                         international project funded by the Italian National Program for 
                         Antarctic Research, called Demonstrator of Global Navigation 
                         Satellite System (GNSS) Research and Application for Polar 
                         Environment (DemoGRAPE), in partnership with Politecnico di 
                         Torino, Istituto Superiore Mario Boella, and with South African 
                         National Space Agency and the Brazilian National Institute of 
                         Space Physics, as key collaborators. DemoGRAPE is a new prototype 
                         of support for the satellite navigation in Antarctica. Besides the 
                         scientific interest, the accuracy of satellite navigation in 
                         Antarctica is of paramount importance since there is always the 
                         danger that people and vehicles can fall into a crevasse during a 
                         snowstorm, when visibility is limited and travel is restricted to 
                         following specified routes using satellite navigation systems. The 
                         variability of ionospheric delay and ionospheric scintillation are 
                         two of the primary factors which affect the accuracy of satellite 
                         navigation. The project will provide a demonstrator of cutting 
                         edge technology for the empirical assessment of the ionospheric 
                         delay and ionospheric scintillations in the polar regions. The 
                         scope of the project includes new equipment for the recording and 
                         dissemination of GNSS data and products installed at the South 
                         African and Brazilian bases in Antarctica. The new equipment will 
                         facilitate the exchange of software and derived products via the 
                         Cloud computing technology infrastructure. The project portal is 
                         accessible at www.demogrape.net. We report the first Global 
                         Navigation Satellite System (GNSS) signal scintillations observed 
                         in Antarctica.",
