Glonass Satellites Launch Failed



Glonass Satellites Launch Failed
Three satellites meant to complete Russia’s Glonass GNSS system crashed into the Pacific Ocean on Sunday after a failed launch, Russian space officials said.

The satellites were the last of the batch of 24 satellites at the heart of Glonass, Russia’s answer to the U.S. Global Positioning System.

As of December 5 the Glonass constellation was made up of 26 satellites, including 20 in operation, two on standby and four under maintenance. A minimum of18 operating satellites are necessary for Glonass coverage of Russia, and 24 satellites make the system global.

The crash of the Proton rocket is therefore a step back for a reliable Glonass global coverage; however, it does not threaten coverage over the Russian Federation.
