"A Proton launcher rocketed into orbit Friday with three Glonass navigation satellites for the Russian government, delivering reinforcements for the military-run fleet of positioning and timing spacecraft.

"Powered by six hydrazine-fueled main engines, the 191-foot [58.2-m]-tall Proton rocket blasted off at 1251 GMT (8:51 a.m. EDT) Friday from a launch pad at the Baikonur Cosmodrome in Kazakhstan. The rocket soared into a dusk sky over Baikonur, where it was just after sunset."

"The three-stage Proton core launcher lofted the three Glonass satellites and a Breeze M upper stage into space in less than 10 minutes. The Breeze M rocket engine fired several times to reach an orbit 12,000 miles [19,312 km] high with an inclination angle of 64.8 degrees to the equator.

"The upper stage deployed all three satellites at 1841 GMT (2:41 p.m. EDT), according to Roscosmos, the Russian space agency."

"Built by ISS Reshetnev Co., each Glonass M satellite weighs about 3,100 pounds [1,406 kg] at launch and has a design life of seven years.

"The Glonass system broadcasts navigation signals to Russian military and civilian users around the world. It is Russia's counterpart to the U.S. Air Force's Global Positioning System."
