The GPS-DS campaign was deployed in Antarctica as a second part of ESA funded project GPS-SIDS (Sea Ice and Dry Snow), whose objective was to investigate the viability of using reflected GPS signals to study sea-ice and dry snow properties from space. To fulfill this target, the goal of this campaign was to obtain continuous data sets monitoring a dry snow protected area from a fixed platform placed at Dome Concordia. With penetrations depths around 100 meters, it is expected that GPS signals will infer information of the internal properties of continental ice masses. In addition, it will contribute to a better understanding of the L-band radiometric measurements. Afterwards, the results should be extrapolated to a spaceborne platform. As in the first part of GPS-SIDS, the GNSS-R instruments employed were the ICE/IEEC-CSIC's GOLD-RTR and the GFZ's GORS. The equipment was installed on the top of a 45 meters high tower. From the 10th until the 21st of December 2009, almost 10 days of continuous records were stored. The experimental data acquisition was carried on in-situ by IFAC-CNR in remote coordination with ICE/IEEC-CSIC and GFZ.
