The Italian ROSA receiver: prototype Ground Segment for the data processing through Grid Computing techniques

GPS Radio Occultation (RO), is a remote sensing technique aiming at characterizing the Earth atmosphere and ionosphere , through the inversion of excess-phase measurements carried-out by a GPS receiver placed on-board a LEO (Low Earth Orbit) satellite in radio occultation condition with respect to the transmitter. The main goal of this project is to merge RO algorithms and Grid Computing in order to apply, on one side, a collaborative engineering approach and, on the other, to reduce the time required by the overall data processing.
