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

Precise Point Positioning for TAI computation [PDF]
2007 IEEE International Frequency Control Symposium Joint with the 21st European Frequency and Time Forum, 2007 We discuss the use of some new time transfer techniques for computing TAI time links. Precise point positioning (PPP) uses GPS dual frequency carrier phase and code measurements to compute the link between a local clock and a reference time scale with the precision of the carrier phase and the accuracy of the code.
