The Centre Tecnològic de Telecomunicacions de Catalunya (CTTC) is a non-profit research institution based in Castelldefels (Barcelona), resulting from a public initiative of the Regional Government of Catalonia (Generalitat de Catalunya).

Research activities at the CTTC, both fundamental and applied, mainly focus on technologies related to the physical, data-link and network layers of communication systems, and to the Geomatics.

The Geomatics Division develops what is understood as the “Geomatics discipline”, that is to say, a variety of techniques that integrate sensors that capture data and images (basically cameras and other remote sensors) with methods for the treatment, analysis, interpretation, diffusion and storage of geographic information. It connects various traditional disciplines, like geodesy or cartography with more recently developed fields like remote sensing, satellite navigation and latest information and communication technologies. As a result, geomatics allows us today to obtain information about the Earth and her atmosphere globally and within very short time.

The Geomatics Division centres its activities in two main areas: the area of positioning and navigation, focused on techniques that allow the improvement of precision, and the area of remote sensing, which means Earth observation through images and data collected by sensors onboard of satellites and aircrafts, and ground-based sensors.
