Is it difficult to produce a satellite?

In terms of production technology, it's not difficult.

When the domestic satellite industry was not yet in commercial operation, many domestic universities and colleges were making their own satellites for experiments.

As the commercialization of satellites becomes more and more open, master students and even graduate students in the satellite major now have to build a satellite and successfully launch it into space.

It can be said that it is not difficult to simply build a satellite to fly into space.

but!

There are certain technical difficulties in producing a commercial satellite that has good performance and can be stable in orbit for a long time and operate normally.

As we all know, the environment in space is a hundred times worse than on earth.

First of all, the temperature difference in space is extremely large. The temperature of the side facing the sun can reach 120℃~130℃, while the temperature of the side facing away from the sun can be as low as 150℃~170℃. The huge temperature difference is very difficult for the normal operation of various instruments of the satellite.

A huge test.

In addition, satellites in space will also face the threat of vacuum environment and the impact of various space particles, space radiation, and even space particles!

It can be said that these problems encountered in outer space must be taken into consideration at the beginning of satellite design!

In the face of space radiation and particles, what kind of material will be used for the satellite skin, what kind of material coating will be applied to the important parts of the satellite, and what kind of process will be used to package the internal parts, all must be considered in detail!

and!

In addition to these stability requirements, commercial satellites also have another important indicator, which is the payload!

To put it simply, it is the miniaturization of satellites.

Many years ago, when the first computer appeared, it was as big as half a room. With the advancement of technology, computers have gradually evolved from "big guys" to now integrated into thin laptops.

It can be said that the development trend of commercial satellites is no exception!

Nowadays, with the development of electronic equipment and the application of highly integrated technology, commercial satellites are increasingly pursuing miniaturization and lightweight. The lighter and smaller they are, the more they pursue better performance!

It is no exaggeration to say that the future satellites must be dominated by miniaturized satellites. Whoever masters the technology of satellite miniaturization will master the absolute core technology in the field of satellite design!

…

At this moment, the headquarters of "Happy Planet" in Chengdu is brightly lit.

All technicians and employees in the entire company were mobilized urgently, and everyone's face was filled with excitement.

With Hu Laichao's ability, Zhang Xiaoou quickly convened a meeting with all employees as soon as he returned to the company.

The 1 million advanced by Phoenix Group has been received, and Zhang Xiaoou was unambiguous. Each of the more than 20 employees directly paid 3,000 yuan in overtime pay in advance. With the financial stimulation, the entire production team started working like a chicken blood!

In Zhang Xiaoou's office.

Zhou Ping, who is also one of the founders of "Happy Planet", just hung up the phone, then looked at Zhang Xiaoou and said:

"Xiaoou, I have contacted the manufacturer of the panchromatic multispectral camera. Currently, only the Hangzhou Caipu camera meets the Phoenix parameter requirements, but the other party's price is much more expensive than what we use!"

"Also, we have never tried this 'panchromatic multispectral camera' before. Are you sure there will be no problems with this camera on a satellite?"

Zhang Xiaoou couldn't help but pout. After signing the contract with Hu Lai, he immediately started a serious discussion with Hu Lai.

Most of the information provided by Phoenix Group only indicates the relevant parameters of the instrument, and there is no detailed explanation of the manufacturer and other information.

Just when he had some objections to various data, Mr. Hu directly said that it would be enough to purchase the instrument according to the parameters in the data!

Thinking of this, Zhang Xiaoou shook his head and said:

"Let's not worry about the price. I have already informed Mr. Hu as to whether it can be used."

"If they insist on this, just follow the performance parameters they gave us and we will be responsible for the procurement!"

"Okay!"

Zhou Ping nodded heavily, and after a moment couldn't help but ask:

"Xiaoou, you and I are both born in technology. Did you read carefully the satellite design provided by Phoenix?"

Having said this, Zhang Xiaoou was stunned for a moment, obviously guessing what Zhou Ping wanted to say.

"I saw it, I saw it right away!"

"Brother Ping, seriously, do you feel hopeless?!"

As he spoke, he paused and said with a wry smile:

"Before, we thought Phoenix Group was a large enterprise with strong technological research and development capabilities."

"I have finally seen the technological strength of the Phoenix Group now. I have never heard that they are involved in the satellite industry before, but the design accomplishments of this design drawing alone are far ahead of our 'Happy Planet' satellite design concept."

"Their flat design of the overall structure, electric propulsion technology and internal structure distribution of the satellite shocked me so much. They simply made full use of all the space inside the satellite."

Zhang Zhouping on the side couldn't help but shook his head and sighed:

"yes!"

"It is not difficult to make satellites miniaturized. What is rare is that they not only miniaturized them, but also..."

"Have you seen their design performance? Their design performance has far exceeded the performance parameters that ordinary small remote sensing satellites can achieve..."

"The satellite revisit period alone is much shorter than that of ordinary small satellites. This is truly small and good!"

The two of them discussed the Phoenix Group's processing drawings with emotion, feeling a little envious and a little jealous...

At this moment, the phone on Zhang Xiaoou's desk suddenly rang.

"Hello... Mr. Li, hello!"

"Hey, yes, we have a launch mission in about half a month. Does your rocket still have a payload? What orbit is it?"

…

The Phoenix Group's satellite program is in full swing. At the same time, on the other side of the ocean.

In a luxurious villa, Cook personally accepted the invitation from Director Miller of the Federal Security Service of the United States and had a happy gathering.

Cook breathed a rare sigh of relief. Google has agreed to ban the Phoenix Group from providing overseas GMS services.

Moreover, with the assistance of the Federal Security Service, neither Google Maps nor domestic satellite map providers, nor EU map providers are allowed to provide electronic map data to the Phoenix Group.

even.

According to the latest news, Phoenix Group even wants to rent a SPOT-7 satellite owned by the French Space Agency as their data source!

It can be seen that the Phoenix Group has reached a dead end!

"Director Miller, thanks to your assistance this time, it will not be easy for the Phoenix Group to publish electronic maps overseas in the short term!"

Cook picked up the red wine glass and gestured slightly.

"Mr. Cook, you are too kind!"

"Thankfully it was your idea. The superiors quickly adopted it after I proposed it. This is also a situation we are happy to see!"

As he spoke, Miller snorted coldly:

"They ignored our ban this time and forcibly sold a large number of chips to the bears. This is their price."

"They are still dreaming of launching mobile phones into overseas markets, which is simply ridiculous!"

"By the way...Mr. Cook, your latest Hongguo 14 has been sold globally. How is your sales in Yanguo District?"

"Do Phoenix Group's mobile phones have any impact on you?"

Cook gently shook the red wine glass with a faint smile on his face:

"It did have some impact when their mobile phones were first launched, but for us, it is completely acceptable."

"Our sales volume of Hongguo 14 is slightly lower than the expected sales, but it is still higher than the sales volume of Hongguo 13."

"Director Miller, you have to know that our brand has been operating in Yanguo for so many years, and our influence has been deeply rooted..."

"Furthermore, we will release the facelift of Hongguo 14 at the press conference next spring. Once released, our sales should continue to hit new highs, don't worry!"

Miller smiled when he heard this and raised the red wine glass in his hand:

"Then I wish Mr. Cook a great success in selling the new phone!"

"cheers!"

Miller and Cook briefly exchanged a few words, and their eyes fell on Qualcomm CEO Anmon beside the wine table.

He took another glass of red wine on the table and walked over slowly...

"Anmeng, how is the recent chip business..."

"Let me tell you something quietly, Congress has passed a new resolution, and it is very likely that we will build a new chip factory..."

…

Just as we were celebrating across the sea, the satellite production area of ​​"Happy Planet" was in full swing.

Seven days later.

The "Happy Planet" assembly plant finally completed the last step of production!

All parts have been assembled and all tests have passed in one go!
