Abstract:
A method and system for providing a user with correction information for use in accurately determining the location of the user. A plurality of monitor stations are disposed at a plurality of known fixed locations for monitoring a plurality of navigation data messages transmitted by Global Positioning Systems (GPS) Space Vehicles (SVs) and for determining a plurality of corresponding correction factors. A central ground station is operatively coupled to each of the plurality of monitor stations for receiving the plurality of correction factors from each of the plurality of monitor stations. A GPS transceiver receives at least one of the plurality of navigation data messages at an unknown location and determines a general location of the user. The general location of the user is then transmitted to the central ground station. The central ground station determines user location correction data based on the navigation data received by the user and the plurality of correction factors transmitted by each of the plurality of monitor stations.
