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.

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) on Nov 4, 2011 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 UCT (2:41 p.m. EDT), according to Roscosmos, the Russian space agency.
This is the Block 44 Glonass launch, with satellites Uragan-M No. 743, 744 and 745, also known as Glonass-M No. 43, 44 and 45.
On Nov 12, 2011 the satellites were in orbits of 18907 x 19172 km x 64.8 deg, 19160 x 19319 km x 64.8 deg, and 19018 x 19178 km x 64.8 deg.
