Abstract:
A system for processing satellite position information, said system comprising:a communication medium; a first satellite positioning system (SPS) reference receiver having a first known position and having a first communication interface which is coupled to said communication medium, said first SPS reference receiver transmitting a first satellite ephemeris data into said communication medium; a second SPS reference receiver having a second known position and having a second communication interface which is coupled to said communication medium, said second SPS reference receiver transmitting a second satellite ephemeris data into said communication medium; and a first digital processing system coupled to said communication medium to receive at least one of said first satellite ephemeris data and said second satellite ephemeris data and to provide satellite information for a mobile SPS receiver in order to determine a navigation solution of a position information for said mobile SPS receiver wherein said mobile SPS receiver is coupled to a wireless cellular receiver which receives said satellite information and provides said satellite information to said mobile SPS receiver and wherein said mobile SPS receiver determines a position solution from pseudoranges determined by said mobile SPS receiver.
