Dates no longer current, but shows the numbers of those assigned to Proton and those to Soyuz.

The Glonass constellation has ended operations on two of the "inactive" satellites. One was listed as a spare and the other as "under check by the SPC" until august 28.

Glonass coverage will be sub-optimal at least until the sat that will launch on september 22 become active... And then, there will be no spares. Note that at year's end, 6 of the 23-24 active sats will be older than 10 years.

"And then, there will be no spares."

Not in space but there are six GLONASS-M spares on the ground, which can be launched on demand (http://gpsworld.com/glonass-m-satellite-shipped-to-cosmodrome-for-launch/).

Yes of course I meant in orbit spares.

In-demand launch is maybe the appropriate term, but not necessarely the fastest system to cover the constellation capability. Coverage is 23/24 sats since early july, launch will happend end of september and service about a month later.

Why is the constellation kept with no on-orbit spares (which will prompt some level of disruption to the service every time a sat fails)? Is the disruption too small to be of importance and preferable to having unneeded sats degrading in space? Or is it just a cash problem? Maybe some twisted political issue?

Sept. 22: A Soyuz-2-1b/Fregat-M rocket to launch the GLONASS-M No. 52 satellite from Plesetsk for Russia's global satellite navigation network, GLONASS. The spacecraft was built by ISS Reshetnev based in Zheleznogorsk, Russia, more than two years prior its launch and put in storage to serve as a spare vehicle. The launch of GLONASS-M No. 52 was earlier planned for Sept. 6, 2017, but in July 2017, it was postponed to Sept. 22 of the same year. On Aug. 25, 2017, ISS Reshetnev announced that GLONASS M No. 52 had been air-shipped to Plesetsk aboard an Il-76 transport plane. At the time, the company still had six GLONASS-M satellites in stand-by mode on the ground for the replenishment of the GLONASS constellation on the "as-needed" basis.

After GLONASS-M is flown out GLONASS-K2 and then GLONASS-KM will be flown instead in that order.

Soyuz-2.1b №У15000-039 has been delivered to Plesetsk, for the launch of a GLONASS satellite.

Based on previous information I think it could have factory serial number 1/137.

There are two contracts for the delivery of three rockets in 2017: №353-С387/16/70 and №353-С365/17/41. It is the 2nd contract that has a document accepting Soyuz-2.1b №У15000-039 has been delivered, dated September 2017. That detail is not yet provided for the 1st contract.

Any updated information on the Glonass-K2 satellites and their launch schedule?
