Abstract
A technique of accurately determining the relative position between two points, in real-time, using a single GPS receiver that makes measurements of signals transmitted from GPS satellites. A technique is applied where differential correction terms are computed as a location at an instant of time, and then applied to further times, after applying atmospheric delay adjustments, so that the position of the GPS receiver is determined accurately relative to the position at the original instant of time.
