Traveling through the sword to engage in military industry.

This was no small matter. Ren Zhong spent more than half a year working hard in two worlds, and finally put the most important research sections of Qin's project on the right track. Judging from the progress, it would be no problem for the first nuclear submarine launched in the world of Liangjian to be launched.

According to the current plan, it will not be a problem to complete the sea trial by the end of 53. Even if some subsystems may need further debugging and optimization, it will be a huge achievement to be able to complete the sea trial before the Rogue Eagle Nautilus.

When our Qin-class Blackfish completed the world's first nuclear-powered voyage, even if it looked almost exactly the same as the Rogue Eagle's Ray-class submarine, ours came out first, so it would be a genuine product among nuclear submarines!
This is a big thing in the world of Bright Sword to justify the poverty and backwardness of Dongda University. Even if it means selling everything we have, we must do it first.

And Ren Zhong is not going to hide it. The first voyage after the trial will be a global free voyage! He will also show his head from time to time to take selfies!
With excellent diving depth and almost unlimited underwater diving ability, Ren Zhong does not believe that the world today can catch any trace of the Qin-class black fish.

Now Dongda has few hard weapons that can threaten the Rogue Eagle. If the Qin-class Blackfish can go along Hawaii, the Gulf of Alaska, the Arctic, turn to the Atlantic Ocean to Bermuda, the Gulf of Guinea, the Cape of Good Hope, and then enter the Indian Ocean and go around the Arabian Sea, Maldives, and Malacca to return to its home port, and wander around the world for a visit, when the photos of such a round-the-world voyage are released, I believe those who understand will understand!
The world is so big, I can visit wherever I want, this is the true style of a great country.

At this stage, for Ren Zhong, the only place where he can navigate freely is the sky, apart from the ocean.

Ren Zhong certainly did not forget the real sea of ​​stars.

In fact, since the liberation, one of the most important topics of the Communications Research Center has been to conduct research on the communication principles and prototypes of space satellite technology.

According to the C-band and Ku-band communication technologies purchased by Ren Zhong from the main world, after more than two years of hard work, he completed the research on the core technologies and prototypes of the ground station and simulated space repeater.

Of course, there are some technologies that cannot be completed in the Bright Sword world for the time being. For example, the solar panels used for power supply are flexible and stretchable panels made from monocrystalline silicon solar cells that Ren Zhong purchased from the main world.

It is not to say that there is no solar energy technology in the world now. In fact, monocrystalline silicon solar energy was invented in 1940. However, the first generation of solar monocrystalline silicon developed according to the technology of the world was too low in photoelectric conversion efficiency, with a photoelectric efficiency of only about 6%.

This technology was patented. However, it was still far from being practical solar energy, so Ren Zhong used the patented technology obtained from the main world to apply for the complete solar energy industry chain core patent set in the world of Sword and Fairy. In this way, from the perspective of the scope of patent protection, Ren Zhong basically registered the core technology of solar cells in an orderly manner.

Monocrystalline silicon and polycrystalline silicon manufacturing technology, battery cell manufacturing technology, battery component processing technology.
In terms of technical preparation, by the year 50, basically all the simulation tests of satellite technology on the ground will be fully tested, and several satellite products will be ready, just waiting for the successful research of the carrier rocket to launch the satellite into space.

At the Rocket Research Center, after completing the Dongfeng I, II and III generations, the accumulated technology can basically support the development into the sky.

Therefore, Ren Zhong purchased the Big Bear Cosmos rocket technology from the main world, and developed the first generation Long March 27 with reference to the Cosmos carrier rocket. The project research team spent a lot of time to master the research of AK185I nitrate and kerosene TM- propellants, but due to the outbreak of the peninsula war.

The mission to enter space was postponed, and it was unclear when the entire war would end. In order to offset the huge steel torrent of the Rogue Eagle, facing the war, the project team had to shift their focus from space exploration to prioritizing the "peace messenger" who could travel across continents!
Even if Ren Zhong thinks that the army can solve all the problems, he is still facing the comprehensive advantages of the Rogue Eagle's sea, land and air forces, and the J-5A and Dragon Tank II have not yet come out to gain an advantage.

What the top leaders most desire is not to travel into space, but to prepare asymmetric strike capabilities that can be used in times of crisis in the face of the war on the peninsula.

The most urgent and needed task is to successfully research and develop the strategic-level fifth-generation Dongfeng Express, which will carry peace missiles with a range of at least 8000 kilometers and can threaten the west coast of the Rogue Eagle. In this way, after setting up missile silos in the northeast corner, most areas on the west coast of the Rogue Eagle can be directly hit.

Of course, for the top management, the sixth-generation Dongfeng Express, which Ren Zhong had originally drawn up for them with greater strategic significance, is what they want most. A big guy with a range of at least 12000 kilometers and capable of carrying peace bombs is the real defender of peace!
Because within this range, it can completely cover all the major cities on the east and west coasts of Rogue Eagle.

Only with this killer weapon can we speak loudly without worrying about no one listening.

From a strategic perspective, Dongfeng Express, which has a global mission, has a higher priority than Big Black Fish!

Therefore, all the resources of Professor Qian's project team were invested in this work.

Now, Professor Qian's team has finally achieved the first goal and realized the fifth-generation Dongfeng Express. According to different payloads and propellant loading, it can now achieve a strike range of 8000 to 10000 kilometers through fixed launch silos. The equivalent of the warhead now ranges from 50 tons to 300 million tons, covering most of the Rogue Eagle territory.

Of course, the warhead with a range of 10000 kilometers will be half as small, basically only a small warhead of about one ton, that is, 50 tons of equivalent. Of course, compared with the first peace bomb, this power is already an order of magnitude larger, which is definitely a pain that no city can bear!

However, the unexpectedly quick end of the Korean Peninsula War, the signing of the armistice agreement, and the outstanding performance of the army and air force have made this weapon lose too much strategic significance. After all, the Rogue Eagle coalition can be severely rubbed in the air and on land, which greatly reduces the threat of the Rogue Eagle to the country.

We didn't even have the chance to play this trump card before the Rogue Eagles caved in and signed the peace agreement.

After the risk of the country being affected by the war was eliminated, Ren Zhong divided Professor Qian's team into two parts. One part continued to improve the research on intercontinental peace messengers. Next, they not only needed to hit from a distance, but also to be smaller in size, and preferably be able to achieve mobile combat!
This new type of mobile combat platform towed by heavy trucks or trains is the direction of future development of intercontinental missiles. As for fixed launch silos, it is enough for some of them to pose a threat. After all, these fixed places are easy to be discovered and become targets, and there is no way to hide.

The mobile type is different. It can follow the vehicle and maneuver around in a mysterious way, making it completely impossible for the opponent to guess its specific location, and its survivability is greatly improved.

However, there is no rush for these. After the fixed strategic nuclear deterrent force is established, the land-based mobile force can be slowed down a bit. After the maritime nuclear force is built up, the nuclear strike force with four-in-one land-based mobile, sea-based mobile and air-based mobile plus silos will be perfect!
Now we are moving forward step by step. For nuclear submarines that need to cruise around the world at sea, accurate positioning and real-time communication are indispensable at all times. Therefore, the importance of satellite positioning and communication is highlighted.

Therefore, Professor Qian and his team’s latest mission is to switch from intercontinental missiles to satellite launch vehicles, and to launch the satellites that have been prepared long ago into the sky.

Although the core technologies are similar, and there are many common technologies accumulated in rocket engine design, propellants and even positioning methods, launch vehicles and intercontinental missiles still have their own characteristics.

Generally speaking, launch vehicles are thicker and larger, and there are still differences in aerodynamics. However, with the high-performance computer simulation provided by Ren Zhong, these things were not difficult for Professor Qian and his team. After several months of design modifications, they quickly successfully modified the intercontinental missile into a completely new design of Long March 1 launch vehicle!
Jiuquan.

This is the most suitable place for launching satellites at Todai.

Here, the terrain is flat, the population is sparse, it is dry and rainy, and launch tests can be carried out about 300 days a year, making it an ideal place to launch spacecraft.

With his experience in the main world, Ren Zhong chose this place to build the first satellite launch center without hesitation.

Not only is it geographically advantageous, it is also a great place in terms of confidentiality.

Of course, Taiyuan has not given up on the second satellite launch center. After completing the first satellite center, the land acquisition and construction of the second center began. According to the plan, the first satellite launch center will naturally focus on launching highly confidential satellites.

The second satellite center focuses on civilian launches.

The position was determined from the beginning.

After all, most of the current aerospace industry is located in the north. In terms of transportation conditions and production coordination, the base in the north is more suitable for the development of the entire industrial chain.

On this day, Ren Zhong also came to Jiuquan, the first satellite base.

The launch of the first communications test satellite, Dongfang-10.1, by a Long March- carrier rocket was scheduled for October , which is also the National Day of the Sword World.

Early in the morning, everyone in the base was excited.

Professor Qian and Ren Zhong sat in the middle of the command room.

"Professor Qian, today is the day your daughter is getting married and heading for the stars and the sea. Are you nervous?" Ren Zhong asked Professor Qian beside him with a smile. "This is also the first rocket on the entire Blue Planet to go into space, and it is also the first experimental satellite for humans."

"Mr. Ren, to be honest, I am a little nervous, but not too much." Professor Qian looked a little relaxed and joked. "Before this launch, we have already completed a live-fire test from the desert to the Pacific Ocean, verifying our basic propellant efficiency and the controllability of the overall design. From a technical perspective, we have mastered the entire set of technologies.

We even produced five sets of similar products at once. If we need to use them, we can just inject fuel. Even if the first launch fails, we can quickly find the problem and launch the second and third time."

"In short, before the big black fish is launched, our global positioning system will be ready for it. This is thanks to the sufficient reference materials and sufficient funds provided by Mr. Ren. Our current scientific research work is the most relaxed and dynamic in the entire Blue Planet. If we want to follow the previous research methods, we have to start from prototype design, theoretical verification, prototype testing, first round of testing, second round of testing, and mass production. It will take more than 5 years."

"Now we can decide the production quantity according to the maturity of technology. Although there is a certain waste of resources, it undoubtedly greatly improves the efficiency of research and development. For a backward country like us, this is our opportunity to catch up with the world.

On behalf of all the researchers at the Rocket Research Center, I would like to express my sincere gratitude to Mr. Ren for providing us with such a unique and excellent research environment." At the end, Professor Qian sincerely took this opportunity to express his feelings.

"Professor Qian, you are too polite." Ren Zhong shook his head. They are such selfless and sincere people. If they were in the main world, they would only be seen in special areas of historical time and space. "You are the ones who did all the work. No one has ever complained about the achievements. You even need to keep your names secret. You are all unsung heroes. If we have to thank you, it should be me who thanks you, and the people who thank you. We were able to open the door to the world so quickly. You are the great contributors who have made an indispensable contribution."

"After completing the satellite launch mission, I would suggest that the confidentiality of the rocket research center be declassified to a certain extent. At least in terms of personal life, our scientists cannot just stay in the mountains for a long time. In the aviation research institute established in Beijing, everyone can take turns to work and live there for at least half a year. At least the family should be in Beijing, so as not to delay the next generation."

Professor Qian was stunned, his eyes moistened. He did not expect Mr. Ren to think so much about their project team members and take on more responsibilities.

You have to know that every member of their project team is a walking secret that matters.

However, as the head of the project team, Professor Qian knew that without a normal life, the lives of his team members would be extremely incomplete. Therefore, Professor Qian could not think of any reason to reject Ren Zhong's plan, and he had no words to express it.

A gentleman will die for his friend. With a leader like this, the only way to repay him is to work harder.

In fact, this is the most important reason why Ren Zhong came to the scene this time. He hopes to tell Professor Qian the good news in person so that Professor Qian can bring the greatest happiness to the team members at the celebration banquet!

The launch process was unremarkable, and the first experimental satellite was successfully launched into orbit without any major problems.

As a satellite whose main function is positioning and communication, in order to indicate the existence of the satellite, this experimental satellite has added a special shortwave transmission function, which is to play the national anthem to the whole of Asia at 8 o'clock every morning and the Internationale at 8 o'clock in the evening!
When the media overwhelmingly spread the news of the successful launch of the world's first human satellite, coupled with the fact that two songs could be received on a regular basis through the radio, public opinion exploded all of a sudden!
Reuters: "The Eastern Dragon has opened a window to the world"

Eagle Alliance: "The first step for mankind to conquer space"

Han Tong: "This time we Orientals win"

Kyodo News: "Todai's ambitions and space strategy"

Ren Zhong didn't care about all this. After the first launch was successful, he decided to launch all five satellites according to their distribution in the sky.

In order to achieve accurate positioning on a global scale, a complete navigation system usually requires at least 4 satellites. This is because by using 4 satellites, the three-dimensional coordinates (longitude, latitude and altitude) of any point on the earth can be calculated. This configuration ensures that signals from at least 4 satellites can be received at any location and at any time in the world, thereby achieving accurate calculation of the position1.

Although theoretically three satellites can be used for positioning, in practice, four or more satellites are needed to achieve real-time positioning and provide more accurate services. This is because three-dimensional coordinates are required to determine the position of a spatial point, and by measuring the distance from the receiver to at least four satellites, the precise position of the receiver can be calculated. In addition, the use of the fourth satellite can also determine the time parameters, thereby correcting the receiver clock error and further improving the accuracy of positioning.

Ren Zhong prepared a global positioning and communication system for Big Black Fish, which included a total of five satellites. However, he prepared for the risk of failure of one of them. At least the first generation of satellite communication and positioning could be achieved under the conditions of a four-satellite network.

Of course, if all five are successful, the signal reception conditions for the big black fish will be even better.

This time we were lucky and all five satellites were successfully launched into orbit.

In this way, the first generation of Oriental Satellite Network was formed.

Not only can it be used for military communications, it even has integrated bandwidth reserved for a live TV channel. In theory, live TV function can be achieved between any two points on the earth through a satellite antenna!

Towards the sea of ​​stars, the first step is very solid!
