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.

A method of satellite-based determination of a position 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;
- identifying, based on an error not meeting or exceeding an error threshold, one or more of the plurality of second satellite measurements in the second frequency as qualified, the error being associated with (i) a first pseudorange determined based on the plurality of first satellite measurements and (ii) a second pseudorange determined based on the plurality of second satellite measurements;
- and
- based on a quantity of the qualified one or more second satellite measurements exceeding a threshold number of measurements, using at least the qualified one or more second satellite measurements to determine the position of the mobile device, sending at least the qualified one or more second satellite measurements to a network device, or disabling usage of the first satellite measurements in the first frequency or the second satellite measurements in the second frequency, wherein the threshold number of measurements is set based at least on a characteristic of an environment associated with the mobile device.
A mobile device comprising:
- one or more Global Navigation Satellite System (GNSS) receivers;
- one or more memory;
- and
- one or more processors communicatively coupled to the one or more GNSS receivers and the one or more memory, and configured to:
- obtain a plurality of first satellite measurements in a first frequency, and a plurality of second satellite measurements in a second frequency;
- identify, based on an error not meeting or exceeding an error threshold, one or more of the plurality of second satellite measurements in the second frequency as qualified, the error being associated with (i) a first pseudorange determined based on the plurality of first satellite measurements and (ii) a second pseudorange determined based on the plurality of second satellite measurements;
- and
- based on a quantity of the qualified one or more second satellite measurements exceeding a threshold number of measurements, use at least the qualified one or more second satellite measurements to determine a position of the mobile device, send at least the qualified one or more second satellite measurements to a network device, or disable usage of the first satellite measurements in the first frequency or the second satellite measurements in the second frequency, wherein the threshold number of measurements is set based at least on a characteristic of an environment associated with the mobile device.
An 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 identifying, based on an error not meeting or exceeding an error threshold, one or more of the plurality of second satellite measurements in the second frequency as qualified, the error being associated with (i) a first pseudorange determined based on the plurality of first satellite measurements and (ii) a second pseudorange determined based on the plurality of second satellite measurements;
- and
- means for, based on a quantity of the qualified one or more second satellite measurements exceeding a threshold number of measurements, using at least the qualified one or more second satellite measurements to determine a position of the apparatus, sending at least the qualified one or more second satellite measurements to a network device, or disabling usage of the first satellite measurements in the first frequency or the second satellite measurements in the second frequency, wherein the threshold number of measurements is set based at least on a characteristic of an environment associated with the mobile device.
A non-transitory computer-readable apparatus comprising a storage medium, the storage medium comprising a plurality of instructions configured to, when executed by one or more processors, cause a mobile device to:
- obtain a plurality of first satellite measurements in a first frequency, and a plurality of second satellite measurements in a second frequency;
- identify, based on an error not meeting or exceeding an error threshold, one or more of the plurality of second satellite measurements in the second frequency as qualified, the error being associated with (i) a first pseudorange determined based on the plurality of first satellite measurements and (ii) a second pseudorange determined based on the plurality of second satellite measurements;
- and
- based on a quantity of the qualified one or more second satellite measurements exceeding a threshold number of measurements, use at least the qualified one or more second satellite measurements to determine a position of the mobile device, send at least the qualified one or more second satellite measurements to a network device, or disable usage of the first satellite measurements in the first frequency or the second satellite measurements in the second frequency, wherein the threshold number of measurements is set based at least on a characteristic of an environment associated with the mobile device.
