A Global Navigation Satellite System (GNSS) receiver receives band-limited composite signals corresponding to respective satellites in the GNSS. The composite signal is composed of a direct path signal and a multipath signal. For chip edge hopping of a pseudo-random code, the receiver obtains correlation samples (I (t) samples and Q (t) samples) of the composite signal and compares them with predetermined filter characteristics (SR (t) samples) corresponding to a filter for band-limiting the composite signal. Based on the comparison, the receiver determines a phase and / or a response time error of the chip edge hopping due to the multipath signal. The receiver adjusts a pseudo-range measurement for the respective satellite and / or adjusts a carrier phase measurement for the respective satellite in accordance with the determined and / or adjusted pseudo-range measurement for the respective satellite. The receiver performs a navigation function using the adjusted pseudo-range and / or carrier phase measurements for the respective satellites.
