Method and apparatus for locating position of a mobile receiver is described. In one embodiment, satellite measurements are obtained at the mobile receiver for a plurality of satellites in a satellite positioning system constellation. Satellite trajectory data is obtained at the mobile receiver from a server. Ephemeris data is obtained at the mobile receiver from at least one satellite of the plurality of satellites. Position is computed for the mobile receiver using the satellite measurements, the satellite trajectory data, and the ephemeris data.
