded by a user terminal, wherein the position information comprises position coordinates and user identification codes, the step of querying and obtaining practical conversion parameters from a database according to the user identification codes and obtaining terminal pseudo-conversion parameters corresponding to the user identification codes, the step of converting the terminal pseudo-conversion parameters and the practical conversion parameters into second pseudo-conversion parameters through a preset conversion model and carrying out coordinate conversion on the position coordinates by using the second pseudo-conversion parameters to generate virtual coordinates, and the step of sending the virtual coordinates and the terminal pseudo-conversion parameters to the user terminal for coordinate conversion so that local coordinates can be obtained. The practical conversion parameters are not involved in the coordinate conversion process, even if the practical conversion parameters are illegally captured and decoded, only the terminal pseudo-conversion parameters, rather than the practical conversion parameters, can be obtained, the practical conversion parameters are prevented from being illegally captured, and security and confidentiality of the practical conversion parameters are guaranteed.

Description

【Technical field】 [0001] The invention relates to wireless positioning technology and security technology, in particular to a satellite positioning coordinate security conversion method and system. 【Background technique】 [0002] With the integrated application of computer technology, communication technology, GNSS (Global Navigation Satellite System, Global Navigation Satellite System) positioning technology, etc., the establishment of CORS (Continuous Operational Reference System, continuous operation satellite positioning service integrated system) can realize long-distance conditions. High-precision, high-reliability real-time positioning, so it has been widely promoted and used in our country. Since the positioning coordinates of GNSS are usually calibrated under the WGS84 (World Geodetic System 1984, World Surveying System 1984) system, and in China, the local coordinate system is usually used to mark the positioning coordinates, so when using the global positioning sy...
