For decades, with the continuous development of China's aerospace technology, navigation technology has also been continuously developed. Today, China's Beidou navigation technology has ranked among the world's advanced. However, for the Beidou navigation technology, presumably everyone's common feeling is: only hear its name, not see its body.
In fact, we have turned back the clock to the beginning of last year, when our country was in the stage of an outbreak. As there were not enough hospital beds, new hospitals needed to be built. At this critical time, the Beidou system rushed to the rescue, not only using Beidou's high-precision technology to complete most of the measurement work at one time, saving a lot of time for the construction of the hospital, but also escorting the rapid construction of Vulcan Mountain and Leishen Mountain. Obviously, the Beidou system has not only helped China complete the impossible challenge, but also won time for fighting the epidemic.
I have to sigh that from the 90s of the last century to the present, from scratch, from weak to strong, the Beidou system can have such brilliant achievements, which is really remarkable. However, behind the glory of the Beidou system, it carries many setbacks and challenges, and even encounters major problems and faces the test of life and death.
Presumably seeing this, everyone must be very curious, what major blows has the Beidou system experienced? And who will be saved? If you want to understand this problem, you have to start with our Beidou system.
In fact, the construction of our Beidou system is divided into three steps: first try it, expand it to the Asia-Pacific region, and face the world, corresponding to Beidou-1, Beidou-2 and Beidou-3 respectively. When the Beidou system encountered major problems, it was in the second step.
Due to the late start, when China developed Beidou, Western countries have already made great achievements, so there is not much time and resources left for China. But even so, these countries, for the sake of their so-called hegemony, are obstructing it and trying to limit the development of our navigation technology. Not only that, but at the World Radiocommunication Conference in 2000, the topic of "removing certain frequencies" appeared, and it was obvious that the intention of this move was obvious: to strangle the Beidou system in the cradle.
However, with the help of Russia, China's Beidou system was saved, and the conspiracy of these countries did not succeed. But this also sounded the alarm for our country, the ceremony after the end of the conference, we immediately declared the frequency, fortunately the declaration was successful, the Beidou system was also preserved.
However, according to the relevant regulations at that time, once the declaration was successful, it was necessary to launch satellites within 7 years to seize the frequency. In this way, while we successfully declared, we also ushered in a huge challenge for ourselves. However, in this case, a navigation power began to fall into the ground: high-power electromagnetic interference on the first star of Beidou-2, which had just entered orbit. After the Beidou-2 system was electromagnetically interfered with, the success rate of its signal reception was seriously affected.
If this problem is not properly solved, the construction of the Beidou system will be difficult to carry out smoothly, and even the previous efforts will be wasted. I have to say that the navigation power is really fierce enough, after all, the Beidou system after being interfered with is about to fall into a situation of "passive bankruptcy".
However, Chinese has always been a strong force in his bones, rather than waiting for "passive bankruptcy", it is better to take the initiative to fight. The crisis was resolved by Wang Feixue, an aerospace expert who was in danger, who led his team to make a military order and only took 70 days to fight a beautiful turnaround battle. In addition, the satellite payload developed by him and his team has increased the interference capacity of the Beidou system by 1,000 times.
It is worth noting that this is not the first time that Wang Feixue has saved the Beidou system. In the 90s of last century, the Beidou system had just been established, it encountered the problem of "fast catching sperm heel", when everyone was at a loss, Wang Feixue, who was studying for a doctorate, took the initiative to ask for help, and finally made the problem solved.
Of course, Wang Feixue's credit is not limited to saving Beidou from water and fire twice, but also in the fact that he and his team have always struggled at the forefront of China's navigation cause. On the one hand, he led the team to overcome a series of key technologies such as fast capture of navigation signals, short-term high-progress ranging, and strong anti-interference, making China always in the world's leading position in this regard. On the other hand, he and his team have also developed China's first portable user machine, the world's leading detection receiver and precision ranging code module and other equipment. It is no exaggeration to say that Wang Feixue has made great contributions to China's Beidou navigation system.
As the saying goes, ten years to sharpen a sword. Beidou people like Wang Feixue are firmly forging ahead step by step with a sense of mission, and have been working hard for decades to sharpen the sword of Beidou. However, it has to be said that such a spirit of study and faith in the motherland's space navigation technology are also worth learning.
