ABSTRACT:
GPS position information is collected and stored in a computer system. The GPS position information includes time-stamps that indicates when the GPS position information was collected. The computer system uses the time stamps to generate an error correction file name for an error correction file that can be used to correct the GPS position information. Using the generated error correction file name, the computer system connects to a file server that stores differential GPS error correction files and copies the needed differential GPS error correction file. The computer system connects to the DGPS file server using the File Transfer Protocol of the global Internet. The computer system then corrects the GPS position information in the computer system using the retrieved DGPS error correction file.
