DOI: 10.1007/s10291-017-0653-2

Abstract: Precise Point Positioning (PPP) is a popular Global Positioning System (GPS) processing strategy, thanks to its high precision without requiring additional GPS infrastructure. Single-Frequency PPP (SF-PPP) takes this one step further by no longer relying… read more here.

DOI: 10.1007/s10291-019-0891-6

Abstract: Ambiguity resolution in real-time kinematic (RTK) positioning is increasingly dependent on the combination of multi-GNSS observations, especially in challenging signal environments such as urban canyon areas. By applying a priori calibration to the receiver-dependent differential… read more here.

DOI: 10.1007/s10291-019-0895-2

Abstract: Deriving the ionospheric total electron content (TEC) from the global navigation satellite systems (GNSS) measurements typically assumes the receiver differential code biases (RDCBs) to remain unchanged within at least 1 day. However, the RDCBs sometimes… read more here.
