Abstract: The present disclosure discloses a method and a system for preventing leakage of Beidou differential positioning data. The method includes the following steps: step 1, determining the number of positioning terminals; step 2, making identification cards, wherein one identification card corresponds to one positioning terminal, and writing data into each identification card; step 3, putting the identification cards into the card slots of the positioning terminals corresponding to the identification cards; step 4, verifying whether the read data is accurate; step 5, generating the Beidou differential positioning data by the positioning base station, a positioning satellite and the positioning terminals operating normally. The system includes a positioning base station, a positioning satellite, a service terminal, a card issuing device, a plurality of identification cards and a plurality of positioning terminals.
