In recent years, with the development of science and technology, various countries have launched a large number of artificial satellites into space. For example, Musk is expected to launch 42,000 Starlink satellites to provide satellite network for the earth. In recent years, China has launched a large number of satellites intensively to get rid of the restrictions of the United States in various fields.

However, the rise of China's artificial satellites has aroused high vigilance in the United States. It has conducted reconnaissance and monitoring of my country’s artificial satellites many times, seriously threatening the security of China’s satellites.

Recently, a U.S. commercial company revealed that the United States sent the spy satellite "America 270" to conduct reconnaissance on China's Test No. 12. The Test No. 12 satellite is China's two satellites in December 2021, namely Test No. 12. 01 star and Experiment 12 star 02.

When the American spy satellite maneuvered close to the Experimental Satellite No. 12 and prepared for reconnaissance, the Chinese Experimental Satellite No. 12 Satellite 01 and Satellite 02 performed an emergency maneuver in the opposite direction to avoid collision. Among them, China's experimental satellite No. 12 02 was forced to enter the sunshine area. The situation was suddenly reversed, and it became a Chinese satellite "monitoring" American spy satellites.

China’s test of satellite No. 12, an anti-reconnaissance measure, has aroused high dissatisfaction in the United States. The United States media claimed that the United States is worried that other countries have the ability to detect U.S. surveillance satellites and is worried that China will leak the secrets of U.S. surveillance satellites. This also made Chinese netizens very angry: American spy satellites provoked Chinese satellites first, how shameless!

US satellite is approaching for reconnaissance, what is its intention? Space mobility means cracking US reconnaissance

For a long time, the United States has been known as the world's police. Relying on its own technology and military, it "governs the sky, the earth, and the air." It can be said that it controls everything and dictates the world. In the space field, according to statistics, since 2014 to the present, U.S. spy satellites have carried out hundreds of maneuvers to conduct reconnaissance on satellites of other countries suspected of being threats.

What can US spy satellites detect when approaching satellite reconnaissance satellites of other countries? Due to the differences in the altitudes of satellites in various countries, if spy satellites want to perform reconnaissance missions on other satellites that need to be reconnoited, the spy satellites must maneuver over a wide range and get close to the satellite being reconnoited. When

is close to the satellite being detected, it intercepts the radio signal of the satellite being detected and obtains the data on the working of the satellite (since satellite encryption in various countries is relatively simple, the United States can easily decipher the data returned by the satellite. China's quantum satellite communication is currently still in trials stage, if quantum communication can be implemented, satellite communication data can be made more secure).

Nowadays, when quantum communication has not been implemented, the best way to crack the US reconnaissance satellite's reconnaissance of our country's satellite is through space maneuvering. Through rapid orbit changes or reverse maneuvers, we can quickly avoid spy satellites and disappear behind the spy satellites. in the field of vision.

"Starlink satellites" may be the biggest threat to space monitoring

In the field of space exploration, according to statistics, there are more than 4,800 satellites in normal operation around the world, including 2,944 in the United States, 169 in Russia, and more than 500 in China, respectively. Scientific satellites, technology test satellites, and application satellites.

However, the biggest threat in space may be commercial satellites. The number of Starlink satellites currently launched by the United States is as high as 2,232. It is reported that the Starlink satellite constellation has begun operating its satellite Internet service " Starlink " on aircraft, ships, RVs and other residential and commercial vehicles, allowing Starlink to expand broadband coverage to meet users' mobile connection needs.

In 2021, Starlink satellites approached the Chinese Space Station twice. In 2022, Starlink satellites provided reliable intelligence for the battlefield, making many countries feel the threat of Starlink satellites. Since the number of Starlink satellites is very large and the deployment range is very wide, the cost of intercepting satellite data from other countries may be the lowest.

Starlink satellites are relatively low-cost and have very wide coverage. They can realize multi-point linkage reconnaissance for space reconnaissance, achieve precise positioning of all space satellites, and perform dangerous actions such as data interception.

concluded that with the development of science and technology, artificial satellites provide more precise services to mankind, and everyone has enjoyed the convenience brought by the services. In the future, artificial satellite data security and space security will be the focus of joint research by scientists from all over the world.
