preface
With the continuous popularity of mobile phone technology, positioning is increasingly needed in the process of people's travel, but when it comes to positioning systems, many people may think of GPS, which is also a global phenomenon of United States technology, but China's Beidou satellite is also very famous.
China and the United States have a certain "competition" in various fields, but the positioning system is very important, not only used in life, even if it is put on the battlefield is also a big advantage, many military fans also have some bold ideas, if China and the United States friction again, United States destroy China's Beidou satellite, how should China fight back?
The development of Chinese satellites
When it comes to GPS, many people may have a certain sense of experience, because these positioning systems will be used in the process of travel, and people will use GPS to lock the route in the process of driving, and it can be said that GPS is all over people's lives.
In fact, in 1973, the Ministry of National Defense of United States has begun to design and experiment with such a system, and such a global positioning system has also been developed by United States.
As early as the special period when GPS was popularized all over the world, some of China's cargo ships also used such positioning systems, but things changed in 1993, when a Chinese "Yinhe" was traveling on the high seas, and the positioning system at sea was very important to help ships identify the direction.
I just didn't expect that the GPS navigation at this time was turned off, which also caused the Galaxy to lose its direction at that time, and the United States did this, which also reminded China that the GPS of the United States was unreliable, and also made China work very hard to develop its own positioning system.
In 1994, China began research on satellite navigation systems, and named this research Beidou satellite navigation system, for which The Paper published a related article on September 9, 2024.
In the process of research and development, a three-step strategy was formulated, and the Beidou No. 1 system has been established in just a few years, and 12 years later, the Beidou No. 2 system has also been successfully born, and provides related services to the Asia-Pacific region.
In the eight years after the No. 2 system, the Beidou-3 system reappeared, and the No. 3 system had a wider radiation area and could provide services to the world, and the Beidou system did not stop after that.
In December 2023, China continued to launch the 57th and 58th Beidou navigation satellites by rocket at the Xichang Satellite Launch Center, and even in September this year, the 59th and 60th Beidou navigation satellites were successfully launched.
The continuous development of China's Beidou satellite system has also gained a foothold in the international environment, and like United States' GPS, it is a supplier recognized by the United Nations Satellite Navigation Committee, and such a breakthrough is undoubtedly a big step forward for China in new fields.
How strong is the United States
Although the GPS of United States has been developed before China, a network of 24 satellites has been established in the subsequent development, with some accurate positioning, the accuracy of United States GPS positioning can even reach 0.1 meters, with the output of signals in different frequency bands, and the coverage area is relatively large and extensive, which has a lot of use in the world.
Whether it is communication and navigation in people's daily life, or the positioning of smartphones now, GPS can be seen, but although China's Beidou system is not as early as the GPS of United States.
However, compared with the positioning system of United States, Beidou is not lost at all, Beidou system can obtain relevant positioning information through more than 30 satellites deployed around the world, but also with the continuous development of China's "Belt and Road" related policies, many areas can get some accurate positioning services with Beidou system.
In terms of quantity, China's Beidou system has more satellites than United States' GPS system, which shows that positioning will be more accurate and can provide better services on a global scale.
In addition to the most basic positioning services, China's Beidou can also be used in some special public safety fields, and when some major events occur, it can achieve emergency response, and can even communicate through some shorter messages, which are incomparable to United States' GPS.
Moreover, China's space technology is also constantly developing, and it has brought back lunar soil from the far side of the moon before, which is very helpful for human research in the future, which also shows that China's space strength has also made a qualitative leap.
However, it should be noted that satellites have a certain service life, and when the end of life will be regularly sent new satellites to replace, after understanding the strength of China's Beidou system, many people will also ask such questions, if China and United States in the event of a conflict, United States will destroy China's Beidou satellite, what should China do?
How to protect against war
In fact, in the process of Beidou satellite research and development, the United States has also used public opinion to render many times, and China.com published a related article on August 21, 2014, which mentioned the five major Chinese weapons that make United States afraid, including the Beidou satellite system.
However, while experts are studying the Beidou satellite system, they have also made relevant countermeasures in the face of potential "threats", and these four methods can also better help China deal with special situations and achieve better counterattacks.
Here we have to mention the specific classification of the Beidou satellite system, if in accordance with the Sino-US conflict, United States want to destroy the Beidou system, for this, in the study of the Beidou system, there are some electromagnetic protection technologies.
China Broadcasting Network released a related article on February 4, 2013, and also made relevant explanations for electromagnetic protection technology, in fact, it is in the face of those different frequency changes and extended technology, which can better form a layer of protection.
In addition to this layer of protection, there is also China's anti-satellite technology, which can paralyze and incapacitate enemy satellites, and wants to make Beidou satellites have better persistence.
It is even equipped with a series of rapid response devices, which can better be replaced in time in the event of damage to the satellite, also known as the Kuaizhou series of rockets.
In addition to being able to replace in time, the Kuaizhou series of rockets can also perform other tasks, these are the four magic weapons of the Beidou satellite system, I believe that under such layers of protection, it is not easy to hurt the Beidou satellite system, and China will also counterattack accordingly.
