Abstract
A Global Positioning System (GPS) receiver includes a GPS receiving unit configured to receive navigation data from at least one visible satellite, a decoder configured to decode the received navigation data to extract time and almanac information from the decoded navigation data and a database configured to store satellite disposition information. A satellite location determining unit is configured to select at least one visible satellite candidate using the time information and the satellite disposition information, and to determine locations-in-space of the at least one visible satellite candidate with the almanac information. Also, a navigation filter is configured to calculate pseudo-ranges from the at least one visible satellite and the selected at least one visible satellite candidate using the corresponding locations-in-space, and to determine a location of the GPS receiver using the calculated pseudo-ranges.
