Zheng Hao actually knew Liu Yijiu's whereabouts.

At present, all kinds of projects have been on the right track. Liu Yijiu's energy is mainly devoted to more advanced intelligent program development. What he uses is a supercomputer specially made in the base according to his requirements.

Li Rui threw the two children to her mother, and he led a group of women's soldiers in the base to start building supermarkets outside. No one disturbed Liu Yijiu.

In this way, it entered the end of April of 1990.

"Director Liu, our first Beidou system experimental satellite and the rockets launched are all ready. It is expected to be launched at 4:35 am on May 1st..." The news was sent by a special person from the aerospace base next to the base to tell Liu Yijiu.

Liu Yijiu was stunned, and then a smile appeared on his face, "Are the rockets and satellites ready?"

"Yes, it is currently scheduled to be launched at the Jiuquan Satellite Launch Center. Our leader asked me to ask you if you have time to visit..."

"Yes, if you don't have time to try this, you have to squeeze out time to visit!" Liu Yijiu immediately put down his work, "Tell them that I'm going to go to the satellite launch base now."

Anyway, his job is not something he can do in a short time.

He has always been looking forward to the Beidou satellite system going to the sky, and even paid a lot for this. It is impossible for him to be away from the scene when the first experimental satellite went to the sky.

"There must be no mistakes in this satellite launch. We have been working for this project for so many years!" Liu Yijiu first went to the Ministry of Aerospace Industry, and Qian Xuesen was holding a meeting on this satellite launch.

When he saw him arrive, the receptionist took him directly to the conference room.

This project gathers almost all the top satellite experts and rocket engineers in China.

Although rockets are civilian, the technology above is no different from military strategic missiles.

The first experimental satellite and the first supporting Long March 3A rocket invested more than 2 billion yuan in research and development.

"Many projects in the Ninth Hospital are currently waiting for our satellite system, so no mistakes are allowed. Various inspections before launch must be carried out more carefully. Otherwise, once the launch fails, it will cause a serious blow to our next work!" Chen Fangyun, who is responsible for the entire satellite system, has become older in recent years.

This experiment used satellite system is to use the use of two stationary orbit satellites in 1983 to achieve regional positioning and navigation functions. The main purpose is military use.

In the past few years, in order to prove, the functions of Zhongxing One and Two communication satellites were specially added, and experiments in this area were conducted to prove that the technology was completely feasible.

With the capital investment of the Ninth Hospital, the development of the Beidou system was achieved several years ahead of schedule.

"It's okay to fail immediately. This is related to the national defense cause. If it fails, it's impossible to start over. There is no need for everyone to put too much pressure on you. During this period, the Ninth Hospital has made good returns. After negotiations in the hospital, it is ready to increase the investment of about 5 billion yuan in the Beidou system again! So, in the next few years, what you need to do is to constantly design new satellites, manufacture them, produce rockets, and then send our satellites to the predetermined orbit. What we need is not only a regional positioning and navigation satellite system, but global ones!" Liu Yijiu also gave a big gift to aerospace.

As time goes by, the money for selling Dongfeng has been almost exhausted by aerospace.

At the same time, because of the full efforts of the economy in China, there has been not much military production in recent years. In addition, the Ninth Academy has robbed a large amount of scientific research funds, and many military factories are transforming. Many people who cannot transform because of their special role are just struggling.

Aerospace really feels unsustainable.

Especially after they invested in the Beidou system.

Satellite systems, new rockets, control technology, etc. have to be more advanced and complex, and there are too many places to invest.

"Old Chen, please introduce the development plan of our Beidou satellite system to Director Liu." Qian Xuesen looked at Liu Yijiu with a smile on his face.

Chen Fangyun nodded, and then used the projector he had obtained from the Ninth Hospital to play the slideshows that had been prepared long ago.

This surprised Liu Yijiu.

It seems that I have prepared for it.

Before he could react, Mr. Chen began to introduce it.

"Based on our current technical foundation and budget for funding, in order to develop our aerospace communication technology well and avoid the waste of research funds caused by blind research, after discussion and demonstration by the entire Ministry of Aerospace Industry and many comrades of the Chinese Academy of Sciences, we have formulated the following plan. Overall, the Beidou system is carried out in three steps to realize the global positioning navigation function. Before January 1, 1991, the first system will launch two regional satellite positioning navigation communication systems that can perform active positioning on the system stationary orbit, and at the same time, launch a backup satellite... The second step is to realize regional passive positioning before 1995... Global passive positioning is achieved in 2004..."

Mr. Chen's introduction made Liu Yijiu feel a little lost in an instant.

It's exactly what Beidou took before.

However, there have been changes in time.

In the original world, the Republic finally completed the Beidou global satellite navigation system, which was not completed until 2020.

If this plan is achieved, the Republic's satellite system will cover the world 16 years in advance.

In this way, the Republic's technology in this area will develop faster, and even the plan to launch the Tiangong space station can be 16 years ahead of schedule, and landing on the moon can also be 16 years ahead of schedule. Even the time to establish a lunar base will not have to wait until 2046.

"With our current technical conditions, what are the main difficulties in achieving such a goal? The performance of satellites is the most critical determinant. I believe that our rockets can accurately launch our satellites to a predetermined orbit. Satellite control systems, long-range remote sensing technology, etc., all require more advanced technical support." Liu Yijiu is not a fool. The other party introduced this, which must be coordinated by the Ninth Academy in many aspects.

During the cooperation between the Ninth Academy and Aerospace, technical cooperation has become increasingly close in recent years, and both parties have also understood the technical level of the two parties.

He had proposed before that it would increase its investment by about 5 billion yuan, but he was not prepared to recover these funds.

It is impossible for the other party to know before.

He said that he would give money, but it would be 5 billion. He still introduced it like this. Then, the biggest problem is in terms of technology.

"Indeed, our technical conditions are still far from this. However, these plans are based on our own technological development and the technological development of the Ninth Academy. We need Ninth Academy to support computer technology, materials, top-level mechanical manufacturing, and even automation control..." Qian Xuesen said to Liu Yijiu.

The fields he mentioned are the most core of the Ninth Academy.

He knows Liu Yijiu's personality and it is hard to say whether he will agree to support it.

"None of these aspects is a problem. Whether it is aerospace or we, they belong to the country, not to any private person. Our goal is always, that is, to make our country's national defense cause as solid as a rock!"

Liu Yijiu's words instantly received countless applause from the old men.

The thunderous applause made Liu Yijiu feel a little embarrassed.

He said with a blushing voice after the applause stopped, "Let me introduce the situation of our satellite and rocket this time."

Liu Yijiu needs to obtain the performance parameters of this satellite and rocket, and then use it to compare the performance of the satellites used by the country to launch these satellite systems at that time with the rocket. Only in this way can the entire domestic scientific and technological foundation be evaluated and based on this, we can measure whether the Beidou satellite system can be implemented in three steps.

"This satellite is the first of our Beidou satellites, and it also bears the experimental nature. It is directly Beidou-1... This satellite has a remote sensing function, which can remotely sense the ground, and through signal processing, the captured pictures are fed back to the ground control center... Due to the resolution problem, the accuracy is not very good. After all, this is an experiment... In addition, the satellite has a positioning function, using the same signal source specially designed on the ground, which can realize remote communication, and use the regional pictures taken by remote sensing to contact the control center, and implement the communication positioning function... At the same time, it can position and navigate the devices equipped with signal receiving equipment..."

"Didn't we launch the first meteorological satellite, Fengyun 1, in 1988? Isn't that remote sensing technology so good?"

Liu Yijiu frowned.

Remote sensing technology is an indispensable part of military satellites.

"At present, the Ninth Hospital uses Yun-1 as a platform, and the remote sensing technology is much better than Fengyun No. 1. If you use this as the basis..." Chen Fangyun looked at Liu Yijiu.

"No problem. The cooperation in this regard is not only the cooperation between our two companies, but also those with this technology such as the Chinese Academy of Sciences have cooperated." Liu Yijiu nodded without hesitation to agree.

Remote sensing technology, this is something that is inevitable.

Especially in future military satellites, if you see the situation on the ground through the sky, in which case the pattern of war will change again.

With such technology, the squadron can not only use this technology to assist the attack, but also use this technology to allow the army to simulate fighting in the enemy's situation.
