Ephemeris determination using intersatellite ranging and ephemeris knowledge of other satellites

The present invention provides a system (200) for determining the ephemeris of a space vehicle based on distances to and ephemeris of other spacecraft. An ephemeris determining subsystem (300) obtains ephemeris data (308) for one or more reference spacecraft. Distance information (306) is obtained b...
