Multipath Errors Induced by Electronic Components in Receiver Hardware

James P. Keith

Abstract:	Multipath errors in a GPS position solution are introduced when a signal from an orbiting satellite takes multiple paths to the receiver. The magnitude of this error is dependent upon several factors including the delay of the reflected signal, the strength of the reflected signal as well as the correlation technique implemented in the GPS receiver. Impedance mismatches between electronic devices can cause reflections of the input signal within GPS receivers. These reflections in turn can cause multipath errors in the position solution. The magnitude of the multipath error is a function of the magnitude and delay of the reflected signal as well as the frequency difference between the input signals.
