Apparently they've tried a test impulse and it works
Now they're waiting for the window of opportunity to do it
If it works then the Nauka will take longer than scheduled to meet up with the ISS, but it'll get there

Moscow. July 22. INTERFAX - The Nauka module has successfully completed a test orbit correction, its engines are operating normally, Roskosmos reported.
"The test firing of the propulsion system of the # Science module and the orbit formation impulse have been worked out routinely," the state corporation said in a tweet.

So Zak was spreading misinformation.
Doing a favour for his "homeland".

On Thursday, July 22, 2021, specialists of the flight control group of the multipurpose module "Nauka" in the Moscow Region Mission Control Center conducted two corrective maneuvers of the module launched the day before to the International Space Station.
The first maneuver took place at 18:07 Moscow time, when the engines of the module were turned on for 17.23 seconds. The impulse value was 1 m / s. The second switching on of the engines took place at 20:19 Moscow time and lasted 250.04 seconds. The impulse was 14.59 m / s.
Orbital parameters after two impulses:
Orbital period : 90.17 min;
Orbit inclination : 51.64 degrees;
Minimum orbital altitude : 230.43 km;
Maximum orbital altitude : 364.86 km.
Thus, the telemetry data confirmed the operability of the module's propulsion system. The next pulses for further orbit building are scheduled for tomorrow, July 23rd. Undocking and flooding of the Pirs module is scheduled for Saturday 24 July.

Thanks for the info update. Good to hear Nauka is in nominal state.
According to Igor Lisov on the NK forum, Nauka needs to make a major maneuver pretty soon (preferably today) to still make it to the ISS. Nauka was launched 1.5° out of plane with the ISS to allow it to make a leisurely 8-day approach to the station. However, since Nauka is in a much lower orbit than it should be by now, the orbital plane is precessing faster than expected and will converge with that of the ISS too soon if no major burn is performed today to slow the approach speed. The two relatively small maneuvers carried out yesterday have not done much to change that situation. If the orbital planes converge before Nauka reaches ISS, Nauka will have to be maneuvered into an orbit higher than that of the ISS for the orbital planes to drift back to one other, but there is not enough propellant for that, according to Lisov.

ZHUKOVSKY (Moscow region), July 24 - RIA Novosti. The station for tracking the signals of the Russian global navigation satellite system GLONASS will be located in India and, possibly, in Indonesia , Vladimir Pasynkov, general designer of the Precision Instrumentation Systems Research and Production Corporation, told RIA Novosti.
“We have been instructed to prepare the deployment of a GLONASS-free measuring station in the Indian city of Bangalore . It is also possible to install such a station in Indonesia,” he said at the MAKS-2021 International Aviation and Space Salon.
According to him, the placement of these stations will significantly improve the characteristics of the Russian high-precision navigation system.
"Agreements have already been reached with the Indian side, everything is determined by the terms of legal registration of documents," Pasynkov added.
At present, the overseas segment includes five Russian GLONASS free measuring stations located in Brazil , South Africa and Cuba .

MOSCOW, July 24 - RIA Novosti. The multifunctional laboratory module "Science", after the orbit corrections carried out on Saturday, entered the calculated flight trajectory, said the head of Roscosmos Dmitry Rogozin in his Telegram.
"At 17.20.47 and 17.54.20 Moscow time, a two-pulse correction of the MLM Nauka orbit was carried out on the main correction and rendezvous engine number 1. The parameters of the MLM Nauka orbit correspond to the calculated ones," he wrote.
The day before , the Mission Control Center twice adjusted the flight altitude of the Nauka multifunctional laboratory module, and the first maneuvers were carried out on the 22nd. The module docking to the ISS is planned for July 29.

I love my German neighbours, we've run a long road understanding each other, and the sane of us succeded ...
But unfortunately, I can't see a German GPS running, or in a pipeline?
Where is a GPS of France?
Or UK?
All of them combined, struggling to make a Galileo living ...
Fly high, see the perspective.

Russia was a leader in the development of space technologies as the USSR, spending over 40 years huge sums on the development of all space technologies. Now they take advantage of it.
They have many solutions, technologies, etc. already ready.
. Is the result of 50 years of R&D on many systems, solutions, etc.And invested enormous forces and resources.
So in my opinion it is hard to compare Russia even with the largest EU countries, if we want to compare the capabilities of their MIC or space industries.
