AN EXPERIMENTAL INVESTIGATION OF RELATIVISTIC EFFECTS IN GPS

Abstract: Relativistic corrections have been implemented for the GPS satellites to account for time dilation and difference in gravitational potential for satellite clocks with respect to clocks on the earth. No similar corrections are known to be made for GPS receivers on dynamic platforms. This paper presents an investigation into the relativistic effects proposed in [I/. It is shown that two of the three terms affecting the receiver clock proposed in [ll are satellite dependent, a result that is not borne out by experimental data. This finding supports the conclusion in [2] that there are no differences among the earth- centered, earth-fisted (ECEF), earth-centered inertial (ECI,,, and topocentric reference frames as long as the appropriate transformations are applied.
