Precise point positioning with multipath estimation [PDF]

open access: yes2016 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 on the Reliable Detection of Tropospheric Model Errors. [PDF]

open access: yesSensors (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.
