- As soon as Zhuang Jianye said these words, the scene, which was originally a good atmosphere due to the gsn-500max precision guided bomb, became strange and cold as if a cold wave had blown through.
Especially the head of the headquarters, his expression was neither sad nor happy, but his eyes that could see through the world flashed with a struggle, a half-point of helplessness, and finally intertwined into undecidable hesitation, and finally fell into an indescribable silence.
??Aren¡¯t the head of the headquarters and others clear about what Zhuang Jianye said?
Of course I know it, even better than anyone in the country. You must know that due to GPS problems, we encountered two major setbacks in 1994 and 1996. As a result, the country felt like someone was pinching the balls, and there was no chance to struggle. Be able to bow your head in frustration and admit defeat.
As the saying goes, knowing shame leads to courage, so China launched its own satellite navigation system in 1994.
"However, this kind of infrastructure deployed in low-Earth orbit space is not just a matter of playing tricks. Just touch your upper lip to your lower lip and set a flag to get things done.
That is a comprehensive industry that requires scientific research, funds, and even national strength to support it.
Not to mention other things, for ordinary bridge construction and road paving, you have to draw the drawings, install the equipment, move in, and hire the personnel before you can start the work, not to mention the satellite navigation system aimed at the stars and the sea.
So once the project was launched, it encountered unprecedented challenges.
The first is the issue of funding. According to calculations by relevant departments, if we want to build a high-level global satellite navigation system similar to the US GPS, it is conservatively estimated to require 100 to 150 billion yuan.
This is still direct investment. If you include bits and pieces of indirect investment, the total scale may exceed 240 billion yuan.
240 billion in the mid-1990s, even if the time span is 20 years, the annual investment will reach 12 billion.
The problem is that over such a long time span and such a large scale of investment, it is still unknown how much economic efficiency it can bring to the country, how much GDP it can stimulate, and how many industries it can promote.
Because the entire project takes at least ten years to see initial effects, many leaders who make decisions and approve the projects retire or even pass away without being able to see the effects.
If the results are good, everyone will be happy; if the results are bad, who will bear the responsibility?
The uncertainty is so great that many leaders are discouraged. They would rather approve more projects that have achieved results in the near future than gamble on what will happen in ten or twenty years.
The second is the technical issue. It can be said that China has no experience in satellite navigation, so there is no so-called technical reserve. Starting from scratch is naturally very difficult. Regardless of other issues, let¡¯s just talk about the core equipment on the navigation satellite, the atomic clock. , I visited various units in the country several times, but no one has seen what this thing looks like. Naturally, there is no manufacturing, let alone precision.
¡°The atomic clock is only a core component of the global satellite navigation system. As for the service life of satellites, the integration of internal equipment and other issues, they are all insurmountable problems for the global satellite navigation system.
The last and most important point is that China does not have the objective conditions to set up satellite timing ground stations around the world.
Not to mention domestically, even Russia and Europe do not have it. The only one who can deploy ground stations around the world without any scruples is the only superpower in the world today, the United States.
This is also the key to why American GPS can achieve precise timing and accurate positioning, because in the global satellite navigation system, if the satellites in space are the eyes, then the supporting ground stations are the ears.
The absence of either of the two will make the global satellite navigation system deaf and blind.
Take the GPS signal failure a few years ago as an example. The reason is that the U.S. ground station in Tokyo, Japan, failed, causing the GPS signal covering East Asia to be delayed and the accuracy reduced.
It can be seen the importance of ground stations to the entire global satellite positioning system.
If this example is nothing, then take a look at Russia¡¯s GLONASS satellite navigation system. From the technology of the satellite itself to the entire network layout, to the frequencies and models used, Russia¡¯s GLONASS has many aspects. It's no worse than GPS.
But when it comes to navigation, the signal and accuracy of GLONASS are not as good as GPS.
What is the reason?
It¡¯s very simple. The coverage area of ??Russia¡¯s ground timing stations is not as large and dense as that of the United States.
In the Soviet era, relying on the Soviet Union¡¯s strong political influence, it could achieve so-called global deployment. Therefore, there is nothing wrong with using the same global satellite navigation system as the United States. Who is a superpower?
But with the disintegration of the Soviet Union, Russia¡¯s influence has shrunk extremely, let aloneThe global deployment is that even the former Soviet republics sometimes ignore Russia and go their own way to interpret the CIS as a reality.
Therefore, ground stations cannot be deployed globally, and naturally cannot provide full coverage of positioning, which directly leads to the fact that Russia¡¯s GLONASS system is useless.
There is really nothing to say about the one-third-acre land in Russia, but it cannot be complimented except by Russia. Thanks to Russia being a neighboring country, the ground timing station in Vladivostok can provide services to East Asia. Relatively accurate timing can support Ascendas Group's gsn-500max precision guided bomb.
But even so, the scope of application of the gsn-500max precision guided bomb is limited to the north of Fujian Province, and the accuracy is lost further south.
Because in the crucial Southeast Asia region, the Russian ground station set up in Cam Ranh Bay, Vietnam, was canceled when the Soviet Union collapsed, resulting in a vacuum in timing in Southeast Asia, and naturally there is no accuracy.
Even Russia, which succeeded the Soviet Union, encountered such embarrassment, which resulted in the satellite navigation system that spent huge sums of money to build was only half-baked.
¡°How can a country whose political influence is not as good as that of Russia today be able to convince other countries in the world to donate money and land to build ground stations for you?
????????????Is it just like Russia?
It¡¯s no problem arriving within the country, but what should I do if I leave the country?
You must know that the small incident in 1994 happened in the Arabian Sea, thousands of kilometers away from the country. The satellite navigation system was built at a huge cost. When leaving the national border, you had to switch to GPS? Then build a yarn!
Precisely because of this unavoidable key reason, not to mention foreigners, even people within the country are not optimistic about this project, and this is the root cause of why various leaders have an unclear attitude towards this project.
There is no hope at all, why should we get a hammer?
It took more than 240 billion and 20 years to come up with a useless product that can only be used within national borders and has no use outside the house. No one can afford such a huge responsibility, so naturally No one dared to carry it.
Even the head of the headquarters, a very responsible leader, did not dare to endorse this project and simply chose to remain silent after hearing what Zhuang Jianye said.
As the staunchest supporter and promoter of the global satellite navigation system in China, Zhuang Jianye certainly knew the reason for the silence at this moment, but he did not change the topic after seeing the collective silence of the heads of state as he had done in the past, pretending that he had not said these words just now , but cleared his throat and continued:
"Chief, I still stick to my opinion. Even if the current difficulties are great, as the people say, a living person cannot be suffocated to death. There are always more solutions than difficulties."
"Xiaozhuang, we understand your mood in promoting the global satellite positioning system, and we support it from the bottom of our hearts." As soon as Zhuang Jianye finished speaking, a senior leader of the army asked helplessly: "The problem is that the ground station is not difficult, but There is no answer. You should have seen the specific details. It is necessary to set up 183 ground stations in 33 countries around the world. The next step is to get the funds. The key is how to persuade these countries to open their land to us. Tell me, what should we do? How can we convince these 33 countries?¡±
Faced with the question, Zhuang Jianye did not shy away and asked directly: "Why do we want their land? Does the ground station have to be on the ground to be effective? Can't it be shot up to the sky?"
