The continuous improvement of Global Navigation Satellite Systems (GNSS) in terms of performances, availability, modernisation and hybridizing makes them a more and more powerful technique. The ongoing development of dense Real Time (RT) GNSS station networks and the accompanying increase of accuracy and temporal resolution of derived products offers new opportunities to monitor geophysical processes at or close to the Earth's surface.

This session welcomes presentations dealing with analyzing GNSS phase data in real-time, and current applications that utilize the resulting observation streams (e.g GPS station position, tropospheric water content, ionosphere electron TEC, Earthquake early warning, Reflectometry, Time transfer,…). We particularly encourage also presentations concerning the quality of used RT satellite orbit and clock products (e.g. IGS IGU products) and the discussion of challenging topics of RT-signal processing software like error modelling, multi-system hybridizing, use of GPS L2C and L5 signals, and improved ambiguity resolution techniques due to new signals,
