In November 2014 GLONASS time scale description was officially introduced at the 9th Meeting of United Nations International Committee on Global Navigation Satellite Systems (GNSS). The principles of GLONASS time scale generation and its synchronization to Russian national time scale UTC(SU) are introduced in the paper. The main ways to increase the accuracy of GLONASS time scale and UTC(SU) broadcast by GLONASS are also described.

Dual-frequency Time Transfer Unit (TTU) using GLONASS and GPS signals developed at 'Russian Institute of Radionavigation and Time' JSC (RIRT) is intended for determining the offset between local clocks and GLONASS-time and GPS-time with the purpose of subsequent determining the mutual time and frequency offset between remote clocks, as well as for generating time scale signals synchronized to Russian National Universal Time Coordinated UTC(SU). The results of tests showed that the accuracy characteristics of the new Time Transfer Unit are higher than the same characteristics of the previous TTU model developed at RIRT as well as of TTS-3 and TTS-4 receivers, mostly when operating by GLONASS signals. © 2013 IEEE.
