I have to say that Qian Xuesen is shrewd, and his guesses and judgments about Guo Shucheng are basically not wrong, but he doesn't know that Guo Shucheng is fundamentally reborn, and he naturally knows the future very well, and "predicting" the future is naturally accurate.

The two quickly sat down in the reception room, Guo Zhuocheng asked the secretary Bian Liang to receive Qian Xuesen's secretary, and he personally poured water for Qian Xuesen to make tea, handed over fruits, and chatted with him.

Qian Xuesen took a sip of tea, took out a stack of materials from the briefcase he carried with him, and said happily: "Humble sincerity, come, come, give you some of the results we have achieved in the past two years." Haha, to be honest, I couldn't have imagined these results two years ago, it was really unexpected. ”

Guo Shucheng said with a smile while taking the information: "Professor Qian, you are too modest, right?" Last time, we used the Blu-ray cruise missile you developed and manufactured to hit Vietnam, but one hit was accurate, just like a long-range sniper rifle, and the accuracy was far beyond my imagination, and that was the best weapon for our army. Since then, I know that no matter what high-tech products you make, I won't be surprised. What is there that makes you so happy this time, ah, ah, we launched ......the Global Positioning Satellite? When was the technical problem of our high-precision spaceborne rubidium atomic clock solved? ”

Qian Xuesen looked at Guo Shucheng in confusion and asked, "Is it necessary for you to be so surprised?" Since we have put even such cutting-edge products as blue light cruise missiles on the battlefield, what is the launch of six positioning satellites? There are only six satellite groups, which is far from global positioning, covering the Asia-Pacific region and parts of the Middle East. Even if these satellites are not as advanced in technology as the resource exploration satellites and reconnaissance satellites we have launched, there is no need to make such a fuss. ”

Guo Shucheng sighed embarrassedly, and said in his heart: Yes. China has put into practical use even cruise missiles with such high accuracy, and it is really not worth being too surprised to launch a positioning satellite. You must know that in the previous life, China's cruise missiles really entered the practical installation of troops after 2005, and their surnames can be comparable to the current surnames.

Because China's cruise missiles in the real modern sense only started after the Gulf War in 99, the party and state leaders at that time were stimulated by the Tomahawk-like cruise missiles that the United States made a big show in the Gulf War and decided to develop them, at that time organized a scientific research group composed of elite scientists from all over the country, invested huge sums of money in the development of cruise missiles, and it took more than 10 years to make a breakthrough before the cruise missiles entered active service, and they did not participate in real combat after they were installed in the troops. There have only been a number of live-fire exercises.

The reason why it took ten years to make a technological breakthrough in the previous life is because the later development can be said to have started from scratch, and only absorbed part of the previous technology.

Compared with the fact that cruise missiles were put into service nearly 20 years ahead of schedule, and they directly entered actual combat and achieved brilliant results, the positioning satellites of this life are only 10 years ahead of schedule, and there is really no fuss.

Guo Zhuocheng smiled and said, "Wasn't I surprised that our missiles were all like tigers?" With the guidance of positioning satellites, our missiles are not yet where to hit? Not only can the surname be improved, but also the internal structure can be streamlined. What I've been worried about is the obstacle of high-precision spaceborne rubidium atomic clocks. ”

The high-precision spaceborne rubidium atomic clock is known as the "heart" of the satellite navigation and positioning system, which can provide a high-stability time and frequency signal for the satellite system.

In the previous life, because of the technical blockade carried out by the United States against China, China could not obtain relevant technology for a long time, and the rubidium atomic clock purchased from Europe could not meet the requirements of higher accuracy, so that after China's positioning test satellite was put into use, it could only be used for a long time, and could only do theoretical research. In the end, China was forced to conduct its own research and development, and finally developed a product with a similar level of accuracy as the United States, which allowed China to establish the Beidou navigation system.

Just like China's space technology, it has also emerged because of the US blockade, which has made it possible for China to have its own intellectual property rights, although China's technology is not the most advanced, but it is no longer controlled by others. Sometimes it's hard to tell whether the U.S. blockade is a good thing or a bad thing.

Qian Xuesen said: "The solution of the clock is really thanks to you, thanks to our YJ-0's outstanding watch in the Falklands War. Prior to this, we tried to propose to the United States the technology of transferring spaceborne rubidium atomic clocks, but they rejected it outright, saying that this was their core technology, not to mention that it would not be transferred to China, even their allies would not be able to get it, and they were not even willing to listen to our technical proposal. However, after our YJ-0 anti-ship missiles wiped out the British task force and inflicted heavy damage on the US fleet supporting the British, the United States relaxed its tone a lot, and the actual combat situation of our cruise missiles in Vietnam also reached the ears of the United States, and they wanted to know more about our missile technology and get our relevant secrets.

So China and the United States exchanged these technologies, and we transferred some of our missile technology to them, and they opened up a lot of restrictions on cutting-edge new technologies to us. Because the high-precision spaceborne rubidium atomic clock is the key technology we emphasize, they have to transfer this technology to us. With their technology, coupled with the technology transfer of satellite skills, the level of our satellites has leaped a step forward, not to mention that it is on a par with the United States, at least surpassing the technology of the Soviet Union. However, we still do not want to rely entirely on positioning satellites to guide all missiles, it is just a guidance method that we adopt. Honestly, is your opinion that all other means of guidance should be abolished? Medium and long-range missiles do not want other means of guidance? ”

Guo Zhuocheng hurriedly said: "No! No! I'm a layman, so I don't dare to talk nonsense about this. I just think that with this kind of guidance, combined with the number provided by the Earth Survey Satellite, our missiles will be more accurate. ”

"yes." Qian Xuesen said with a smile, "Don't be so nervous, we won't listen to you completely." Today, even if you strongly demand that our missiles maintain only one guidance method, we will conduct a careful study and cannot draw conclusions lightly. As a matter of fact, on the question of whether or not to simplify and reduce the guidance methods, we have conducted many rounds of arguments, and in the end we still believe that it is better to retain a variety of guidance methods at the same time, especially the strategic missiles that we use ourselves, and in case the United States or European countries carry out strong electronic interference on our satellites, or even use various means to destroy our positioning satellites, we will not be able to rest on our laurels, and we must have other guidance methods instead, such as customary guidance, radar guidance, infrared guidance, or television guidance, or even remote controlto ensure that our missiles will definitely hit the enemy's key targets. I have always believed that the guidance of ICBMs and carrier rockets, which have a bearing on the overall security of the country, must be all-round, and the enemy cannot fully interfere with or control them, even if the cost increases. ”

Guo Shucheng said seriously: "Yes, you think it very carefully. I just liked this kind of positioning and guidance. Sometimes one more redundancy is one more guarantee, and I'd rather spend a little more. ”

Qian Xuesen is a pure technical expert, and he did not care about Guo Shucheng's feelings, and also said seriously: "Yes, especially missiles carrying nuclear warheads, they must be foolproof." It is not at all enough to engage in one or two guidance methods, nor is it enough to evade interception by merely relying on orbit changes and multiple warhead launches; we must consider it comprehensively to make it impossible for the enemy to guard against it, to block it, and to stop it. ”

Guo Zhuocheng nodded and asked: "But the missiles exported to small countries should be simplified, the guidance method can be single, and the positioning and guidance method is good, which can save a lot of costs, and the strike accuracy will not only not be reduced, but may also be improved." ”

Qian Xuesen said with a smile: "It's really the same as what heroes see." We are ready to adopt the simplest satellite positioning method for all missiles exported to Asia, including the Middle East countries, and no longer retain the customary guidance system, because our positioning satellites have been able to cover this large area, and even if there is still a little bit of it that has not been covered, it will not be possible to cover it all by next year. As for the missiles exported from South America and Africa, we only use the customary guidance method, because our satellites have not been able to cover them in recent years. As for short-range missiles such as air-to-air missiles, they remain unchanged as they are, with infrared, and radar guidance. ”

This is not a deliberate attempt to frame the countries that purchase Chinese missiles, but because these countries are dealing with other countries, even if they are dealing with the United States, it is not China that will deal with the United States, so there is no big problem in adopting a single guidance method.

As long as China and the United States do not directly confront each other, the Americans will not risk offending China by forcibly interfering with China's positioning satellites, let alone destroying them. Many times the United States and China, a big country in the Middle East, fight to the death, in fact, it is just like an adult fighting with someone else's child, if it is beneficial to himself, he will help the people close to him, and if it is not beneficial to himself, he will come forward to persuade him, but the two adults will not fight for this.

In other words, as long as China and the United States do not fight in a big way, China's positioning satellites will always be effective, and those missiles equipped with satellite positioning guidance systems will be able to accurately hit the target, unless China's missiles themselves are not good, or even a simple interference can not be withheld.

…… In the materials provided by Qian Xuesen, Guo Zhuocheng has successfully developed many cutting-edge weapons, and China's killer weapons are becoming more and more powerful, and the combat effectiveness of the Chinese [***] team will become stronger and stronger.

It can be said that there are signs of full-scale development of China's military science and technology.
