Super military empire

For domestic satellite systems, Liu Yijiu must have ideas.

Moreover, many of them are necessary, and the earlier the realization of those functions, the more obvious the improvement of the overall national defense strength.At that time, even the black bird of the U.S. emperor wants to wander twice in the airspace of the Republic.

The American gps system, which began construction in the early 1980s and was fully completed in 1994, is composed of 24 satellites distributed on six orbital planes separated by 60 degrees in outer space at an altitude of about 20,200 kilometers, and there are three active backups. Satellites are in orbit. This distribution of satellites allows the United States to observe more than 4 satellites anywhere in the world and at any time!The entire system is dual-purpose for military and civilian use, with a positioning accuracy of ten meters.Beginning in the mid-to-late 1990s, the second generation of new gps systems with 20 satellites added, with a positioning accuracy of 1 mm.

The GLONASS Global Positioning System of Russia has been tested by the Soviet Union since 1982. Between 1982 and 1985, 3 simulated satellites and 18 prototype satellites were launched for testing.Due to the poor electronic level of the Soviet Union, the designed service life of these satellites is only one year, and the average service life in orbit is only 14 months...

The construction of the GLONASS system began in 1985. From 1985 to 1986, 6 real GLONASS satellites were launched into space. Even with very large improvements, the design lifespan was still only two years, but only 22 in orbit. month……

In 1987, the GLONASS system launched a total of 30 satellites, including early prototype satellites, and 9 satellites are available in orbit.Beginning in 1988, the Soviet Union continued to launch satellites, and the service life increased to three years. It lasted until the Soviet Union disintegrated, and the global satellite positioning system was not completed. Finally, Russia took over and continued development, and finally achieved a full space constellation on January 18, 1996. The 24 working satellites broadcast navigation signals normally, and the construction of the first-generation GLONASS global positioning system is completed...

These are the first two countries in the world that have a global satellite positioning system.China is the third.

In China, the Beidou satellite navigation design began in 1994, and finally two geostationary orbit satellites were launched in 2000, and a backup satellite was launched in 2003. The entire Beidou satellite navigation verification system was finally completed... …

Liu Yijiu could not tolerate such a thing.

Even if the satellite system is piled up with money like the Soviet Union, the construction must be started early.

China has proposed a satellite positioning system construction plan at the same time as the United States and the Soviet Union. However, it will not begin to verify the technology until the construction of the United States and the Soviet Union is completed...

This impact is not only the technological development in China, but also the research and development of many related technologies.

"For our satellite system, I think so. The two satellites proposed by Chen Lao for positioning are very good. After all, we don't need to control other countries, we just need to be able to observe our country. It doesn’t matter if the initial service life is short, we can continue to improve it in subsequent experiments. The only difference is to spend a little more money in! We have reduced a lot of the military’s investment, and I think I am fully capable of supporting this plan..." First of all, I will talk about money.

The same is true in wars, where the soldiers and horses are not moved, and the grain and grass go first.

The main reason for the discontinuation of a large number of key defense projects in the Republic is that there is no money.

To implement the national policy of a defensive strategy, the country must also have a strong armed force. China will not strive for global hegemony, nor can it be without the power to protect itself.

Otherwise, the history of Manchu Qing will repeat the same mistakes.

"For the function of satellites, we need not only positioning, but also the transmission of communication signals. At the same time, we also need satellites to carry high-definition cameras to take pictures and have reconnaissance functions, so that we can quickly discover when the enemy invades. For civilian purposes, we can use remote sensing technology to detect our country’s environmental changes and various natural disasters..." Liu Yijiu knew that to do it, it must be clearly positioned from the beginning.

Otherwise, just like the Soviet Union, many satellites are launched into outer space every year, but in the end there are not many useful, which increases the garbage in outer space.

"Xiao Liu, do you have too many functions? In this way, when our various related technologies have not achieved comprehensive breakthroughs, how big is our satellite? Moreover, remote control is also a very large project. We need to discuss with the old Sun in satellite design, he is an expert in this field..." These requirements of Liu Yijiu are really too difficult for China at present.

The choice of the orbit of the satellite, the design requirements for the realization of the satellite function, and even the launch vehicle to launch the satellite into the orbit, are all very high challenges.

They alone cannot support this project.

Otherwise, these projects are not only large countries that can conduct experiments, and small countries don't even think about it.

This is a systematic project.

"This is natural. This project is a huge systematic work, and it is still a long-term work. It needs not less people, and research funds must not be less..." Liu Yijiu nodded.

At the beginning, he didn't think of who is the best satellite design player in China.

But when I heard Chen Fangyun talking about Old Man Sun, I suddenly remembered a person known to all national defense science and technology workers in their era, and even all Chinese people-Sun Jiadong!

In 1967, China's first satellite-Dongfanghong, 38-year-old Sun Jiadong served as the head of satellite design technology.More importantly, he is the chief engineer of the entire Chinese lunar exploration project. The construction of the lunar base cannot be separated from his foundation.

If he is brought into the Beidou system from now on, can China's lunar exploration project be started earlier?

Once the lunar exploration project is started, as long as China can allow the spacecraft to reach the moon in advance, Liu Yijiu will have a way to start research on helium-3.

At that time, perhaps the oil used by the entire world to pit the Republic will become history!

It will be a full twenty years before China begins to import oil on a large scale from the world.

In twenty years, the lunar exploration project was started and the extraction of helium-3 started. Liu Yijiu felt that there was enough time.

As a computer host-like existence in a world that is a hundred years more advanced than modern times, he can completely allow the Republic to reach the technological system that once his world took half a world to develop in these two decades.

At least, you can avoid many detours.

"What? Such a satellite is a headache. You don't know the current domestic technology. To achieve so many functions on a satellite, it will take a lot of energy and cost. The military will not Agree..." Originally, Mr. Sun Jiadong, who was about to become the chief engineer of the Aerospace Industry Department, couldn't help but frowned and said that he didn't know what Chen Fangyun and others were looking for.

The Americans have landed on the moon, but China has few useful satellites in space!

"What if the military agrees? Sun, do you think we can start the research work in this area now? If the Ministry of Aerospace Industry finds it troublesome, we can lend us some people and we can do it ourselves..." Liu Yijiu inherited the goose crossing The habit of plucking hair once again borrowed from the Ministry of Aerospace Industry.

Sun Jiadong was much more reserved than Chen Lao and they directly rolled his eyes at Liu Yijiu, and did not care about his borrowing from the Ministry of Aerospace Industry and not repaying it.

After all, he is only engaged in technology.

Moreover, the personnel of the Ministry of Aerospace Industry are not in charge of the chief engineer, let alone his vice president.In other words, in addition to missiles, Liu Yijiu and the others did not develop in the direction of space technology and long-range strategic intercontinental missiles. They did not recruit core talents from the Ministry of Aerospace Industry, and they had no deep hatred.

"Young man, did you know that scientific research is not a dinner party! Although it is just two satellites, it must mobilize all the industrial systems of the entire country!" Sun Jiadong said meaningfully.

"For the country's national defense and security, how about mobilizing the whole country?" Liu Yijiu also rolled his eyes.

Do you really know nothing?

"Mr. Sun, we are also doing this for the military, and our country is already much worse than foreign countries. If we don’t plan early in the development of high-tech, we will eventually be left behind. What were we back then? Dongfanghong was launched without the foundation..." Chen Fangyun is now full of the development of the Beidou system.

"Yeah, we can definitely study the technology of landing on the moon while vigorously developing satellite technology..." This killer feature comes out, and you are afraid that you, the chief engineer of the lunar exploration project, will not be tempted?

As long as it is a member of the aerospace system, no one will be indifferent to the lunar exploration project.

Why can the Americans but the Chinese not?

Why can the Soviets build a space station in space, but China can't?

"This matter can only be organized by the military. No unit will work." Sun Jiadong sighed, then said with a wry smile at Liu Yijiu, "Don't talk about your Ninth Academy, it won't work at all, unless the Ninth Academy can Undertake all research funding..."

Liu Yijiu stopped talking.

It's not that the Ninth Institute cannot afford this cost, but once they have undertaken this cost, all of their other projects have to be paralyzed.

"It is because the military has this intention that I am looking for you." Liu Yijiu said quietly.

He wanted to get a foot in it, and finally he was pushed back before he could raise his leg.

Thinking about it, I also feel that the Ninth Institute should not participate in all projects.

As long as they have the Beidou system, their weapons and equipment can achieve better results.

Then you can fully use the opportunity of exporting satellite systems to allow the Beidou positioning system to cover the world in advance, without waiting for 2020, which is 40 years later!At least, if Neptune develops, China will build these...
