Abstract
Methods and apparatus are provided for estimating position location of a mobile device.
Claims28
A method comprising, at a mobile device:
- obtaining three-dimensional geographic information identifying at least one open area and at least a height associated with at least one object adjacent to the at least one open area;
- determining at least one pathway in said open area;
- determining expected line of sight and expected non-line of sight detections of satellite positioning system (SPS) signals at locations along said pathway based, at least in part, on said three dimensional geographic information;
- acquiring one or more signals at a receiver;
- and
- estimating a location of said mobile device based, at least in part, on application of said expected line of sight detections and expected said non-line of sight detections to said acquired signals.
3 more elements
A mobile device comprising:
- a receiver;
- and
- at least one processing unit operatively coupled to said memory and enabled to
- obtain three-dimensional geographic information identifying at least one open area and at least a height associated with at least one object adjacent to the at least one open area;
- determine at least one pathway in said open area;
- determine expected line of sight and expected non-line of sight detections of satellite positioning system (SPS) signals at locations along said pathway based, at least in part, on said three dimensional geographic information;
- and
- estimate a location of said mobile device based, at least in part, on application of said expected line of sight detections and expected said non-line of sight detections to signals acquired at said receiver.

An article comprising a computer readable medium having computer implementable instructions stored thereon which if implemented by one or more processing units operatively enables the one or more processing units to:
- obtain three-dimensional geographic information identifying at least one open area and at least a height associated with at least one object adjacent to the at least one open area;
- determine at least one pathway in said open area;
- determine expected line of sight and expected non-line of sight detections of satellite positioning system (SPS) signals at locations along said pathway based, at least in part, on said three dimensional geographic information;
- and
- estimate a location of said mobile device based, at least in part, on application of said expected line of sight detections and expected said non-line of sight detections to signals acquired at a receiver.
