  • Method and system for power optimization for a global navigation satellite system
    Patent number: 9494692
    Abstract: Methods and systems for power optimization of a global navigation satellite system may comprise receiving LEO RF satellite signals utilizing a LEO satellite signal receiver path (LEO Rx) in a wireless communication device (WCD). Circuitry in the LEO Rx may be configured in a powered down state based on a sleep schedule. A location of the wireless communication device may be determined utilizing LEO signals received by the LEO Rx. The sleep schedule may be based on a desired accuracy of the determined location, the relative strengths of signals received from a plurality of LEO satellites, a relevance factor generated by a position engine and communicated to the sort module, or a desired power level of the WCD. The relative strengths of received signals may be compared utilizing a sort module in a LEO demodulator in the LEO satellite signal receiver path.
