  • Providing ephemeris data and clock corrections to a satellite navigation system receiver
    Patent number: 8207890
    Abstract: A device can access scaled values and scaling factors, which are used to convert the scaled values into coefficients and residuals. The coefficients and residuals can in turn be used with time-dependent functions to reconstruct predicted ephemeris data, including clock correction data, for satellite navigation system satellites. Ephemeris data that is broadcast from any of the satellites can be used to update the calculated ephemeris data.
    Type: Grant
    Filed: October 8, 2008
    Date of Patent: June 26, 2012
    Assignee: Qualcomm Atheros, Inc.
    Inventors: Sai Venkatraman, Janne Jarpenvaa, Qinfang Sun
  • System and method for determining position using doppler velocities
    Patent number: 8125378
    Abstract: This disclosure is directed to systems and methods for providing GPS positioning determinations from a single set of Doppler measurements from a plurality of satellites in conjunction with satellite ephemeris data and a rough GPS time estimate. Measured Doppler velocities are compared with Doppler velocities calculated from ephemeris data and used to estimate the receiver position.
