  • GNSS navigation aided by static data
    Patent number: 8593347
    Abstract: A GNSS receiver includes a RF front end for receiving GNSS ranging signals, a navigation processor for calculating location from the ranging signals, and a repository of static data. The navigation processor includes the static data in the location calculation. Examples of static data include a digital elevation map, coordinates of tunnel entrances for use when the receiver resumes reception of the signals upon exiting a tunnel, and descriptions of structures in sufficient detail to enable multipath mitigation.

  • Method and apparatus for obtaining satellite trajectory data at a satellite positioning system receiver
    Patent number: 7342533
    Abstract: 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.
