Abstract
Methods and apparatus are provided for estimating position location of a mobile device.
Claims67
A method comprising:
- with a mobile device:
- estimating an across-pathway position location of said mobile device by comparing an expected satellite positioning system (SPS) satellite reception pattern and an observed SPS satellite reception pattern, and
- estimating an along-pathway position location of said mobile device based, at least in part, on at least one SPS signal acquired from at least one satellite, wherein said at least one SPS signal is received line-of-sight (LOS) by said mobile device.
A method comprising:
- with a mobile device:
- estimating an across-pathway position location of said mobile device by comparing an expected satellite positioning system (SPS) satellite reception pattern and an observed SPS satellite reception pattern, and
- establishing said observed SPS satellite reception pattern based, at least in part, on SPS signal reception determination of a LOS/NLOS detector within said mobile device.
An apparatus for use in a mobile device, the apparatus comprising:
- means for estimating an across-pathway position location of said mobile device by comparing an expected satellite positioning system (SPS) satellite reception pattern and an observed SPS satellite reception pattern;
- and
- means for estimating an along-pathway position location of said mobile device based, at least in part, on at least one SPS signal acquired from at least one satellite, wherein said at least one SPS signal is received line-of-sight (LOS) by said mobile device.
An apparatus for use in a mobile device, the apparatus comprising:

- and
- means for establishing said observed SPS satellite reception pattern based, at least in part, on SPS signal reception determination of a LOS/NLOS detector within said mobile device.
A mobile device comprising:
- a satellite positioning signal (SPS) receiver;
- and
- a processing unit to:
- estimate an across-pathway position location of said mobile device by comparing an expected SPS satellite reception pattern and an observed SPS satellite reception pattern;
- and
- estimate an along-pathway position location of said mobile device based, at least in part, on at least one SPS signal acquired from at least one satellite, wherein said at least one SPS signal is received line-of-sight (LOS) by said SPS receiver.
