Chapter 864 Believe Me, Our Satellite Is for Civilian Use!

Naturally, Chang Haonan did not need to write the patent himself.

Anyway, he had already sorted out the core calculation process before.

As for other parts that need to be inked, most of them are clichés and can be left to the students who are new to the research group to complete.

Wang Jie, who has not yet left for Shanghai, is very suitable.

After all, writing patents is a specialty of the postgraduate stage and must be tasted.

As for Chang Haonan himself...

After deploying the mission, they set off for the Science and Technology Commission.

Since he promised Zhuang Bingchang to fight for a place for his... seed, he would definitely not break his promise.

Before setting off, Chang Haonan made a special phone call to confirm whether Ding Gaoheng was in the office——

Although he still had the authority to scan his face to enter, it had been several months since he had been to the Commission of Science, Technology and Industry for National Defense.

The last time I met Ding Gaoheng, he was invited to his home for dinner just after he sent out the paper proving the Poincaré conjecture.

Coming here this time, I even felt a little like revisiting my old place.

"Director Ding."

Chang Haonan came to the door of Ding Gaoheng's office, habitually preparing to knock on the open door and then walk in directly.

But as soon as he finished speaking and before he could raise his hand, he saw another person sitting in the room.

So, he still stopped.

When outsiders are around, you still have to behave formally.

Ding Gaoheng, who was talking to the man on the sofa, heard a knock on the door and turned around to see Chang Haonan standing at the door.

"Xiao Chang, come in and sit down."

When the other person heard Ding Gaoheng calling Chang Haonan, he immediately looked back.

They are still acquaintances.

"Director Luan?"

There was a moment of surprise in Chang Haonan's eyes.

But then he walked forward and shook hands with the other party:

"haven't seen you for a long time."

After saying that, he sat on another sofa next to him.

Luan Wenjie, Director of China National Space Administration.

This is indeed such a coincidence——

Although Chang Haonan called Ding Gaoheng just now, he did not explain the specific purpose of his visit.

Nominally speaking, the overall commander of the manned space project is the director of the Commission of Science, Technology and Industry for National Defense, namely Ding Gaoheng.

But this is mainly to facilitate the coordination of the power of the entire military industry system, and the nominal component is relatively large.

Therefore, in order to obtain a breeding opportunity for Zhuang Bingchang, Luan Wenjie would have to go to Luan Wenjie in the end.

As a result, the rightful owner happened to be there.

However, Chang Haonan did not speak immediately after he sat down.

We are all colleagues under the same system, and now we are not competing for houses or land, so we still have to talk about first come, first served.

However, although Chang Haonan did not interrupt the topic, Luan Wenjie took the initiative to look at him.

"Mr. Chang, Director Ding and I just mentioned you."

"oh?"

Chang Haonan, who was originally going to be in a daze to recuperate for a while, became interested.

You can't predict the situation between two people facing each other, right?

"Mr. Chang, you should know that our country has launched a total of three resource series remote sensing satellites independently and in cooperation with Brazil."

Luan Wenjie did not use a questioning tone, so Chang Haonan just nodded slightly.

Of course he knew this. After all, the satellite image that led to a series of topics and projects came from the Ziyu-201 star.

The former immediately continued:

"In the past few years, especially in the six months since the launch of the two Ziyu-2 satellites, space-based remote sensing has helped us solve many problems that were not easy to overcome in the past. Of course, we also borrowed a lot of light from Mr. Chang."

Borrowing Chang Haonan's light, naturally refers to the high-dimensional data dimensionality reduction algorithm he developed.

However, Chang Haonan himself was a little confused.

"Wait a minute, Director Luan."

He raised his hand to interrupt the other party:

"I have just begun to study the data obtained through data dimensionality reduction. Can this all benefit from my light?"

Chang Haonan has indeed relied on that algorithm to process different data several times, but the further results, whether it is the desert soilization he directed, or the geological analysis of permafrost and loess plateau that were previously handed over to other systems for research, are all Haven't taken it out yet.

How come you have “solved a lot of problems”?

I haven't exerted my strength yet?

But the way Chang Haonan looked at Luan Wenjie, it was obvious that he wasn't joking.

The interrupted Luan Wenjie and Ding Gaoheng looked at each other and explained with a smile:

"The data that has been reduced from too high a dimension still needs to be analyzed by Mr. Chang. However, after some relatively low-dimensional data has been reduced in dimension, we rely on the old method of increasing the sampling density and comparing it with known geographical information. , we can still dig out a lot of useful content.”

"For example, in July this year, we relied on these data to predict in advance a large-scale flash flood and debris flow in Ziyang County, Qin Province, and relocated people in 12 towns in advance. At least hundreds of casualties were avoided..."

Chang Haonan suddenly realized.

High-dimensional data is just a general term.

As Luan Wenjie said, it can still be divided into three, six or nine grades internally.

After dimensionality reduction, the forms of low-dimensional data are also different.

The only thing in common is that because they have become two/three-dimensional data, they can all be directly recognized by human perception.

Of course, just because 2D and 3D data can be read does not mean that it can be easily understood.

That’s why the data verification mentioned before is needed.

Because Chang Haonan is the developer of the algorithm, and he is also using cheats, his focus is naturally on data with higher original dimensions.

The amount of information hidden behind these data is greater, but correspondingly, it is more difficult to analyze.

But the route chosen by the Space Agency is normal to start with the easy and then the difficult.

So it is normal to be able to produce some results quickly.

In particular, the risk of geological disasters such as flash floods has obvious characteristics.

If it is an earthquake, it may be more troublesome.

At least the algorithm he has developed at present cannot handle it.

And Chang Haonan is naturally happy to see this.

After all, the route he set for himself when he was just reborn was not just a Doraemon who took out finished products, but to drive the development of related industries in China.

In the fields of aviation and machinery, he has achieved this goal.

And in the field of aerospace, it is at least a good start now.

While Chang Haonan was thinking secretly, Luan Wenjie took a sip of the tea on the table, and then returned to the previous topic:

"In short, through the application during this period, the superior unit has also intuitively realized the role and urgency of building a space-based remote sensing system, so it has approved a new sum of funds for us."

"Want to launch other remote sensing satellites?"

Chang Haonan now understood what the other party meant.

"Yes, but this time it is not a resource series."

Luan Wenjie replied:

"According to the original plan, we will launch my country's first marine resource satellite, Ocean No. 1A, between 2002 and 2003 to provide the Ministry of Land and Resources and the State Oceanic Administration with services such as marine biological resource development, marine pollution monitoring and marine scientific research."

"But now that we have this fund, we are ready to speed up the progress and strive to advance the launch mission to the first half of next year, and no later than the third quarter of next year."

"Then...what do you need me to do?"

Chang Haonan asked directly.

After hearing this, Luan Wenjie stopped talking about other things:

"The current resource series satellites use the onboard data system to transmit the original data, and then our ground station processes it to get the results. The advantage of this is that the requirements for the satellite are relatively low, but data can only be exchanged when the satellite passes overhead, and the timeliness is very poor."

"Of course, the resource series satellites mainly serve within our territory, which is not a big problem, but the ocean series satellites are mainly aimed at the Pacific region. If we use the old method again, it may not meet the requirements."

"So, we hope to hand over at least part of the data processing process to the onboard computer, which can greatly alleviate the transmission pressure..."

Hearing the other party's statement, Chang Haonan immediately curled his lips:

"Director Luan, the development of marine biological resources, marine pollution monitoring, marine scientific research... It seems that timeliness is not very important, right?"

He thought to himself that if the Ocean No. 1 only had this function, he would dare to eat the satellite.

Sure enough, after hearing his question, Ding Gaoheng, who had been sitting behind his desk without speaking, smiled and said to Luan Wenjie:

"I said you couldn't fool him..."

Then, he looked at Chang Haonan and explained:

"In recent years, we have developed an active radar system for large and medium-sized surface targets based on the technology of the Soviet Union's 'Legend' ocean surveillance system. In addition to the tasks that Comrade Wenjie just mentioned, Ocean No. 1 is also responsible for the performance test of this radar."

Chang Haonan's eyes widened slightly.

He had just guessed that this satellite must have military uses, otherwise there would be no need to pursue front-end data processing and timeliness.

But it was still completely unexpected to play such a big game:

"I remember that the Legend system needs to be powered by a satellite-borne nuclear battery. Our Ocean No. 1..."

"That definitely doesn't exist."

Luan Wenjie shook his head:

"The safety of nuclear batteries is too scary. Fortunately, our radar equipment consumes relatively little power, and a data link system for direct communication between satellites and fleets has been cancelled, so the solar panels are enough to serve..."

"So that's how it is..."

Chang Haonan has not completely recovered from the shock just now-

The "Legend" ocean surveillance system is the core of the Red Navy's anti-aircraft carrier system in the 1980s, including active US-A and passive US-P. It can locate the target individually based on the baseline interferometric phase comparison method, or it can be combined with two satellites for active and passive composite positioning.

Although the positioning accuracy itself is relatively average, only hundreds of meters or even kilometers under different conditions, anti-ship missiles with active radar seekers do not require particularly accurate target information.

It seems that in recent years, China has exchanged a lot of things from the north that were not obtained in the previous life.

If the ocean surveillance system can be built more than a decade in advance, it will definitely be a huge threat to the US military, which relies heavily on the naval fleet for physical deterrence.

Combined with the anti-ship ballistic missiles he had considered before...

Wouldn't this be a trump card weapon?
