The radio interferometer of new generation, created in the Institute of Applied Astronomy at the stations of "Quasar" VLBI network is considered. Currently this new radio interferometer consists of two antennas with a mirror diameter of 13.2 m installed at the "Badary" and "Zelenchukskaya" observatories. All installation works of the antenna systems were carried out by the end of 2014. Antenna control system and subreflector were successfully tested. Tri-band Receiving System was installed on the antennas of the radio interferometer. The first observations of calibration radio sources were carried out at the "Badary" observatory. Processing and analysis of newly obtained data showed that the radio interferometer of new generation allows to operate as a part of the International and European VLBI networks and having an accuracy of 3 mm for pole coordinates, 100 microsecond of arc for the nutation and precession angles and no more than 10 μs for the Universal Time determination, that meets all requirements of the VGOS program.
