In the Big Data era, the amount and complexity of astronomical data more and more often prevents the scientist from locally store and process her/his data. As a consequence, the geographically distributed approach to data archiving and processing is rapidly becoming a requisite. To fulfill this need, we are realizing a prototype of Science Gateway (SG) for the Italian radio telescopes. The huge amount of significantly complex and resource-demanding datasets delivered by the Italian radio telescopes and the variety of use cases from the different observing modes represent an ideal test bed for the implementation and verification of a SG environment where the scientists can exploit, manage and analyse data. To this aim, we are exploiting our previous experience in the realization of a geographically-distributed radio data archive and processing tools as well as in the design of SG prototypes. Such a coordinated approach and harmonization of resources will maximize the return for the Italian observing facilities and, moreover, will match the requirements of the international community for a state-of-the-art, highly-performant environment in which to conduct successful science.

We present the status of the Sardinia Radio Telescope (SRT) and its forthcoming update planned in the next few years. The post-process scenario of the upgraded infrastructure will allow the national and international scientific community to use the SRT for the study of the Universe at high radio frequencies (up to 116 GHz), both in single dish and in interferometric mode. A telescope like SRT, operating at high frequencies, represents a unique resource for the scientific community. The telescope will be ideal for mapping quickly and with relatively high angular resolution extended radio emissions characterized by low surface brightness. It will also be essential for spectroscopic and polarimetric studies of both Galactic and extragalactic radio sources. With the use of the interferometric technique, SRT and the other Italian antennas (Medicina and Noto) will operate within the national and international radiotelescope network, allowing astronomers to obtain images of radio sources at very high angular resolution.
