Are any Glonass satellites expected to launch before the end of 2021?

Tell us which satellites will join the GLONASS constellation in the near future?- This year, our enterprise will complete the manufacture of three Glonass-K spacecraft, but their launch will be carried out only when necessary. Let me explain: 23 devices are currently operating in the GLONASS system, covering all the needs of customers. In addition, one device "Glonass-K" is in flight tests and will enter service in a few months. Accordingly, the need to launch a new satellite will come only after the failure of one of the spacecraft operating in space. This is the "operational necessity".Among the plans for the next year we have the launch of the first device "Glonass-K2". We are continuously working on preparing it for launch, but unfortunately, questions arose about the work of onboard mathematics. For development work on a new satellite, this is a common situation that cannot be predicted in any way. Unlike the Glonass-K satellites and the Glonass-M devices of the previous generation, the new Glonass-K2 is a multifunctional device, so it becomes necessary to adjust the work of internal mathematics with all systems. The more instruments, the more combinations you need to work out. The device itself is assembled, we will withstand the obligations for its manufacture by the end of the year. Earlier it was reported that the cost of new satellites "Glonass-K2" will be twice as high as that of their predecessors - "Glonass-K". Why is that? Is it connected with the installation of additional equipment on the satellite, the import substitution program?- There is a complex of reasons. First, the first Glonass-K2 are being assembled on a foreign component base. The dollar has doubled. The cost of import-independent devices, which will go from 2026, in turn, requires redesign work. Secondly, Glonass-K2 differs from its predecessors in the presence of additional equipment. He is even physically one and a half times heavier. Thirdly, the prices for components have increased. Take the deflator 5% per year and multiply it by 10 years that have passed since the launch of the first Glonass-K. Just by multiplying the deflator, you will already get a twofold increase. That is, the doubling that has taken place is an absolutely natural process.- The last GLONASS satellite of the previous generation, Glonass-M, has not been launched into orbit, which this year is ending its ground storage period.- We have extended the storage period until the end of this year and will extend, if necessary, until the middle of next. Considering that our similar devices are guaranteed to work for one and a half terms, we are absolutely sure that this device will also work after the launch of the warranty period of seven years.- Has the work begun on the creation of satellites for the highly elliptical segment of GLONASS?- The creation of the segment is included in the GLONASS subprogram of the Space Activities of Russia until 2030 program. A contract is being prepared, tactical and technical requirements for the system and spacecraft are being written. We expect that funding for the work will begin this year.- Do you plan to carry out any work on the Small GLONASS project, small and cheap navigation satellites?- In the previously announced subprogram, research work on the creation of a platform for a small navigation apparatus is spelled out. Work on this topic also begins this year.

So no need for new satellites in the constellation? Only 23 satellites in operation, one too few.

Assuming all will go well with said tests?It's probably a more palatable statement from him for internal consumption, than to say "We're one short, and a few more are marginal at best."

Not the first attempt.When the young 753 collapsed on slot 11, it became 705 redirected there. Glonass no.11 is not usable since 11 months.My opinion:So you would have had to launch another satellite (Glonass-M 61L / 761), perhaps between slot 10 and 11 and put it into operation there as number 11. There are 2 free channels so it does not disturb the other satellites.If Glonass-K 705 is ready one day, it will take over number 11. Glonass-M 761 would be moved to slot 10 and will finally replace 723.The fact that Glonass-M 61L is held on the ground instead can only mean that Glonass-K 705 and thus its successors are still not ready for use. Software?The only ready-to-use replacement satellite should still be saved.
https://ria.ru/20211220/glonass-1764483094.htmlThe current plan is to launch the first Glonass-K2 satellite in the second quarter of 2022 followed by the second Glonass-K2 satellite in the following quarter. It was also added that the final Glonass-M satellite currently in reserve will most likely be launched in the first quarter.
MOSCOW, 30 June. /TASS/. Roskosmos plans to send a new generation navigation satellite into orbit in August this year. This was reported to Russian President Vladimir Putin by the head of Roscosmos Yuri Borisov on Friday."We support the GLONASS constellation, which gives the appropriate accuracy. In August, our plans are to launch a new generation device, Glonass-K2," Borisov said.
