Yesterday, September 25, Russia has launched three more GLONASS satellites. Currently there are 14 active GLONASS satellites plus 1 satellite in maintenance and 1 in decommissioning. So the number of GLONASS satellites should rise to 17 satellites and maybe even 18. The next GLONASS launch is planned, as is almost tradition, around Christmas this year, which will increase the number of active GLONASS satellites even further.
