abstract = "The Istituto Nazionale di Geofisica e Vulcanologia leads an
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.",
