Recently, China’s aerospace has made a number of breakthroughs, the most interesting of which was on September 15, when my country used the Long March 11 carrier rocket to successfully send nine "Jilin-1" satellites into it at the same time. Sun synchronous orbit. For this satellite launch mission, I believe that many people do not have much expectation after being excited. After all, our country has realized the dream of multiple stars with one stone a few years ago. The reason why the "Jilin No. 1" satellite has made a global sensation this time is because Changguang Satellite Company recently exposed a video. The true strength of

has been exposed, and Jilin-1 has attracted global attention. In the video of
a fighter is flying at high speed. Although the flight trajectory of the fighter is disturbed by a thick layer of cloud and fog, the "Jilin-1" satellite still flies steadily. The fighters in China were followed and monitored. After the video was released, some netizens judged from the vague outline that this is a US military F-22 stealth fighter, because its inverted trapezoidal main wing and horizontal tail are highly similar to the US F-22.

is the most advanced fifth-generation aircraft in the world. The F-22 fighter of the U.S. Army has excellent stealth capabilities. It is difficult for ordinary fire control radars to detect its presence. Although the long-range warning radar can detect the traces of stealth fighters, Because the accuracy is too low, the missile cannot be guided to attack it. The "Jilin No. 1" satellite not only found the F-22, but also tracked live shooting throughout the entire process, which provided countries around the world with a new idea of anti-stealth fighters.

It is understood that the "Jilin One" satellite is generally deployed in a sun-synchronous orbit 535 kilometers from the ground. The U.S. F-22 stealth fighter has a flying altitude of 10,000 to 20,000 meters, which means that the distance between the "Jilin One" satellite and the F-22 fighter is at least 500 kilometers. At such a long distance, the "Jilin No. 1" satellite can still identify and track, which also makes countries around the world realize the practical significance of optical remote sensing satellites. After the video was exposed, the Royal Academy said in amazement: The air defense system currently equipped in China is sufficient to weaken the combat effectiveness of the US F-22 and F-35. With the development of China's air defense technology, it is likely to overtake the United States and Russia in one fell swoop.

surprised! "Jilin One" is not used in the military field?
In fact, the main task of the "Jilin One" optical remote sensing satellite is to monitor and analyze my country's agricultural and forestry resources. Because of the high resolution of this kind of satellite, which can reach 0.5-1 meters, it is often used in land surveying and mapping, urban construction, and transportation planning.

According to the plan, Changguang Satellite plans to launch a total of 138 Jilin satellites by 2030. By then, the Jilin-1 constellation will be able to detect any point on the earth every ten minutes, even if it is flying extremely fast. The fifth-generation sonic aircraft cannot escape the "golden eyes" of the "Jilin-1" satellite. In response to this extremely powerful detection capability, some netizens claimed that the "Jilin No. 1" had opened a "sky eye."

How strong is the "Jilin No. 1" with a "God Perspective"?
It is understood that this is not the first time that "Jilin One" has discovered a military target. Earlier, the "Jilin-1" satellite broadcast live broadcast of the entire process of the US aircraft carrier's arrival in the port, and also "live broadcast" the entire process of the US military P-8A maritime patrol plane taking off at the airport. Because this kind of satellite can continuously shoot video images with an accuracy of less than 1 meter, the "Jilin No. 1" undoubtedly opens up a "God's perspective" for enemy targets, and can monitor their every move during a certain period of time.

However, because the current number of "Jilin-1" satellites is relatively small, and the time to "revisit" the target is relatively long, it is impossible to monitor the target's whereabouts around the clock, which leaves time for the enemy target to escape. However, when the number of satellites increases to 138, this problem will be completely resolved.

All in all, the "Jilin Satellite" detected a suspected US F-22 aircraft, which is of great significance for future research on anti-stealth fighter equipment. With the development of science and technology, the future is likely to break the US military "stealth myth", so that the US military F-22 and F-35 have nowhere to hide, let us wait and see.

Stop posting useless sh!t from a useless fanboy website.

Consider this a formal warning. The next time you post a poor quality article like this you will receive a one month warning ban.

Even though certain Chinese RM and SAR satellites may have some useful ability to detect and track aircraft with the appropriate software doing the work, they can't do much to guide missiles towards stealth targets and vectoring in fighters to intercept is next to useless since many radar systems can already give you the general direction if the ranges are close enough. You're still going to be targeted and shot at by the F-22s and F-35s. These just give us a hint on how CBGs can be located and tracked using similar technologies.

More info. Secretive, eh?

Typical sentimental.:rolleyes: There was a NOTAM notification on 26th, one day before the launch, just like the "not so secretive" Jilin-1 Gaofen launch "flight path going directly over Taiwan" on 14th. BTW, what does "flight path over Taiwan" have anything to to with satellite launches? Put aside sovereignty aside, rocket over Taiwan is outside of atmosphere that belongs to nobody or everybody. Besides, to reach an specific orbit, the launch path is fixed, there is no choice regardless.

Peacock experimental reusable rocket. It was apparently involved in testing new intelligent flight control software. Because my technical Chinese in this area is deficient, I'm not able to competently translate the text below. Our Chinese-speaking members, please help with a translation.
