Chapter 15 SWOT Analysis
Seeing that Wang Yinan was eating happily, he suddenly put down his chopsticks, with a loveless expression, Chief Yang wondered,
"Hey, what's wrong, what bad things have you eaten?" ,
"It's nothing, hey Lao Yang, do you know anything about transponders on satellites?" , Wang Yinan asked,
"I really don't understand this, but the airborne communication equipment has been used a lot, and the principle is similar, isn't it just that the power on the satellite is larger, and the capacity is larger."
"Nonsense, how can it be as easy as you say", Wang Yinan is happy, but this is a line of thought, you can't hang yourself on a tree, you have to find another tree, even if the satellite transponder is only provided by Dongfanghong Co., Ltd., there are always other signal transceiver equipment manufacturers, it's a big deal to use the transceiver antenna plus the core router to copy a transponder.
It seems that the Hughes company of the rice country is specialized in this, and the Hughes company also asked Huaguo to launch its own communication satellite at that time, can you buy a transponder from the Hughes company, this kind of thing is not easy to buy at the satellite level, what we need is the ground level, and the distance is almost unobstructed for hundreds of kilometers.
Wang Yinan called Zhang Qi and told him to inquire through foreign connections, and the transponder at this distance should not fall within the scope of the embargo of the bullshit Wassenaar Agreement.
Of course, far water can't quench the thirst of the near, and Wang Yinan didn't have much hope, so it could only be used as a backup measure as a last resort.
I can only hope that the comrades of Dongfanghong Company can be like their name, full of revolutionary romanticism, and not so ruthless to their comrades, Wang Yinan temporarily put his mind at ease, boarded the flight back to the imperial capital, and began to prepare to advance the stratoprowler plan.
Although he had never been in a rice or goose factory, Wang Yinan felt that his PPT skills were also first-class, and it was time to go back to retreat for a few days to prepare the PPT for the report.
Now the matter between him and Zhou Hui is already known to passers-by, but the strange thing is that all public opinion unanimously thinks that he was deceived by Zhou Hui's inexplicable tricks, and all entertainment reporters are asking the truth, just look at these online news headlines.
"How the new Abel Prize winner fell into the clutches of an actress, we will unravel the mystery for you",
"The earth-shattering conspiracy behind the love of the century",
"Is it love or adultery, who can see the bitterness hidden in Professor Wang Yinan's smile",
These reports made Zhou Hui angry, why am I a fox spirit, you Wang Yinan are like a victim, but there is no way, public opinion is still quite protective of a new giant panda like Wang Yinan, in order to attract attention, if there must be a villain, readers definitely don't want to see the villain Wang Yinan, so Zhou Hui can only carry this pot.
Wang Yinan spent several days for his stratoprowler plan and carefully prepared a beautifully made PPT.
The background is the silhouette of the 116 Wind Shadow stealth drone, which looks quite tall.
First of all, Wang Yinan listed several ways to build communication networks, the most common is the submarine fiber optic cable plus the backbone fiber optic cable across the land of China plus I-FI, 3G or 4G networks around the country, plus ADSL and the latest home optical fiber, this is the most flexible and adaptable way, but it takes a long time to build, and the investment is huge.
There is also the way of geosynchronous orbit communication satellite networking, which only needs to launch three to four satellites to form a global communication network, which is absolutely the fastest in terms of networking speed, but the problem is also obvious, the delay is significant, and the capacity is limited, and the meteorological conditions also have an impact on communication.
The third is the low-orbit communication satellite networking method represented by the Iridium program, for example, Iridium, which operates in a polar orbit at an altitude of 780 kilometers, with 6-7 orbits, and 11 satellites in each orbit can cover the whole world.
The fourth is the cellular drone scheme proposed by Wang Yinan, and of course, the balloon scheme that Mi Ge is working on.
Wang Yinan drew a table that listed the SOT analysis of all options, that is, listed the S (Strengths), (eaknesses), O (Opportunities) and T (Threats) of each option.
After comparing the advantages and disadvantages, Wang Yinan finally concluded that within the scope of China, considering various circumstances, from the perspective of performance indicators, construction costs, and construction cycles, stratospheric prowlers have huge advantages.
Next, Wang Yinan elaborated on the main technical scheme of the stratotropic prowler,
Using a UAV with certain stealth characteristics as a carrier of a transponder, the UAV does fixed-point cruise flight at an altitude of 20,000 to 30,000 meters.
The UAV adopts a wing body with a high lift coefficient and a pneumatic shape, with a composite fuselage, and the weight of the whole aircraft is very light.
Using large-capacity lithium batteries and solar panels as the source of electric energy, using solar drive motors to charge lithium batteries at the same time during the day, and using lithium batteries to power the motors at night, the continuous flight time can reach the charging and discharging limit time of lithium batteries for the longest time.
Using a superconducting electric motor to drive a large-diameter propeller as the propulsion equipment of the drone,
The various technologies used above, except for the superconducting motor that needs to be re-developed, are quite mature technologies, and although the superconducting motor is re-developed, as long as the permanent magnet in the high-performance permanent magnet motor is simply replaced by a superconducting coil, the performance can be greatly improved, and further improved versions can be continuously improved in the plan.
Using a regular hexagonal cellular network configuration, only 100 UAVs are needed to cover the entire country, including all sea areas.
The capacity of the network channel is only limited by the technology of the transponder, and with the current technology, there is no problem at all to reach more than one T of traffic.
The delay can be basically close to the physical limit between two points, of course, because it is transmitted through cellular, rather than point-to-point straight transmission, and the delay is about 10% higher than that of radio communication between two points.
In the end, Wang Yinan estimated the cost and construction time, the cost Wang Yinan first empty transponder, this thing made the above headache, he decided not to inquire about it, this kind of thankless thing, or do less.
This kind of project is basically a fishing project routine, come up and quote a low price to make people happy, and then wait for the project to be halfway through, there is no money, what do you say, the project is stopped? That's obviously impossible, so I had to continue to invest more.
The most typical example of fishing engineering is Ah San, that year Mao Xiong said, "Ah San, I heard that your old aircraft carrier is going to be retired, Mi has an aircraft carrier, it just so happens that I have a Gore that I don't need at home, and I will send you for free", Ah San listened to it for free, then of course it was good, "OK, okay", and I was busy agreeing,
"But this boat has a little problem, it can't be driven, you always have to pay for the repairs", Mao Xiong said, "Of course, it's a little meaning", Ah San was very refreshing,
"You have to buy some carrier-based aircraft, and there are boiler upgrades, this is a brand new product, there are no 400 million US dollars, you are embarrassed to take it"...
In the end, Ah San spent 2.8 billion US dollars to finally drive the aircraft carrier home.
Wang Yinan estimated the price of 4 million soft girl coins per drone, and the total project investment was about 500 million soft girl coins.
And the time spent on the project, if there are no major accidents, in a year, half of the drones deployed to reach the network is basically usable, it should still be quite sure.
With the freshly baked plan, Wang Yinan dialed Qian Zhonghua's phone, "How is your grandfather's health in the past two days, do you have time to listen to my report", Wang Yinan asked,
"Hurry up, the old man is still asking this morning, I'll learn from you", Qian Zhonghua said,
"Wang Yinan, this stinky boy, didn't he say last time that there was a way to solve our big problem, why hasn't there been news for so long, he used to do everything very quickly",
"Is it that after staying with a female star for a long time, his legs are weak, and you can tell him when you have time, the color is a bone scraper."
Wang Yinan's sweat immediately fell, "Thank you for your concern, the old man",
"But the conscience of heaven and earth, I didn't delay for a minute, and I implemented the technical plan everywhere, until it was almost foolproof, and I was ready to report to him."
In the evening, Wang Yinan drove to Qian's hometown, this time he was not embarrassed to take his sister with him, Qian Lao and Deng Lao were already waiting for him in the yard, of course, there was also Colonel Li of the Science and Technology Commission, Wang Yinan immediately felt that he had to look at this ordinary colonel differently, and provide consulting services anytime and anywhere, this is the exclusive think tank of the elderly.
Wang Yinan didn't talk much nonsense, turned on the large-screen LCD TV under the tree, and switched to the mobile phone synchronization mode familiarly, Wang Yinan began to explain his stratoproper plan to the three of them, and of course Qian Zhonghua, who played soy sauce.
As Wang Yinan calmly narrated, the two old men, as well as Colonel Li's mouth, opened wider and wider, and a few meaningless words popped out of Colonel Li's mouth from time to time, Wang Yinan sounded like he was scolding, Qian Zhonghua and Wang Yinan had been messing around for a long time, and they already had enough immunity to monsters, so they looked at the other three with disdain,
"Look at your little bit of interest, seeing a youkai like this, if you see a youkai traveling together, don't be scared and faint."
When Wang Yinan talked about the final performance data, the old men were not calm at all, the capacity was okay, the capacity of satellite communication was also enough, the delay data was too scary, "How many milliseconds, don't follow me to the physical limit or something, I don't understand, you just tell me how many hao seconds it takes from the imperial capital to the Zhongsha Islands, or how many thousandths of a second", Old Man Deng began to freak out,
Senior Colonel Li was really embarrassed, "The physical limit is how fast the light can go, let me help you calculate, the straight-line distance from the imperial capital to the Zhongsha Islands is about 3,000 kilometers, then Wang Yinan's delay should be able to achieve 11 milliseconds, that is, about one hundredth of a second."
When this intuitive data came out, Old Man Qian grabbed Wang Yinan's hand, "You didn't brag, you can't brag about this kind of thing, you have to lose your head",
Wang Yinan shook his head, "Where do I dare to brag, but Colonel Li has a little problem, the honeycomb path is still a little longer than a straight line, conservative calculation, 12 milliseconds",
What is called loading X, this is it.
It's like people complimenting you, "Oh, the author is so rich, and you have 400 million soft sister coins in your family",
You said very modestly, "Nonsense, how can there be so many, I read it yesterday, and it's only 390 million."
