                         Research and Application for Polar Environment (DemoGRAPE) is an 
                         international project leaded by the Istituto Nazionale di Geosica 
                         e Vulcanologia (INGV), in partnership with Politecnico di Torino, 
                         Istituto Superiore Mario Boella, and South African National Space 
                         Agency (SANSA) and the Brazilian National Institute of Space 
                         Physics (INPE) as collaborators. The aim of project is to improve 
                         satellite navigation particularly in Antarctica, where the 
                         accuracy is of paramount importance for the surface displacements, 
                         and it is strongly aected by atmospheric disturbances. The 
                         DemoGRAPE activities started on November 2015 with the system 
                         installed at Brazilian Antarctic Station Comandante Ferraz (EACF, 
                         62o 0507'S, 58o2329' W) located in the King George Island. To 
                         investigate the ionospheric disturbances from high to low 
                         latitudes in the South American sector we present the GNSS 
                         scintillations observed during 2016 at EACF inside DemoGRAPE 
                         activities, which are combined with GNSS observations done at 
                         Universidade Mackenzie in S~ao Paulo (2332'56{"}S, 4638'20{"}W, 
                         inside the South American Magnetic Anomaly - SAMA) and at Cauam^e 
                         Campus of Universidade Federal de Roraima (024912'N, 604023' W). 
                         The goal is to characterize the occurrence of scintillations in
