Chapter 953 Satellite (4K)
But just when Yingshu and others' eyes lit up, he changed his voice and said: "It's just that there are many projects being promoted internally within the company, so the computing resources are a little tight. Although These will be solved, but regarding the 6G project, I personally think your department can calm down again.
Based on the long-term progress of the company’s think tank team and your department, what is currently known is that the 6G communication network The theoretical download speed will reach 1TB per second
5G will be integrated with 6G and then upgraded to 6G. We have already done research and principles on regional satellite communication technology, so the company will start this year. The project is upgraded to the same level as the aerospace project.
Integrate satellite networks on the basis of 5G to achieve global coverage, treat 5G as global wifi, and then carry out major upgrades.
Although some people think that 6G is based on the terahertz frequency band, and some people think that 5G + AI2.0 is the 6G network, the unified understanding is that 6G is definitely a fusion of multiple networks - land, sky and even multiple levels. In the future, The joint networking of satellites and joint networking of land communications includes not only low-orbit satellites, but also high-orbit satellites, and even higher satellites.
As the basis for these, our network architecture and engineering formulas need to be solid and advanced enough to support the technologies that can be realized by this 6G network. "
Seeing that some of the senior executives of the 6G communication engineering department looked a bit off, Gu Qing paused, and then said seriously: "Although our officials and companies like Xia Wei and Xia Xing have mastered the 5G network communication engineering. There are many core patented technologies, but the United States has not given up.
Five years ago, the Berry Federal Communications Commission voted unanimously to open the terahertz wave frequency band, which ranges from 95GHz to 3THz, which is the frequency band that technical experts had predicted that 6G communication technology would enter.
This shows that the United States has completely given up competing with us on the 5G network and is instead focusing on the 6G network communication project. ”
This "outdated news" mentioned by Gu Qing once again made the senior executives of the 6G Communications g engineering department feel heavy pressure on their shoulders.
Because the company has not made any achievements in 4G and 5G, it once relied on Xia Wei's "help" on many projects, thus losing a lot of revenue from some projects.
And now, with 6G just around the corner and everyone running wildly, if something done by the United States is mentioned again in the past, it definitely means that the other party has made clear progress.
As the person in charge of the 6G communication engineering project, Yingshu is naturally no stranger to terahertz electromagnetic waves. Other engineers and mathematicians have also been exploring this electromagnetic wave.
1THz=1000GHz is in the transition area from macroscopic classical theory to microscopic quantum theory, and from electronics to photonics.
In terms of frequency, it is higher than microwaves and lower than infrared rays. The energy size is between electrons and photons.
The 5G frequency band has been expanded from 450MHz to 60GHz, and the download speed has reached second speed. And going further to above 95GHz, 6G entering the terahertz frequency band will undoubtedly bring about earth-shaking changes to the world.
The huge data brought by Internet devices and billions of sensors in all environments around the world cannot be realized without a good enough formula foundation and engineering structure.
And Gu Qing also made a big success for many mathematicians and engineers.
He said with a look of longing: "When our 6G communication technology can be implemented and popularized, then we can realize the democratization of many functions that can only be achieved based on 6G.
For example, in a real holographic call, a real 3D model is constructed to allow both parties to the call to exist in three dimensions. For example, full-sensory data transmission allows users around the world to not only hear and see, but also touch, smell, and experience.
In the field of phone communication, immersive shopping, tactility in virtual games, true intelligent autonomous driving and other technologies, the implementation of each technology will earn us immeasurable benefits.
Even if we do not develop these technologies, we can still charge considerable royalties, and these profits will be distributed in proportion to everyone who contributes to the 6G communication project.
I look forward to seeing how many tens of billions and hundreds of billions of people can emerge from Jiuzhou Technology. ”
Gulu.
I don't know who swallowed.
If another boss had drawn this kind of pie, no one here might have believed it, but if it was Gu Qing who said this, then the whole world, even Americans, would believe it...
Those " "Childish and superficial" undergraduates and graduate students entered Jiuzhou Science and Technology early and participated in many projects. Now many of them have entered the billion-dollar club.
Moreover, these people still have hundreds of millions in cash, not any other assets, and the profits of the projects they participate in will be disbursed in proportion every year.
If 6G could really be produced by myself and others, even if it was a one-ten-thousandth share of the revenue, it would be a somewhat breathtaking figure.
Mathematicians and engineers from the 6G communication engineering department of Jiuzhou Technology, Li Cun, Wang You, Zhao Wei, Ou Yansong and others have some ideas.
“Our company’s think tank team and the academicians and doctoral supervisors in the university alliance are all working hard on this project. Even the newly upgraded AI Xiezhi is also providing a lot of help for this project.
After these three earth-orbiting satellites are launched into space today, you will also begin to cooperate more closely with other departments. Deduction development work has many responsibilities, but time is limited.
Everyone, our journey is destined to not be smooth sailing, but if we start slacking off halfway through the journey, the end point will be far away. ”< br>
After completing the psychological construction of a group of senior executives, Gu Qingcai left the conference room.
After communicating with each other for a while, senior executives Ying Shu, Li Cun and others from Jiuzhou Technology's 6G Communications Engineering Department became calmer.
After they regained their fighting spirit, they got up and headed to the observation center of the rocket launch pad.
They need to communicate with the R&D and production department of this satellite. Although they have always maintained close communication, no amount of communication and attention will be troublesome for the networking of this regional satellite. .
In the midst of anxiety, the most fearful thing about winning numbers is that when the satellite is launched into orbit and the equipment begins to actually operate, if the data transmission and communication engineering protocols do not start operating according to the settings, it will be a disaster.
Although the satellite R&D and satellite manufacturing departments under the Jiuzhou Science and Technology Aerospace Department are very inconspicuous, occupying less than a few words in a novel, the department’s resources cannot be underestimated, because this department Most of the people there are researchers and engineers in the Titan department.
This is a professional matter. Do one thing and get two wages, why not do it?
The person in charge of Jiuzhou Science and Technology Satellite R&D and Manufacturing Department is named Zhan Kunhu. You will know the achievements of his ancestors when you see his surname.
If Jiuzhou Technology was not sincere enough, he might still be willing to work in a certain unit. "According to our forecast, the scale of the global aerospace industry will grow from two trillion summer dollars in 1016 to more than fifteen trillion summer dollars in 1050, with a compound annual growth rate of more than 6%.
A lot of this growth will come from low-orbit communication satellites
Dr. Ying, we all know the advantages of low-orbit satellites being close to the ground, short communication delay, high data transmission rate, and heavy in weight of mobile terminals.
And with the efforts of our company's semiconductor department, the communication satellites launched today all use carbon-based chips, so these advantages are further amplified, while the disadvantages are further reduced.
However, we have not obtained the agreement authorization. Although we can use these frequency bands at this stage, once they are made public in the future, we will inevitably be hunted by patent holders of these frequency bands. ”
Zhan Kunhu was worried about the future of this project. Why hasn’t Yingshu had a headache over this old and difficult problem?
But just after being given an injection of adrenaline by Gu Qing, he There is no need to frown at all at this moment of ambition
Therefore, in the face of Zhan Kunhu's thoughts, Yingshu replied with a heroic look: "At this stage, we are just doing experiments and exploration, and we don't need to go international. We just need to maintain cooperation with the aerospace department. In the future, we can Maintain technology on Earth and outer space, as well as on two transit rest stops Just support it. No matter how strict the laws on earth are, they can’t control our space field, right?
Otherwise, they can still shoot us down with satellite missiles.”
Did you win? As soon as he said these words, Zhan Kunhu immediately felt something was wrong.
In previous conversations, the other party was knowledgeable, down-to-earth and responsible, and spoke in a somewhat muffled voice, but today his thinking is lively and jumping like a young man's.
So he looked at the other party with a strange look.
However, Yingshu didn't notice his own changes. The entire senior staff of Jiuzhou Technology seemed to have similar changes after being in contact with Gu Qing for a long time.
Being more and more susceptible to the influence of one's own boss's words, whether it is understanding things or doing academic work, for some reasons, he will start to draw a clear line with his former employer.
Jiuzhou Technology has already passed the initial difficult time of accumulating capital, and now it has entered a period of rapid development. Why doesn't Gu Qing make "back-up preparations" for such rapid development?
It is no exaggeration to say that all the research and development results of Jiuzhou Technology are the seeds planted by Gu Qing, and these scientists, engineers, and even ordinary employees who "suddenly had inspiration" all worked for this Gardener, bee watering seeds.
Taoyao is a magical drink that can invigorate the spirit, improve physical fitness, and repair physical damage.
But no one knows that long-term drinking of Taoyao and contact with Gu Qing will unknowingly regard Gu Qing as a being similar to the patriarch.
The soul can affect the body, and the body can naturally affect the soul.
It is precisely because of this that Gu Qing will become more and more "generous" in delegating power, allowing his company's engineers and scientists to come up with the black technology developed by the team as long as they feel the time is right.
Gu is not afraid of investigations by interested people at all. After all, the R&D teams of these black technologies all have names.
……
The artificial satellite device, as its name suggests, has a variety of shapes, such as sphere, spherical polyhedron, cylinder, polyhedron, etc.
At first, artificial satellites were basically spherical or spherical polyhedral. The world's first artificial satellite, Sputnik 1, was spherical, and Daxia's first artificial satellite, Dongfanghong, was spherical and polyhedral.
This is mainly due to the limited size of the payload and load bay of early launch vehicles.
For the same volume, the spherical or spherical polyhedral shape has the smallest surface area, which can effectively reduce the size and weight, thus reducing the burden on the launch vehicle.
Subsequently, in order to install enough solar panels to "charge" satellites, cylindrical or prism-shaped satellites gradually became the mainstream.
With the advancement of science and technology and the increasing number of tasks that satellites need to complete, satellites carry more and more equipment, and their weight increases. Naturally, the energy required must also increase. Therefore, current satellites directly use independent solar panels for power supply. came out and became a separate component, forming a modern satellite that orbits with wings.
Jiuzhou Technology's low-orbit communication satellite is installed in the "head device" of the rocket. Its mechanical structure is not much different from that of ordinary low-orbit satellites, but its appearance is not as eye-catching as those of ordinary low-orbit satellites. Cables and excess equipment that feel “techy”.
The attitude control system used is a traditional three-axis stable attitude control technology, which is an attitude control technology that allows the three mutually perpendicular axes of the spacecraft to have the expected direction in space relative to a certain reference system, so There are no strict requirements for satellite appearance.
But only the designers, developers and manufacturers of this satellite know how difficult the integration technology is hidden under the humble appearance of this satellite.
Although it flies out of the ground, it still has to obey the universal gravitation. Therefore, compared with high-orbiting satellites, the lower the altitude of the satellite, the greater the gravity.
Five years ago, Daxia’s first low-orbit broadband 5G communication satellite with a communication capability of 10Gbps, the Galaxy Space First Satellite, was launched.
Five years later, an unknown launch mission, the world’s first low-orbit communication satellite for 6G small area experiments, will be launched.
The former brought all professional equipment and instruments, while the latter, in addition to related professional equipment and instruments, also brought three medium-sized robotic arms, as well as a special launch device and photography device .
Elon Musk’s “Starlink Project” The “12,000 Satellite Constellation” plan submitted by SpaceX states that the satellites of the Starlink Project are distributed at 340 kilometers, 550 kilometers and 1,150 kilometers. A low orbit.
The Daxia Space Station has experienced more than one Starlink satellite "out of control" in recent years, which not only affected the stable operation of the space station, but also interfered with the conduct of some experiments, forcing Daxia officials to come out and ask SpaceX to admit its mistake and Corrected the mistake, but the other party just looked like he was a dead pig and was not afraid of boiling water, which made some senior officials of the Daxia Aerospace Department so angry that they were speechless.
Therefore, Zhan Kunhu, the head of Jiuzhou Science and Technology Satellite R&D and Manufacturing Department, led department engineers and the company’s think tank team during a meeting and consultation, and they unanimously agreed that they should install “defensive equipment” that can counterattack on their own satellites.
PS: Thanks for the recommendation votes and monthly votes.
Good night, everyone.
Goodbye, November.
