The GLONASS orbital group has the necessary reserve to work efficiently,
Russian Deputy Prime Minister Dmitry Rogozin said at a meeting at the
Government House on Friday.
"The developed space group of the GLONASS system has the necessary
orbital reserve and the crash which happened should not lead to the
decrease of its efficiency, however it is necessary to compensate for
the loss of satellites in the future," Rogozin said.
The Proton-M rocket, launched at the Baikonur cosmodrome on July 2, was
to put into orbit three GLONASS satellites. The rocket fell and exploded
near the launch site within minutes.
Early launch likely cause of Proton-M failure
Early launch is seen among the most likely cause of the recent Proton-M
rocket failure and the loss of three satellites, a Russian space
industry source familiar with the investigation said on Thursday.
The source said a special commission is still investigating the incident, several versions are being considered.
One of the versions is that, for yet unknown reasons, an early start
took place and resulted in the failure. The control system treated it as
an emergency situation... and started to divert the rocket away from
the launch pad, the way it was programmed. This version prevails," the
The Proton-M rocket was carrying three Glonass navigation satellites
when it exploded shortly after launch early on Tuesday from the Baikonur
space center in Kazakhstan.
Rocket crash may be due to premature engines ignition: space agency
The failed launch of the Proton-M rocket this week could be caused by
premature launch, head of the Russian space agency Roscosmos said on
"This is obvious that the rocket blasted-off before its engines started
work on full capacity," Vladimir Popovkin told reporters.
According to Popovkin, the rocket engines were ignited 0.4 seconds before the planned time.
He said the reason why the lift-off happened prematurely should be investigated.
Experts consider various other possibilities, including malfunctions in
the launch-pad equipment, rocket guiding device and first-stage engines,
Investigation must be completed in July, Popovkin added.
The Proton-M carrying three communications satellites crashed Tuesday 17
seconds after lift-off from the Baikonur space center in Kazakhstan.
The rocket fell about 2.5 km away from the launch pad.
Another Proton-M rocket also failed to reach orbit in 2012.
