The first launch is scheduled for December 25, 2017, the other two – for November 25, 2018. The satellite will be carried by a Soyuz-2.1b rocket from the Plesetsk Cosmodrome spaceport.
In February and May 2016, two Glonass-M satellites were added to the GLONASS system. Currently, the system involves 27 satellites, 23 of which are in operation, two are put in orbital reserve, one is undergoing flight tests, and the last is undergoing maintenance.
In the event of a military conflict, communication satellites would be an important target, military expert and observer Viktor Baranets said.
"The current situation in space is that no satellites are protected, no matter at what orbits they are. The reason is that alongside with development of space systems, the US is running on all cylinders developing space weapons," Baranets told Radio Sputnik.
"Russia has its own plans too. I think that if Washington keeps ignoring Russia’s calls for the demilitarization of space, the so-called 'combat cosmonautics' would become reality," Baranets pointed out.
His words were echoed by Russian defense expert Vasily Kashin. In an interview with Sputnik China, Kashin said that modern satellites are almost devoid of any opportunity to protect themselves from the impact of interceptor missiles.
Before Barack Obama became president, during his presidential campaign, he called for talks with Russia on anti-satellite weapons which started back in the 1970s but then was terminated by Washington. However, no progress has been made on the issue.
Baranets said it could not be ruled out that in the future space might be militarized which would pose a threat to the entire world.
"Mankind will have to decide whether to militarize space or not. There are very difficult negotiations in process. Moreover, the US wants to pass a bill to declare certain orbits exclusively American," Baranets said.
The expert stressed that the 1967 Outer Space Treaty between the US, the USSR and Britain should be revised. The document represents the legal framework of international space law, including prohibition of weapons of mass destruction in orbit.
"The treaty should be revised as soon as possible. This will prevent militarization of space. Now, space is becoming a place for effective strikes against the enemy," the expert concluded.
In turn, Kashin assumed that anti-satellite weaponry is a new reality that should be considered while planning a possible military operation.
In this new reality, Russia, China, the US, as well as India and Iran will most likely possess domestically-made sophisticated anti-satellite weapons, according to him.
