Source: satellite launch "GLONASS" a new generation from Plesetsk postponed
The launch from Plesetsk navigation satellite of new generation "GLONASS-K", which is regularly postponed from March, was postponed for October, told RIA Novosti source in the space industry.
In early August, another Agency source in the industry said that the launch rescheduled for the end of August - beginning of September.
"The launch of the satellite "GLONASS-K" is postponed for October, tentatively on the 17th number. No technical obstacles for him there," - said the Agency interlocutor.

A new generation of satellites "GLONASS-K and GLONASS-K2" are different from the device of the previous generation "GLONASS-M" a large number of emitted navigation signals (five signals in "GLONASS-M", seven, and nine - "GLONASS" and "GLONASS-K2") and long life (seven years, "GLONASS-M" 10 years - "GLONASS" and "GLONASS-K2").
Now the Russian orbital group global satellite navigation system GLONASS includes 27 spacecraft (25 "GLONASS-M" and two "GLONASS-K"), of which 23 work on purpose, one is for flight tests, one in service and two in reserve. For global coverage of the Earth of navigation signals of the system requires 24 operational satellites.
