The GLONASS-K satellite lifted off on the Soyuz rocket at the Plesetsk Cosmodrome, about 800 km (500 miles) north of Moscow.
GLONASS-K is a navigation satellite intended as a part of the Russian GLONASS radio-based satellite navigation system. Russia has spent billions of dollars in the past two decades on developing the GLONASS system seen as a potential rival to the U.S. global positioning system (GPS).
