The inspector thing has started moving higher, if the latest TLE set is valid.
Upd: The elset was erroneous.

Online Galactic Penguin SST

http://novosti-kosmonavtiki.ru/news/34836/ reported that the "inspector satellite" that separated from Kosmos 2519 has been assigned as Kosmos 2521, leaving GLONASS-M #752 launched today as K-2522.

Maybe the story has been taken down - the links to the piece do not seem to be working.   Apologies.   The story was simply saying that "The inspector satellite, coupled with the Kosmos-2519 platform, was launched on June 23. The satellite undocked from the platform, performed an autonomous flight, changed its orbit, conducted an inspection, and returned to base".

I found this in NK-Forum:
http://www.militarynews.ru/story.asp?rid=1&nid=465067
Google translation:
Moscow. 26 October. Interfax - Russian space forces conducted a successful test of the satellite-inspector, who can fly to other orbital vehicles, the Izvestia newspaper wrote on Thursday.
       "During the tests to control the maneuvering military satellite, ground and orbital communications were tested, ballistic calculation methods and new software were tested," the newspaper reports referring to the Defense Ministry.
       It is noted that the Space Forces were also able to confirm the automatic separation of the satellite from the platform, the remote control of its flight, the use of on-board equipment, including surveillance equipment, as well as the transfer of received data to the ground and their processing.
       The space platform "Kosmos-2519" with the satellite-inspector was launched on June 23. During the tests, the satellite undocked, began an autonomous flight, changed the orbit, and then returned to it, having made an inspection, the newspaper writes.
       According to the Russian Main Center for the Exploration of the Space Environment, similar projects are being implemented by the United States and China.

Here's the orbital period vs time (host, red; inspector, blue)
The question is whether 'returned to base' just meant returned to prox ops or actual redocking?

The lack of accuracy in the TLEs does not allow us to definitively decide whether the two satellites have docked or if they are just close together.

Google translation:

The Russian Space Forces successfully tested a maneuvering military reconnaissance satellite capable of flying up to other orbital vehicles and inspecting them. Such devices will allow to determine the functionality of foreign spy satellites, and also, if necessary, to create space fighter-satellites on their basis.

According to domestic experts, maneuvering satellites-inspectors will become an important element of the Russian orbital grouping, they will play the role of a deterrent in the space military race.

As Izvestia was informed by the Defense Ministry, in the course of tests to control a maneuvering military satellite, ground and orbital communications were tested, ballistic calculation methods and new software were tested. Confirmed the capabilities of the Space Forces to automatically undock the satellite from the platform, remote control of its flight, the use of on-board equipment, including surveillance equipment, as well as the transfer of received data to the ground and their processing.
According to Izvestia, during the tests the maneuvering satellite undocked from the space platform Kosmos-2519, launched on June 23, 2017, and began an autonomous flight. First, he changed the orbit, and then managed to return to the platform and perform its inspection.
According to the Russian Main Space Exploration Center, projects for the creation of spacecraft capable of changing their orbit and approaching other space objects on command from the Earth are also being implemented by the United States and China. So, in July 2013, Western media reported that China experienced three small satellites. Experts suggested that the tests were conducted within the framework of the secret program for the development of an anti-satellite system. One of the three vehicles was even equipped with a manipulator.
Independent military expert Valery Mukhin told Izvestia that the satellites-inspectors are an important component of the orbital forces of any space power.
"In the case of a global conflict, it is extremely important to destroy the enemy's satellite grouping in order to deprive them of communication, navigation and the possibility of reconnaissance, so the idea of ​​creating such fighters appeared," the expert said. - In the USSR, for example, tests were conducted, during which one satellite flew to another and exploded, hitting the target with fragments. After these experiments, there were even attempts to create armored satellites.

According to Valery Mukhin, the main task of the orbital "inspectors" is to establish the purpose of the vehicles placed by the potential enemy in orbit.

- By the appearance of the object, its design, the location of the equipment can make assumptions about its purpose, - explained the expert. - In addition, the satellite-inspector can easily combine the inspection functions with the functions of a fighter: went over, inspected, released a rocket, departed.

However, Mukhin stressed that fighter companions would be needed for Russia only in case of conflict, and there is enough work for inspectors in peacetime.
"Such a device needs the ability to actively maneuver between orbits, this is what the military is currently practicing during the tests," the expert said. "Having such a system will become a serious deterrent for potential opponents." They will know that the Russian Federation can check whether the functionality of their devices corresponds to the claimed device.

The idea to create fighter satellites was born even in times of confrontation between the US and the USSR. For example, in the USSR there was an IP program - "Fighter satellites." Its task was to disable the US missile warning system during the threatened period of spacecraft. Then everything rested on the price of IP devices: they cost more than the object of impact. Now with the advent of technology to produce low-cost compact spacecraft, the situation can radically change.

So the only news is that the Russian MoD acknowledged some details already known from TLEs for weeks.

Confusing statement from the Ministry of Defense on the Kosmos-2519 mission today (as quoted by TASS) :

http://tass.ru/armiya-i-opk/4686774

(my quick translation)

"According to [the Ministry of Defense] a satellite-platform was launched from Plesetsk on 23 June 2017 in the interests of the Ministry of Defense to conduct a scientific experiment to study a Russian satellite with the help of a small satellite launched from this platform.

Today, in the next step of the experiment, a satellite inspector was detached from the small satellite. The inspector is capable of diagnosing the technical condition of a/the (?) Russian satellite from the closest possible distance using special equipment.  The obtained information will be sent to Earth for detailed analysis and to decide whether the observed satellite will be restored to working order".

Literally interpreted, this would suggest that the object separated from Kosmos-2519 on 23 August (later called Kosmos-2521) has now itself deployed an object, but I wonder if TASS somehow got the wording wrong. Perhaps Kosmos-2521 returned to the mother satellite and has now been separated for the second time.

It's also not clear what satellite is going to be inspected this time. Since Russian has no articles, the report could be referring to either the same object observed earlier by the "small satellite" or another one. The satellite inspected earlier presumably was the Kosmos-2519 mother satellite itself. Now the target appears to be a satellite that has malfunctioned (or are they talking about a simulated observation of a malfunctioning satellite?). Many unanswered questions... 

Just wondering : is Cosmos-2486/Persona-2 still anywhere in the neighborhood?

A new piece of debris, 2017-037E, has been cataloogued from the launch in the last 24 hours.

The orbital data for the objects still in orbit for this launch are (catnum, epoch, inclination deg, orbital period min, perigee and apogee km and argument of perigee deg):-

42798     2017 Oct 30.895    97.91       97.91      650       667    185
42800     2017 Oct 30.786    98.04       93.57      284       615    339
42919     2017 Oct 30.759    97.91       97.91      651       667    185
42986     2017 Oct 31.089    97.88       96.88      554       664    215


Cosmos 2486 was never really close to Cosmos 2519/2521: their orbital planes were close but neither satellite never got physically close to the Kvarts satellite.

No. 8120 does not seem to be 14F150 no. 2.
Rather no. 1.
