Compared analysis of the reflection an diffraction effects of GPS signals on the pesudo-range determination in receivers

Key Points

Reflection effects from surfaces significantly influence GPS signal accuracy, while diffraction plays a lesser role.
The Fresnel-Kirchoff integral calculates reflection metrics, showing a superior impact compared to diffraction.
Experiments confirm theoretical predictions about the dominance of reflection effects on GPS performance.
The results indicate potential improvements in GPS signal processing techniques, especially for localized areas.

Abstract

This paper describes the effects of GPS signals reflection on finite surfaces and diffraction on straight borders. These effects have been evaluated theoretically and verified experimentally. The reflection has been calculated using the Fresnel-Kirchoff integral and the diffraction with the Keller GTD theory. The conclusion emphasize the greater importance of effect of "reflection" compared to those of "diffraction", much more localized and of lower amplitude
