Estimation of geographical coordinates using a differential GPS for short occupation times

Abstract

A short baseline consisting of two stations was measured three times during a three-day period March 21-23 to determine the precision of the vertical component using a differential Global Positioning System. Occupation times ranged from 270 to 600 minutes (4 to 10 hours). The power equation that best fits the regression for the vertical component is given by y=0.6397t-2.009, where y is the error in meters and t is time in minutes.
