Chapter 2838

Navigation satellites are very simple to say. They launch dozens of satellites into the sky, then form a network to provide accurate clock signals to the following. Combined with the orbital position of the satellite, they can determine their own position.

However, how do satellites in the sky form networks and design orbits? The number of satellites used in different orbits is different. The cost of satellites is quite high. If they can be used less, they will naturally be less. However, if they are used less, they are not enough to provide high enough accuracy. There is a problem of trade-offs.

As a country that has completed the networking of global positioning system, China can certainly give some favorable suggestions now.

Qin Guan smiled: "I'm also a layman. In terms of our aerospace, we can communicate with each other and experts. That's the most effective way. I'll just listen to it."

Qin Guan did what he said. At this meeting, Qin Guan was just an audience, watching them communicate with each other, all kinds of professional knowledge. Qin Guan didn't understand and couldn't talk.

Of course, their communication is still very tall. Speaking of various prospects, it's called an exciting spirit. It seems that the future will be their era.

"Galileo, we will name this navigation system after Galileo." a representative spoke.

As a famous astronomer, Galileo is the pride of Europe. It is well deserved to name him after him.

Palladio has been silently watching Qin Guan and found that Qin Guan did not have any dissatisfaction. It seems that the news of the people of the chicken country did not have any impact on President Qin. The last time the people of the chicken country wanted to export, the people of the Han country called a big fight. Now, why are the people of the Han country suddenly silent? Do they know they can't stop it? In order to avoid making a fool of themselves, they simply don't express their opinions?

It is absolutely impossible for president Qin not to know. He has a wide range of sources. How can he not know?

"Well, we have made great progress in today's meeting." finally, after some discussion, Palladio summarized: "we can't start this project without president Qin's proposal. Here, we invite President Qin to give us a speech."

Now that Qin Guan has come, he has to say something. After all, this project really started under the proposal of Qin Guan. Although some countries have ideas, no one has said it. President Qin publicized it in a big way, which moved all countries and led to this meeting today.

"In fact, without me, everyone would have made this choice. I'm just an outsider. After all, we have an old saying that those who are in the game and those who are on the sidelines are clear." Qin Guan said: "here, I wish the Europeans their own satellite navigation system project to start smoothly and run smoothly in the future."

That's it?

"President Qin, please tell us more about the development of aerospace in China. Our young men are trying to learn Chinese," Palladio said.

Now that he has said so, Qin Guan will not hide it. Now, the era of his home court has finally come.

"Space is the future for mankind. One of our predecessors said that the earth is the cradle of mankind, but mankind can't stay in the cradle forever." Qin Guan said: "There are two kinds of manned space vehicles. One is the means of transport. Whether spaceships or space shuttles, they can only stay in space for a short time. Only the space station can stay for a long time. Therefore, if we want to conquer space, we must have a space station and do scientific research in space for a long time. In China, we already have the Long March 5 heavy carrier rocket, which can Launch tens of tons of modules into space at one time. The weight of each module of our space station is about 20 tons, and then build a huge space mechanism through combination. The preliminary plan is that the total weight is about 100 tons, and the ability to increase the module at any time. "

Han's recent space program is these, developing manned spaceflight, developing space stations, and finally forming a space station to live in outer space for a long time.

"Of course, what China can do, so can Europe." Qin Guan said, "Europe can also unite to develop its own space station. If you think the technology is not enough, you can pull up the big bear country. Anyway, the big bear country is also a country of Europe."

Qin Guan is fooling them again. Your European Space Station, so don't want Eagle country. If Eagle people join in, it won't be yours.

As for how they choose in the end, it is not Qin Guan's business.

The state of Han would never build it together with them, because Qin Guan knew what these guys were, and it was almost the same as holding back each other. They all had their own thoughts. It was impossible for them to cooperate honestly.

Now, Qin Guan introduced the Han country's own space plan, which made everyone present marvel. The Han country has developed too fast in recent years. Now it has manned spaceflight and has its own space station. This kind of project is really enviable.

"So, do you plan to develop the space shuttle?" someone asked.

Han's activities cannot be concealed. Many Aerospace experts have been collected from Xiong. What do they want to do?

"No, we don't intend to develop the space shuttle. Now we have a spaceship, and the goal of the next stage is the space shuttle." this is the most important purpose of Qin Guan's coming here. He told the world that the technology of Han is the most advanced. Even if we buy Dassault's fighter, it can't play any role.

"The space shuttle?" everyone was shocked. "The technology needed by the space shuttle is far more than that of the space shuttle. What method are you going to use?"

All the experts present are naturally aware that an aerospace plane needs an engine to take off and land horizontally.

"The way of carrying a plane with a hunchback." Qin Guan said: "we have started this project. First, we use a transport plane to carry a hunchback aerospace plane to a speed of about Mach 6, at an altitude of 30000 meters, and then launch the aerospace plane."

"Such a space plane can reach space in the most fuel-efficient way. Its members may not be many. Like spaceships, it is the size of three or four people, or even only one person. However, the flexibility of this way is far beyond the current space technology."

In fact, Qin Guan has put forward this view before, and many data are still problematic. For example, there are several statements about the carrier speed below, but now, everyone has heard an important data he revealed. There may be only one person in this space plane. What is it? Sky fighter!
