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

In fact, there have been several big discussions on the issue of navigation satellites in China, and even one of the big discussions was personally promoted by Zhuang Jianye. Only in this way has the two paths of international cooperation and independence been formed.

However, due to various reasons, international cooperation still prevails, and therefore more financial support is obtained. On the one hand, 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 The deepening of the euro, especially the official issuance of the euro, Europe will inevitably become the other pole against which the United States is the only superpower.

As a result, a unified market and a unified currency in Europe are bound to usher in a wave of strong development, relying on the foundation accumulated since the industrial revolution.

At this time, it is a good choice for China to catch the fast-developing ride in Europe.

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

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 a horse with a hip.

In this regard, Europe is able to ensure that the quality of the atomic clock is controlled below 20 kilograms, the power consumption is within 30 watts, and the lifespan can reach at least 5 years.

This is not too friendly for satellite platforms with limited space and limited power consumption.

And this is not the limit of the European atomic clock. The next generation cesium atomic clock being developed by the European Precision Instrument Group in Switzerland can not only control the timing accuracy to 5 parts per billion in frequency stability, and the 24-hour drift rate of less than 1 part per trillion. First, to give 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 will be the same as the GPS Ⅲ that the United States is preparing to launch. It will completely eliminate the bulky hydrogen atomic clock and use rubidium atomic clock and cesium atomic clock to back up each other. The navigation capability with the highest accuracy below one meter makes it the most advanced navigation system in the world.

Compared with the glamorous European atomic clock, the domestic thing is the difference between the grass chicken and the phoenix, the gap is not generally large.

Because of this, even if you are a staunch independent faction, you are not opposed to foreign cooperation. After all, learning foreign advanced technology is also a hidden attribute of foreign cooperation. Since the domestic is not doing well in some aspects, then you must learn with an humility. It’s up to you to get pregnant at a glance, or to get pregnant at a few glances, or to dedicate yourself directly to the motorcycle racing to get pregnant, it depends on your own abilities.

However, whether it is an international cooperation group or an independent group, the idea of ​​relying on external forces for their own development is completely disillusioned, because the head of the headquarters has made it clear that the cooperation plan with Europe is in name only.

...

"I won’t talk about the specific nonsense of international politics and geostrategy, but will emphasize three points. First, the money we invested has been lost; second, we have not learned anything; third, the International Telecommunication Union The ruling is very unfavorable to us, so I’m looking for you to come over today, just to hear you, can we rely on ourselves to send a fully mature navigation satellite to the sky before April 2007, and issue a navigation frequency approved by the International Telecommunication Union?"

The head of the headquarters was as clean and tidy as ever, but as soon as this was said, everyone present was surprised at the same time. It is now December 2006, and it is still on the 28th, rounding down is 2007.

The industry insiders in these aerospace fields still don’t know where the mature next-generation navigation satellites are present. How can it be possible to complete this task in more than three months?

Even if you step back 10,000 steps, you now have mature navigation satellites in your hand. Space launch is not a trivial matter. You need to calculate the window period, orbit, fixed angle, coordinate the measurement and control of the ground and the sea. Months can't come down at all, so more than three months is not enough.

However, if mature navigation satellites are not sent to designated orbits before April 2007, and navigation signals are transmitted in accordance with the provisions of the International Telecommunication Union, the navigation frequency bands previously applied for in China will be completely scrapped, and the Europeans will eat it. The difference between the two sides is only a few tenths of an error. A slight modification of the demodulator can completely cover the domestic frequency, and then there will be no chance for the country to want it.

Of course, some people will ask at this time, hasn't the country already launched experimental navigation satellites, why didn't it occupy its own frequency; the navigational experimental satellites launched by Europeans will do?

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

Such a combination will know it is the old double standard as long as the eyes are not blind.

This is indeed the case. The domestic navigation satellites have already been marked with 4, but the presidium of the International Telecommunications Union just grasped the navigation satellite’s orbit height is not enough, mixed with other communication frequencies, and gave the domestic navigation satellites an experiment. The product hat does not recognize that the applied frequency band has been occupied.

However, the European navigation satellite brightly wrote "Galileo-1 Experimental Star", and the Bureau of the International Telecommunication Union, just like the blind man, not only praised Europe’s contribution to the world’s aerospace, but also brightly admitted that the navigation frequency band applied by Europe has officially become Part of Europe.

If this matter is known to the people who eat melons, it is guaranteed to cause an uproar, but the people sitting in this multifunctional conference room are not so boring.

No way, all of you who have been here for so many years of similar things have been surprised~lightnovelpub.net~ Isn’t it a double standard? If you want to cure it, it’s very simple. Raise the standard to a position where this group of guys can’t reach it. At that time, it will not be a double standard, but a contrast.

What's more, the International Telecommunication Union, an international organization, looks like that if it is pleasing to the eye. How old is it if it is not pleasing to the eye?

The key now is that the Europeans have already taken the lead. Can the domestic side catch up in a short time? As long as the navy’s energy of dumping dumplings can be placed on the navigation satellites, a short-term sky monkey will be formed to form a navigation satellite. Networking, using technical means to cover the frequency band and lock up, this is the key to victory!

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

But at this moment, the head of the headquarters added another sentence, which made the already calm hearts of everyone present once again chilled: "You all know how to launch anti-satellite missiles with F-15 some time ago in Liberty Beauty Room. You shouldn't use them for what they want to do. Let me explain more, so if we can launch a navigation satellite before April next year, we'd better do an anti-satellite test before then. A shield alone is not enough, and we have to let others know that our spears are not bad!"
