In 2019–2033, it is planned to launch four Glonass-M satellites, nine Glonass-K and 33 Glonass-K2.
In 2019, three Glonass-Ms and one Glonass-K and Glonass-K2 are to be put into orbit, in 2020 one Glonass-M, three Glonass-Ks and one Glonass К2 ", in 2021 - three" Glonass-K ", in 2022 - one each" Glonass-K "and" Glonass-K2 ". In 2023 it is planned to launch one Glonass-K and Glonass-K2, in 2024 four Glonass-K2, in 2025 six Glonass-K2, in 2026 two Glonass-K2 ".
In 2029, it is planned to launch three Glonass-K2, in 2030 - seven Glonass-K2, in 2031 - three Glonass-K2, in 2032 - two Glonass-K2, in 2033 - two "Glonassa-K2".
In 2025, it is planned to completely switch to the use of new-generation Glonass-K and Glonass-K2 satellites, which differ from the previous-generation Glonass-M satellites by the large number of emitted navigation signals.
In addition, in the years 2023-2025, the Glonass-V high-orbit navigation satellites will be added to the GLONASS system in order to improve the accuracy of the GLONASS system.

In the meantime, the other Glonass-M launches disappeared from the 2019 schedule.
Where does this information come from?

Since August 1, Glonass-M 717 is in maintenance. The oldest Glonass-M in the constellation.
There was a small change of the orbit. (probably at the time of failure)
The orbital period of 717 changed from 675.7 min to 676.2 min.
If no engine use was made, intentional or not, then I see black.

Yes, 742 fell silent between 10 and 11 (Glonass time) yesterday.
I did not want to post the bad news immediately.
717 continues to drift away from his working point, I think dead

I believe Glonass M-717 will soon be replaced by a new Glonass-M.

The current newspaper of ISS-Reshetnev

Quote
Outside, the Glonass-M satellite from the ground reserve will replace the long-lived spacecraft in orbit. The GLONASS orbital group will be updated by the next Glonass-M satellite. It will replace the spacecraft in orbit, which has served almost twice as much as the stipulated term - about thirteen years instead of seven.
.....
When Glonass-M leaves the ground reserve, two more brothers will remain in custody at ISS. In the meantime, the company continues to work on the GLONASS-K and GLONASS-K2 devices. Their launches are also just around the corner.

Yes, the launch will be in the middle of November.

Will this be satellite No. 59?  (This and Nos. 60 and 61 should be the remaining "stock.")

Four weeks no signal from Glonass M 742. I think he is dead.

The death of Glonass M 717 is more or less officially.
It is remarkable, that the orbital period in the Glonass ephemeris for 717 (sat no.10) does not fit the orbital period according to NORAD TLE.
Both are updated regularly.
https://www.glonass-iac.ru/en/GLONASS/ephemeris.php
https://www.n2yo.com/satellite/?s=29671

22 satellites in operation.
Glonass M 733 probably without L2 signal.

Reserve satellite Glonass M 723 maneuvered.
Currently at slot 12, the orbit has been lowered, probably drifting to slot 10 (Glonass M 717)

Yes, 723 will replace 717, and (7)59 will replace 742.

Glonass M 59L is planned for mid-November.
In the NK forum it says: Mid-November Glonass K 15L

Yes, 723 will replace 717, and (7)59 will replace 742.
The commissioning of 723 is obviously already started. He is still next to slot 12.
I think, he will transmit on a extra channel as a "pseudo no.10" during the drift.
The drift of 723 is currently very slow. duration to Slot 10 4 months or so, fuel saving?

Glonass-M 723 is now in operation. In almanac as satellite no. 10, physically between slot 12 and 11, crawls slowly to slot 10. Probably only L1 signal (since 2016).

We will see. The need is great.
In addition to 717 and 742, on November 16 Glonass M 731 and today Glonass M 735 failed.
731 and 735 are in the plane 3. The launch was in March 2010.

Crosspost from Plan of Russian space launches
Glonass M 735, plane 3/slot 24 can not be saved.

The launch of the Glonass-M backup satellite, which will have to replace a similar spacecraft with system number 735 in space, is scheduled for February 5 or 12, ”the agency’s source said.

Again a Glonass-M as replacement. (the second to last)
When does the first Glonass-K satellite launch with import replacement components?
How will that work?

Interesting news from the insurance conference: 1. This year, 3 launches of Glonass satellites: M No. 60 in March, K No. 15 in the 2nd quarter, K No. 16 at the end of the year. M No. 61 for operational necessity; 2. Launch of Glonass-K No. 15-23 in 2020-2022, Glonass-K2 No. 24 in 2023;
