Technology: The naughty kid ruined my college entrance examination, but I turned over to nuclear fus

Director Lin jumped up from the chair excitedly, only then did he see Lu Yu, who had just pushed the door in, and an embarrassed look could not help but flash in his eyes.

"Chief Engineer Lu."

"Did you finish calling? Hahaha, sorry, just now I was a little too engrossed, so I didn't notice your side.. Ahem.

He cleared his throat, hiding the embarrassed look on his face.

"It's okay, Director Lin."

Lu Yu smiled easily: "You can see it devotedly, that's a good thing." I'm bothering you, you don't need to say sorry to me.

"Oh, more than half an hour has passed."

Director Lin looked down at his watch and found that it had been almost half an hour since Lu Yu walked out of the office door just now.

His face suddenly became more embarrassed.

"Chief Engineer Lu, you won't already be here, waiting for me for half an hour, right?"

"Whatever."

Lu Yu smiled: "I just came in." Originally, I thought that the call took more than half an hour, and it was embarrassing for you to wait so long. I didn't expect you to be so engaged. "

Well, hahaha..." Actually

, ten minutes have passed since Lu Yu pushed the door and entered.

But in such a short time, I really don't mention it.

"That's right."

Director Lin suddenly thought of something and set his eyes on a large list of formulas and theories that Lu Yu had left on the whiteboard not long ago.

"Chief Engineer Lu."

"Just after you left, I've been studying what you left behind, as well as the idea you just came up with."

"I don't know if I study this carefully, but when I delve into it, it really scared me a lot!"

Director Lin's expression was very excited, and he quickly walked to the side of the whiteboard, and also took out a black pen:

"Your previous idea, didn't you rely on the strong power of our Mars rover to achieve a high-load communication network connection?" I thought about it, I think on this basis, we can actually build a special communication connection station. "

Look..."

he took a black pen and drew a rough sketch on the whiteboard.

It looks not only expressive, but also much clearer than some of the sketches that Lu Yu just left.

After all, age is here, and the pen power of this drawing is indeed much stronger than Lu Yu! Although the sketches left by Lu Yu on the whiteboard before look equally clear, the concept is somewhat abstract.

Let Director Lin be an insider like him, but he can understand it.

But another person, such as the young man who just sent him in, although he is also a researcher at the Zhurong-2 Research Center, but.... If he is allowed to come to see it, he can only see a half-understanding.

And Director Lin's sketch is different, even if it is a graduate student who has just graduated from a related major, he can understand one or two!

"Chief Engineer Lu, look at this general idea I just came up with, does it work?"

After putting forward the idea that he had just pondered for a long time, Director Lin suddenly turned his gaze to Lu Yu with a look of anticipation!

"It seems... Your thoughts coincide with mine!

"Director Lin!"

Lu Yu's eyes also revealed a light of surprise!

"Your idea is for the rover to use its own network of microsatellites to build a relay station between Mars and Earth to improve the quality and reliability of communication, which requires a relay station between Mars and Earth, that is, a device that can receive and forward signals."

"My original idea was that there were a lot of difficulties in this question. After all, building a relay station between Mars and Earth consumes a lot of resources. "

Launch costs, orbit control, maintenance support, etc... These are all things that have to be well considered. "

And one relay station may not cover all communication needs, because the Mars rover may move to the dead zone of the relay station or lose line of sight contact with the relay station."

"Therefore, we may need a more flexible, economical and efficient way to achieve communication between Mars and Earth."

Lu Yu took a deep breath and continued

, "So,

what is the solution?"

"I actually wanted to say at the beginning that we can use the built-in microsatellite network, that is, form a group of small, lightweight, low-cost artificial satellites composed of a group of networks!"

"Look..." Lu

Yu directly followed Director Lin's sketch and continued to draw!

"We can build a distributed microsatellite system in Mars near-orbit." The electronic messages sent by this satellite system cover part of the Martian region! He

roughly added his thoughts on the whiteboard!

Director Lin's expression suddenly changed subtly!

"Chief Engineer Lu, you... Have you thought of this method for a long time?

He asked slowly.

"Well, this was my idea at the beginning, and I was going to say it right away, but that call... Interrupted some of my train of thought.

"But I really didn't expect that since Director Lin, since you followed my previous thoughts, you also filtered out my later thoughts!"

"What a hero sees!"

Lu Yu said with a smile.

"Sure enough!"

Director Lin also smiled, but a complicated look flashed in his eyes!

He originally thought that the method he came up with came from a burst of inspiration. Because of this, he was just so excited!

It's like a student encountering a problem while doing a problem. I didn't have a clue how to think about it before, but after pondering for a long time, I finally burst out of inspiration to solve this problem, which must be so excited that I jumped up directly!

But... He didn't expect that this in itself was Lu Yu's original train of thought!

In other words, the idea he spent so long coming up with was actually just following the formula that Lu Yu had just left behind, and going on.

However, at this thought, although Director Lin's face was not as excited as at the beginning, it was also quite happy.

Since this is Lu Yu's idea at the beginning, it proves .... Lu Yu must not only have one prototype now, but has a complete idea!

"Chief Engineer Lu, you continue."

"I listen."

Director Lin returned to his seat and turned his gaze to Lu Yu with a look of full attention, waiting for his next speech!

That look, it didn't look like a huge aerospace engineering chief engineer, but like a student who listened carefully in class.

"Okay, then I'll continue."

Lu Yu smiled slightly, and then brushed the thoughts in his mind.

Originally, if it hadn't been for that call, he would have said all these thoughts smoothly in one breath!

But even if the train of thought is interrupted, the knowledge brought by those systems is always like a soldering iron, imprinted in Lu Yu's mind!

So.. In just ten seconds, he spoke again:

"Since we have to rely on the Mars rover, that is, the communication network that comes with our Zhurong-2 to build a microsatellite communication system."

"These microsatellites must then be deployed at different orbital altitudes, angles and velocities to form a distributed, dynamic, self-organizing system!"

"Only in this way can the Mars rover communicate with Earth stably through the microsatellite network."

"That is, the signal is sent to the nearest or most suitable microsatellite, which then forwards the signal to other microsatellites until the target Earth station or other Mars rover is reached..."

Director Lin fell into deep thought.

Sure enough, as he guessed, since this was a plan that Lu Yu had originally made, it was far from being just a scrawled prototype diagram, but a complete detailed plan!

Compared with the idea he had just "comprehended", the idea proposed by Lu Yu was undoubtedly more perfect!

Undoubtedly, this will save a lot of time for the next research process!

However....

"Chief Engineer Lu."

After half a ring, he slowly spoke:

"That is to say, we need to launch a series of microsatellites to ensure the stability of the communication network according to the law you gave next?"

"Yes."

"If you want to rely on the Mars rover's own communication network, then... Microsatellite networks are absolutely indispensable.

Lu Yu bowed his head slightly and said.

"If it's just a microsatellite network, it's okay to say. Over the years, our dragon country's satellite launch technology has become more and more perfect, and it has even been able to achieve large-scale commercial use.

"In terms of time, it should be enough."

After Director Lin secretly calculated in his heart, he immediately smiled with relief.

Microsatellites are artificial satellites with masses between 10 and 100 kilograms.

They are often standardized or modular in design to reduce development costs and time, and improve reliability and compatibility.

They also take advantage of the miniaturization and performance improvements of electronics to achieve more functionality and higher efficiency.

"Over the years, China's satellite launch technology has been greatly improved. Although the launch schedule of Zhurong-2 is relatively anxious, it should be timely to launch several groups of microsatellites before this.

"Chief Engineer Lu, your idea is very good!"

Director Lin's eyes were full of admiration!

Compared with traditional satellite technology, microsatellites do have many unique advantages!

The weight is greatly reduced, which means that the launch cost is also greatly reduced, and it can be launched with smaller and cheaper launch vehicles or as secondary loads, which also means shorter launch preparation times!

Now Zhurong-2's research time is already tight.

It would certainly be good to be able to launch this group of satellites faster!

At the same time, microsatellites have greatly reduced development costs compared with traditional satellites, and commercial or open-source platforms and components can be used to reduce R&D risks and cycles.

At present, this technology has been commercialized on a small scale in the Dragon Kingdom!

Just like some rich people, celebrities, and even launch microsatellites signed by themselves or their companies to increase their own or their company's popularity!

Moreover, microsatellites are more versatile and flexible, using software-defined or reconfigurable technologies to adapt to different scenarios and needs!

In Mars orbit, which is far from Earth, it may be able to perform better!

"I originally thought about launching traditional satellites to build stability."

"However, according to your mention, it is indeed better to use microsatellites."

Director Lin looked at Lu Yu and said with a slow smile.

"Well, microsatellites are also more efficient, and after using intelligent or autonomous technologies to improve operational performance and management level, they should make the communication network we build more stable and avoid being affected by sandstorms!"

Lu Yu said with a smile.

The two people talked freely for a long time about the microsatellite network.

Finally, the common conclusion is that if you really want to go to Mars against a sandstorm, using microsatellites to build a communication network is definitely the most suitable way, there is no one!

"Our Zhurong-2 team, the strength of soft science should not be weak, and it is more than enough to build a microsatellite connection network."

Lu Yu said with a smile.

Director Lin bowed his head slightly and nodded:

"Our Zhurong-2 soft science team uses top university team applications, and should be able to build a microsatellite connection network that is enough for our Mars rover to be used flexibly."

"Since our general direction has been set."

"Then it's a matter of specifics. Chief Engineer Lu, your side is..."

He turned his inquiring gaze to Lu Yu.

If it is normal to say, since the general direction has been set, then the next thing to deal with is the launch of microsatellites, which should be the details of the specific connection network!

But the problem is... Lu Yu's identity is not just the chief engineer of Zhurong No. 2!

He is also the head of the Exoskeleton Equipment Research Center!

Therefore, whether Lu Yu will continue to stay in the Zhurong No. 2 Research Center next is still unknown.

"Since our big plan has been decided, then I have to go back for the time being."

Lu Yu's eyes showed a hint of apology, and said helplessly:

"The research project in my hand has now entered the white-hot stage, and it really can't leave me for the time being." This way.... The launch of microsatellites, I think there is no participation of me, in fact, it has little impact. "Good

!"

Director Lin also did not have ink: "Then leave it to me."

"Chief Engineer Lu, what you came to talk to me about today is enough for our project team to go far!" It can be regarded as making me really understand what it means to listen to Jun Yi and read books for ten years, hahahaha. A

smile flashed in his eyes.

For Zhurong-2 Research Center.

The next specific network construction problem is not too difficult! As long as you can continue to follow the ideas proposed by the landing language, it is enough!

"Hmm..."

Lu Yu yawned and looked down at his watch, his eyes showing a look of exhaustion.

In the past two days, he has been running back and forth in various research institutes, busy for so long, and he is also exhausted to the extreme.

"Then I'll go back first."

After Lu Yu said hello to Director Lin, he did not stay for a long time, and returned all the way to his professor's apartment.

The other side.

Kyoto Airport....

"Ladies and gentlemen, your flight..."
