Top Student

"Ms. Xu, this is an office specially prepared for you. All relevant materials are in the computer and on the bookshelf. You can take a look at it yourself. If you have any questions later, I will arrange other experts to work with you. Let's communicate. Wait a while for dinner, and I'll ask you to have dinner together."

"Okay, Teacher Yu, you can go to work first."

After Yu Guangsheng came out of Xu You's office, he closed the door.

Suddenly, Xu You felt a complete silence.

Xu You could guess that this was probably an office specially prepared by Wu Jing for herself.

Since Wu Jing was able to learn so much information about Xu You when he was in college.

It is also possible to know that Xu You has the habit of studying alone.

Such a quiet atmosphere is just right for Xu You to enter the state of deep learning.

Xu You roughly glanced at the books on the bookshelf.

There are about a hundred books on the entire bookshelf, many of which are related to satellites.

Xu You took out a book casually, opened the contents, and knew that it was not simple knowledge.

In addition to the books, there are also a lot of printed materials next to it, which are more internal information.

On the computer, there are hundreds of related documents.

The entire amount of knowledge is huge, and even an excellent college student of a related major may take several years to learn all of these things.

But for Xu You, the time required will be greatly reduced.

At this time, Xu You did not feel pressured by too much information, but was in a state of excitement and anticipation.

Ever since Xu You became a university teacher, he rarely had the opportunity to devote himself to his studies.

Sometimes, Xu You feels that studying is more interesting than doing scientific research.

The sense of pleasure brought by learning knowledge is not the same as the sense of accomplishment from doing scientific research and making achievements.

The pleasure brought by learning is irreplaceable by other things.

Xu You carried the stacks of books on the shelf to the desk.

Turning on the state of deep learning, Xu You began to learn and conquer knowledge.

A few days passed.

Xu You read all the documents in the room at an incredible speed.

After continuous improvement day by day, even though Xu You's learning level is still at the fourth level, his learning efficiency has been greatly improved.

Some improvements are accumulated every day, rather than obtained all at once after the learning level is improved.

Of course, after reading all these materials, Xu You still has some questions and cannot fully understand them, and needs to communicate with those experts.

Xu You found Yu Guangsheng and explained to him that he had read all the materials.

"Ms. Yu, can you call some experts for me so that I can have a face-to-face exchange with them? I have read all these materials, but there are still some points that I have doubts about."

"Mr. Xu, have you read all of them?"

Yu Guangsheng was extremely surprised by what Xu You said.

These materials are almost all the important materials of the Fifth Academy.

According to Xu You's mission, Xu You only needs to read some information about satellites.

Even if you read the information on the satellite part, it will still take a month less.

Yu Guangsheng had heard that Xu You studied very fast, but he didn't expect it to be so fast.

"Yes, I have read all of them. These materials are really precious, and I have no access to this knowledge outside."

"Of course, this is all the most internal information. Then I will call some experts over now."

After that, Yu Guangsheng called several designers and engineers from the Aerospace Academy over.

Through these few days of understanding, Xu You knew that Yu Guangsheng had a high status in the Fifth Academy, and other people generally called Yu Guangsheng President Yu.

This shows that only Xu You and Wu Jing have the privilege to call other people "teachers".

Xu You didn't know why there was such a difference.

But it seems that Wu Jing's level is much higher than Yu Guangsheng's.

Xu You felt that it was right to do what Wu Jing said.

After face-to-face communication with these experts.

Xu You finally solved the confusion in his heart one by one.

At this time, Xu You already had some basic ideas on how to improve the resolution of satellites.

"Let's calculate the resolution limit first."

Because reconnaissance satellites are all distinguished by electromagnetic waves.

Therefore, they all have a theoretical resolution limit.

Xu You drew a model diagram of the problem on the draft paper, and quickly released the relevant formula.

θmin=1/R=1.22λ/D.

That is, the limiting resolution angle is equal to 1.22 times the wavelength divided by the optical aperture.

In this case, the diameter of the required telescope can be calculated according to the satellite orbit radius, ground resolution, light wavelength, and resolution angle.

In theory, as long as the diameter of the telescope is large enough, very high ground resolution can be achieved.

For example, if you want to achieve a resolution of 1mm, it can be done theoretically.

only……

In this case, a telescope with a diameter of about 185 meters is required.

Such a terrifying telescope, according to the existing rocket carrying capacity, is definitely impossible to send into space.

Xu You appropriately changed the orbital radius and resolution requirements.

Through calculation, according to our existing rocket carrying capacity, it is theoretically possible to achieve centimeter-level resolution.

Of course, this model calculation is only a very preliminary inference.

In order to truly realize the launch of satellites, there are many, many technologies that need to be considered.

Including satellite pointing accuracy, satellite stability, multi-mirror splicing, diffractive optical film, etc.

Xu You must also consider possible problems such as narrow vision and limited ability to distinguish between true and false.

Because the whole problem was too complicated, Xu You didn't decide on a specific design plan for a while.

Before confirming the design plan, Xu You needs to sort out the various conditions and then clarify the direction of the design.

Xu You found Ren Wendou, whom he had communicated with before, and asked some in-depth questions about this satellite.

Ren Wendou is the chief designer of the satellite for this project, and Ren Wendou is the one who knows the satellite best.

"Teacher Ren, I have a few things that I want to discuss with you again."

"Teacher Xu, please tell me."

"For our satellite launch plan this time, as long as the satellite's resolution is sufficient, other issues are secondary, right?"

"It can be said. Because our batch of satellites are also high-scoring satellites. The so-called high-scoring refers to high-resolution. This is our ultimate goal."
