Rebirth 2008: I Can Make Money Reading

Mu Yang is looking forward to his star network very much. He dug a hole for Musk and Chou Guo, which can make the other party speechless.

Of course, in the face of strong strength, conspiracy and tricks are of little use.

At that time, maybe seeing Xinghai Group's star network will be very helpless and dare not touch other people's satellites.

Xingkong-1 low-earth orbit LEO has a launch capacity of 200 tons. If the space is not considered and only the weight is counted, hundreds of nearly a thousand Xingdou-1 satellites can be carried in one launch.

Coupled with the powerful rocket recovery technology, the launch cost of each satellite is negligible compared to the manufacturing cost.

Therefore, Ugly Country wants to exchange wounds for wounds, touching one by one, it's not worth it!

Even if the missiles are used to blow up the Xinghai Group's satellites, the missiles that can find the satellites are more expensive than the satellites, so it's not worth it!

So, helpless!

Unless it is said that the rocket launch base of Xinghai Group was blown up.

At this level of evil, it is actually no different from starting a war. What Mu Yang has to do must be to get rid of the enemy's satellites first.

Modern warfare, without the assistance of satellites, is like a blind man.

Can't fight anymore!

With the gap in technology, the Xinghai Group can beat the opponent, just like that.

on the other hand,

The rules of international space competition are overbearing, and whoever occupies the orbit first will own it. In fact, each country builds on its own advanced space technology.

Like those countries with little aerospace technology, they have no choice but to disagree with this international rule, and they can't beat it again and again.

But when this rule does not apply to itself, that is, when the Xinghai Group uses this rule to quickly occupy space resources, these Western countries must want to re-write the rules.

Now, Mu Yang is the one who breaks the rules and becomes the one who can make the rules.

The strong make the rules, and the weak prey on the strong, just like the rules of the forest.

The Xingdou-1 satellite technology that Mu Yang just bought with achievement points is indeed very powerful.

Comparing the top satellite data of various countries, it is even more obvious.

For example, in August 2014, DG announced the successful launch of a new generation of ultra-high resolution satellite - orldVie3 satellite.

The resolution of the orldVie3 satellite has even reached a resolution of 0.3 meters, making it the highest resolution optical remote sensing satellite in the world.

Now Muyang has raised the resolution of the satellite to 0.05 meters!

It seems that the difference is only 0.25 meters. In fact, the technical level is very different. This is the same as the chip manufacturing process.

At present, the satellites launched by many countries or companies have not been able to break through to the sub-meter (less than 1 meter) resolution level.

A few years later, my country's Nandou 3 will be openly serviced with a positioning accuracy of 10 meters and a speed measurement accuracy of 0.2 m/s. The announced resolution is not greater than 1 meter. Maybe it will be lower if you use it.

Xingdou-1 can quickly collect high-definition planar satellite images and high-precision terrain data around the world with a resolution of 0.05 meters and no revisit cycle. After fusion and correction, it can generate DOM orthophoto maps or DEM, Digital products with geographic elevation such as DSM.

Note that the distance between the satellites of Starlink is very short, which means that it can monitor the ground around the clock, that is, there is no revisit cycle.

If it is only a low-earth orbit satellite, it needs to orbit the earth, and it can normally orbit several times a day.

However, if 20,000 satellites are deployed in low-Earth orbit, the entire Earth can be fully covered.

At the same time, since Xingdou-1 is also equipped with a synthetic aperture radar, which has the ability to penetrate thick clouds, no matter whether it is night or day, and regardless of whether there are dense clouds or fog, any ground target will appear in front of the Xingdou-1 satellite. .

The camera technology of Xingdou-1 is of course different from ordinary cameras.

It is optical + radar!

Of course it is not synthetic, but optical and radar (with a pot lid image) instruments are installed at the same time.

Optical satellites are certainly not the same as radar satellites!

Radar satellites are satellites equipped with radar microwave sensors. The sensors continuously emit microwaves to the ground. After these microwaves reach the ground, many of them are reflected back to the satellite for recording and imaging.

Optical satellite images are like people looking at the earth with their eyes. What they see can be in color, just like a photo. It can take visible light images, multi-spectral images, and infrared images, but it cannot see through thick clouds, and rainy days are also affected.

Radar satellite images are like people touching the earth with their hands. It reflects a "tactile sense" and can form 3D images around the clock, but they are not as beautiful as optical satellites.

The combination of the two, complementing each other's strengths, is very powerful.

Of course, if two different structures are combined into one satellite, the total weight will increase, the structure will be more complicated, and the cost will be higher.

In general, Xingdou not only has the function of taking pictures, but also has the functions of communication, remote sensing and detection.

It is a comprehensive satellite!

If you compare the Big Brother in the 1990s to a communication satellite.

Well, today's smartphones have added camera functions, GPS functions, and maybe many unimaginable functions will be added in the future.

Therefore, Xingdou No. 1 is a multifunctional mobile phone in the future! It's just that some functions are weaker than professional satellites, such as reconnaissance methods, which are not as good as professional reconnaissance satellites.

Due to the advanced technology of the system, each Xingdou-1 satellite weighs only two to three hundred kilograms.

Otherwise, the function of optical satellites alone, with the urine performance of the system, for small satellites, tens of kilograms would be enough.

If you don't understand the function of Xingdou-1, you will feel that it is nothing special.

But Mu Yang will be shocked if he knows the satellite technology level of each country and compares it.

It's a beef fork!

Perhaps, when the Xinghai Group launches this kind of integrated satellite, people who don't know it will laugh at the Xinghai Group for building a nondescript satellite.

It's like a professional photographer with a DSLR laughing at a young man with a mobile phone.

Not professional enough!

However, my mobile phone can beautify the face, but your SLR can?

Ten times the focus?

It is also no problem.

As long as the performance of the mobile phone is strong enough, the SLR that was more than ten years ago can still be eliminated.

This is just a metaphor, not to say that SLR photography is not good.

a few days later,

Mu Yang finished exporting the data of Xingdou-1 and uploaded it to the company's technical system.

Judging from the current situation of Xinghai Group, there are many parts purchased from suppliers that cannot meet the requirements, and require independent research and development, and the research and development cycle will be longer.

October 25,

nine in the morning,

Mu Yang held a meeting of the satellite project team on the 98th floor.

The space exploration technology project team is divided into three departments, the rocket engine project team, the satellite project team and the rocket project team. At present, it has grown to about 1,300 scientific researchers, including 200 scientific researchers in the satellite project team.

The people who participated in the meeting were mainly more than 20 core members of the project team. They were a little curious about the content of the meeting, but it was not convenient for them to ask colleagues, so they had to sit quietly in the meeting room, silently waiting for the chairman to arrive.

Anyway, the fact that the chairman can hold a meeting in person shows that the matter is very important. In the past year, they made preparations according to the requirements of the chairman when he established the project team. The team worked together, and the company already has the ability to develop satellites.

After everyone waited for a while, the chairman walked into the meeting room with a teacup.

A few employees were a little curious as to whether wolfberry was soaked in the chairman's cup, and their eyes seemed to be elongated, staring at the chairman's cup, but they couldn't see what was in the cup.

After scanning the crowd, Mu Yang sat down, put the cup lightly on the table, and said with a smile on his face:

"I want to tell everyone that our rocket engine prototype has been developed and is ready for ignition test.

as for this

Whether the news is good news or bad news depends on the results of the ignition.

But no matter what, it is a success to be able to complete the prototype trial production as expected. "

He also got the news yesterday that the engine will be pulled to the rocket test site for a vertical ignition test, and it is estimated that it will be installed tomorrow.

The rocket engine ignition test is very dangerous, and the reaction between liquid hydrogen and liquid oxygen may also explode. This cannot be carried out at the Xinghai Group headquarters base, and Shi ZF will not agree.

At the same time, a large amount of white smoke will be produced. If there is satellite monitoring in the sky, this test cannot be hidden at all. I must know that Xinghai Group is conducting rocket tests.

Of course, I just know that I am doing a rocket test, and it is a bit difficult to know more.

Everyone has been staring at the chairman, looking at the smile on his face, and hearing that the prototype of the engine has been made, which is indeed good news.

Mu Yang went on to say: "The prototype of the main body of the rocket is also being developed intensively, and in the end the only thing missing is the satellite."

"The theme of this meeting is to prepare for the development of Xingdou-1 satellite.

I have already entered the data into the company's technical system, and everyone is familiar with the data as soon as possible according to their own authority, familiar with their tasks, and started to develop prototypes.

The project manager then refines and arranges the time nodes according to the requirements of the general plan issued by me. After the plan is completed, I will review it. "

Next, Mu Yang asked the staff to turn on the projector in the meeting room, then he turned on the computer, logged in his account in the company's technology system, opened an encrypted file, and displayed the 3D map of Xingdou No. 1 on the projection cloth.

"This satellite, which I named 'Xingdou No. 1', has a design mass of 278 kilograms and has... I divide it into structural systems, power systems, thermal control systems, attitude control and orbit control systems, and radio Measurement and control system, etc...

Mu Yang said slowly, he had to explain the design points of Xingdou-1 to these people first, so that they could grasp the key points quickly and accurately, and at the same time distribute the tasks to the team leaders according to each system.

These scientific researchers are not useless. If they can understand and develop Xingdou-1, it will be quite difficult.

In the past year, they have done a lot of basic work. If they only develop ordinary satellites, their capabilities are sufficient.

But if you want to develop the world's top satellites, there is still a big gap.

It is impossible for Mu Yang to design it himself.

But as long as they thoroughly understand the technology of Xingdou No. 1, their personal abilities will be greatly improved.

Xinghai Group does not rely solely on Mu Yang for research and development. Last year, the company applied for more than 5,000 PTC international patents, while Mu Yang himself only had 20 or 30 patents.

If Mu Yang was alone, it would be impossible to complete so many big projects at the same time.

Half an hour later, after Mu Yang finished his explanation, the participants could ask him questions, and they had to figure out the content of the research and development project, otherwise the research and development direction would be wrong.

A team leader asked respectfully: "Chairman, let me ask you, are professional satellites better than integrated satellites? Such satellites will be lighter in weight?"

Mu Yang replied: "Well, the question you raised mainly considers the load of the rocket.

The rocket project team has not disclosed the technical parameters of Xingkong-1 to you for the time being, and now is the time.

The load of LEO can reach 200 tons, and we may not be able to make up the load for one launch.

So, don't worry about load issues.

We want to break the conventional design. Why don't they design it this way? The main reason is that it is not easy to do a good job in comprehensive satellites, and secondly, it is affected by the rocket's load capacity.

Our company is at the forefront of the world, no one will explore the way for us, we can only figure out the way by ourselves. "

Everyone nodded and was shocked at the same time.

The load of LEO has reached 200 tons, what is that concept? ! It's too exaggerated!

Although they all belong to the scientific research personnel of the space exploration technology project team, the scientific research results of each branch project team cannot be freely distributed to others.

It is made public by the project team, unless it is necessary to know, so they don't know the situation of Xing Kong No. 1 for the time being.

When Xingkong-1 is successfully developed, some technical parameters will of course be disclosed to some members of the general project team.

"Chairman, is it 200 tons or 20 tons? Such an exaggeration!"

Everyone still didn't believe it, and another team leader thought he had heard it wrong.

"It's 200 tons. If it's only 20 tons of payload, then you really have to consider the weight of the satellite. Lightweight design also means using expensive lightweight materials. Our launch cost is very low, probably less than 100,000 yuan per ton of payload, so , Some parts and materials of Xingdou-1, if not necessary, can be replaced with cheaper materials, so that the manufacturing cost of the satellite will be reduced a lot.” Mu Yang said, the original plan of 278 kg, the materials of some parts Replacements will be made, and eventually Xingdou-1 may weigh more than 300 kilograms.

"Chairman, if the load capacity of LEO reaches 200 tons, it will be great, and there will be fewer worries."

With the chairman's confirmation, everyone felt that Xinghai Group would bring another shock to the world.

Next, UU Reading www.uukanshu.com After Mu Yang explained the design idea of ​​Xingdou-1, he and his subordinates sorted out what parts of Xingdou-1 needed to be purchased and independently developed, and he was busy until he got off work at noon.

In the afternoon, Mu Yang and the staff of the satellite project team continued to sort out their work ideas, and the meeting was not considered complete until the team leaders had no doubts.

Before the meeting ended, Mu Yang reminded everyone:

"At the beginning of the year, I reminded everyone that the U.S. company SpeX Space Exploration Company is a strong competitor.

Even if we are at the forefront of the world, never underestimate our competitors. "

Mu Yang also thought about letting domestic electric vehicles enter the ugly country, but think about it, it is too difficult, and the ugly country will also try to limit the development of domestic electric vehicles in the ugly country, and will still strongly support the development of Tesla.

In fact, it was only after the factory was built in Shencheng that Tesla was able to develop. The production cost dropped sharply, and the production capacity of MODEL3 was also increased. It just coincided with Huaguo's new energy policy and the green license policy of various cities, so it could be sold well.

It’s just that, with Mu Yang as a spoiler in this life, Tesla’s history has changed.

The Shencheng Tesla factory has not yet been built, and Tesla's development is slow.

Two days later, Mu Yang will go to the rocket launch base in Ningcheng to inspect the ignition test of the Xinghuo-1 rocket engine.

He didn't expect the experiment to be successful once, but he still hoped it wouldn't explode.
