For the domestic satellite system, Liu Yijiu must have an idea.

Moreover, many of them are necessary, and the sooner those functions are realized, the more obvious the improvement of the entire national defense strength. When the time comes, even the blackbirds of the US imperialists will not be able to go to the airspace of the republic twice.

The GPS system of the United States, which began to be built in the early eighties and was completed in 1994, consists of 24 satellites at an altitude of about 20,200 kilometers in outer space at an altitude of 60 degrees apart by 60 degrees of orbital distribution, and there are three active backup satellites in orbit, such a satellite distribution, so that the United States can observe more than 4 satellites anywhere in the world at any time! The whole system is dual-use, with a positioning accuracy of 10 meters. From the mid-to-late nineties, the second generation was studied with a new GPS system with 20 satellites added to it, with a positioning accuracy of 1 mm.

Russia's GLONASS global positioning system was tested by the Soviet Union in 1982, and between 1982 and 1985, 3 simulated satellites and 18 prototype satellites were launched for testing. Due to the poor level of electronics in the Soviet Union, the satellites were designed to last only one year, and the average in-orbit service life was only 14 months......

The GLONASS system began to be officially built in 1985, and in 1985~1986, 6 real GLONASS satellites were launched, even though there are very big improvements, the design life is still only two years, and the actual orbit is only 22 months......

In 1987, GLONASSS launched a total of 30 satellites, including early prototype satellites, and 9 satellites were available in orbit. Beginning in 1988, the Soviet Union continued to launch satellites, the service life increased to three years, and it continued until the collapse of the Soviet Union, and the global satellite positioning system was not completed. Finally, Russia took over the development and finally realized the normal broadcast of navigation signals by 24 working satellites in the space constellation on January 18, 1996, and the construction of the first-generation GLONASS global positioning system was completed......

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

China, on the other hand, started with the design of Beidou satellite navigation in 1994, and finally launched two geostationary satellites in 2000 and a backup satellite in 2003. The entire Beidou satellite navigation verification system has only been finalized......

Liu Yijiu couldn't tolerate such a thing.

Even if the satellite system is piled up with money, as the Soviet Union did, it must start construction early.

At the same time, China and the United States and the Soviet Union proposed a plan for the construction of a satellite positioning system, but it was not until the construction of the United States and the Soviet Union was completed that China began to verify the technology......

This affects not only China's technological development in this area, but also the research and development of many related technologies.

"That's what I think about our satellite systems. The use of two satellites for positioning proposed by Chen Lao is very good. After all, we don't need to care about other countries, we just need to be able to observe our whole country. It doesn't matter if the service life is short at the beginning, we can continue to improve it in later experiments. The only difference is to throw a little more money in! We have reduced a lot of the military's investment, and I think we are fully capable of supporting this plan......" Liu Yijiu first said about the issue of money.

It's the same in a war, the soldiers and horses are not moved, and the grain and grass go first.

The main reason why a large number of key national defense projects in the republic have been launched is because there is no money.

In order to implement the national policy of defense strategy, it is also necessary for the country to have a strong armed force. China will not compete for global hegemony, nor can it be without the power to protect itself.

Otherwise. The history of the Manchu Qing Dynasty will repeat itself in the past.

"For the function of the satellite, we not only need positioning, but also need to transmit communication signals, and at the same time, we also need the satellite to carry a high-definition camera to take pictures. It has a reconnaissance function, so that when the enemy invades, we can quickly detect it. In terms of civilian use, we can use remote sensing technology to detect environmental changes in our country and various natural disasters...... "Liu Yijiu knows that he wants to do it. It has to be clearly positioned from the start.

Otherwise, like the Soviet Union, many satellites are launched into outer space every year, but in the end there are not many that can be used, and the garbage in outer space is increased.

"Xiao Liu, are you too much of this function? In this way, how big are our satellites at a time when we have not made a full-fledged breakthrough in various related technologies? Moreover, remote control, this is also a very big project, we need to discuss with the satellite design Lao Sun, he is an expert in this area...... "Liu Yijiu's requirements are really too difficult for the current China."

The orbit selection of the satellite, the design requirements for the implementation of the satellite's functions, and even the launch vehicle that launches the satellite into orbit are all very high challenges.

They alone can't sustain this project.

Otherwise, these projects are not only for large countries to experiment, and small countries should not think about it at all.

It's a systematic project.

"This is natural, this project is a huge system work, and it is a long-term work, and the personnel required will not be less, and the research funds will not be less......" Liu Yijiu nodded.

At the beginning, he didn't remember who was the master of satellite design in China.

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

In 1967, China's first satellite, Dongfanghong, was launched at the age of 38, and Sun Jiadong served as the technical leader of satellite design. More importantly, he is the chief engineer of the entire Chinese lunar exploration program, and the construction of the lunar base is inseparable from his foundation.

If he is pulled into the Beidou system from now on, will China's lunar exploration program be able to start earlier?

Once the lunar exploration project begins, as long as China can get the spacecraft to the moon in advance, Liu Yijiu will have the means to carry out helium-3 research.

When the time comes, perhaps the oil that the whole world uses to pit the republic will become history!

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

Twenty years later, the lunar exploration project began, and thus the extraction of helium-3 began, Liu Yijiu felt that time was enough.

As a computer-like being that is a hundred years more advanced than modern times, he can completely enable the Republic to reach the scientific and technological system that his world once needed half a world to develop in these twenty years.

At the very least, there are a lot of detours that can be avoided.

"What? Such a satellite is a headache, the current domestic technology, you don't know, in order to achieve so many functions on a satellite, it takes a lot of energy and cost, the military will not agree...... "I didn't know what Chen Fangyun and others came to look for him, and Mr. Sun Jiadong, who was about to become the chief engineer of the Ministry of Aerospace Industry, couldn't help frowning and said.

The Americans have already landed on the moon, but China does not have a few useful satellites in space!

"What if the military agrees? Mr. Sun, do you think you can start this research work now? If the Ministry of Aerospace Industry finds it troublesome, you can lend us some people, and we will do ......it ourselves," Liu Yijiu adhered to the habit of plucking the feathers of geese, and once again opened his mouth to borrow someone from the Ministry of Aerospace Industry.

Sun Jiadong was much more reserved than Chen Lao, and he directly rolled his eyes at Liu Yijiu, and didn't care about the fact that he borrowed someone from the Ministry of Aerospace Industry and didn't pay it back.

After all, he's only engaged in technology.

Moreover, the personnel management of the Ministry of Aerospace Industry is not the responsibility of the chief engineer, let alone the deputy general manager. In other words, in addition to developing missiles, Liu Yijiu and his team did not develop in the direction of space technology and long-range strategic intercontinental missiles, nor did they get core talents from the Ministry of Aerospace Industry, so they did not have any deep hatred.

"Did you know, young man, that scientific research is not a dinner party! Even though it's just two satellites, that's to mobilize all the industrial systems of the whole country! Sun Jiadong said meaningfully.

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

Do you really think you don't understand anything?

"Mr. Sun, we are also for the military, and at present, our country is much worse than foreign countries, if we don't plan early for the development of high technology, we will be thrown behind more in the end. Back then, we launched Dongfanghong ...... without any foundation, "Chen Fangyun is now full of the development of the Beidou system.

"Yes, we can study the technology of landing on the moon while vigorously developing satellite technology...... "This killer feature is sacrificed, and I am afraid that you, the chief engineer of the lunar exploration project, will not be tempted?"

As long as you are a person in the space system, no one will be unmoved by the lunar exploration project.

Why can't the Americans, but not the Chinese?

Why were the Soviets able to build a space station in space, but not China?

"This matter can only be organized if the military comes forward, and no unit can do it." Sun Jiadong sighed, and then said with a wry smile at Liu Yijiu, "Don't talk about your Ninth Academy, you can't do it at all, unless the Ninth Academy can bear all the research funds......"

Liu Yijiu stopped talking.

It's not that the Ninth Academy can't bear this expense, but once it bears this expense, all their other projects, all of them have to be paralyzed.

"It's because the military has this intention that I came to you." Liu Yijiu said faintly.

He tried to insert a kick in it, but was pushed back before he could lift his leg.

Thinking about it, I also feel that the Ninth Academy should not participate in any project.

As long as they have the Beidou system, their weapons and equipment will be able to achieve better results.

Then you can take advantage of the opportunity of exporting the satellite system to make the Beidou positioning system cover the whole world in advance, without waiting for 2020, 40 years later! At the very least, if Nipudosan develops, China will build these ...... there (To be continued.) )
