C1397 Aerospace Experts

0To Qin Guan, his life had always been busy.

After returning to the capital, he only spent a day at home. The next day, Qin Guan came to the Ministry of Space.

Major Yang's report had been officially submitted. The higher-ups were very concerned about it. Now, Qin Guan needed to come and coordinate with the Ministry of Space. Here, Qin Guan finally met a large number of aerospace experts.

"President Qin, everyone has been looking forward to meeting you." Most of the aerospace experts present were not young anymore. Time had left a mark on their faces. When they were poor, they relied on themselves, struggled, and achieved zero breakthroughs one by one.

Now, when they found out that the Y Country had activated the Planetary War Plan, they were also excited. In this way, they would certainly be able to play a more powerful role in their domain.

As expected, the country would also have to make a space plan with equal harshness. Although the scale of this plan was not large, it was different from the plan of the Y Country. There was no science fictional space weapon or anything like that. However... The amount of investment needed would also be astronomical!

They were very excited.

"Hello, Old Sun." Qin Guan shook hands with everyone. "I wanted to see you in the past, but I never had the chance."

Elder Sun, one of the pioneers of Han people manufacturing satellite technology and deep space exploration technology. He had been in aerospace for 60 years and had developed 45 satellites.

The first Red Eastern Satellite was Elder Sun's masterpiece. Now, the first project that Qin Guan advocated was the satellite navigation system. Of course, Elder Sun was also the chief engineer.

Qin Guan had never seen them before, but he shook hands with everyone warmly. At the same time, he could also call out their names, which made them seem even more friendly. In fact, Qin Guan obviously relied on the help of his Spirit Focus scanning system.

These old experts were all famous!

"President Qin, regarding the satellite navigation system, after we received the instructions from our superiors, we carried out the initial debate, and the result of the debate was... It's very difficult to get this project started. It's far beyond our current standards. "

The satellite navigation system was not simple, it was in the west. It's also a long road that has been constantly developed. It took more than 20 years for the people of Y Country to develop. What about their own side? They didn't have any technological reserves right now, so they wanted to develop it all at once. This was absolutely impossible.

It had already passed the era where satellites were released. Satellite was very innocent. Satellite was placed on any front line, but for people like them who were really releasing satellites, they had to shrink back.

Of course, Qin Guan knew that this project was not easy. If everyone could easily develop this project, they would not have tried to work together with Europe back then, because they knew that their technology was lacking.

What was the result? Cooperation was impossible. That was why they buried their heads in their own research. This research was also done step by step. The first step was to set up a low difficulty double star position.

The principle of Twin Star Positioning was first proposed by the scientists of Y Country in 1982.

Compared to GPS, which could easily produce dozens of satellites, Twin Star Positioning only required two satellites in the stationary orbit of Earth. In order to be safe, they could also add a backup satellite. Its principle was very simple, with the known coordinates of two orbital satellites as the center. Each of them measured the distance from the satellite to the user terminal as a radius, forming two spherical surfaces. The user terminal would be on the arc of these two spheres.

However, the user would not be able to calculate it themselves. There must be a central station on the ground with an electronic high-distance map. Provides an uneven sphere with the center of the earth as the center and height of the sphere to the surface of the earth as a radius. By using mathematical methods to solve the intersection point between the circle and the earth's surface, the user would be able to obtain the user's position.

In other words, this kind of positioning was very simple, but compared to the GPS, it was two-way, and required a workstation on the ground. As for the GPS, as long as there is a satellite above the head that provides time information, I can solve it myself without external help.

"If we want to take things one step at a time, then let's start with a Twin Star Positioning, how about it?"

With his current level, if he wanted to break through in the direction Qin Guan suggested, it would be safer for him to get a Twin Star Positioning Technique first.

This was also a plan that they had discussed and decided on after a few days of discussion. It was to take things one step at a time, and it was impossible for them to reach the advanced level of the world in one go.

Qin Guan shook his head. "This kind of positioning is not precise enough. Moreover, it also needs to send signals, which is not conducive to stealth. Furthermore, it can only be regional navigation, so it is not suitable for our current needs."

The advantage of dual-star navigation was that it could be built into a system for regional navigation in a relatively short period of time with a lower cost.

However, compared to a real global GPS system, it has a lot of flaws, synchronous satellite orbit, it is destined to be unable to navigate the target at high latitude, and it is also impossible to navigate the other side of the earth... It was destined to be a regional navigation system.

If the progress was not high enough, it would be around 10 meters. The GPS signal positioning accuracy was at the Mi level. The GPS bomb that used this kind of navigation said that it flew over from the left window. It definitely wouldn't go in from the right window, which was quite sci-fi.

And the biggest weakness was that it wanted to send a signal... In the military, once a signal was sent, it meant that he had been exposed... Although it would benefit the world, one thing was certain: First of all, it is destined to be a military system, with it, low-cost joint attack ammunition, this kind of Precision Guide Weapon could be used extensively.

"But we don't have such high technology. To directly develop it into a global positioning system, that would be quite risky in terms of technology," Elder Sun said.

"Yeah, let's not talk about other things. Just say that our satellite needs a high precision atomic clock. We can't do it." Another expert said.2

For the accuracy of navigation, the most important thing was the time signal. This time signal could only be provided by the most precise atomic clock. Its accuracy could reach a error of 1 second every 200,000,000 years, with a slight error of a mile. The more precise the time was, the higher the accuracy would be.

Why did he have to work with the people of Europe in the past? It was because Western Countries monopolized the technology of the planet's atomic clock and implemented a ban on our country. Without this technology, there was no way to talk about navigation.

Later on, the country was self-reliant and worked hard. Finally, they successfully grasped the key technology. They even succeeded in reversing certain aspects. When the 17th satellite of the Big Dipper 3 was launched, it was the most powerful satellite in the Big Dipper 3 system with the most signal, the one with the biggest load, and the longest lifespan. Moreover, this satellite carried the leading rubium atomic clock. This made the satellite the time benchmark of the entire Big Dipper System, and its accuracy was increased by one to two times.

"What if I have a reference?" Qin Guan asked Elder Sun.
