Precise point positioning with multipath estimation [PDF]
2016 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2016 Precise Point Positioning with low-cost GNSS receivers is attractive for numerous applications, as it can provide centimeter-level positioning without the exchange of raw measurements from a reference station. However, pseudorange multipath has to be accurately considered for a reliable ambiguity fixing. In this paper, we derive a precise model for the
