A big country of aerospace with black technology

Dongfeng launch site, on the desolate Gobi Desert.

Looking from a distance in the sky, two very small figures were walking slowly in the desert.

The two are Chen Zhongyan, chief engineer of Beidou Navigation Engineering, and Zhang Xingyang, director of the Rocket Research Institute.

In order to promote the development progress of the Beidou satellite, Chen Zhongyan's gray hair has turned gray a lot.

"Old Chen, you have to take care of yourself!"

Zhang Xingyang glanced at the other party's hair, and tried to persuade him.

"Ham, it's nothing." Chen Zhongyan stroked his hair messed up by the desert wind and sand.

"As long as I can make Beidou, even if I die, I will have no regrets!"

The wind and sand from the desert entered Zhang Xingyang's eyes, making him want to cry.

Why do I often have tears in my eyes, because there are too many people in this country who regard death as home and sacrifice their lives for the country!

Sensing that Zhang Xingyang beside him had turned into silence, Chen Zhongyan smiled:

"There's no need to be so sad, people are always going to die."

"Heavier than Mount Tai, or lighter than a feather!"

"It's worth dying for a cause you love!"

Seeing that the topic seemed to be going to a strange place, Chen Zhongyan quickly brought back the topic:

"Stop talking about me, let's talk about you?"

Zhang Xingyang was a little puzzled, what can I say?

Looking at Zhang Xingyang who looked puzzled, Chen Zhongyan laughed and said:

"Xiao Zhang, you are not young anymore, have you considered starting a family?"

To say that in this era, the most troublesome thing for Zhang Xingyang is definitely the elders' urging marriage!

As long as it is an elderly person, after knowing that Zhang Xingyang has no partner, he will almost always remind him.

Zhang Xingyang has never been so desperate when facing so many scientific research problems.

Now it's a real experience.

"Old Chen, I have no plans to start a family yet." Zhang Xingyang said a little embarrassedly.

"Now I still want to put all my energy on work."

Chen Zhongyan can also understand that this age is when the scientific research ability is the strongest, and there is nothing wrong with wanting to focus on work.

So I didn't worry about it too much.

"Xingyang, do you really think that space-based communication networks have much greater advantages than ground-based communication networks?"

This incident was the root cause of the two of them going to the desert.

Only in the desert of no one can we talk about these contents with confidence.

"It depends on your view of the future situation."

"Do you think there will be a world war starting with a nuclear war in the future?"

Zhang Xingyang did not directly answer Chen Zhongyan's question, but asked him his views on the future world situation.

Although I don't know the reason for Zhang Xingyang's question, Chen Zhongyan still answered the question very seriously:

"Judging from the current world situation, it is unlikely that an all-out war will break out."

"The situation of future wars may also be dominated by local wars or proxy wars."

Although Chen Zhongyan does not have any position in the military, at his level, he is qualified to know information about many international situations.

Therefore, he has a relatively thorough view of the international situation.

"If you think so, then I can tell you clearly."

"The advantages of space-based communication networks are greater than those of ground-based communication networks!"

"First of all, the space-based communication network will not be affected by all kinds of bad weather, and secondly, it can build a nationwide communication network in a very short period of time, solving communication problems in many remote areas."

"Finally, the construction of a space-based communication network can drive the development of our manufacturing industry, especially the high-end manufacturing industry!"

Zhang Xingyang mentioned the advantages of three space-based communication networks to prove that space-based communication networks are better than ground-based communication networks.

But Chen Zhongyan is very clear that if relying on these reasons alone, it will be difficult to convince those big bosses who really make decisions.

Abandon the mature ground communication network technology route, and switch to the space-based communication network technology route that is still in the development stage.

They must see the stronger advantages of space-based, so that they may take the risk of trying space-based communication networks.

"Do you think there are any advantages?"

Zhang Xingyang could feel that Mr. Chen seemed not interested in his previous answers.

At this time, Zhang Xingyang seemed to understand that what Chen Zhongyan wanted to know might be more about its military application.

At this time when the smoke of the Cold War has not completely dissipated, when every country builds a satellite system, it must consider its military use.

For example, missile guidance, monitoring of enemy forces, etc. must be taken into consideration.

Why at this time, the missile guidance accuracy in or within is poor, and the inertial guidance equipment is backward, but it is very difficult to improve the accuracy of inertial guidance itself.

If our own satellite navigation system is completed, the missile can also adopt a dual-guidance mode, using a combination of inertial guidance and satellite guidance to improve the strike accuracy of the missile.

"Old Chen, you know better than me the military use of the satellite navigation system, so I won't talk about its advantages in navigation."

"The military use of the low-orbit satellite communication network is different from Beidou."

"I think the advantage of the low-orbit satellite communication network is more of an advantage in data link transmission."

The data link mentioned by Zhang Xingyang is still a technology that is being explored in China at this time.

So it was easy to arouse Chen Zhongyan's interest, and asked enthusiastically:

"Expand and talk!"

"Take the information warfare that the military is advancing now as an example. In the future information warfare, the command center must be able to see the situation of each force on the command map."

"It is even necessary to be able to see the situation of every tank, every armored vehicle, and even every individual soldier on the front line!"

"And all of this requires our equipment, or the ability of individual soldiers to access the rear information network."

"And the foundation of all this is the establishment of a wartime communication network!"

"The traditional form of radio communication, because it requires high-power equipment, is not only easy to be spotted by the enemy, but also limited by terrain and weather."

"In some locations with complex terrain, it is easy to be unusable."

"The space-based communication network does not have such troubles when accessing data."

"Especially in areas with complex terrain, satellite communication has stronger advantages."

Because it is actually just a private conversation between the two now, Zhang Xingyang also expressed another consideration:

"The high-quality orbits that can be used in the Earth's low-Earth orbit are very limited."

"If we don't occupy it at this time, it will be difficult to occupy it after everyone starts to develop space technology!"

The evening wind on the Gobi, as the sunset gradually sinks into the horizon, becomes bigger and bigger.

Chen Zhongyan narrowed his eyes gradually and fell into silence.

Seeing that Mr. Chen stopped talking, Zhang Xingyang played another card:

"After the low-orbit satellite communication is completed, only a part of the satellites need to be equipped with high-resolution cameras or infrared surveillance cameras."

"We will be able to detect the movements of Yingjiang's warships and fighters around our country very well!"

"In the future, if we want to get out of the first island chain, there will inevitably be a fierce confrontation with Ying Jiang!"

Chen Zhongyan dusted the sand on Zhang Xingyang's overalls with his hands, and instead of continuing to talk about the satellite communication network, he said lightly:

"Let's go back."

However, Zhang Xingyang can feel that Chen Zhongyan has basically agreed with Zhang Xingyang's vision for the low-orbit satellite communication system.

The back is blocked, it may not be released until tomorrow, there are only two chapters today
