Precise Point Positioning on the Reliable Detection of Tropospheric Model Errors. [PDF]
Sensors (Basel), 2020 Precise point positioning (PPP) is one of the well-known applications of Global Navigation Satellite System (GNSS) and provides precise positioning solutions using accurate satellite orbit and clock products. The tropospheric delay due to the neutral atmosphere for microwave signals is one of the main sources of measurement error in PPP.

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.
