1Big Dipper Navigation Satellite!

In the past, Qin Guan had only used one of the destroyed GPS satellites in the satellite cemetery. Here! This was definitely an extremely cheat-like action. After the exchange, Qin Guan didn't ask about the follow-up work. He left it all to the experts who studied the satellite.

To create this kind of satellite, it required a lot of effort. What kind of algorithm should be used for navigation, how to transmit signals, how to do the most precise atomic clock on the satellite, how to do it, there were too many techniques that needed to be overcome.

Back then, it was precisely because the difficulty of the Navigation Satellite was too great that Han Country wanted to contact Europe, hoping to join their Galileo Satellite Navigation Plan.

But what was the result?

The Galileo Satellite belonged to Europe. Those fellows were all high and mighty. If Han Country wanted to enter, they could. How much funds did they need? However, they could not obtain any technology!

After a few years of bickering, the Han Country finally realized that advanced technology could not be relied on by others. They had to work hard on their own. Therefore, the Han Country made up their mind and embarked on the path of self-research and development.

Because the difficulty was too high, the Han Country first set up a Twin Star Positioning Station. This method required a computing station on the ground and a user to send a message to space. This way, it would be easy to expose it.

Although there were all kinds of flaws, they were still developed by themselves. Finally, he could vent his anger. At this time, Europe was still arguing with each other, their Galileo GPS system... It was just an empty building.

With the foundation of the first generation of double star positioning, Han Country finally developed a real global positioning system. Their Big Dipper Satellite kept flying up into the sky, first forming a network and using it in the country. Finally, it expanded to the world and became the second usable satellite navigation system other than the GPS.

Not counting the ones in Bear Country, the lifespan of the satellites in Bear Country was too short. They would be destroyed in one or two years. If they wanted to set up a network, they had to continuously launch them. When Bear Country broke down, they would have no money. Their network would not be able to be maintained, and they would be paralyzed.

At that time, the Galileo satellites still had not come out. They had started a war of words. It was said that Han Country occupied their frequency band. However, the international rule was that whoever took over first belonged to the person. It was useless for them to be so cunning.

It was still the Parallel Spacetime of the future generations. As for now, no one could compare with the Big Dipper Navigation System of the Han Country. It was only the 1980s, but the Big Dipper Satellite had already started to soar into the sky!

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

"No, the first satellite is already in the sky. We have been testing it for a few months. We think there is no problem. Now, we are going to use Double Arrow. Launch two of them, and the three satellites will form a network. Then, we can officially start the localization test. " In front of all the foreign staff, Dean He began to introduce them. In any case, this thing was originally intended to be made public. It had to be used by the whole world.

Now, of course, it had to be introduced to everyone.

Qin Guan nodded. "Call me when the launch is happening. I must participate."

"President Qin, we want to go too. We want to see your launch program." Swann Grand said.

The other inspectors were also in high spirits. Seeing their expressions, Qin Guan was also very excited. "Sure, of course, no problem. We welcome them."

If it was in the past, it definitely would not have been possible. Because the launch of the rocket belonged to the military. But now, the rocket launchers are heading to the world, and in this aspect, they are also going to set up a specialized civilian company. The relationship with the military will become increasingly thin, in order to attract the attention of customers, so what if he brought customers to take a look?

"It seems that your side has already perfectly grasped the problem of the missile's derail." An expert from Y Country said.

One arrow and two stars meant that the rocket carried two satellites into the sky at the same time. After arriving in space, the first satellite would be released, allowing the satellite to enter the first orbit. Then the rocket would continue to change orbit and reach another predetermined orbit. The second satellite will be released.

If that was the case, it would be almost the same as when the Ballistic Missile achieved a change in orbit in space.

It would be quite difficult to intercept the Ballistic Missile. It would be best to test the trajectory from the takeoff section. Only then could the calculations be calculated. However, if the Ballistic Missile changed its trajectory in the air... If it changed its direction, the other party wouldn't be able to calculate it. It would be even more impossible to intercept it.

This was also the most convenient way to deal with the Anti-missile System. The spatial technology of Han Country was indeed very powerful!

After all, there were many techniques that needed to be broken through. For example, launching two satellites at the same time would definitely require a greater thrust. It required a very high load capacity. And then... You need to master a stable and reliable "Star Arrow Separation" technique. When you come out, you can't collide with it, and you need to choose the most suitable route. Finally, the satellite would be able to operate stably in different orbits.

However, with the continuous development of the computer technology in Han Country, this kind of thing that required large-scale calculations was no longer difficult for them.

"We are talking about rockets now." Qin Guan said, "We are developing space technology to benefit mankind and to develop the economy."

Qin Guan immediately changed the topic. Look, didn't we develop the Ballistic Missile to develop the current Aerospace Technology and serve mankind?

"Is that the Long Conquering Three? Is that the third level hydrogen fuel tank?" At this moment, another person shouted.

Other than the Long March 2, there was also the Long Conquering Three. The most special thing about the Long Conquering Three was that at the top level, it used a hydrogen oxygen engine!4

Qin Guan was very satisfied. Now, the topic had finally changed. Let me introduce our Long March 3 to everyone. After all, many customers need to launch communication satellites. They could only rely on Long Conquering Three to launch in the synchronous orbit. The third level of this rocket is the latest technology that our side has only mastered in recent years.

The liquid rocket engine used high-performance liquid fuel and oxygen serums. Among all the materials, liquid hydrogen liquid oxygen was the most efficient. Using them as fuel engines was the most advanced.

Grasping hydrogen and oxygen engine technology was one of the signs of a country becoming a powerful aerospace country. The development of high-thrust hydrogen oxygen engine was a trend in the development of domestic and international liquid rocket engine technology.

When they first started the Long Conquering Three, the old expert had strongly requested for it to be developed. Now, it had finally come out and became the symbol of a large aerospace country.

There were many challenges involved. Just the processing of the fuel tank, the large complex curved surface, and the welding process required a lot of technology.

Seeing that everyone was interested, Dean He went over to introduce them.
