Abstract
A global navigation satellite system (GNSS) enabled device that is configured to distinguish reflected GNSS signals from direct GNSS signals utilizing three-dimensional models of the terrain in the proximity of the GNSS enabled device. By utilizing the identification of reflected GNSS signals, the reflected GNSS signals can be excluded and/or weighted to achieve a more accurate location determination.
