Take Off My Aviation Era

As soon as Zhuang Jianye said this, the scene that had a good atmosphere because of the GSN-500MAX precision-guided bomb became strange and cold like a cold wave.

Especially the head of the headquarters, his face was neither sad nor happy, but those eyes that saw through the world flashed through a period of struggle, half helplessness, and finally intertwined into indecisable hesitation, and finally returned to an indescribable silence.

Did the head of the headquarters and others know what Zhuang Jianye said?

Of course it is clear, even better than anyone in the country. You have to know that because of the GPS problem, there were two major setbacks in 1994 and 1996, which caused the country to be pinched, and there was no chance to struggle. Aggrieved, bowed his head to admit counsel.

As the saying goes, know the shame and then be brave, so the country launched its own satellite navigation system in 1994.

However, this kind of infrastructure arranged in the low-Earth orbit space is not a play house. Once the upper lip touches the lower lip, things can be done by standing up.

That is a comprehensive industry that requires scientific research, funding, and even national strength.

Not to mention other things, that is, ordinary bridges and roads are built and drawings are drawn, equipment is put in, and people are recruited before they can start work, let alone a satellite navigation system aimed at the stars and the sea.

So as soon as the project was launched, it encountered unprecedented challenges.

The first is the question of funding. According to calculations by relevant departments, if a high-level global satellite navigation system like the US GPS is to be built, it is conservatively estimated that 100 to 150 billion yuan will be needed.

This is still a direct investment. If you count the fragmentary indirect investment, the total scale may exceed 240 billion yuan.

The 240 billion in the mid-1990s, even if the time span reached 20 years, would have to invest 12 billion annually.

The problem is how much economic efficiency this long time span and such a large scale of investment can bring to the country, how much GDP it can boost, and how much industry development it can promote are all unknown.

Because the entire project takes at least ten years to see the initial results, so many decision-making and approval leaders retired, or even passed away for a long time, it may not be able to see the effect.

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 some projects that have seen results in the near future than bet on what will happen after ten or twenty years.

The second is the technical problem. The domestic satellite navigation can be said to have no experience, so there is no so-called technical reserve. Starting from scratch is naturally difficult. Regardless of the other things, just talk about the nuclear clock on the navigation satellite. , After several times in various domestic units, no one has seen what this thing looks like. Naturally, there is no manufacturing, let alone accuracy.

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 for setting up satellite timing ground stations in the world.

Not to mention domestic, that is, Russia and Europe do not have it. The only thing that can deploy ground stations around the world without any scruples is the only superpower in the world today, the United States.

This is why the American GPS can achieve precise timing and positioning is the key, because in the global satellite navigation system, if the satellites in space are the eyes, then the supporting ground station is the ear.

The absence of either 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 ground station of the United States in Tokyo, Japan failed, which caused the GPS signal covering East Asia to be delayed and the accuracy was reduced.

This shows the importance of the ground station to the entire global positioning system.

If this example is not a big deal, then look at the Russian GLONASS satellite navigation system. From the satellite technology to the entire network layout, to the frequency and model used, the Russian GLONASS is from all aspects Generally speaking, it is no worse than GPS.

But when it comes to navigation, GLONASS’ signal and accuracy are not as good as GPS.

What is the reason?

Quite simply, the coverage of the Russian ground timing stations is not as large and dense as the United States.

In the Soviet era, relying on the strong political influence of the Soviet Union, the so-called global deployment can be achieved. Therefore, there is nothing wrong with adopting the same global satellite navigation system as the United States. Who makes people a superpower?

But with the disintegration of the Soviet Union, Russia's influence has shrunk extremely, let alone global deployment, that is, the republics of the former Soviet Union sometimes ignore Russia, and each deduces the CIS as a reality.

As a result, the ground station cannot be deployed globally, and it is naturally impossible to achieve full coverage of positioning, which directly causes the Russian GLONASS system to be horrible.

There is really nothing to say about one-acre three-quarters of land in Russia, but it is not flattering except for Russia. Thanks to the fact that China and Russia are neighboring countries, the ground timing station in Vladivostok can provide for East Asia The timing is fairly accurate, which can support the GSN-500MAX precision guided bomb of Ascendas Group.

But even so, the scope of application of the GSN-500MAX precision-guided bomb is limited to the area north of Fujian Province, and the accuracy of the further south is not accurate.

Because in the vital Southeast Asian region, Russia’s ground station in Cam Ranh Bay, Vietnam, was cancelled when the Soviet Union disintegrated. This resulted in a vacuum in Southeast Asia’s timing, and naturally there was no precision.

Even Russia, which inherited the Soviet Union, suffered from such embarrassment. The satellite navigation system that had been spent heavily on the construction of the satellite navigation system was only a small part of it.

The political influence is not as good as that in Russia today. How can the world be admired and donated money and land for you to build a ground station?

Is it as safe as Russia?

No problem at home, what should I do if I leave the country?

You know that the small incident in 1994 occurred in the Arabian Sea, thousands of kilometers away from the country, and the satellite navigation system that was built with a huge amount of money must be switched to GPS after leaving the border? Then build a woolen yarn!

It is precisely because of this key reason that can not be avoided, let alone foreigners, that is, the domestic people are not optimistic about this project, and this is the root cause of the obscure attitude of various leaders.

Can't you see hope at all, do you have a hammer?

It took more than 240 billion yuan and took 20 years to get a chicken rib that can only be used within the borders. If you leave the house, no one can afford such a big responsibility. Naturally No one dared to carry it.

Even if the head of the headquarters is a very responsible leader like ~www.readwn.com~, he dare not endorse this project, so he chose to remain silent after hearing Zhuang Jianye's words.

As the most staunch supporter and promoter of the domestic global satellite navigation system, Zhuang Jianye, of course, knows the reason for the cold scene at the moment, but he did not change the subject after seeing the collective silence of the leaders as before. Quandang did not say this. , But cleared his throat and continued:

"Chief, I still insist on my opinion, even if the current difficulties are great, but as the common people say, the living cannot let the urine be suffocated. There are always more solutions than difficulties."

"Xiao Zhuang, we understand your mood to promote the global positioning system, and we also support it from the bottom of my heart." Zhuang Jianye asked helplessly as soon as he landed a senior leader of the army: "The problem is that the ground station is not difficult. 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 funding is second. The key is how to convince these countries to open up their land to us. Tell us, we should How do you move these 33 countries?"

In the face of questioning, Zhuang Jianye did not evade, and directly asked: "Why do we want their land? Does the ground station have to be on the ground to be effective? Isn't it possible to hit the sky?"
