Chapter 1465 Conduct an anti-satellite test

    Of course, this kind of simplicity is only in the eyes of Europeans.

    In fact, the issue of navigation satellites has been discussed several times in China, and one of the discussions was even personally promoted by Zhuang Jianye. This was how two paths, international cooperation and independence, were finally formed.

    However, due to various reasons, international cooperation still has the upper hand, and therefore receives more financial support. The reason for this is that many people in China have particularly beautiful illusions about Europe. They feel that after the end of the Cold War, with the integration of Europe  With the deepening of the crisis, especially the formal issuance of the euro, Europe will inevitably become the other pole competing with the United States, the only superpower.

    With the formation of a unified market and a unified currency, Europe is bound to usher in a wave of strong development relying on the foundation accumulated since the Industrial Revolution.

    At this time, riding on the rapid development of Europe is a good choice for China today.

    On the other hand, and the most important reason is that the country still needs to rely on imports from developed countries for key components of navigation satellites, such as the most critical atomic clock. Although the country has relevant research and development capabilities, there are obvious deficiencies.

    Either the accuracy is guaranteed, but the overall mass is as high as more than 300 kilograms; or the volume can be controlled below 40 kilograms, but the timing accuracy is poor.

    In this regard, Europe is able to control the quality of atomic clocks under 20 kilograms, power consumption within 30 watts, and lifespan of at least 5 years while ensuring accuracy.

    This is not very friendly to satellite platforms with limited space and limited power consumption.

    And this is not the limit of European atomic clocks. The next-generation cesium atomic clock being developed by the European Precision Instruments Group in Switzerland can not only control the timing accuracy to a frequency stability of 5 parts per trillion, but also have a 24-hour drift rate of less than one part per trillion.  1, thereby giving the "Galileo" navigation satellite a navigation accuracy of 10 meters.

    That¡¯s all. The key is that the cesium atomic clock developed in Europe has reached the chip level. The overall mass is only 2.2 kilograms and the thickness is less than 25mm.

    Thanks to the breakthrough of this cesium atomic clock, the future "Galileo" navigation satellite, like the GPS3 that the United States is preparing to launch, will completely eliminate the bulky hydrogen atomic clock and instead use rubidium atomic clocks and cesium atomic clocks to back up each other.  Navigation capability with maximum accuracy of less than one meter, making it the most advanced navigation system in the world.

    "Compared with the glamorous European atomic clock, the difference between domestic products is that of a grass chicken and a phoenix. The gap is not as big as usual.

    Because of this, even those who are staunchly independent are not opposed to foreign cooperation. After all, learning advanced foreign technologies is also a hidden attribute of foreign cooperation. Since China is not doing well enough in some aspects, we must learn with humility. As for  Whether you get pregnant after just one look, after a few looks, or if you simply devote yourself to racing and get pregnant, it all depends on your personal ability.

    However, whether it is the international cooperation faction or the independent faction, the idea of ??relying on external forces to achieve its own development is completely shattered at this moment, because the head of the headquarters has made it clear that the cooperation plan with Europe exists in name only.

    ¡­¡­

    ¡°I won¡¯t go into specific nonsense about international politics and geostrategy, but will emphasize three points. First, the money we invested was wasted; second, we learned nothing; third, the International Telecommunications Union  The ruling was very unfavorable to us, so I came here today just to hear from you, whether we can put a fully mature navigation satellite into the sky by April 2007 and send out the navigation frequency approved by the International Telecommunications Union?"

    The head of the headquarters was as clean and tidy as ever, but as soon as he said this, everyone present showed surprise. It is now December 2006, and it is still the 28th. Rounding it off, it is 2007.

    Where are the mature next-generation navigation satellites? People in the aerospace industry still don¡¯t know. How can it be possible to complete this task in more than three months?

    Even if we take 10,000 steps back, we now have mature navigation satellites in our hands. Space launches are no longer a piece of cake. We need to calculate window periods, orbits, fixed angles, coordinate ground and sea measurement and control, and put them together piecemeal. There is no one or two.  The month does not come down at all, so more than three months is not enough time no matter how you calculate it.

    However, if mature navigation satellites are not put into designated orbits before April 2007 and navigation signals are launched in accordance with the regulations of the International Telecommunications Union, then the navigation frequency bands previously applied for domestically will be completely scrapped, and Europeans will eat them up.  There is only a few tenths of an error between the two parties. A slight change in the demodulator can completely cover the domestic frequency. By then, the country will not have the chance to use it again.

    Of course, some people will ask at this time, hasn¡¯t China already launched experimental navigation satellites, so why hasn¡¯t it occupied its own frequency? EuropeA human-launched navigation experiment satellite will suffice?

    Just take a look at the composition of the Bureau of the International Telecommunication Union. There is one American, two French, two British, one German, one Spanish and a black uncle from Gabon, Africa.

    ??As long as you are not blind, you will know that this combination is an old double standard.

    This is indeed the case. Domestic navigation satellites have already been equipped with 4 satellites. However, the Bureau of the International Telecommunications Union just used the excuse that the orbital height of the navigation satellites is not high enough and they are mixed with other communication frequencies, so they put an experiment on the domestic navigation satellites.  Product hat does not recognize that the applied frequency band has been occupied.

    But the European navigation satellites clearly read "Galileo-1 Experimental Satellite". The Bureau of the International Telecommunications Union is like a blind man. It not only praises Europe's contribution to the world's aerospace, but also clearly admits that the navigation frequency band applied by Europe has officially become a  part of Europe.

    If this matter were to be known to the melon-eating masses, it would definitely cause an uproar, but the people sitting in this multi-functional conference room were not that bored.

    There is no way, everyone here has become accustomed to similar things for so many years. Isn¡¯t it just double standards? If you want to cure it, it is very simple. Raise the standards to a place where these guys can¡¯t even reach. Then it will no longer be double standards.  , but the contrast is cute.

    What¡¯s more, the International Telecommunications Union is just an international organization. If you like it, it looks like that, but who does it matter if you don¡¯t?

    The key now is that the Europeans have taken the lead. Can the domestic side catch up in a short time? As long as the navy can put its dumpling energy on the navigation satellite, there will be a flying monkey in a short time, thus forming a navigation satellite.  Networking, using technical means to cover the frequency band and lock it, is the key to victory!

    But everyone knows the method, but no one dares to speak easily. There is no way, the difficulty here is beyond imagination.

    But at this moment, the head of the headquarters added another sentence, which made everyone present feel calm again: "You all know that the Free and Beautiful Room used F-15 to launch anti-satellite missiles some time ago. You should not use it to do whatever they want.  Let me explain more, so if we can launch the navigation satellite before April next year, it is best to conduct an anti-satellite test before then. Just having a shield is not enough, we also have to let others know that we are also good at spears!"
