Performance analysis of Real Time PPP for transit of Mercury

Measurement: Journal of the International Measurement Confederation, 2018
Abstract In recent years, Precise Point Positioning (PPP) techniques, which are alternative to relative positioning techniques, have begun to be widely used in Global Navigation Satellite System (GNSS) positioning applications. The PPP technique offers an effective solution to obtain coordinates at high accuracy with a single receiver. Real-time PPP (

A New Method for Real-Time PPP Correction Updates

2016
Real-time Precise Point Positioning (PPP) is expected to find more and more applications with various precise satellite orbit and clock products becoming more easily and reliably available. A crucial aspect for current real-time PPP system is the transmission of precise satellite orbit and clock correction data to the PPP users at a high update rate ...

Instantaneous Cycle-Slip Correction for Real-Time PPP Applications

Navigation, 2010
Real-time precise point positioning (PPP) is limited to only a few applications using a moving receiver because the quality of the solution is vulnerable to interruptions in signal tracking. A loss of lock on all GPS signals simultaneously implies that users may have to wait for several minutes before again obtaining cm-level precision. To avoid such a
