Existing USB flash disk technology is quite ripe, it is only necessary to an ID chip is added in USB flash disk, is had in chip supporting
No. SN of receiver, the ROMPaq in insertion USB flash disk every time inside receiver can read USB flash disk SN, if without No. SN, or
Person and No. SN mismatch of machine, just do not perform ensuing ROMPaq.Memory space inside receiver is divided into, boot
Area, kernel areas, file system area, ROMPaq can search for file corresponding to each area from USB flash disk, find respective file, just
Corresponding area can be upgraded using directly erasable mode, accomplish the flexible upgrading of substep.
The realization of the present invention needs one and the supporting safe U disc of machine, it is only necessary to an ID chip is added in USB flash disk
(see Fig. 2), there be No. SN of companion receiver in chip.The flow chart of whole escalation process is shown in Fig. 1.In insertion USB flash disk every time
ROMPaq inside receiver can read USB flash disk SN, if without No. SN, or No. SN mismatch with machine, just do not hold
The ensuing ROMPaq of row.Memory space inside receiver is divided into, and boot areas, kernel areas, file system area is (see figure
3), ROMPaq can search for file corresponding to each area from USB flash disk, find respective file, will utilize directly erasable mode
Corresponding area is upgraded, has accomplished the flexible upgrading of substep.
To achieve these goals, it is of the invention to realize that the system of GNSS receiver upgrading includes safe U based on safe U disc
Disk, for described safe U disc to store the ROMPaq of supporting GNSS receiver, described safe U disc includes an ID chips, institute
