GReD is an Italian SME that studies, designs and implements innovative and customized solutions based on geodesy and geomatics techniques, mainly in two fields of application: precise GNSS positioning and gravimetry. In the field of GNSS positioning, GReD started an end-to-end monitoring service to detect displacements of structures and ground movements, based on cost-effective GNSS instruments. The monitoring service, called GeoGuard, was developed in collaboration with the Italian company algoWatt SpA, and is successfully applied to dams, bridges, penstocks and landslides. GReD GNSS activities include also tropospheric delay monitoring from either geodetic or low-cost stations, for meteorological applications. As regards gravimetry, GReD designs and develops innovative solutions for the analysis of aerogravimetric data and its geophysical interpretation for oil&gas exploration.
