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 currently being promoted within the company, so the computing resources are a bit tight. Although these will be solved, as for the 6G project, I Personally, I think your department can calm down again.

Based on the years of advancement by the company’s think tank team and your department, what is currently known is that the theoretical download speed of the 6G communication network will reach 1TB per second.

We have already completed the research and principles of regional satellite communication technology on the integration of 5G and 6G, and then upgraded to 6G, so the company will upgrade this project to the same level as the aerospace project starting this year.

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 + AI 2.0 is the 6G network, the unified understanding is that 6G is definitely a fusion of multiple networks - land, sky and even multiple layers. In the future, satellites The joint networking and land communication joint networking include 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 little strange, Gu Qing paused, and then said earnestly: "Although our officials and companies like Xia Wei and Xia Xing have mastered many core patented technologies of 5G network communication engineering, the United States But he didn't admit defeat.

Five years ago, the Berry FCC voted unanimously to open the terahertz wave frequency band, which ranges from 95GHz to 3THz, which is the frequency band that technology 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This "outdated news" mentioned by Gu Qing once again made the senior executives of the 6G Communications g engineering department feel heavy pressure on their shoulders.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.

But now, with 6G just around the corner and everyone running wildly, if something done by the United States is mentioned again, it definitely means that the other side 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, which 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 download speeds have reached second speeds. Going further than 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 hundreds of millions 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 communication, immersive shopping, tactility in virtual games, truly 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 usage fees, 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 made this kind of pie, no one might believe it, but if Gu Qing said this, the whole world, even Americans, would believe it...

Those "naive 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 other assets, and the profits of the projects they participate in will be disbursed in proportion every year.

If 6G can really be developed by himself and others, even if it is a one-ten-thousandth revenue share, it will be a somewhat breathless 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, and even the newly upgraded AI Xie Zhi is also providing a lot of help for this project.

After these three earth-orbiting satellites are launched into space today, you will also start to carry out closer joint deduction and development work with other departments. There are many responsibilities, but time is limited.

Everyone, our journey is destined to be bumpy, but if we start to slack off halfway through the journey, the destination will be far away. "

After doing psychological preparation for a group of senior executives, Gu Qing left the meeting room.

After communicating with each other for a while, Ying Shu, Li Cun and other senior executives of Jiuzhou Technology's 6G Communication Engineering Department calmed down a little.

After they regained their spirits, they got up and went to the observation center of the rocket launch pad.

They have to communicate with the R&D and production departments of this satellite. Although both parties have always maintained close communication, no matter how much communication and attention they pay to the networking of regional satellites, it is not a problem.

In trepidation, Ying Shu is most afraid that when the satellite is launched into orbit and the equipment starts to really run, the data transmission and communication engineering protocols will not work. If it starts to operate according to the setting, it will be a disaster.

Although the satellite R&D and satellite manufacturing departments under the aerospace department of Jiuzhou Technology are inconspicuous and only occupy a few words in a novel, the resources of the department cannot be underestimated, because most of the people in this department are researchers and engineers of the Titan Star Department.

It is a matter within the profession. Why not do one thing and get two salaries?

The head of the satellite R&D and manufacturing department of Jiuzhou Technology is named Zhan Kunhu. You can tell the merits of his ancestors by his surname.

If Jiuzhou Technology is 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 2 trillion Xia yuan in 1016 to more than 15 trillion Xia yuan in 1050, with an annual compound growth rate of more than 6%.

And much of this growth will come from low-orbit communication satellites.

Dr. Ying, we all know the advantages of low-orbit satellites, such as close to the ground, short communication delay, high data transmission rate, and light 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 magnified, and 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, they will inevitably be hunted by the patent holders of these frequency bands. "

Zhan Kunhu was worried about the future of this project, and Yingshu had also had a headache for this difficult problem?

But he had just been given a shot of adrenaline by Gu Qing, and he was ambitious at the moment, and there was no frown at all.

So, facing Zhan Kunhu's thoughts, Yingshu replied with a heroic face: "At this stage, we are just doing experimental exploration, and we don't need to be internationalized. We only need to maintain cooperation with the aerospace department. In the future, we can maintain technical support for the earth and outer space, as well as the two transit rest stations. These laws on the ground, no matter how strict they are, can't control our space field?

Otherwise, can they still shoot us down with satellite missiles? "

When Yingshu said this, Zhan Kunhu instantly felt something was wrong.

In previous conversations, the other party was knowledgeable and responsible, and spoke in a muffled voice, but today his mind was lively and jumping like a young man.

So he looked at the other party with a strange look.

But Yingshu did not notice his own changes. The senior staff of Jiuzhou Technology seemed to have similar changes after spending more time with Gu Qing.

They are increasingly susceptible to the words of their boss. Whether it is understanding things or doing things and academics, they will start to be different from the past for some reason. The unit draws a clear line.

Jiuzhou Technology has already passed the difficult time of accumulating capital in the beginning. Now it has entered a period of rapid development. How can Gu Qing not make "backhand preparations" for the rapid development?

It is no exaggeration to say that all the research and development achievements of Jiuzhou Technology are the seeds planted by Gu Qing, and these scientists, engineers, and even ordinary employees who "suddenly have inspiration" are gardeners and bees who water the seeds.

Taoyao is a magical drink that can invigorate the spirit, improve physical fitness, and repair physical injuries.

But no one knows that long-term drinking of Taoyao and contact with Gu Qing If they are touched, they will unconsciously regard Gu Qing as a patriarch.

The soul will 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" to delegate power, allowing engineers and scientists in his company to bring out the black technology developed by the team as long as they think the time is right.

Gu is not afraid of the investigation of those interested people at all, after all, the research and development teams of these black technologies are well-known.

…

The artificial satellite device, as its name suggests, has a variety of shapes, including spherical, spherical polyhedron, cylindrical, polyhedron, etc. .

At first, artificial satellites were basically spherical or spherical polyhedrons. The world's first artificial satellite, Sputnik 1, was spherical, and Daxia's first artificial satellite, Dongfanghong, was a spherical polyhedron.

This was mainly due to the limited payload and payload compartment size of early launch vehicles.

For the same volume, the surface area of ​​a sphere or spherical polyhedron is the smallest, which can effectively reduce the size and weight, thereby reducing the burden on the launch vehicle.

Subsequently, in order to install enough solar panels to "charge" the satellite, cylindrical or prismatic satellites gradually became the mainstream.

With the advancement of science and technology, and the increasing number of tasks that satellites need to complete, the equipment carried by satellites is also increasing, and the weight is increasing. Naturally, the energy required must also increase. Therefore, the current satellites directly separate the solar panels that power the power supply and make them a separate component, thus forming a modern satellite that runs in orbit with wings.

Jiuzhou Technology's low-orbit communication satellite is installed in the "head device" of the rocket. The mechanical structure is not much different from that of ordinary low-orbit satellites, but its appearance does not have those cables and redundant equipment that look "full of technology".

The attitude control system used is the traditional three-axis stable attitude control technology, which is an attitude control technology that makes the three axes of the spacecraft perpendicular to each other have the expected direction in space relative to a certain reference system, so there are no too stringent requirements for the appearance of the satellite.

But only the designers, developers and manufacturers of this satellite know how difficult the integration technology is hidden under the unprepossessing appearance of this satellite.

Although it flies out of the ground, it also has to abide by gravity, so the lower the altitude of the low-orbit satellite is compared with the high-orbit satellite, the greater the gravity.

Five years ago, the first low-orbit broadband 5G communication satellite with a communication capacity of 10Gbps, Galaxy Aerospace's first satellite, was launched into space.

Five years later, the unknown launch mission, the world's first low-orbit communication satellite for 6G small-area experiments will be launched into space.

The former carries professional equipment and instruments, while the latter, in addition to relevant professional equipment and instruments, also carries three small and medium-sized robotic arms, as well as a special launch device and a photographic device.

Elon Musk's "Starlink Project" SpaceX submitted a "12,000 Satellite Constellation" plan that states that the satellites of the Starlink Project are distributed in three low orbits of 340 kilometers, 550 kilometers and 1,150 kilometers.

The Daxia Space Station has encountered more than one "out-of-control" Starlink satellite in recent years, which not only affected the stable operation of the space station, but also interfered with some experiments, forcing the Daxia officials to come out and ask SpaceX to admit and correct their mistakes, but the other party just looked indifferent, which made some senior executives of the Daxia Aerospace Department speechless.

Therefore, when Zhan Kunhu, the head of Jiuzhou Technology's satellite R&D and manufacturing department, led the department's engineers and the company's think tank team to hold a meeting and negotiate, they unanimously agreed to install "defensive equipment" that can counterattack on their own satellites.

PS: Thank you for your recommendation and monthly votes.

Good night, everyone.

Goodbye, November.
