The aim of this session is to advertise advances and prospects in GNSS techniques and applications with a special focus on Precise Point Positioning (PPP). PPP is becoming a major technique in the field of sciences research activities. This is mainly due to the continuous improvement in terms of performance and availability of IGS products like orbits, clocks, and EOPs both for post-processing and real-time scenarios. In addition the development of new processing strategies and the availability of new GNSS signals is making PPP a serious alternative to the classical differential approaches like RTK or Double-Differencing. We encourage submissions on any scientific topic involving GNSS PPP technique including real time, static, kinematic, high frequency, multi-GNSS positioning or timing applications. Presentations dealing with related technical issues like convergence time, ambiguity fixing, errors analysis, time series filtering, etc. are also welcome.
