Low-cost multi-frequency GNSS receivers have recently become a viable alternative to geodetic-grade instrumentation for deformation and displacement monitoring applications. Among current GNSS constellations, Galileo offers specific advantages for such applications, including signal authentication through the Open Service Navigation Message Authentication (OSNMA), which enables navigation message authentication and increases t...

The Precise Point Positioning (PPP) approach to GNSS observables is widely used for processing data from permanent stations, providing highly precise coordinates. However, the performance of PPP for observation sessions shorter than 24 h has not yet been thoroughly investigated in the case of multi-constellation acquisitions. In recent years, the PRIDE PPP-AR software package has been made freely available. Since it includes a...

The analysis of altimetric profiles in Antarctica and their evolution over the years is a sensitive topic for the scientific community since it helps understand the effects of climate change that the continent undergoes. Different geomatic techniques, including the GNSS technology, can be employed to obtain altimetric profiles. However, the GNSS differenced approaches, such as the Post Processing Kinematic, are hardly usable t...
