GEROS-ISS: Analysis of reflection points

GNSS Reflectometry, Radio Occultation and Scatterometry on-board the ISS ("GEROS") is a proposed experiment to install an instrument on the Space Station that would perform reflectometry and radio occultation using GNSS signals of opportunity. In this paper the analysis of visible GNSS reflections and radio occultation events to support the design of the payload instrument performed in the context of Phase A studies (feasibility phase) is here presented.
