Differential delay between two geodetic gps receivers for L1 and L2 code and carrier signals

Abstract

Differential delay measurements of two Global Positioning System satellite signal receivers of different manufacture were measured without using geodetic processing software. The two receivers were connected to the same antenna through a splitter, and driven by the same clocks. We obtained the continuous averages of differential delays through the receivers over a period of 128 days. This report will describe the process by which we calculated these averages and will also present the results found for each of the four signal types studied, which are the L1 and L2 carrier phases, and the C1 and P2 code phases.
