Abstract
The invention relates to a system and method for achieving GNSS receiver upgrading based on a secure USB disk. The system comprises the secure USB disk used for storing an upgrading program of a matched GNSS receiver and an ID chip used for storing an SN of the matched GNSS receiver, wherein the SN is cured in the ID chip during USB disk production. The method comprises the steps that the secure USB disk is connected with the GNSS receiver; the GNSS receiver reads the SN in the ID chip and judges whether the SN is matched with an SN of a local computer or not, if yes, the step continues to be conducted, an upgrading file is read from the secure USB disk for upgrading, and if not, the upgrading program is exited. By the adoption of the system and method for achieving GNSS receiver upgrading based on the secure USB disk of the structure, the efficiency of GNSS upgrading is greatly improved, manpower and material resources are saved, the upgrading security is greatly enhanced, and the application range is wider.
