Abstract
Techniques provided herein are directed toward using a camera, such as a forward-facing camera, to identify non-line-of-sight (NLoS) satellites in a satellite positioning system. In particular, successive images captured by the camera of the vehicle can be used to create a three-dimensional (3-D) skyline model of one or more objects that may be obstructing the view of a satellite (from the perspective of the vehicle). Accordingly, this allows for the determination of NLoS satellites and exclusion of data from the NLoS satellites in the determination of the location of the vehicle. Techniques may further include providing the determined location of the vehicle.
