The Russian Satellite News Agency was told by an aerospace industry source that they are preparing to bring five Glonass navigation satellites into orbit this year, including four next-generation satellites. Nikolai Gestoyedov, general manager of Reshetnev’s Information Satellite System International Space Station, reported that the Glonass-K2 flight test is scheduled to launch in 2021, and Russia plans to develop 15 such satellites.
This year, five satellites are expected to be launched: the last Glonass-M satellite will be launched this year; two Glonass-K satellites will be launched in the second and third quarters; and two Glonass-K2 satellites will be launched in the third and fourth quarters. Launch quarterly.”Five satellites are planned to be launched this year: the last Glonass-M satellite will be launched within this year; two Glonass-K satellites will be launched in the second and third quarters; and two Glonass-K2 satellites will be launched in the third and fourth quarters. Quarterly launch.”
Russia launched the third Glonass-K satellite into orbit in October last year. Since March, the launch of this satellite has been postponed several times because of development delays induced by the COVID-19 pandemic.
In 2003, Russia started releasing Glonass-M satellites, and more than 50 satellites of this old type have already been manufactured. The Glonass-K model produces more navigation signals than Glonass-Ms and has a longer service life. In February 2011, the first and more advanced Glonass-K satellite was deployed, and in December 2014, the second was launched.
There are currently 28 satellites in the Russian Glonass navigation constellation, of which 23 are in service and 2 are under repair. In February, Russian satellite maker ISS-spokesperson Reshetnev’s said that the constellation will add nine next-generation Glonass-K satellites by 2022.
