Chapter 497
“Train of thought…”
Lu Yu frowned, and after pondering for a while, he said
with a slight bow: “Director Lin, in fact, I have a preliminary idea now.”
“But whether it works or not depends on what we know about Mars.”
“Oh, and what does that have to do with what we know about Mars before?”
Director Lin asked with a curious look.
“That’s right.”
“Didn’t our observatory draw a rough map of Mars before?”
“I think that since we want to prevent our Mars rover from losing contact under the influence of sandstorms through technical means, then this Mars map must come in handy!”
A smile appeared at the corner of Lu Yu’s mouth, and he continued: ”
As long as some data on this map is accurate enough.”
“We can use this map to build a general network, cover the part of the Mars rover where it lands, and then pass through…”
“The Mars rover can use its own cameras, radar, magnetometers and other instruments to observe the surrounding terrain and geomorphological features, match with the pre-stored Mars map, and calculate its approximate location.”
“Under the premise of having this position, even if it is temporarily lost with us, it can rely on its own positioning system to ensure that there is no problem with its own direction!”
Lu Yu roughly said his thoughts!
After listening, Director Lin also briefly fell into thought.
“In other words, we have to rely on the autonomous positioning system of the Mars rover to compensate for the signal interference problems that may be caused by dust storms?”
“But this can solve a momentary worry, but there is no way to solve the problem for a long time!”
Director Lin frowned and said:
“If this scheme is used, in a short period of time, the Mars rover can indeed operate normally under the interference of sandstorms.”
“But even if the positioning system is accurate.”
“After all, after such a long distance, every time after a small positioning, there will inevitably be a certain error.”
“In the beginning, the error may be small! But step by step, relying on autonomous positioning so much, the error will accumulate more and more, and if the Mars rover flies into which ditch at that time, wouldn’t it be…” Director
Lin’s face showed a look of embarritassment.
“Director Lin, I understand your concerns.”
Lu Yu smiled slightly, and said with a relaxed face: “This concern of yours, in fact, I already considered this plan when I came up with it.
“Our ultimate goal is definitely to strengthen the communication capabilities of the Zhurong-2 Mars rover.”
“As for this plan… After all, it’s just a transition.
“After all, no matter how strong our Mars rover has wireless communication capabilities, under the interference of strong sandstorms, it is difficult to ensure that there is a 100% possibility that it will not be lost!” You can only try to avoid this problem of missing contact!
“And the autonomous navigation system can provide a certain guarantee for our Mars rover in a short period of time of missing contact!”
“It’s certainly not used for a long time!”
After listening to Lu Yu’s explanation, Director Lin probably understood what he meant!
Simply put, this is a backup means to turn this autonomous navigation system into a Mars rover!
Once the problem of the loss of the Mars rover is caused by the violent interference of the sandstorm, the autonomous navigation system can be immediately activated to ensure that in the process of losing contact, the Mars rover can still temporarily maintain stable work!
As for the long-term arrangement, we still have to find a way to strengthen the signal communication problem!
With the communication help of Blue Star, this Mars rover can be regarded as truly “rooted”!
“Chief Engineer Lu, according to what you said, have you already thought about how to strengthen this communication capability?”
Director Lin suddenly thought of something, and a smile appeared on his face again!
Since Lu Yu mentioned that this was just a backup means, then he must have a confident idea and already had a means in his heart that could be used conventionally!
“Sort of.”
Lu Yu didn’t have any need to hide it, and said with a smile: “My idea can only be regarded as a prototype for the time being.”
“But I think it’s very feasible.”
He came to the whiteboard again, took out a pen, and while writing and drawing, explained:
“Director Lin, you also know that our Mars rover can use its own antenna or laser communication equipment to send signals to the orbiter or the earth and request location services.”
“If you can receive a reply signal, you can further correct your position and direction according to signal strength, delay, angle and other information…”
“And because of the existence of strong electromagnetic dust storms on Mars, once it enters the core area of the dust storm, it will have an unpredictable impact on the strength and angle of our signals!”
“The data sent to Blue Star by our Mars rover is likely to be sent to which corner because of this impact!”
“It’s also one of the main culprits in our communications chaos.”
Director Lin listened like this, without interrupting or asking any questions of his own.
After all.
What Lu Yu just said is only the basic communication principle of the Mars rover, and the basic reason why electromagnetic dust storms will have an impact on the Mars rover!
These theories, let alone him.
Even if you grab a small assistant in Zhurong No. 2 base, you can understand the meaning of Lu Yu!
Director Lin also understands that the main play must be later!
Really!
After explaining the most basic principles, a smile appeared on Lu Yu’s face!
“Director Lin, you should also know.”
“The process of our communication with the Mars rover is mainly the rover-satellite-blue star. These three points are carried out in a one-line way.
“The reason why it is so susceptible to interference is also because for the Mars rover, whether it is a satellite or our blue star, the distance is a little too far.”
“In that case, can we let the Mars rover use its own network of microsatellites to build a transit station between Mars and Earth?”
Having said this, Lu Yu revealed his truest thoughts!
“Oh, the transit station?”
Director Lin froze slightly!

Professor of
Longguo Renmin University
on the other
side, our next laser puncture experiment must be tested in the field!”
“Otherwise… This can’t go on!
Several doctoral students surrounded their Professor Wang, their eyes full of doubts: “Why is this laser plasma experiment suddenly sealed?” There is not even a way to apply for it.
“If it goes on like this.”
“The progress is really unbearable!”
Their words are full of anxiety!
When you get to the doctoral level, the pressure is far greater than when you are a master, and the so-called academic garbage thesis period of undergraduates!
For ordinary people, during the doctoral period, it is simply a luxury to easily handle their academic topics and produce results!
This is especially true for their engineering PhDs who specialize in plasma.
I don’t even have the opportunity to write a water thesis, and if you want to pass the defense, you really have to get some results!
Originally, many people already had a general idea of what should be done.
But the problem is… It’s at this most critical point in time.
The laboratory was actually sealed?
There is no laboratory, what does this allow them to take and solve problems?
“Students, I also know your concerns, but this laboratory, don’t talk about you… The teacher can’t actually enter now.
Professor Wang’s eyes showed a hint of helplessness, and he shook his head and said.
“Can’t even you get in?”
Everyone was slightly stunned, all a little disbelieving:
“But… Professor Wang, aren’t you just: Isn’t that the director of that plasma laser research institute? If you can’t even get in, who else can? ”
They were all a little dumbfounded.
Even the director can’t get in, who else can?
“The current situation, let me think about how to explain it to you…”
Professor Wang rubbed his temples helplessly, thinking in his mind how to explain to these students what was happening in the institute.
But after thinking about it, he found that even he didn’t know what was going on in the institute now!
In fact, this in itself is quite outrageous!
Originally, the entire plasma laser research institute was operating normally, but suddenly a paper order from above directly moved away many high-end instruments in the institute?
Just move the instrument away.
There was actually a group of people in the back, who moved directly into the research institute, and then closed the research institute!
Say what to do… Confidentiality level research, no one is allowed to enter!
Not even his director!
This is very depressing!
As the director of the entire Plasma Laser Research Institute, not only did he not even have the right to use it, but he didn’t even know what was going on!
In the face of students’ questions, Professor Wang really didn’t know how to explain.
“Professor Wang, you really can’t get in?”
Seeing Professor Wang’s embarrassed look, his students looked at each other, and their eyes also showed a look of doubt.
They could see that what their teacher had just said did not seem to be fake.
That’s hilarious!
Professor Wang is an expert in plasma lasers in China and has excellent technical business knowledge.
Because of this, while serving as a professor at the National People’s University, he also served as the director of a plasma laser research institute!
As a result, this institute was suddenly closed, not to mention these students, and even the director himself could not enter?
It’s also hilarious!
“Professor Wang, do you want to ask the above what is the situation?”
“It’s also too… Bizarre.
“Don’t give us a chance to complete the experiment, at least, we have to have a right to know!”
One student couldn’t help but say.
This kind of being kept in the dark is really a little too uncomfortable!
However, as soon as he said this, he was refuted by another student: “What do you think? If it is really a confidential project, then where will it be our turn to ask? ”
Can you use your brain?”
“I, I just don’t think it’s fair!”
The refuted classmate turned red and showed a look of embarrassment on his face. However, he didn’t say anything more, knowing that his words were inappropriate.
If the research content being carried out in the Plasma Laser Body Research Institute is really a so-called national confidential project, it is indeed not their turn for these students to come out and point fingers.
To put it bluntly, their doctoral dissertation topics are compared to real defense projects… That’s it.
“So be it.”
“I’ll try it and see if I can fight for it.”
Professor Wang thought for a while and said, ”
I also feel that this matter reveals something strange.”
“In this way, I’ll try again when the time comes, can I fight for it for you.”
“Long live the mentor!”
After leaving the office, Professor Wang hesitated again and again, but still made a phone call.
“Hey, Minister Sun.”
“Yes, it’s me.”
Although in name, he is only a professor at the National People’s University, but in the professional field he studies, he is a bull-level existence in the entire industry!
Many projects at hand are also directly related to the top of the state or military enterprises!
Therefore, his side can actually contact Minister Sun directly.
“Professor Wang?”
“You came here to Xingshi to ask about sin, right?”
Listening to Professor Wang’s voice in the microphone, a smile flashed in Minister Sun’s eyes, and he asked with a smile.
“Minister Sun, Xingshi must not be able to talk about sin!”
“But… If you want to give me an accurate word, not to let me know what is going on in the Plasma Aurora Research Institute, at least let me know when we can use the institute again, right?
“Besides, we don’t need much equipment, just a few electromagnetic sensors and plasma aggregators.”
“I have so many students with me, but they are all waiting to do projects.”
Professor Wang said with a look of grievance.
Sometimes that’s how it is for crying children to have milk.
“Lao Wang, I know the grievances in your heart.”
“But inside this plasma laser research institute, there is indeed a very important project going on.”
Minister Sun can also guess what Professor Wang thinks in his heart, after all, anyone who has experienced similar things will probably not feel good in their hearts!
He could only gently persuade:
“How long it will take for this project to be completely completed, I can’t give you an accurate answer.”
“I promise you, though.”
“Once the project is over, I will inform you immediately, and when the next funds are issued, your laser research institute will share more research funds as compensation for this occupation.”
“Lao Wang, what do you think?”
Hearing Minister Sun’s words, Director Wang on the other side of the microphone was still a little dissatisfied.
“Minister Sun, this is not a question of funding or not! It’s almost graduation season, and I have several older PhDs on my hands, waiting to graduate!
“Without the institute, their results really can’t be obtained!”
“…”
