1. 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, andestimating 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.
