This paper aims to present a new PPP technique for precision orbit determination (POD) and on-orbit navigation (NAV) of LEO satellites. A PPP filter was designed by modeling simple white noise processes for position deviation (from the pre-determined reference orbit) and receiver clock. The developed PPP software was assessed in terms of positioning accuracy by processing one-day GPS data collected with NASA/JPL's Blackjack receiver onboard the satellite CHAMP. The assessment showed that dual-frequency PPP in space is capable of producing NAV solution with 3-D positional accuracy of about one and half meters, and POD solution of less than one meter, both in the 2-sigma sense.
