"What about the money?"

"How much do you want?"

"How much can you give?"

"It depends on what kind of precision you can come up with. ”

"You say. ”

"One centimeter, one hundred million. One millimeter, a billion. 100 microns, you offer ......"

"Good. ”

Wang Buan nodded with satisfaction.

Good price.

Everyone was happy.

A win-win situation for both parties.

Strictly speaking, Beidou satellites are not reconnaissance satellites.

Its main role is to implement precise positioning and is a navigation satellite. Taking pictures is only part-time. There are some secrets that cannot be made public.

In short, we say to the outside world, after buying the parts back, they are all supporting Beidou satellites.

Beidou satellites are not for military use. Rest assured.

Of course, after buying it back, it will be ......

However, others are not fools either.

Some key parts are not sold.

It's not just that you don't sell it. It is also forbidden for others to sell. If anyone sells it quietly, Uncle Sam will spank him.

Although Hans and Uncle Sam are not very on the right path. There have also been two bloody battles in history. But on this issue, I don't dare to mess around. After all, Uncle Sam is now the strongest in the world, and if he says that he can play the board, he will really play the board. You must know that this kind of high-precision parts seriously threatens Uncle Sam's own safety, so how can you ignore it?

In outer space, Uncle Sam also has an absolute hegemony. Of course, I don't want to be threatened.

The flight altitude of a fighter is generally about 20 km.

Only a very small number of fighters can exceed 30 kilometers (30,000 meters) in ceiling.

However, the minimum satellite is more than 200 kilometers.

The general orbital altitude of satellites is 30,000 or 40,000 kilometers.

In other words, if you want to take pictures, the minimum altitude is 200 kilometers or more. Normally, it is 30,000 kilometers, or even 40,000 kilometers at an altitude.

In the beginning, the accuracy of satellite observations ranged from 10 meters to 5 meters, 3 meters, 1 meter, and 0.5 meters.

Now it's accurate to 0.1 meters.

What exactly is the concept of 0.1 meter class here?

Earth observation with an accuracy of 0.1 meters allows us to see everyone present, men, women and children, and even your license plate number.

At present, the highest resolution of the world's most advanced civil commercial satellite, orldVie-3 of a certain country, is 0.31 meters, the highest resolution of China's "Gaojing" series of commercial remote sensing satellites is 0.5 meters, and the resolution of another commercial remote sensing satellite in China "Jilin No. 1" (Changguang No. 1) is also 0.5 meters. On the whole, China's commercial remote sensing satellites have basically caught up with the world's advanced level, and the next step will be to launch 0.3-meter commercial satellites to catch up with the world's first-class level.

The accuracy of commercial satellites is not the scope of Wang Buan's research.

His field of study is very specialized.

Military reconnaissance satellites.

In recent years, a certain superpower has attached great importance to the tactical application capability of the reconnaissance and surveillance satellite system from the perspective of combat missions and the capabilities it requires, and the reconnaissance and surveillance satellite systems in service mainly include the "keyhole" series of optical reconnaissance satellites, the "lacrosse" radar imaging satellites, and the ORS series of satellites. Optical imaging reconnaissance equipment such as multispectral and hyperspectral sensors have a maximum resolution of 0.1 meters (0.05 meters).

After the abolition of the "Future Imaging System" optical satellites, the "Keyhole" series of optical reconnaissance satellites represents the highest level of optical reconnaissance satellites of the lighthouse country. In 2011 and 2013, the Lighthouse Nation successfully launched the NROL-49 satellite and the NROL-65 satellite. Among them, the NROL-65 launched in 2013 is the latest deployed "Keyhole"-12 satellite. The highest accuracy is 0.1 meters.

Due to the very high resolution of keyhole satellites, countries around the world are very afraid of it.

A certain country also took the opportunity to boast that the accuracy of the keyhole reached the level of 0.05 meters. That's 5 centimeters. Even the headlines of the newspapers can be read clearly.

Facts have proved that there is an element of exaggeration in a certain country. Reading clearly in newspaper headlines is a complete gimmick.

This so-called 0.05-meter accuracy is detected in the harshest environments. It is required that there are no obstacles. There can be no dust.

If it's our haze weather, don't say it's 5 cm accuracy. 5 km can't do it.

Smog anti-satellite, not a joke. It's tangible.

It's a little bit difficult for us to catch up with this accuracy.

The biggest reason is the lack of sufficiently precise optical lenses. That's someone else's housekeeping skill, and it won't be sold easily.

If you do your own research, you need a lot of prerequisites. One's eyes are bigger than one's stomach..

It's not a question of funding. It's a matter of technology accumulation.

Layer by layer, it takes a long time.

What to do?

If you have difficulties, look for Wang Buan.

Now, Wang Buan's task is to increase this resolution to 0.1 meters.

If it can be lifted to 0.01 meters, so much the better.

This involves very specialized optical technology.

Optical technology is one of the most cutting-edge technologies.

Among them, special glass is another branch.

Don't think that special glass is bulletproof glass. In fact, it has quite many branches. Optical glass is one of them.

There are also people who extract optical glass separately to form a closed research system.

Carl Zeiss and Schneider are among the best.

Lycra is also slightly inferior in terms of professional field.

Of course, compared to other optical research, the degree of expertise of Lycra is also very high. It's also great to be LYCRA certified.

"How's it going, do you have confidence?" said Pang Xihua.

"Yes. Wang Buan is not polite.

"Good. I wait for your good news. ”

"Good. ”

What does Wang Bu'an rely on?

Of course, it's 100 levels of scientific and technological knowledge. There is also the always special interstellar technology.

It's that (-2 level) interstellar radar lock.

This skill, upgraded from -2 to -1, requires 100 million faith points.

Without thinking, Wang Buan immediately upgraded.

Sure enough, he immediately had a lot of professional skills in his mind.

Radar locking, and satellite reconnaissance, have a lot in common. Interstellar radar, capable of locking on to the Milky Way. What is locked on Earth?

The range of interstellar radar is calculated in light years. What is 30,000 or 40,000 kilometers?

Of course, that's what is said in theory. The practical application still needs to be pondered.

Arrange a few robot elves to conduct research first.

The first step is to study the corresponding glass material.

Optical lenses require special glass and need to be subdivided.

Transformers give robot elves special abilities. To a certain extent, the raw materials can be improved.

In the industrial park, there is a raw material called optical glass.

However, there are many types of optical glass. Colored, colorless. High refractive index. Low refractive index.

In addition to glass, there is a very special raw material. That's the coating material.

Different lenses require different coating materials.

Coating materials, on the other hand, belong to the category of chemical processes.

In other words, you still have to think about the chemical process. For example, polyetheretherketone or something.

There is also a special material called optical fiber. It was originally intended for fiber optic communications. However, it is occasionally used to make lens materials.

How to add and how much to add needs to be calculated repeatedly. Trial-and-error.

Why are DSLR lenses so expensive?

There is indeed a monopoly reason for this. However, it is also true that the cost is high.

Any camera lens is produced separately. The yield rate has not been high. Of the ten lens glasses, there may be less than five that can be used. The price is naturally expensive.

"There is another news......" Pang Xihua stopped talking.

"Say it. Wang Buyan disagreed.

"You and Dou Jingluo, aren't you a little unhappy?"

"Dou Jingluo?"

"It's Yucheng's Dou Jingluo. ”

"Nope. ”

Wang Buan shook his head.

He and Dou Jingluo definitely didn't have a holiday.

He and Dou Jingluo hadn't even met. At the last auction of the Legend Shipyard of the Four Seas, Dou Jingluo did not appear.

In fact, even if he appeared, Wang Buan had already left.

The only contradiction is definitely Roselle.

It's that strange, bewitching woman. Women dressed as men, weird.

Wang Buyan doesn't like transvestism.

The man pretends to be a woman and looks disgusting.

The woman pretending to be a man also looks disgusting.

You are a man and you are a man, and if you are a woman, you are a woman. Why play someone else?

It is said that Roselle is still a man's own palace, which is even more disgusting.

I don't know where this rumor came from. Seems to be a problem?

"Dou Jingluo said something unfavorable to you. ”

"What did you say?"

"Not a good word anyway. ”

"Huh. ”

"There is also Duan Fenghua, who has been with Dou Jingluo recently. ”

"Really?"

Wang Buan smiled faintly.

Duan Fenghua.

Dou meridian omitted.

What do you want to do?

I don't seem to have touched your cheese, did I?

Thinking about Lao Tzu all day long, are you annoyed?

"The domestic situation is more complicated, and it is difficult for Cheng Kailong to deal with it. ”

"It's fine. I can handle it myself. ”

"Don't mess around. ”

"No, it won't. ”

Wang Buan said affirmatively.

How could I mess around?

I'm pretty well-behaved, right? I've never broken the law......

"If someone slaps me, I will take the initiative to send the other side of the face up and let him slap him again. When he gets tired of beating his hands, he naturally won't fight anymore. Wang Bu'an said lightly, "I endure humiliation, compromise and seek perfection, spit on myself, retreat, accept it, and ......swallow my anger."

"You ......" Pang Xihua shook his head helplessly.

"If someone gives me a crotch insult, I have to force a smile and thank you. ”

"I'm leaving. ”

Pang Xihua shook his head and left.

Idiots can hear what Wang Buan means. This little guy has never been a good guy.

It's okay that he didn't take the initiative to bully others, and he still endures the humiliation?

I hope that Dou Jingluo and Duan Fenghua will not crash into the muzzle.

It's true, what are they competing with Wang Bu'an for?
