The present invention discloses a method and a device for avoiding Beidou differential location data leakage. The method comprises the following steps of: the step 1, determining the quantity of location terminals; the step 2, making identity recognition cards, and writing data into each identity recognition card, wherein each identity recognition card corresponds to one location terminal; the step 3, putting the identity recognition cards into slot of the corresponding location terminals; the step 4, verifying whether the read data is accurate; and the step 5, generating Beidou differential location data through a location base station, a location satellite and a normally operating location terminal. The system comprises a location base station, a location satellite, a service terminal, acard sending device, a plurality of identity recognition cards and a plurality of location terminals. The method and the device for avoiding Beidou differential location data leakage effectively separate installation personnel from configuration information to avoid configuration information leakage caused by the installation personnel's purpose or the installation personnel's faults, effectivelyprotect location data safety and avoid generation of the problem of the Beidou differential location data leakage.

Method and device for avoiding Beidou differential location data leakage

The invention provides an RTK resolving positioning system and method of a server, and belongs to the technical field of high-precision positioning. The system comprises flow stations, a reference station and a server; each flow station comprises an active antenna, a positioning module, an embedded processor and a communication module; and the server comprises a data distribution assembly, a resolving pool and a database. The method comprises that the data distribution assembly receives a configuration file and correction data from the reference station and converted observation information from the flow stations, the received data is forwarded to the corresponding resolving pool according to an ID of the flow station, and a positioning result returned from the resolving pool is sent to the corresponding flow station and database; and if the quality of a satellite signal is low, or connection with the reference station is lost, the server requests the flow station to upload NMEA information as a resolving result. The problems that a present flow station of RTK positioning technology is large in size and high in power consumption are solved. The system and method can be applied to RTK positioning technology.
