Abstract
Multipath is one of the main error sources in global navigation satellite system(GNSS) positioning. The high-resolution corrector (HRC) is a multipath mitigation technique well known for its outstanding performance for middelayed multipath, but still has a remaining error for the short-delayed multipath. This paper proposes a modified HRC scheme that can remove or reduce the error for short-delayed multipath signals. It estimates the HRC tracking error and augments the conventional HRC with the estimates. The method was implemented with a software receiver and the test results show short-delayed multipath-induced error were reduced to about one third of those from the conventional HRC.
