China is preparing anti-satellite weapons. The US is very concerned

Back in October last year, American media reported that China was preparing a test of a new Dong Ning-2 anti-satellite missile (DN-2) with a kinetic interceptor, but the test was postponed.

4 in January, the American organization "Union of Concerned Scientists" wrote in its blog that in the near future, China will report on the launch of this rocket. The Pentagon expressed "very great concern" about the possible testing of the anti-satellite weapons.

In January, 2007, China conducted the first test of an anti-satellite rocket, which ended with the destruction of an exhausted meteorological satellite resource at an altitude of 558 km. Thousands of fragments of this device are still in orbit, representing a threat to manned spacecraft and satellites. The second test of the missile, which received the western designation SC-19 (developed on the basis of a ballistic missile KT-2), was conducted in January 2010 year. The test had a dual purpose - "testing anti-satellite and anti-missile capabilities."

According to US forecasts, China may experience DN-2 for several weeks. The height of the destruction of the target is estimated to be over 22 thousand kilometers. The Pentagon made a statement saying that "we are closely following the development of the Chinese armed forces and call on the authorities of this country to show greater transparency regarding their capabilities and intentions." China is developing other technologies, including the creation of electronic and electromagnetic interference to the enemy satellite constellation and the use of a laser beam to hit orbiters.

Pupil is not clear however :)
GPS satellites fly at an altitude of 4000 km, they would be shot down, but get to the moon’s orbit, this is 4 days of flight))))

There will be just GPS satellites knocking down.

This is exactly what America is worried about, the satellites are hitting it and all their high-precision crap will lose relevance. The soldiers will be guided by paper maps of the mid-20th century.

Yeah, China has gained such momentum that it’s hard to stop it ... SUSTAINABLE will have to reckon with this force.
Just knock down your satellite with the already known parameters of its movement is not a trivial matter, but an alien will be even more difficult. And pin-dos understand this perfectly, but everything is exactly scat ...)))))))))))))) Here it is a projection of force in action! Opportunities are still illusory, and already everyone around is afraid. ))))))))))))))))

IMHO, China reminds me of Germany before World War II: the same unbelievable foreign policy ambitions, arrogance, breakthrough achievements in the military industry and a focus on world domination. Angry, insidious and hungry tigris!

The USA became like a lion in a pride: "it will be necessary - I will take you all!" And the fact that nearby bears, tigers and jackals have picked up silushki somehow loses sight of!

[papik09]

And China, like that three-month-old teddy bear in the joke: "And even though I am three months old, I give everyone pills, it won't be enough."

[Lord of the Sith]

I will add "and the fact that the lion periodically needs to rest and sleep", and then suddenly do not climb the previously offended enemies and attack when the lion is sleeping - read the crisis will begin.

The problem from the category of solvable. The orbits are now easy to calculate, for geostationary even easier.

[viruskvartirus]

Solvable is solvable but not simple, we need a space monitoring system, and it still needs to be created ... rockets are not everything ...

[neri73-r]

Who told you that? The coordinates of all satellites are known and tracked, respectively, the trajectory of its movement is also known!

[Narkom]

And they can, on paper then?

I think 90% minimum, all amer equipment works with info from satellites. A blind army does not know where to go and where to shoot.

[alexng]

For this reason, the American army is the most worthless with any respectable opponent, since it is the most vulnerable army in the world. All their steepness is manifested only in small defenseless countries, and even then not always. They had fun with Iran in full and they are unlikely to go there already.

Alexander Romanov,

Attention! You do not have permission to view hidden text.

But this is something they probably already forgot. The habit of electronic assistants is corrupting the mind.

[Lord of the Sith]

Naturally, they have the entire military machine delivered on satellites. And drones and the Air Force, and special operations and guidance of the Tomahawks, and a bunch of all kinds of positioning troops.

Without satellites they’ll be afraid to cover their own with an artillery strike.

[Tjumenec72]

Concern rather - with the possibility of creating a PLANNED GARBAGE in orbit. So it can complicate the work of the satellite constellation in a relatively non-hostile way.
Do not you consider the option when China really encroaches on the yanker satellite? !!! - THIS IS THE MOST DECLARATION OF WAR

[SergeySK]

Login_Off,

Shooting down a GPS satellite is problematic enough! These satellites are not geostationary!

They also cannot shoot down geostationary reconnaissance satellites (about 35 thousand km)!

US concerns are more likely to come than reality!

To shoot down satellites it is necessary to be at war who will let them make launches in such conditions ????

The launch of a ballistic missile in a CONFLICT state is essentially the beginning of a nuclear war! ! ! !

[mar.tira]

America, with its imperial ambitions, willfully doesn’t force the people living on Earth to look for ways to protect themselves from it. So you shouldn’t be surprised. Yes, you have a lot of fat! Have seen enough, both in Iraq and Yugoslavia! And they made conclusions (correct) !!

[tor11121]

Yes, here it’s not only probably that the USA should have a worried look. It’s not a secret for anyone that a nuclear shield without satellites is not a shield at all. not for the Americans, after all, the Chinese have created a huge land army.

[Trailer]

So I am also worried about Mongolia!

[Alyans]

At one time, England almost destroyed China. The USA and the USSR decided to raise him from his knees. And everyone knew perfectly well about Chinese ambitions. Now we are reaping the benefits ....

[Averias]

Good morning everyone! If my memory serves me, our demonstrating the aerobatics "Cobra" (another air exhibition) on one of the "SU" aircraft, as if casually said - from such a position the aircraft is capable of shooting down and deflecting satellites from orbit, there was a horror of noise in the Pentagon , but it was about ten years ago. At first, the Pentagon didn’t believe it and said that we were wishful thinking, but when we conducted a firing practice and rejected the satellite from orbit with a rocket with a simple blank, they went nuts. And they tell us about China , hehe, see the root (K.Prutkov).

[Tjumenec72]

Shaw for the blockbuster)))

[Trailer]

I’m even afraid to ask - is this an inaccuracy of the author, or for what 22 thousands of kilometers will he find a satellite?

[Averias]

But what about the Moon, the most that neither is a satellite, and what size, you just can't miss. Well, think "a little further", but what a scope

[basal]

I was also interested. If there is a satellite straying, how can a missile be guided at such a distance? Maybe it was not the altitude that was meant, but the flight range? Although too much ....

Low Orbit Satellites (LEO)
The satellites of low orbit are usually considered satellites with altitudes from 160 km to 2000 km above the Earth's surface [. Such orbits (and satellites) in the English language literature are called LEO (from the English. "Low Earth Orbit"). LEO orbits are subject to maximum perturbations from the Earth's gravitational field and its upper atmosphere. The angular velocity of LEO satellites is maximum - from 0,2 ° / s to 2,8 ° / s, orbital periods from 87,6 minutes to 127 minutes.

Medium Orbit Satellites (MEO)
Medium-orbit satellites (SOS (Russian), or "MEO" - from the English. "Medium Earth Orbit") are usually satellites with altitudes from 2000 km to 35786 km above the surface of the Earth. The lower limit is determined by the LEO boundary and the upper limit by the geostationary satellite orbit. This zone is mainly "populated" by navigation satellites (the "NAVSTAR" satellites of the "GPS" systems fly at an altitude of 20200 km], "GLONASS" - at an altitude of 19100 km and the bonds that cover the poles of the Earth]. The circulation period is from 127 minutes to 24 hours. Angular velocity - units and fractions of angular minute per second.

Geostationary and geosynchronous satellite orbits
Geostationary satellites (GSS (Russian), or "GSO" - from the English. "Geosynchronous Orbit") are satellites with a period of revolution around the Earth, equal to the sidereal (sidereal) day - 23h 56m 4,09s. If the inclination "i" of the orbit is zero, then such orbits are called geostationary Geostationary satellites fly at an altitude of 35786 km above the surface of the Earth. Because their period of revolution coincides with the period of revolution of the Earth around its axis, then such satellites "hang" in the sky in one place. If inclination "i" is not equal to zero, then such satellites are called geosynchronous ... In reality, many geostationary satellites have a slight inclination and are subject to disturbances from the Moon and the Sun, in connection with which they describe figures in the sky in the form of "eight", elongated in the north-south direction.

High Orbit Satellites (HEO)
High Earth Orbit satellites (VOS (Russian), or "HEO" - from the English. "High Earth Orbit") are satellites, reaching heights of more than 35786 km above the surface of the earth, i.e. flying above geostationary satellites.
An example of satellites of the series "Lightning" and "Meridian"

[Ascetic]

There is still a separate class of orbits -burial orbits specially designed to remove satellites that have failed to reduce the likelihood of a collision with working satellites and to free up space for a new satellite. For a GSS, the orbit of a burial site is considered to be an orbit 200 km higher than the orbit of the GSS itself. For each GSS satellite, the burial orbit calculated separately
Onboard low-orbiting satellites with nuclear reactors they have a disposal orbit altitude of the order of 1000 km, where the active zone of a nuclear reactor is transferred after the end of its operation.

[Tjumenec72]

Apparently confused at zero (media most likely)

[erased]

We also need to be able to knock down satellites. as well as neutralize their work, as well as the entire navigation system.
there is such an option - a nuclear explosion, but it is quite dangerous. Something simpler is needed. And then NATO will wash ...

The photograph shows the head of a promising antisatellite rocket equipped with its own marching engine (holes for shunting micromotors are visible in the bow for a more accurate exit to the target area in outer space).

By the way, in January 2007, the Chinese successfully tested the kinetic interceptor of the spacecraft launched using the BR. China has successfully destroyed its own, already decommissioned meteorological satellite Feng Yun 1C (FY-1C), which served as a target. In this case, the satellite was located on an orbit about 850 km high.
Destruction of satellite FY-1C carried out according to the direct interception scheme during a flight over the territory of China west of the Xichang training ground. As a result of the destruction of the satellite, a cloud was formed in orbit containing more than 40 thousand fragments 1-10 cm in size and about 2 million particles of smaller diameter.
To date, 4 U.S. optical surveillance satellites KH-12, four Lacrosse radar reconnaissance satellites (they use oblique orbits) and at least 4 operational DMSP Block-5D2 military weather satellites are in Chinese orbit. All in all, in the world low polar orbits operated by about 125 spacecraft.. So far, only three countries can boast the existence of existing anti-satellite systems - this is Russia, the USA and China.
Similar systems are now actively engaged in India, Israel, Japan and Taiwan.

The Indian Ministry of Defense has begun development and will soon begin testing a new "exo-atmospheric" spacecraft and lasers for it, capable of destroying satellites operating in orbit.
According to V.K. Sarashvat, Director General of the Defense Research and Development Organization, which is part of the Ministry of Defense of India, unlike all previously shown samples of weapons, Indian anti-satellite weapons will have an advanced laser guidance system that will allow the satellite not only to be seen by the laser beam, but also by the installation operator and get the primary data about the satellite even before it is destroyed.

China is accumulating strength and improving weapons, and no one knows against whom it will be directed.

[gregor6549]

Absolutely right. In light of this, it is not clear where this wild "enthusiasm" about the arms race in China and the naive belief that this race is directed against the United States comes from. There was already a moment in the history of the USSR when there was nothing left before the war with China. But then the Chinese Armed Forces were much weaker than the USSR Armed Forces. Now the situation is completely different. all the more so as all the republics of the former USSR tried to sell to China everything it wanted to buy. And from the point of view of logic, China has nothing especially to catch in America. It's too far away. And here is Russia, with vast and almost undeveloped territories and resources at hand. So the maximum that can be expected from China in relation to the United States is to oust their AUG from the ocean zone, which China considers its own. But what can be expected from China regarding Russia is a big question.

Reminds a situation before the Second World War. The USSR was also sure that Hitler would not attack and supplied various materials and foodstuffs to Germany. But Hitler accumulated strength and attacked, where is the guarantee that China does not go in the same direction

The problem is that restoring the space constellation is a matter of many days or months. In a war, no one will give you this time. The first to destroy enemy satellites, gets a huge advantage

In my humble opinion, NO. For, without our contribution, this thing is unlikely to be done with them ...
It’s just that for some reason our specialists are not attempting to encroach on the production of RSD, in fact, it is the carrier of the anti-satellite. And the Chinese produce RSD ... like Pioneer We are bound by the Treaty and the lack of capacity ...
Therefore, long live Russian-Chinese cooperation in space exploration!
