Over the past five years, the International GNSS Service (IGS) has made continuous efforts
to extend its service from GPS and GLONASS to the variety of newly established global and …

At present, reliable ambiguity resolution in real-time GPS precise point positioning (PPP)
can only be achieved after an initial observation period of a few tens of minutes. In this study …

The demand for high-precision positioning has risen substantially in modern urban settings.
In that regard, Global Navigation Satellite Systems (GNSS) offer several advantages such as …

The concept of single-frequency, dual-system (SF-DS) real-time kinematic (RTK) positioning
has become feasible since, for instance, the Chinese BeiDou Navigation Satellite System …

In spite of significant research in the development of efficient algorithms for three carrier
