The unit for acceleration "Frigate" after the regular separation from the third stage rocket " Soyuz-2. 1B "was successfully brought into orbit satellite" GLONASS-M ", said on Sunday correspondents in the Ministry of defense of Russia. Booster middle class " Soyuz-2. 1B " with the navigation satellite is launched on the first day of the weekend in 23. 17 Moscow time from the Plesetsk cosmodrome. As stressed in the defense Ministry, the launch vehicle and the removal of the satellite "GLONASS-M" into orbit by the upper stage block "Frigate" were in operation. "GLONASS-M" was adopted to control ground-based videoconferencing, with the spacecraft installed and maintained stable telemetry. Onboard systems of the satellite are functioning normally, said the Ministry of defence. Flying in an orbit of Sputnik joined the Russian global navigation satellite system "GLONASS" and placed on the stage of entry into the system. At present the orbital grouping of the GLONASS are 27 spacecraft, where one spacecraft of new generation "GLONASS-K" Flight test passes and one spacecraft "GLONASS-M" is placed on maintenance. This is the fourth launch of the carrier rocket "Soyuz-2" from the Plesetsk cosmodrome in 2018. Flight test a space rocket complex "Soyuz-2" was launched at Plesetsk in the fall of 2004. Over the past 14 years with the Northern cosmodrome held 36 launches of carrier rockets "Soyuz-2" upgrade stages 1A, 1B and 1C, including held on the first day of the weekend run. Rocket "Soyuz-2" came to replace carriers " Soyuz-U ", which was launched from Plesetsk from 1973 to 2012.
