An uncombined triple-frequency user implementation of the decoupled clock model for PPP-AR [PDF]
Journal of Geodesy, 2021 AbstractPrecise point positioning (PPP) has proved its capacity to provide centimetre-level position solutions in open sky environments. However, the technique still suffers from relatively long initial convergence times. Research has proved the potential of ambiguity resolution (AR) to reduce the convergence time and three main methods are used to ...

Land deformation monitoring in mining area with PPP-AR
International Journal of Mining Science and Technology, 2014 Abstract The mining area deformation monitoring theory and method using precise point positioning (PPP) ambiguity resolution (AR) were studied, and an ambiguity fixing model with satellite and receiver combination phase delay (CPD) was proposed for zero-differenced PPP ambiguity fixing and its corresponding formula derivation was given.

Robust PPP-AR Using M-Estimators for Multi-Fault Scenarios [PDF]
2025 IEEE/ION Position, Location and Navigation Symposium (PLANS)Urban GNSS positioning is severely affected by multipath propagation and non-line-of-sight (NLOS) reception, which give rise to non-Gaussian measurement errors and multiple simultaneous outliers. These effects challenge conventional Precise Point Positioning with Ambiguity Resolution (PPP-AR) techniques, whose estimation performance degrades ...
