MOSCOW (Sputnik) – The testing of the Glonass system started in 2011. In December 2015, the Russian Defense Ministry was put in charge of the systems’ final tests.
"The tests ended successfully, otherwise the system would not have been accepted. I want to give credit to our customers – they are demanding people and if something was not in line with their technical objectives they pointed it out and we worked it through, modernizing some things," Testoyedov told Izvestia.
The system currently consists of 28 satellites, of which 23 are operational, and a number of ground relay stations.
On Wednesday, head of Roscosmos Igor Komarov,announced that the Russian space agency would transfer control over the ground infrastructure of the Glonass global positioning system to the country's defense ministry later this year.
