Abstract
Techniques and apparatus for satellite-based determination of a position of a mobile device are disclosed. In some embodiments, such techniques include: obtaining a plurality of first satellite measurements in a first frequency, and a plurality of second satellite measurements in a second frequency; using at least qualified or consistent satellite measurements to determine the position of the mobile device, sending at least the qualified or consistent satellite measurements to a network device, or disabling usage of first satellite measurements in the first frequency or second satellite measurements in the second frequency.
Claims20
A method for enhanced operation of a mobile device, the method comprising:
- obtaining a plurality of first satellite measurements in a first frequency, and a plurality of second satellite measurements in a second frequency;
- determining at least one of (i) a consistency between the plurality of first satellite measurements and the plurality of second satellite measurements, or (ii) a consistency between a first position fix determined using the plurality of first satellite measurements and a second position fix determined using the plurality of second satellite measurements;
- determining signal strength characteristics associated with the plurality of first satellite measurements and the plurality of second satellite measurements;
- and
- based on the consistency determination and the signal strength determination, switching to a reduced-power mode by selectively disabling global navigation satellite system (GNSS) hardware configured to receive satellite measurements in the first frequency or the second frequency.
An apparatus for enhanced operation of a mobile device, comprising:
- a global navigation satellite system (GNSS) receiver that includes at least one receiver antenna;
- a memory;
- and
- one or more processors communicatively coupled with the GNSS receiver and the memory, wherein the one or more processors are configured to:
- obtain a plurality of first satellite measurements in a first frequency, and a plurality of second satellite measurements in a second frequency;
- determine at least one of (i) a consistency between the plurality of first satellite measurements and the plurality of second satellite measurements, or (ii) a consistency between a first position fix determined using the plurality of first satellite measurements and a second position fix determined using the plurality of second satellite measurements;
- determine signal strength characteristics associated with the plurality of first satellite measurements and the plurality of second satellite measurements;
- and
- based on the consistency determination and the signal strength determination, switch to a reduced-power mode by selectively disabling global navigation satellite system (GNSS) hardware configured to receive satellite measurements in the first frequency or the second frequency.
An apparatus for enhanced operation of a mobile device, the apparatus comprising:
- means for obtaining a plurality of first satellite measurements in a first frequency, and a plurality of second satellite measurements in a second frequency;
- means for determining at least one of (i) a consistency between the plurality of first satellite measurements and the plurality of second satellite measurements, or (ii) a consistency between a first position fix determined using the plurality of first satellite measurements and a second position fix determined using the plurality of second satellite measurements;
- means for determining signal strength characteristics associated with the plurality of first satellite measurements and the plurality of second satellite measurements;
- and
- means for switching, based on the consistency determination and the signal strength determination, to a reduced-power mode by selectively disabling global navigation satellite system (GNSS) hardware configured to receive satellite measurements in the first frequency or the second frequency.
