Super Weapon Swap System

Beidou navigation satellite!

In the past, Qin Guan only exchanged an abandoned GPS satellite in the satellite cemetery, which was definitely an extremely open behavior. After the exchange, Qin Guan did not interfere with the follow-up work, but completely handed it over to the experts studying satellites.

It still needs a lot of efforts to get this kind of satellite out. There are too many technologies to overcome, such as what algorithm to use for navigation, how to transmit signals, and how to do the most precise atomic clock on the satellite.

Back then, it was precisely because the navigation satellite was too difficult that the Han country wanted to contact Europe and hoped to join their Galileo satellite navigation plan.

But what happened?

Galileo satellite is from Europe. Those guys are high above. If China wants to come in, you can provide how much money, but you can't get any technology!

After years of wrangling, Han finally found that advanced technology could not rely on others and had to work hard. Therefore, Han learned from the pain and embarked on the road of independent research and development.

Because it is too difficult, Han first engaged in double star positioning. This method requires a ground-based solution station and users to send information to space, which is easy to be exposed.

Although it has various defects, it was developed by itself after all, and finally gave a bad breath. At this time, Europe is still wrangling with each other, and their Galileo navigation system is just a castle in the air.

On the basis of this first generation of dual satellite positioning, Han finally developed a real global positioning system. Their Beidou satellites have been continuously launched into the sky, first networking and applied to China, and finally extended to the whole world, becoming the second practical satellite navigation system in addition to GPS.

Xiong Guo's satellite is too short-lived and will be scrapped in a year or two. If you want to build a network, you have to launch it continuously. When Xiong Guo disintegrates and has no money, their network cannot be maintained and is paralyzed.

At that time, the Galileo satellite still didn't come out. They began to quarrel, saying that China occupied their frequency band. However, the international rules were who occupied it first. Their cunning was useless.

That is the parallel space-time of later generations. As for now, the Beidou navigation system of the Han Dynasty is incomparable. It is only in the 1980s, and the Beidou satellite has begun to go to heaven!

"Is this our first satellite?" Qin Guan asked.

"No, the first satellite has been in heaven. We have tested it for several months and think there is no problem. Now we are ready to launch two satellites with one arrow and two satellites, and network three satellites, so we can officially start the positioning test." in front of a large number of foreign personnel, president he began to introduce it. Anyway, this thing was originally intended to be made public, For the world to use.

Now, of course, I want to introduce it to you.

Qin Guan nodded: "call me when you launch. I must attend."

"President Qin, we also want to go and have a look at your launch procedures," swangeland said.

Other investigators were also in high spirits. Looking at their appearance, Qin Guan was also very excited: "yes, of course, no problem. We welcome them."

If it was in the past, it would certainly not work, because the launch of rockets belongs to the military, but now, the launch vehicle is going to the world. On the one hand, it is also necessary to establish a special civil company, and the relationship with the military will become weaker and weaker. In order to attract the attention of customers, why not take customers to have a look?

"It seems that you have mastered the problem of missile orbit change perfectly," said an eagle expert.

One rocket and two satellites means that the carrier rocket takes two satellites into the sky at the same time. After reaching space, the first satellite is released to make the satellite enter the first orbit, and then the rocket continues to change its orbit. After reaching another predetermined orbit, the second satellite is released.

In this case, it is almost the same as the trajectory change of a ballistic missile in space.

It is very difficult to intercept ballistic missiles. It is best to detect the trajectory from the take-off phase, so that it can be calculated. However, if the ballistic missile changes its orbit and direction in the air, the other party will not be able to calculate it, let alone intercept it.

This is also the most convenient way to deal with the anti missile system. The space technology of the Han country is indeed very powerful!

After all, there are many technologies that need breakthroughs. For example, launching two satellites at the same time must require greater thrust and high carrying capacity. Then, it is necessary to master the stable and reliable "star arrow separation" technology. When it comes out, it is not allowed to collide. It is also necessary to choose the most appropriate route to finally make the satellite operate stably in different orbits.

However, with the continuous development of computer technology in the Han Dynasty, such things that need large-scale computing can no longer be difficult for them.

"We are talking about rockets," Qin said. "We develop space technology for the benefit of mankind and for the development of economy."

Qin Guan immediately transferred the other party's topic. Look, didn't we develop ballistic missiles to develop current aerospace technology and serve all mankind?

"Is that the Long March 3? Is that the third-class hydrogen and oxygen fuel tank?" just then, someone shouted again.

In addition to the Long March 2 and the Long March 3 in the final assembly, the most special of the Long March 3 is that the hydrogen and oxygen engine is used at the top level!

Qin Guan is very satisfied. Now, the topic has finally changed. Let's introduce our long March 3. After all, many customers need to launch communication satellites in synchronous orbit. They can only launch by Long March 3. The third stage of this rocket is the latest technology that our side has mastered in recent years.

Liquid rocket engine uses high-performance liquid fuel and oxidant. Among all materials, liquid hydrogen and liquid oxygen are the most efficient. The engine using them as fuel is the most advanced.

Mastering the technology of hydrogen and oxygen engine is one of the symbols for a country to become a powerful Aerospace country. The development of high thrust oxyhydrogen engine is the development trend of liquid rocket engine technology at home and abroad.

When the Long March 3 was first launched, the old experts strongly demanded that it be launched. Now it has finally come out and become the symbol of a large Aerospace country.

There are many challenges. Apart from the processing of the fuel tank and the precision forming of large-scale complex curved surfaces, it is not easy, and welding requires technology.

Seeing that everyone was interested, president he introduced them.
