MOSCOW, December 14 (Reporters Nieyun Peng) 俄罗斯赫鲁尼 Qiefu National Space Centre spokesman 博布列涅夫 14 announced that Russia successfully launched three that afternoon, “GLONASS-M” global satellite navigation system.
博布列涅夫 said Moscow time at 13:38 on the 14th (GMT 18:38), 3 “GLONASS-M” navigation satellite aboard a “Proton-M “carrier rocket from the Baikonur Cosmodrome in Kazakhstan’s successful launch is expected in Moscow time 17:10 (GMT 22:10), the satellite will be separated with the rocket and entered its orbit.
This is the first time this year, Russia launched the “GLONASS” satellite navigation system.博布列涅夫 said the satellite launch is designed to increase the Russian “GLONASS” navigation system the number of satellites in orbit. The system is currently a total of 19 orbiting satellites, including 16 works, the other two temporary technical maintenance, as well as one about to retire.
Russia planned to launch this year a total of 6 2 “Glonass” satellites, respectively, September and December. Originally scheduled for September launch satellite was delayed for technical reasons to launch next year. “GLONASS-M” belongs to a new generation of satellite navigation satellite, satellite, weighing 1415 kg, in-orbit life of 7 years from the 俄罗斯列舍特涅夫 satellite information systems manufactured.
“GLONASS” system developed by Russia alone deployment, the program began in the 1970s. The system requires at least 18 satellites to provide for the whole territory of the Russian satellite positioning and navigation services, such as to provide global service, you need 24 satellites in orbit. In Russia to complete all the satellites to deploy the system, its satellite navigation range can cover the entire Earth’s surface and near-Earth space, positioning accuracy will reach 1.5 meters.
This is the ninth this year, Russia launched the “Proton-M” carrier rocket. “Proton-M” carrier rocket by the National Space 俄罗斯赫鲁尼 Qiefu production research and production center, launch vehicle for the three liquid-fuel rocket, a launch weight of about 700 tons.
