Reduction of Precise Point Positioning Convergence Period

Precise Point Positioning (PPP) has become a popular technique to process GNSS receiver data by applying precise satellite orbit and clock information, along with other minor corrections. Although PPP presents definite advantages such as operational …

Reduction of PPP convergence period through pseudorange multipath and noise mitigation

Pseudorange multipath and pseudorange noise are the largest remaining unmanaged error sources in PPP. It is proposed that by reducing the effects of multipath and noise on the pseudorange observable, accurate estimates of carrier phase float …
