METHOD AND SYSTEM FOR PREVENTING LEAKAGE OF BEIDOU DIFFERENTIAL POSITIONING DATA

摘要

A method and system for preventing leakage of Beidou differential positioning data. The method comprises the following steps: step 1, determining the number of positioning terminals (5); step 2, making identification cards (4), one identification card (4) corresponding to one positioning terminal (5), and writing data into each identification card (4); step 3, putting the identification cards (4) into the slots of the positioning terminals (5) corresponding thereto; step 4, verifying whether read data is accurate; and step 5, generating Beidou differential positioning data by means of a positioning base station (2), a positioning satellite (1), and the normally running positioning terminal (5). The system for preventing leakage of Beidou differential positioning data comprises a positioning base station (2), a positioning satellite (1), a service terminal (3), a card issuing device, multiple identification cards (4), and multiple positioning terminals (5). By effectively separating an installer from configuration information, leakage of the configuration information caused by intention or fault of the installer is avoided, thereby effectively protecting the security of positioning data, and avoiding leakage of Beidou differential positioning data.
