Geodetic Italian VLBI: first tests

Abstract

First experiments of the Italian VLBI network (VITA) correlated in Bologna have involved the Medicina, Noto and Matera antennas. Although the scientific validity of these tests are yet to be proven, these experiments have served as a benchmark to verify a full, in-house, correlation pipeline, from the scheduling through the software correlation using DiFX to finally generating a geodetic database. A future inclusion of the Sardinia Radio Telescope, when geodetic receivers will be installed, will enhance the capability to plan ad hoc observations and strengthen the VITA network to became a basis for the definition of the national datum.
