Chinese spacecraft removes 'decommissioned' satellite from geostationary orbit

In the United States, it is assumed that China has created a tug to work in space. This is evidenced by the fact that the Chinese spacecraft Shijian-21 removed the "decommissioned" navigation satellite Compass G2 from geostationary orbit.

This is evidenced by the results of space monitoring made by the American company ExoAnalytic Solutions.

Observations showed that Shijian-22 (SJ-21) disappeared from view for several days on 21 January as it approached Compass G2. Its disappearance is explained by the fact that the docking of the two devices took place in the daytime, when the telescopes did not receive an image. But then they managed to fix the very moment of undocking, when the “dead” satellite had already been towed to the so-called burial orbit.

After completing its mission, the SJ-21 returned to geostationary orbit.

An analysis of these maneuvers led observers to believe that the purpose of the Chinese apparatus is to clear the "densely populated" geostationary orbit from space debris in order to clear the way for other satellites.

A geostationary orbit is one in which space objects move in sync with the rotation of the Earth. Thus, they are constantly above the same point on the surface of the planet. They turn on their engines to change location.

In the West, statements have appeared that China can use its spacecraft to “influence” the satellites of other countries, including the United States. In China itself, these statements have not yet been commented on.

If they (adversaries) interfere with the Chinese on earth, then the Chinese will shoot their satellites in space ...
It should be noted that navigation satellites hang at altitudes of 20 km. And you can’t land them with a rocket from the ground ...

It is not clear, in general, how the stations for tracking dangerous situations in orbit will help GLONASS. Unless they warn of a possible collision with other satellites. But this, most likely, is done by the GLONASS network correction station itself.

By the way, in March, according to the plan, if they don’t replay the fact, another satellite flies - the last of the M series.

In the monitoring system of ground objects and its network of satellites. GLONASS does not track other space objects. Unlike the same ASPOS OKP, which monitors many constellations of satellites, including GLONASS.

Satellites communicate with each other and with the ground station, determining their coordinates in space and time

The GLONASS/GPS receiver receives signals from the nearest satellites, records the time of receipt of each signal and its content, calculates the distance to the satellites and, based on these data, determines its location in three coordinates - longitude, latitude and height above sea level. To determine the coordinates, the receiver must receive a signal from at least four satellites and calculate the distances to them.

Thus, GLONASS is not used for space tracking. This is the task of ASPOS OKP. Contrary to your statement:

The article only dreams that GLONASS will determine the trajectory of the orbits of the spacecraft.

Yes, many of our spacecraft, carriers, upper stages already have GLONASS receivers as part of their onboard equipment. But so far they are either auxiliary means, or are used as part of the payload. Until now, for carrying out trajectory measurements, for determining the orbits of near-Earth spacecraft, for synchronization, in most cases, ground-based means of the command-measuring complex are used, many of which have long exhausted their resources. In addition, the measuring instruments are located on the territory of the Russian Federation, which does not allow for global coverage of the entire trajectory of spacecraft, which affects the accuracy of the orbit.

The energy industry is different, in order to get to the geostationary orbit you need much more fuel + oxidizer.
What different countries experienced in packets destroying satellites, then it was about fairly close orbits. Russia tested at a height comparable in height to the ISS, because of which the west raised a howl, although the orbits were different.
Those. tested for altitudes up to 300 - 400 km.

anti-satellite missiles are designed to destroy spy satellites, RTR satellites, etc. in LEO, that is, several hundred kilometers. No rocket will reach geostationary ones.

I probably don’t understand something, but if the satellite delivered the rocket there, then the rocket can remove this satellite. I'm not talking about, of course, that the rocket will fly all "20kkm" without stopping.

I did not say that a Proton should be fired at each satellite.
I wrote "conditional Proton", meaning that you need to have a solution, for example, your own light cleaning satellites.
Of course, you don’t need to shoot down two-kopeck garbage with a rocket for lam bucks.
The economy is not our forte now.

[Bratkov Oleg]

They do not understand that a satellite is equipment that does some work, for a long time, and has a large mass, including a supply of fuel. And the interceptor only needs to fly to the desired satellite, and poke into it, and then it doesn’t have to correct the orbit for years, and there’s no need to relay something, or photograph, or whatever ... The mass of the interceptor is less, and the rocket delivering the interceptor to satellite, less. "Proton", probably, from half a hundred interceptors to the geostationary will deliver, to the horror of the liberals ...

Yes, he screwed it up. One Soyuz-2 is enough with the Fregat missile launcher and a payload with electric propulsion propulsion engines and a recoilless gun of the Nudelman system, which was on Salyut. And you can shoot satellites like in a shooting range - they are there on the GSO in a row.

that is, any rocket.
Although the A135 - if only it flew.
And, secondly: this did not mean the direct impact of the missile on the target.

At the meeting there will be no landing. There will be a new pile of debris (space debris) that interferes with the use of outer space. Orbits are little predictable, threats to others are great. Shooting down makes sense only in wartime. And so - it will burn in the dense layers of the atmosphere.

the purpose of the Chinese apparatus is to clear the "densely populated" geostationary orbit from space debris

That's interesting. I remember as a child my house was always clean. But when mom started cleaning the apartment anyway on Saturday, dad went to the garage or to the country house, and we, the children, shook carpets on the street, moved furniture, carried chairs and tables from room to room. And if they didn’t do anything and got in the way under their feet, then they got a wet rag on the ass and again connected to the process of cleaning up.
However, in space, orbital debris does not go anywhere, it only accumulates.
And... this is what cleaning will look like when its day is sure to come... very interesting ...

A very useful companion. It is necessary to create an international team with similar devices from different countries in order to consistently remove spent or faulty satellites from orbit.

If, for a specific task, a geostationary satellite is "reparked" into a burial orbit, it is obvious that it is just a little lower.
The best option is to use the orbit correction engines of the satellite itself, you just need to pump a little more fuel into it. At the end of the term, it will simply lower its orbit and turn off.

A tug is also needed, but it's like an emergency tow truck. And cooperation is needed with understandable mutual settlements, if such a tow truck is located in some sector, then it could not only remove Chinese garbage from orbit, but also other space powers at the same time, it is beneficial for everyone.

This is if there is a connection with it and its electronics are functioning.
But satellites often "die" in orbit. Or they don't get in touch from the start.

In the United States, it is assumed that China has created a tug to work in space. This is evidenced by the fact that the Chinese spacecraft Shijian-21 (Beidou) removed the "decommissioned" navigation satellite Compass G2 from geostationary orbit

we also wanted to make an apparatus for this purpose.

The Federal Space Program of Russia for 2016-2025 includes the creation by 2025 of a "cleaner" of garbage from geostationary orbits

The device was called "Liquidator", the development was entrusted to TsNIIMash, the satellite was supposed to fly into orbit in 2025. According to the latest information, due to budget cuts, the program is suspended indefinitely (although not closed)

Chinese spacecraft removes 'decommissioned' satellite from geostationary orbit

So Russia is also working on it.

As told to Gazeta.Ru at the head scientific institute of Roscosmos JSC TsNIIMash, the corporation is considering several options for cleaning robots. For example, the Moscow Aviation Institute (MAI) has already developed projects for a service spacecraft “with an ion beam injection system”, which will “push” space debris from the protected area of ​​the geostationary orbit (GSO) to the “cemetery orbit” (located above the GSO by 200 -300 km)

Side to China. Recently, the James Webb telescope, almost a month after its launch, successfully completed its flight to the second Lagrange point in the Sun-Earth system and entered a working orbit around it. This is interesting, because science and knowledge of the universe.

Yes? Then the Spektr-RG telescope, which, by the way, has been flying at this second Lagrange point in the Sun-Earth system for three years now, recently witnessed the birth of a relativistic compact object as a result of the explosion of a massive star. That's interesting.

[Esoteric]

Naturally, this is also interesting. And I know about it. I consider Einstein the destroyer of scientific and technological development, he took away our stars, if he had not happened, science would have taken a different path, and it is quite possible that worlds from other Suns would have been colonized.
And the Webb telescope is the greatest achievement. As they say - "Good luck".

There is no great achievement yet. Is it that of those who built it and started it up, or those who drool on the net at any mention of it. There, this super-expensive long-term construction has just reached orbit. Achievements have him if and will then.

Here Hubble is an achievement. Or RadioAstron. As well as other astrophysical telescopes that are currently working.

I was more puzzled: the burial orbit! Yoshkin cat, mankind will organize a dump everywhere!
