Stupak said, Russia this year will complete the upgrade program of research, demonstration and simulation, and increase the number of satellites will greatly improve the precision of the navigation system, improve the performance in the environment in the city.

Compared with GPS, GLONASS system in the equatorial region of the navigation ability also slightly lacking, increase the number of satellites make up the shortfall. By 2020, GLONASS, the precision of the navigation system will reach 0.6 meters.
