"What about the funding?"
"How much do you want?"
"How much can you give?"
"It depends on what kind of precision you can produce."
"You said."
"One centimeter, one hundred million. One millimeter, one billion. 100 microns, you make a price..."
"it is good."
Wang Bu'an nodded in satisfaction.
The price is good.
Everyone is happy.
A win-win situation for both parties.
Strictly speaking, the Beidou satellite is not a reconnaissance satellite.
Its main function is to implement precise positioning and is a navigation satellite. Taking pictures is only part-time. There are some secrets here that cannot be disclosed.
In short, we said to the outside world that after buying back the parts, they are all supporting the Beidou satellite.
The Beidou satellite is not for military use. Friends can rest assured.
Of course, after buying it back, then...
However, others are not fools.
Some key parts are not sold.
Not only do not sell. Other people are also prohibited from selling. If anyone sells it quietly, Uncle Sam will spank.
Although Hans and Uncle Sam are not quite right. Two battles broke out in history. But on this issue, I dare not mess around. After all, Uncle Sam is now the strongest in the world, and he really knows how to play the board if he says he plays the board. You have to know that such sophisticated parts and components seriously threaten Uncle Sam's own safety. How can you take it lightly?
In outer space, Uncle Sam also has an absolute dominance. Of course I don't want to be threatened.
The flying height of a fighter jet is generally about 20 kilometers.
There are only a handful of fighters whose ceiling can exceed 30 kilometers (30,000 meters).
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. Normally, the height is 30,000 kilometers or even 40,000 kilometers.
At the beginning, the satellite's observation accuracy was from 10 meters to 5 meters, 3 meters, 1 meter, and 0.5 meters.
It is now accurate to 0.1 meters.
What is the concept of 0.1 meter level here?
The ground observation with an accuracy of 0.1 meters allows us to see all the people present, all men, women, children, and children can see clearly, even the license plate numbers of everyone.
At present, the world's most advanced commercial satellite for civilian use-the highest resolution of a country’s WorldView-3 is 0.31 meters, the highest resolution of my country’s "Gaojing" series of commercial remote sensing satellites is 0.5 meters, and another commercial remote sensing satellite of our country" The resolution of Jilin No. 1 (Changguang No. 1) is also 0.5 meters. On the whole, my country'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-class commercial satellites to catch up with the world's top level.
The accuracy of commercial satellites is not the scope of Wang Bu'an's research.
His research field is very professional.
Military reconnaissance satellite.
In recent years, a certain superpower has attached great importance to the tactical application capabilities of reconnaissance and surveillance satellite systems based on combat missions and required capabilities. The active reconnaissance and surveillance satellite systems mainly include the "keyhole" series of optical reconnaissance satellites and the "lacrosse" radar. Imaging satellites, ORS series satellites, etc. Among them, the "keyhole" series imaging reconnaissance satellites are the most advanced optical imaging reconnaissance satellites in the world today. 12 models have been developed, equipped with optical, infrared, multispectral and hyperspectral sensors. The imaging reconnaissance equipment has a maximum resolution of 0.1 meters (in one word, 0.05 meters).
After the cancellation of the "Future Imaging System" optical satellites, the "Keyhole" series of optical reconnaissance satellites represent the highest level of optical reconnaissance satellites in the lighthouse. The Lighthouse Country successfully launched NROL-49 and NROL-65 satellites in 2011 and 2013. Among them, NROL-65, launched in 2013, is the newly deployed "Keyhole"-12 satellite. The highest accuracy is 0.1 meters.
Because of the very high resolution of keyhole satellites, countries around the world are very afraid.
A certain country also took the opportunity to boast that the accuracy of the keyhole reached the 0.05 meter level. That is 5 cm. Even the headline of the newspaper can be read clearly.
Facts have proved that a certain country is exaggerated. Reading the newspaper headline clearly is a gimmick.
This so-called 0.05 meter accuracy is detected in the harshest environment. No obstacles are required. There must be no dust.
If it is our haze weather, let alone 5cm accuracy. Can't do it for 5 kilometers.
Anti-satellite smog is no joke. It is real.
We want to catch up with this accuracy, there is still a little difficulty.
The biggest reason is the lack of sufficiently precise optical lenses. That is the housekeeping skills of others and will not be easily sold.
If you do your own research, you need a lot of preconditions. There is more than enough energy but insufficient energy.
It is not a question of funding. It is a matter of technology accumulation.
It takes a long time to study layer by layer.
How to do?
If you have difficulties, find Wang Bu'an.
Now, Wang Bu'an's task is to increase this resolution to 0.1 meters.
If it can be raised to 0.01 meters, so much the better.
This involves very professional optical technology.
Optical technology is one of the most cutting-edge technologies.
Among them, special glass is one of the branches.
Don't think that special glass is bulletproof glass. In fact, it has many branches. Optical glass is one of them.
Some people extract the 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 level.
Of course, compared to other optical research, Lycra's professionalism is also very high. Being able to get the Lycra certification is also very remarkable.
"How? Are you confident?" Pang Xihua said.
"Yes." Wang Bu'an was not polite.
"Good. I'm waiting for your good news."
"it is good."
What is Wang Buyan's support?
Of course it is level 100 technological knowledge. There is always special interstellar technology.
It is the (-2 level) interstellar radar locked.
This technology, to upgrade from -2 to -1, requires 100 million belief points.
Without thinking, Wang Buyan immediately upgraded.
Sure enough, there was a lot of professional skills in his mind.
Radar lock and satellite reconnaissance have many similarities. Interstellar radar can lock the Milky Way. What is locking the earth?
The range of the interstellar radar is calculated in light years. What is thirty or forty thousand kilometers?
Of course, it is said in theory. The actual application has to be pondered.
First arrange a few robot elves to conduct research.
The first is to study the corresponding glass material.
The optical lens needs special glass and needs to be subdivided.
Transformers endow the robot elves with special abilities. The raw materials can be improved to a certain extent.
In the industrial park, there is a raw material called optical glass.
However, there are many types under the optical glass. Colored, colorless. High refractive index. Low refractive index.
In addition to glass, there is a very special raw material. That is the coating material.
Different lenses require different coating materials.
The coating materials belong to the category of chemical processes.
In other words, you have to ponder the chemical process. For example, polyether ether ketone or something.
There is also a special material called optical fiber. It was originally used for optical fiber communication. However, it is occasionally used to make lens materials.
How to add and how much to add requires repeated calculations. Trial and error.
Why are SLR cameras so expensive?
There is indeed a monopoly reason. However, the high cost is also real.
Any camera lens is produced separately. The yield rate has never been high. Among ten pieces of lens glass, there may be less than five that can be used. The price is naturally expensive.
"There is another news..." Pang Xihua hesitated to speak.
"Let's talk about it." Wang Bu'an disapproved.
"Are you and Dou Jinglue a little unhappy?"
"Dou Jinglue?"
"It is Yucheng's Dou Jinglue."
"No."
Wang Bu'an shook his head.
He and Dou Jinglue must have had no holidays.
He and Dou Jinglue never even met. Dou Jinglue did not appear at the last auction of the legendary shipyard of the four seas.
In fact, even if he appeared, Wang Bu'an had already left.
The only contradiction must be Luoshen.
It was the strange and coquettish woman. The woman pretends to be a man, which is weird.
Wang Buan doesn't like transvestite.
The man pretends to be a woman and looks sick.
The woman pretends to be a man, looking disgusting as well.
You are a man or a man, a woman is a woman. Why play someone else?
It is said that Luoshen is still a man from the palace~EbookFREE.me~ that is even more disgusting.
I don't know how this rumor came about. It seems true?
"Dou Jinglue said something unfavorable to you."
"What did you say?"
"It's not a good thing anyway."
"Ha ha."
"And Duan Fenghua, he was with Dou Jinglue recently."
"is it?"
Wang Bu'an smiled faintly.
Duan Fenghua.
Dou Jinglue.
What do you want to do?
I don’t seem to touch your cheese, am I? It's you guys who come to trouble me.
Worrying about Lao Tzu all day?
"The domestic situation is more complicated, and it is not easy for Cheng Kailong to deal with it."
"It's okay. I can handle it myself."
"Don't mess around."
"will not."
Wang Buyan said affirmatively.
How could I mess around?
I am very abiding now, okay? Never break the law...
"If someone slaps me, I will take the other side of the face and ask him to slap again. When he gets tired, he won't slap me again." Wang Bu'an said lightly, "I bear the insult. , Making mistakes and seeking completeness, stubbornly stubbornly, retreats, bears, and swallows..."
"You..." Pang Xihua shook his head helplessly.
"If someone gives me a humiliation under the crotch, I have to smile and express my gratitude."
"I am leaving."
Pang Xihua shook his head and left.
Idiots can hear what Wang Buyan means. This little guy has never been a good kind.
It's fine if he didn't take the initiative to bully others, and he still endured the humiliation?
I hope that Dou Jinglue and Duan Fenghua will not hit their guns.
Really, what do they compete with Wang Bu'an for?
