  • Satellite positioning system receivers and methods
    Patent number: 7969356
    Abstract: A satellite positioning system receiver programmed to determine information for a satellite using ephemeris data (710), determine information for the same satellite using almanac data (722), which may have been previously stored on the receiver, to determine an error between the satellite information determined from the ephemeris data and the satellite information determined from the stored almanac data (730), and to update the stored almanac data based upon the error (734).
    Type: Grant
    Filed: September 13, 2005
    Date of Patent: June 28, 2011
    Assignee: Motorola Mobility, Inc.
    Inventors: Thomas M. King, George J. Geier, Mark Heng, Robert Harbour
  • Satellite positioning system receivers and methods
    Patent number: 7336224
    Abstract: A satellite positioning system receiver having a battery, wherein the receiver is programmed to determine (310) whether the receiver is connected to a power supply other than its battery, to begin continuous reception (320) of satellite positioning system navigation data when the receiver is connected to a power supply other than its battery, and to store (330) the navigation data received in memory of the receiver.

  • Satellite positioning system receivers and methods
    Patent number: 7298321
    Abstract: A satellite positioning system receiver programmed to operate synchronously with an expected time of arrival of information from at least one satellite of a satellite positioning system, and to receive the information from the at least one satellite when the receiver is operating during the expected time of arrival of the information. In one embodiment, the receiver operates synchronously with an expected arrival of specific subframe information from at least one satellite of a satellite positioning system, and receives the specific subframe information when the receiver is operating.
