Chapter 1014 Solar Flare

"Hi everyone, I am Yingshu, the person in charge of the communication engineering department of Kyushu Science and Technology. In fact, I am not suitable to explain our company's communication engineering technology to you today, because the successful development of this technology is inseparable from Li Cun, Wang You, The efforts of those in charge like Zhao Wei are also inseparable from the efforts of Zhan Kunhu, the head of the satellite R\u0026D and manufacturing department under the aerospace department of our company, and the engineers, scientists, mathematicians, and technical staff of the two major departments.

What I personally know is just a general overview. If I go deeper, I only have a little bit of expertise in data encryption transmission, analysis and optimization of satellite communication engineering. "

In his self-effacing, Yingshu did not mention his incomparable experience and treatment as a top student, let alone his family background.

It's just that the old foxes present have already automatically filtered out this kind of self-effacement. In their view, the person who can be entrusted by Gu Qing to the most important project of scientific research and technology cannot be an ordinary genius.

Ordinary geniuses are the targets of competition for companies like myself...

After introducing himself, Yingshu did not directly introduce the PPT pictures, but first said: "In recent years, technology companies such as mobile phone manufacturers and system R\u0026D companies have been launching satellite communication services for individuals. If this is technology decentralization, then It took decades for satellite communication services to be released to commercial and civilian use, which can already show how difficult this technology is from the side.

In the current mobile Internet world, the communication network speed of 4G/5G can already meet the daily Internet access needs of ordinary users, but now the mobile Internet market is approaching saturation, and the frequency of user replacement is reduced, and everyone is scrambling for the stock market.

5G has been available for several years, and no better application has been implemented until now. Now, the Starlink project of Tesla President Musk, or the 6G communication technology that is still being debated in the academic circles, can actually be regarded as a generalized technology. satellite communication technology. "

Under the unbelievable gazes of the high-level executives of technology companies, Yingshu shook his head modestly and said: "Of course, the satellite communication that our Kyushu Technology currently masters is not 6G communication technology, and it can even be said that it is worse than 5G in terms of use. , because the cost of our Kyushu satellite communication technology is still a bit high.

In fact, after the 01 satellite of our official Tiantong No. 1 project was launched into the sky, a certain letter company in Daxia released an Tianyi satellite phone. In addition to renting, there is an initial installation fee of 1,000 yuan, the minimum charge for making/receiving calls is 1.8 yuan/minute, and the highest is 66.8 yuan/minute, and the mobile phone data usage charge for this mobile phone is as high as 16 yuan/Mb.

If users do not use satellite communication functions frequently, the cost of operating and maintaining satellites will become very high.

And this dilemma may be rewritten in the two years of this year and next year. "

After Yingshu said this, he directly flipped the PPT on the main screen to the next page.

That's a scorching picture of the sun's surface.

We have had close exchanges with experts from the Space Environment Forecasting Center of the Daxia Academy of Sciences, and learned that the blue star is currently in the rising stage of solar activity, and the phenomenon of sunspots is almost increasing day by day. Recently, several large structures with complex structures have appeared on the sun Sunspot groups, resulting in M-class flares erupting almost every day, and occasionally X-class flares.

A sufficiently strong solar eruption will throw a large amount of energy and matter into the surrounding space. These energy and matter are usually expressed in the form of electromagnetic radiation, high-energy charged particle flow and plasma clouds, and their impact on blue stars is no less For certain conceptual weapons.

In the past two years, our sun has erupted more than once X2.2-level large flares. When a large flare erupted, our big summer happened to be on the sunny side, and only ten minutes after the eruption of the large flare, it sharply intensified When the electromagnetic radiation reaches our Daxia area, it causes a sudden disturbance of the ionosphere in the Daxia area, interferes with the propagation of wireless signals, and causes the attenuation of short-wave radio signals.

Internationally, X-ray flares are divided into five levels according to the magnitude of the peak flux of soft X-rays, namely A, B, C, M, and X, and the released energy increases by 10 times in turn.

Flares below C level are small flares, M level flares are medium flares, and X level flares are large flares. The X2.2 level means that the soft X-ray peak flux of the flare is 2.2×10-4 W/square meter, which can release a huge energy of 1025 joules in 1 second.

The energy released by that flare is roughly equivalent to the simultaneous explosion of billions of giant green bombs.

At present, our blue star is in the 25th round of sunspot activity cycle. It is estimated that by 2025, the sunspot activity will reach its peak. At that time, the sun that created us and nurtured us will burst out frequent and intense energy.

Just like the moon's influence on tides and creatures, the peak activity of sunspots will also affect every plant and tree on our blue star, and new drastic changes will occur.

When 3G, 4G, and 5G networks are subject to frequent disturbances and fluctuations, users often see news of natural disasters in the news, and even more people suffer from natural disasters, satellite communication will be the biggest outlet for communication engineering.

For military, commercial, and civilian use, satellite communication, which is comparable to the transmission capacity of 4G communication engineering, and Kyushu satellite communication technology, which can be upgraded to near the transmission capacity of 5G communication engineering in the future, will surely become an essential technical function of smartphones in the new century. "

He is obviously a man of science and engineering who has been obsessed with research and development all year round. He doesn't know what happened to him, but he will start selling anxiety, which makes many high-level people in technology companies twitch their eyelids.

Perhaps this is the relationship between trust and strength.

If it were an ordinary company to engage in this kind of publicity to attract investment, no one sitting here would be willing to invest money, and it is even very likely that the security guards will be asked to pull out this bewitching person.

But this time it is the content of the high-level project leader of Kyushu Technology.

Even Mr. Xia Weiren, who has seen many storms and waves, couldn't help frowning and thinking deeply.

It was Xiawei's long-term strategy to carry out commercial and civil communication technology around the Daxia Beidou Project. Although limited by geopolitical factors, this project can only be re-opened locally, but there will definitely be opportunities to expand its influence in the future regional.

Now Kyushu Science and Technology has also come to intervene, and it seems that it is not a temporary idea, but the technical achievements of many years of intensive cultivation, so it will be difficult.

Is it like the smartphone system in the past, following behind Kyushu Technology, allowing the opponent to resist pressure, and secretly developing its own Hongmeng?
