Abstract
Structures and techniques are disclosed that can be used to reduce or remove code multipath error in GNSS receivers by implementing one or more monitoring correlators in a multipath-error estimation and correction (MEC) module. The MEC module detects and provides for correction of correlation peak distortion. In exemplary embodiments, a code tracking loop integrates all-chip-edges of a PRN, and a narrow-correlator is used to update the tracking loop rate while a multipath estimation module implements a blanked correlator to estimate and remove the multipath bias from the code tracking loop measurements.
