A big country of aerospace with black technology

Jiangcheng, 101 Satellite Research Institute.

The official approval of the low-orbit satellite communication network project made this unit, which was not well-known nationwide, suddenly become a rising star in the eyes of everyone.

After all, the first phase of the satellite communication network project has invested 10 billion yuan, and the subsequent capital investment may reach tens of billions.

If the money leaks out a little bit, it will be enough for others to eat for a long time.

As a research and development unit of communication satellites, the 101 Satellite Research Institute can get even more research and development funds.

However, this is just an outsider's opinion, after the 101 Satellite Research Institute received the development work of the satellite.

Basically, everyone in the institute has a pessimistic attitude.

After all, if they really want to meet the satellite performance indicators announced by Sun Hongtao, it will be too difficult with their current technical reserves.

For this reason, Zhong Zixin, the director of 101 Satellite Research Institute, who is in charge of satellite development, pointed out the difficulties in satellite development at the meeting meeting for the initial construction of the entire satellite communication network:

"Mr. Chen, it's not that I deliberately exaggerated the difficulty, it's that the research institute doesn't have that much ability!"

Chen Zhongyan naturally knew that there were many difficulties in the development of communication satellites based on the current domestic technical level.

Otherwise, the previous Satcom Company would not have faced all kinds of troubles and asked Hughes Company, which has a bad relationship with us, to develop communication satellites for us.

But it is not impossible to say whether it is possible to develop a satellite that can be used with the current domestic technology, but in terms of various performances, there may still be a certain gap compared with the international advanced level.

However, the gap between yes and no is still quite large, even if it is barely usable, it is not impossible.

But Mr. Chen would not just listen to the cry of 101 Satellite Research Institute. After all, everyone has difficulties:

"If there is any difficulty, tell me, maybe everyone can solve it for you!"

The above has estimated the current technical difficulty of this project, knowing that it is very difficult for various technologies to meet the standards.

Therefore, various support policies, or financial support, are very strong.

But as the director of the 101 Satellite Research Institute, Zhong Zixin actually knew the duration of this project, and it didn't take long.

I don't quite understand some of the situation here, so when I saw Mr. Chen's words, I thought he was talking ironically, and I was a little embarrassed.

"Or I'd better not say it, we are not so sleepy."

"Just say what you want! What nonsense!" Chen Zhongyan was not used to his temper at all, and said in a slightly aggressive tone.

At this time, Zhong Zixin also felt that he seemed to have no choice but to say nothing, so he broke the jar and said:

"Old Chen, I don't know who proposed this satellite communication network plan."

"But from the perspective of our satellite research, this plan is really a layman!"

"With so many low-orbit satellites, not to mention the possible orbital dangers, the rocket capacity alone cannot launch so many satellites in a year, right?!"

Hearing what Zhong Zixin said, Zhang Xingyang and Chen Zhongyan looked at each other and laughed loudly.

Zhong Zixin didn't know what kind of riddle these two people were playing, and he was a little confused, just when Zhong Zixin was still wondering if he said something wrong.

Chen Zhongyan stopped laughing, calmed down his somewhat disturbed breath and said:

"Let Dean Zhang, who is in charge of the rocket part of the entire system, explain this to you!"

Zhang Xingyang, who hadn't smiled so happily for a long time, took a deep breath:

"Director Zhong, please let me introduce to you the latest development of our Rocket Research Institute, Hongyan-1!"

"Using an advanced liquid fuel propulsion system with a take-off thrust of 1,210 tons, the low-earth orbit carrying capacity has reached 26 tons, and the entire first-stage part of the rocket is recyclable, which can minimize the cost of rocket launch."

"It is precisely because of the successful development of the Hongyan rocket that the higher authorities will agree with us to carry out the construction of the entire low-orbit satellite communication system."

Zhong Zixin opened his mouth wider the more he listened, as if he was listening to some sci-fi story, until Zhang Xingyang finished speaking, he was still dazed for more than ten seconds.

After a while, Zhong Zixin came to his senses and said:

"Dean Zhang, are you sure you're not telling me some science fiction story?"

Zhang Xingyang naturally understood the shock in the heart of those who had never seen the Hongyan rocket when faced with such an industrial miracle.

After smiling, he said, "Director Zhong, less than a month ago, we just sent two satellites with a weight of 3,700 kg and 3,000 kg to the SSTO orbit."

"I think you, as a satellite researcher, should be able to understand what this data means!"

Of course Zhong Zixin knows that the carrying capacity of the rocket to the SSTO orbit is almost only a quarter of that of the low-Earth orbit.

If the SSTO orbit carrying capacity of a rocket can reach 6,700 kilograms, then it is not difficult for it to reach 26,000 kilograms when launching low-Earth orbit satellites.

Zhong Zixin slowly pushed back his jaw that was so shocked that it was about to dislocate.

Faced with such a successful rocket research institute, Zhong Zixin was a little embarrassed to talk about the hardships his own satellite research institute was facing.

After all, it is also facing difficulties. The Rocket Research Institute can make a rocket that meets the project requirements. Why can't your Satellite Research Institute?

Many times people live just for a face.

In order not to lose face, Zhong Zixin had no choice but to lower his head in shame and fell silent.

In the end, it was Mr. Chen who said: "Then what a small family attitude, and any difficulties in the research will be raised, and we will solve them for you if we can solve them ourselves."

"If it really doesn't work, I'll help you coordinate from above and help you solve it!"

Zhong Zixin didn't care too much about face at this time, after all, it seemed that the determination to promote this project was quite high.

It's not like you can hide by pretending to be a quail like this.

"Mr. Chen, I'm not complaining. You also know that our current technical reserves are like this, which is still far behind the international advanced level."

"At present, we have deficiencies in signal compression, transmission, decoding, etc. in various frequency bands."

"Moreover, judging from the final planning of the entire project, after the final project is completed, there will be a maximum of 10,000 satellites in the country, but they will have to handle communication requests from so many people."

"How can the satellite have such a large processing capacity?"

"These problems are difficult to solve by our satellite research institute alone!"
