Man-made satellite!
As something that has never happened before.
Although it will shock the world, it is just like that. After all, in terms of practical value, apart from promoting national power, it has little use at all - just like an expensive toy of a big country.
After all, honor is honor and reality is reality.
What will actually take humans to space?
It’s not who is first or who is second, but who has more practical value?
Human beings are always realistic after all.
What people care about is never who discovered something first, but who finally applied it to human life.
Not because it cares, but because this application affects everyone's life.
What kind of invention will be applied to everyone's life and change everyone's life? Hello
They are communication satellites, satellite positioning, meteorological satellites, remote sensing satellites... They are satellites with a wide range of application foundations, and only they can truly change human life.
As for many other high-tech things, they have nothing to do with most people.
In the era in which Li Yian lived, part of the convenience of life was brought by satellites.
What would happen without artificial satellites?
In the 21st century, people almost dare not imagine what it will be like, but for Li Yi'an, who is used to life in that era, he has fully felt the inconvenience caused by the absence of artificial satellites.
"So, the most important thing now is not to seize the first satellite, but the first communication satellite..."
Li Yi'an, who was leaning in front of the case, wrote in the notebook Wrote "communications satellite" and then said.
"What is a communication satellite...well, it should be a geostationary communication satellite! Yes, that's right, only through it can signals be transmitted to the whole world in real time."
Then Li Yian wrote down some of the key technologies on his notepad,
"Geostationary satellites need to be launched into a geostationary orbit 36,000 kilometers above the equator. Are there rockets with such powerful thrust in Nanyang now?"
After issuing this question, he continued to write.
“In order to launch communication satellites, it is necessary to develop a new, more powerful rocket, yes, that’s it.”
In the following time, Li Yian has been studying communications there Satellite, and looking through the information - of course these information were obtained after the system activated the skills. Now all he needs is to copy this knowledge.
"Geostationary satellite?"
Taking the information from Li Yian's hand, Yuan Jialiu said in a shocked tone.
"Nanyang has really entered space?"
Although he was shocked, Yuan Jialiu was not surprised. He also had a certain understanding of "Wanhu Corner" and knew that it was moving step by step. space. But he didn't expect to have entered space now.
“It is not that Nanyang is going to march into space, but that mankind will definitely march into space. According to the information we have, the Soviet Union is conducting research in this area. They will not only launch artificial satellites into space, but also Send humans to space.”
Although Nanyang has no information on this at all, standing on the shoulders of historical giants, Li Yi’an still knows the future very well.
"So, we must follow up, but we are not just to enter space, but to enter space and change human life, the Olympic Games..."
Looking at Yuan Jialiu, the first-class physicist in Nanyang Scientists, there are countless Chinese scientists whose talents have been buried in another world, and now, what Li Yian needs is to discover their talents.
"If nothing else happens, Chang'an will host the Olympic Games in 60 years. Now TVs have entered thousands of households. In 7 years, TVs will have entered the vast majority of households. But if not Satellites cannot carry out television broadcasts. During a major event like the Olympics, people all over the world cannot watch the broadcast of the games at the same time. Therefore, we need one communication satellite, no, three geostationary satellites.”
Then Li Yian explained what a geosynchronous orbit satellite is.
"Geosynchronous orbit communication satellite is a communication satellite launched into a circular orbit that is synchronized with the earth's rotation period, which is 23 hours, 56 minutes and 4 seconds. The orbital altitude of this satellite is 35,786 kilometers, and the orbital plane The intersection angle with the earth's equatorial plane is zero, that is, the satellite is launched above the equator and runs in the same direction as the earth's rotation. From any observation point on the ground, the satellite is stationary. If a communication satellite is sent to a circle 35,800km above the equator. In a circular orbit, it moves in the same direction as the earth's rotation, and the time it takes to orbit the earth is exactly the same as the time it takes for the earth to rotate once. This kind of communication satellite is called a synchronous communication satellite, also called a stationary communication satellite. Earth satellite. Global satellite communications can be achieved with three synchronous satellites. Two tangent lines are drawn from the geostationary communication satellite to the earth. The angle between the two tangent lines is 17.34°. Such a geostationary communication satellite can provide nearly one-third of the earth. Regional communications. If three geostationary communication satellites are launched 120° apart from each other, they can cover most of the world and achieve global communications..."
While Li Yian was explaining his idea, Yuan Jialiu looked at the information in his hand. Although he originally knew that Li Yian was a scientist delayed by politics, he never thought that Li Yian's achievements in many scientific fields were So deep.
“...There are several technical issues. The satellite must be fixed above the equator, so the latitude of the launch site must be as low as possible. This is our biggest advantage. The Wanhujiao Launch Center is located This geographical advantage near the equator is our biggest advantage in launching satellites. In addition, we must also develop a series of new facilities such as new ground measurement and control stations and maritime measurement and control ships. This is a huge system project, both in terms of hardware and investment. , there is no problem. In addition to official investment, Asia Television will also provide certain funds, including satellite development costs."
After that, Li Yian stared at Yuan Jialiu and said.
“The only question is, can our technical strength develop a communication satellite?”
In fact, this is what Li Yian is most concerned about. Although he can provide certain technical help, it determines the "short board effect" of technological development.
It’s only June of 1953!
Many basic sciences are still very backward, but they are not far behind. After all, mankind's first man-made communication satellite was launched in 1960.
"Well..."
Faced with your question, Yuan Jialiu did not answer immediately. Instead, he flipped through the information and thought about it. After a long time, he said.
"There are technical difficulties, and they are very difficult, but it should be able to be overcome. This requires the joint cooperation of many companies and universities, especially in electronics."
"There is no problem, no matter what is needed, all aspects will be comprehensive If you cooperate, I will let Qiu Hai connect with you and let him be your assistant."
The Qiu Hai mentioned by Li Yian is Qian Qiu Hai, the deputy director of the official secretary office. Although he does not seem to be well-known, he is. But he is the old man of the official residence. He can coordinate all departments on behalf of the official residence.
“Help me?”
Yuan Jialiu was stunned.
"Yes,"
Li Yian nodded and said.
"You are responsible for this project. Many people say that the technological development of Nanyang originated from the Third Reich, but..."
Looking at Yuan Jialiu, Li Yian smiled.
“Now, we need to prove to them that the Tang people are no worse than other people!”
"We are indeed no worse than them. In recent years, both the international students who have come to Nanyang from various countries and the talents we have trained ourselves are all outstanding."
In an instant, Yuan Jialiu felt the great responsibility, and he put down He said with the information in hand.
"The biggest difficulty in the entire project is the rocket. Can the rocket problem be solved?"
After thinking about it, Yuan Jialiu said.
“In other words, how far has our rocket progress?”
