The Sardinia Radio Telescope (SRT) is a large, fully steerable radio telescope completed in 2011, near San Basilio, province of Cagliari in Sardinia, Italy. It is a collaboration among the Istituto di Radioastronomia di Bologna, the Cagliari Observatory (Cagliari) and the Arcetri Astrophysical Observatory (Florence).

The main technical points are:

• A 64 meter primary mirror with a 7.9 meter secondary;
• A Gregorian configuration with shaped surfaces
• An active surface: Primary mirror adjustable with 1116 actuators;
• 0.3–115 GHz continuous frequency coverage
• Three main focal points: Primary, Gregorian, and Beam Wave Guide
• Primary surface accuracy: ≈150 μm RMS
• Maximum antenna efficiency: ≈60 %
• Pointing accuracy (RMS): 2-5 arcsec
