Chapter 1015 Solar Flare
"Hello everyone, I am Yingshu, the head of the communication engineering department of Jiuzhou Technology. In fact, I am not suitable to explain our company's communication engineering technology today, because the successful development of this technology is inseparable from the efforts of Li Cun, Wang You, Zhao Wei and other leaders, and also inseparable from the efforts of Zhan Kunhu, the head of the satellite research and development and manufacturing department under the aerospace department of our company, and the engineers, scientists, mathematicians, and technical staff of the two departments.
My personal understanding is just a general overview. If I go deeper, I am only a little good at data encryption transmission and analysis optimization of satellite communication engineering."
In his modesty, Yingshu did not mention his former glorious resume and academic treatment, nor did he mention his family background.
It's just that the old foxes present have automatically filtered out this kind of modesty. In their opinion, a person who can be entrusted with important tasks by Gu Qing in such a most important scientific research and technology project cannot be an ordinary genius.
Ordinary geniuses are the objects of competition among these companies...
After introducing himself, Yingshu did not directly introduce the PPT pictures, but first said: "In recent years, mobile phone manufacturers, system development companies and other technology companies have launched satellite communication services for individuals. If this is the decentralization of technology, then it took decades for satellite communication services to be decentralized to commercial and civilian use, which can show from the side how difficult this technology is.
In the current mobile Internet world, the communication speed of 4G/5G can already meet the daily Internet needs of ordinary users, and now the mobile Internet market is approaching saturation, the frequency of users changing phones has decreased, and everyone is competing for the existing market.
5G has been on the market for several years, and there is no better application until now. Now Tesla President Musk's Starlink plan, or the 6G communication technology that is still being debated in academia, can actually be regarded as satellite communication technology in a broad sense."
In the incredulous eyes of a group of technology company executives, Yingshu Shu shook his head modestly and said: "Of course, the satellite communication that Jiuzhou Technology currently has is not 6G communication technology. It can even be said that it is worse than 5G in terms of use, because the cost of our Jiuzhou satellite communication technology is still a bit high.
In fact, after the launch of the 01 satellite of our Daxia official Tiantong-1 project, a certain telecommunications company in Daxia released a Tianyi satellite phone. In addition to the call charges and monthly rent like ordinary mobile phones, this satellite phone also has an initial installation fee of 1,000 yuan. The minimum charge for making/receiving calls is 1.8 yuan/minute and the maximum is 66.8 yuan/minute. In addition, the mobile data usage fee of this phone is as high as 16 yuan/Mb.
If users do not use the satellite communication function frequently, the cost of operating and maintaining the satellite will become very high.
And this dilemma may be rewritten in the next two years this year and next year."
After saying this, Yingshu turned the PPT on the main screen to the next page.
That was a hot picture of the surface of the sun.
We have had close exchanges with experts from the Space Environment Forecast Center of Daxia Academy of Sciences and learned that the blue planet is currently in the rising stage of solar activity. The sunspot phenomenon is almost increasing day by day. Several large sunspot groups with complex structures have appeared on the sun recently, resulting in M-level flares almost every day, and occasionally X-level flares.
A sufficiently strong solar eruption will eject a large amount of energy and matter into the surrounding space. These energy and matter are usually manifested in the form of electromagnetic radiation, high-energy charged particle flow and plasma cloud, and their impact on the blue planet is no less than that of some conceptual weapons.
In the past two years, our sun has erupted more than once with X2.2-level large flares. When a large flare erupted, Daxia happened to be on the sunward side. Only ten minutes after the eruption of the large flare, the sharply enhanced electromagnetic radiation reached our Daxia area, causing sudden disturbance of the ionosphere in the Daxia area, interfering with the propagation of wireless signals, and causing the attenuation of short-wave radio signals.
Internationally, X-ray flares are divided into five levels according to the magnitude of the peak flow of soft X-rays, namely A, B, C, M and X, and the energy released increases by 10 times in turn.
Flares below C level are all small flares, M level flares are medium flares, and X level flares are large flares. X2.2 level means that the peak flux of soft X-rays of the flare is 2.2×10-4 watts/square meter, which can release a huge energy of 1025 joules in 1 second.
The energy released by that flare is about equivalent to billions of giant green bombs exploding at the same time.
Our blue planet is currently in the 25th round of sunspot activity cycle. It is expected 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 impact of the moon on tides and organisms, the peak activity of sunspots will also affect every plant and tree on our blue planet, and new upheavals will occur.
When 3G, 4G, and 5G networks will frequently suffer from harassment fluctuations, users will often see news about natural disasters in the news, and even when the number of people suffering from natural disasters increases, satellite communications will be the biggest outlet for communication engineering.
Military, commercial, and civilian use, satellite communications are comparable to the transmission capabilities of 4G communications engineering. In the future, they can be upgraded to the transmission capabilities close to 5G communications engineering. Kyushu satellite communications technology will surely become a necessary technical function for smartphones in the new century. "
He is a man of science and engineering who has been devoted to research and development for many years. I don’t know what happened to him. He actually started to sell anxiety, which made many senior executives of technology companies jump.
Perhaps this is the connection between trust and strength.
If an ordinary company came to do this kind of publicity to attract investment, no one present would be willing to invest money, and it is even very likely that the security would be directly asked to pull this person who spread rumors out.
But this time it was the content told by the senior project manager of Jiuzhou Technology.
Even Xia Weiren, who has seen many storms, couldn’t help but frown and think deeply.
It was originally planned to carry out commercial and civilian communication technology around the Daxia Beidou project. It was a long-term strategy of Xia Wei. Although it was limited by geopolitical factors, this project could only be started in the local area, but there would definitely be opportunities to expand the impact area in the future.
Now Jiuzhou Technology has also intervened, and it seems that it is not a temporary idea, but the landing of technical results of many years of deep cultivation. That would be difficult.
Is it like the smartphone system back then, following Jiuzhou Technology, letting the other party bear the pressure, and secretly developing Hongmeng?
