Gnss multipathing
WebMultipath is not modeled in GNSS data processing usually; it can lead to errors of few meters in pseudorange measurements and few centimeters in carrier-phase measurements. Therefore, multipath errors may limit the standard positioning service to few meters and high-precision positioning to few centimeters. This chapter describes the multipath ...
