With the widespread use of high sensitivity receivers the presence of multipath has taken on
a new significance. GPS receivers optimized for indoor signal levels are easily able to detect …

Starting with the narrow correlator in 1992, the development of GPS signal processing
techniques to reduce pseudorange and phase measurement errors due to multipath have …

Proposed changes in the civil and military GPS signal structures offer the possibility of
improved in-receiver multipath mitigation in high-performance differential positioning …

There have been a number of important developments in recent years in the mitigation of
code multipath in GPS receivers but very little progress has been made with the mitigation of …

Multipath is the most prominent error source in a properly designed receiver and numerous
techniques and approaches have been used and proposed for detection, characterization …

A method has been previously proposed for minimizing the impact of multipath on accuracy
of the GPS Local Area Augmentation System (LAAS) by averaging measurements from …

Many multi-path mitigation schemes have been described in the literature for application to
GPS ranging performance. Most of these are assumed to operate in conditions with high …

Multipath is the phenomenon where a signal arrives at an antenna via several paths due to
signal reflection and diffraction. These paths are superimposed on the direct signal at the …

In a GPS receiver, multipath causes an error in the meas-urement of the pseudorange
because it affects the delay-lock tracking loop, which functions to equalize the corre-lation …

This paper introduces the design of a modijied Phase-Lock Loop (PLL) for carrier tracking
and a Delay-Locked Loop (DLL) for code tracking for multipath efiects, mitigation in the GPS …
