About the paper

Two 13-m antennas will be built at the Badary and Zelenchukskaya observatories of the VLBI network “Quasar”. These antennas will be equipped with new VGOS hardware being developed by the Institute of Applied Astronomy (IAA). While waiting for the small antennas, the first test sessions with VGOS technology were made with the 32-m antennas. A special VLBI session with the Broadband Acquisition System (BRAS) prototype was performed in late 2012 using the single baseline Svetloe–Zelenchukskaya. The main goals of this experiment were to test BRAS in a real environment and to compare it with the existing DAS R1002M.
