GLONASS, or Global Navigation Satellite System, is Russia's counterpart to the American GPS. It provides accurate positioning and timing information to users worldwide, utilizing a constellation of satellites orbiting the Earth. GLONASS is essential for various applications, including navigation for vehicles, aircraft, and maritime operations. The system was developed by the Russian Federation and became fully operational in 1995. It plays a crucial role in enhancing the accuracy of location services, especially in regions where GPS signals may be weak or obstructed. GLONASS is vital for both civilian and military uses, ensuring reliable navigation capabilities.
