C980 How about Satellite Navigation

Prof. Lin had been waiting for Qin Guan, because he had received orders from the navy that President Qin would solve the problem of precise navigation. He had been waiting since then, all the way until now.

Prof. Lin knew that Qin Guan was very busy, so he did not take the initiative to look for him. Today, he saw Qin Guan, which was both within his expectations and beyond his expectations.

Prof. Lin came to the office. At this time, there was no one else inside. He smiled and poured tea for Qin Guan, which made Qin Guan feel flattered.

"Prof. Lin, you rest. I will do it myself." Qin Guan said.

Qin Guan respected these old professors the most. At that time, they wholeheartedly wanted to return to the country. They gave up the superior conditions overseas and resolutely returned to the country to contribute their lives to the motherland.

Even later on, they were persecuted in that chaos, and they still didn't change their original intentions.

It was precisely them that allowed the country to truly become strong. Otherwise, he would not have been able to lead the entire country's development with just a system.

As for those people who had worked overseas for their entire lives, dedicated their youth and wisdom to foreign countries, and returned to the country to enjoy life when they were old, Qin Guan despised such people in his heart.

Prof. Lin sat down and said, "President Qin, we now know about the floating top of the liquid. If the precision is not high enough, we will also exert force on the top of the laser top. But now, foreign countries have sealed off our technology. We can't see the real thing nor do we have the processing ability. Therefore, it's very difficult to continue improving the precision. "

This was the main problem that Prof. Lin was facing. These problems were no longer a problem for Qin Guan.

"I have some technical information here that was brought over from the secret battlefront. Now, I will hand it all over to Prof. Lin." As Qin Guan spoke, the Elementary Scholar pushed a large box into the room. Inside the box was the technical information that Qin Guan had exchanged.

Prof. Lin pushed up his glasses and opened the box. He first picked up the topmost box and looked at it carefully.

They were all in foreign languages. To Prof. Lin, this was nothing. Prof. Lin had studied his PhD in Y Country in the past. Now, after Prof. Lin read a few pages, he put them down. "That's right. There are detailed explanations of the various principles behind the laser top. It is consistent with our research, so it can't be wrong. However, if we want to make it, the precision of the processing is not high enough. "

The laser top's precision was high enough. At the same time, processing it required sufficient precision. This was also the biggest problem that troubled them.

"In terms of processing, we can bring it to Grassland City, where the North Heavy Truck Factory is located. There is a specialized processing workshop with high precision. It can also accept external processing tasks. " Qin Guan said, "If there are any difficulties, you will need specialized processing equipment. Inform me again."

There was no need to worry about processing. He had the Weapon Data Cemetery to exchange for these materials. There were also machine tools cemeteries to exchange processing equipment. After all, in the future, the laser top was too ordinary, even an aircraft model. Maybe they were all laser gyroscopes inside.

"We will study and process these materials, there might be half a year to a year's time" Prof. Lin said, "President Qin, thank you for your support!"

"Fortunately, our electronic technology has developed very quickly. There will definitely be no problem with processing the signal of the laser top. If you need advanced computers, you can say hello to Han Chip Technology Company."

Only the top was not enough. They needed to install the acceleration meter and the gyroscope on the carrier. He needed to calculate the real-time posture matrix in the computer, which was to calculate the relationship between the carrier coordinate system and the navigation coordinate system. Then, he could convert the acceleration information of the carrier coordinate system into the information under the navigation coordinate system, and then carry out the navigation calculation.

"Thank you, President Qin." Prof. Lin did not hesitate. "Then give us ten computers, how about it?"

The computers in Han Chip Technology Company had always been in short supply, even if it was mainly supplied to the country. Many departments were also fighting for the computers. Beijing Airlines University had already been allocated a batch. But they were all given to the Computer Institute. Prof. Lin did not touch them.

Qin Guan smiled. "This is nothing. Unfortunately, no matter how advanced the laser top is, there is still a error."

The error could only be reduced, but the error could not be eliminated. This was the basic physics principle.

"Yeah, so, on the basis of inertial navigation, we still need to superimpose Starlight Navigation."

In terms of sailing, Starlight Navigation had been used for hundreds of years. Observing the stars in the sky and then navigation was the most common method.

However, this kind of ancient method could not satisfy modern needs.

"Navigation through the stars in space, there are conditions and limitations. If we can use satellites to achieve navigation, that would be great." Qin Guan said.

Qin Guan's words made Prof. Lin's eyelids twitch.

Prof. Lin was already old. He was close to seventy years old. He should have been able to live comfortably for a long time. It was only because he couldn't stay idle that he taught his students and continued scientific research. Of course, he knew about the development of the world in terms of navigation.

YCountry had already started to develop a global satellite positioning system.

Satellite navigation technology was a technology that utilized Navigation Satellite to navigate the ground, ocean, air, and space users.0

Using the sun, moon, and other natural celestial bodies to navigate had a history of several thousand years. Although the idea of man-made celestial bodies to navigate had been proposed in the latter half of the 19th century, but in the 1960s, artificial satellites developed. It was only then that it began to be realized.

Although the GPS system was known by later generations, the Y Country Navy's demand for the GPS system was quite urgent. Therefore, in 1964, they built the "noontime" satellite navigation system and handed it over to the navy. In 1967, they started to use it for civilian use.

The trajectory of the satellite could be determined by the Doppler Frequency Shift curve detected by the satellite. If one knew the precise trajectory of the satellite, they would be able to determine the location of the receiver. This was the principle of satellite navigation.

The Y Country first started this project, and it was also to solve the problem of the precise positioning of the North Pole Star nuclear submarine when sailing in the deep sea and carrying out military missions. It was named "Lunchlight Plan."

In 1973, the Y Country started to develop the "Navigation Star" global positioning system.

After more than ten years of development, the GPS global positioning system was finally developed. To truly cover the entire world, that was already twenty years.

Of course, the Han Navy also had urgent needs, but everyone knew that with the technology of Han Country, they could no longer rely on it.

At this time, Qin Guan brought up the technology of using satellites to navigate. It was time for Han Country to develop this technology!

Qin Guan was well aware of the strategic significance of building a global Navigation Satellite to a country. It could be said that it could be compared with rockets and nuclear weapons, becoming a national weapon!
