The VGOS Program is being implemented in Russia to create the new generation of VLBI systems. The new generation radio interferometer provides implementation of perspective requirements for determining and predicting the Earth orientation parameters. The work was started in 2012, and the two-element radio interferometer will be created by the end of 2015 at the Badary and Zelenchukskaya co-location stations. The program includes the creation of two fast moving 13.2-m radio telescopes equipped with the receiving systems which will receive radio signals at three bands (S, X, and Ka) and two circular polarizations simultaneously. The digital broadband acquisition system provides a conversion to the 1 GHz band. The VDIFformatted digitized data will be transferred to the St. Petersburg Correlation Processing Center by the communication channels. The current state of the program is presented.
