Synchronous orbital space stations do maintenance work, and super satellites do communication base stations.

This idea is really good, and there is no technical problem, but it is really expensive, which is even more expensive than building more than a dozen international space stations at the same time!

In order to realize the global satellite Internet communication function, Musk has to launch a total of 12,000 satellites into the sky to provide low-latency and high-broadband network broadband services to global interrupted users. Moreover, the satellite must be close to the low-Earth orbit of the atmosphere and only 550 kilometers away from the earth's surface.

In fact, before the Starlink project was proposed, humans had long implemented satellites to provide Internet service in space. They are generally geosimultaneous satellites. The advantage is that they can operate fixedly over a certain area and have a very large signal coverage. In theory, only 3 satellites are needed to cover the global surface area.

However, the disadvantages of synchronous satellites are also very obvious, because their orbital height is 36,000 kilometers, which is almost 50 times that of low-Earth orbit. In addition to causing a long delay in communication signals, it also requires very large satellites to have sufficient energy. Therefore, the satellite-related costs will be very high.

First of all, the cost of launching satellites into the sky is a large expenditure. Secondly, the satellite will definitely be limited by the rocket carrying capacity and cannot exceed a certain weight and volume.

Even if the Cattle Star Group now has the [Earth Cannon] electromagnetic orbital launch technology, it can only reduce the launch cost, and cannot change the fact that satellites are restricted, which will inevitably affect the satellite communication capabilities and require the launch of multiple satellites to make up for it.

Secondly, the operation and maintenance costs of communication systems will be high. Not to mention the space station alone may drain the profits of Meow Star Group. After all, Mao Xiong, a powerful country in the northern country, is unable to maintain the normal operation of the space station, and can only allow it to land at altitude and fall into the sea.

So when Academician Ma and Zhou Lin saw Li Maoye’s plan, their first reaction was that it was too much money. It would definitely be difficult for Meow Star Group to achieve it. Even if it did it, it would not have much significance for a private enterprise.

Of course, Li Maoye could feel the two of them, but he did not stop to explain, but continued to introduce:

"The communication satellites in the sky are like ground base stations. The more they are laid, the better the coverage. Moreover, the fewer the number of users each satellite serves, the higher the bandwidth the users enjoy."

"If you want to solve the delay problem and bandwidth problem, you still have to have a certain number of low-Earth orbit satellites to form a communication node network to assist in communication signal transmission. The specific approach is to use multiple low-Earth orbit satellites to serve various regions around a geosynchronous satellite, and then the communication between each region is bridged through synchronous satellites!"

While Li Maoye said, he drew the earth on the whiteboard, several low-Earth orbit satellites and a synchronous satellite. The signal of the low-Earth orbit satellites covered the earth's area downwards, and then directly connected the synchronous satellites and the low-Earth orbit satellites in a straight line, and marked on it: "Laser signal!"

In other words, the communication between satellites can be achieved with lasers to achieve high-speed communication, thereby avoiding the disadvantage of excessive delay in radio wave signals. At the same time, since the position of the synchronous satellite remains unchanged relative to the earth, it is easy to achieve laser communication with near-earth orbit satellites.

Musk's Starlink plan has many advantages, but also many disadvantages. Among them, multiple satellites have to solve the communication problem between satellites and satellites by forming networks in the sky. Laser communication technology is a good means, but Starlink satellites operate very fast and are very close to the atmosphere. As long as there is a slight vibration and tremor, it will affect the stability of laser communication.

Only Li Maoye's combination method will solve the problem. By synchronizing satellites, it can form the regional core, and then each low-Earth orbit satellite passing through this area can quickly find it, and then be connected with other low-Earth orbit satellites.

If Musk's Starlink is a satellite network without a core, then Li Maoye's satellite network has a synchronous satellite as a core, while the low-Earth orbit satellite is the various port nodes of the network.

When he heard this, Academician Ma and Zhou Lin both understood, "Mr. Li, you are not optimistic about the Starlink plan, so you came up with this combination model, right?"

"Yes, Musk's Starlink not only has high maintenance costs, but also has low fault tolerance. The entire network system is extremely unstable. As long as some problems occur, it will affect the security operation of the entire network."

Li Maoye took pictures of the content on the whiteboard and continued to introduce: "My plan is completely different. With synchronous satellites as the core center, low-Earth orbit satellites can increase or decrease at any time, and the laser communication between them will be extremely stable, much faster than fiber optic cables on the ground."

Only in this way can we solve the problem of high radio wave communication delay of synchronous satellites too far from the ground, and make the entire system more secure and stable. As long as there is no problem with synchronous satellites, there will be no abnormalities in the entire network.

"But what about the cost issue?" Zhou Lin said he still had doubts.

"I will explain how to solve the cost problem later!" Li Maoye expressed his willingness to remain calm.

"If there is really no solution, you can consider asking the country for help, or cooperating with other companies as you said. I remember that the Aerospace Technology Group is forming the 'Hongyan' global satellite communication constellation system, and the Rabbit Science Academy also plans to jointly build a broadband satellite constellation with the Magic City. In addition, other commercial aerospace companies are also ambitious to carry out their respective broadband satellite plans..."

Li Maoye's explanation made the two vaguely see hope, especially Academician Ma can better understand the meaning of it. Such a large-scale project must of course be intervened by the state.

Academician Ma thought to himself: "This seems to be able to integrate domestic power?"

Zhou Lin thought that if this plan is supported by the state, it will inevitably reduce the pressure on the group itself, and at the same time, it can obtain a massive amount of funds similar to that of the Bald Eagle's R&D plan for the moon landing. At that time, regardless of whether the plan is successful or not, the Meow Star Group will not lose money.

As for whether it can obtain national support, Zhou Lin believes that there is no need to worry about this issue. As long as Li Maoye is willing to submit the plan and ensure technical support, it will definitely pass the review of the relevant departments.

After all, the current battle situation in the field of satellite communications is too chaotic, and there must be strong people to end this situation.

Not only Huayao Company is creating a Starlink satellite communications program, but other domestic organizations also have the same ideas, but they are all based on their own needs and abilities, so they are not as attractive as Musk's grand blueprint.

It seems that the country is full of flowers and flowers, but it seems a bit scattered and unruly. No one can concentrate his strength in one direction, so the bald eagle can defeat the world with just one Musk.

Li Maoye continued to say: "In fact, we have been trying to solve the cost problem. The space electric thrust engine that the laboratory is studying is a good technological breakthrough. Once this technology is completed, my planned cost can be compressed to a very small level. I will explain in detail below..."

He said while writing and painting on the whiteboard. Soon Academician Ma and Zhou Lin understood why the cost in this plan would not be a big problem, because Li Maoye did not plan to wait until the second phase of the project was completed and then build a global satellite communication network.

"This is to use the first phase of the project [Earth Cannon] to launch it. When it reaches the low orbit near Earth, it will use the space electric thrust engine to continue flying upwards. This not only saves a lot of launch costs, but also can launch satellite planning projects a few years in advance. The only prerequisite is to wait for the space electric thrust engine to be manufactured?"

Not only was Zhou Lin shocked by this plan, but even Academician Ma was so excited that he could hardly sit still. He quickly asked: "Academician Li, how big is the maximum thrust of the space electric thrust engine you mentioned?"

In fact, Academician Ma is not unfamiliar with space electric thrust engines. A few years ago, the 801 Institute of the Sixth Academy of Aerospace Science and Technology Corporation had developed the first 20-kilowatt high-power Hall thrust, and all performance indicators reached the international advanced level at that time.

However, such an advanced Hall thrust is not very useful, because the maximum thrust is only about 1 knot. If it can be installed on a small satellite in a small size, it is still a good choice. However, if you want to use it to promote a super-large satellite or space station, it would be a fool.

Li Maoye first calculated it in his mind and quickly replied: "The space electric thrust engine has not been manufactured yet, but according to my design, the maximum thrust should be more than 1,000 N!"

The space electric thrust engine is different from the electric thrust engine in the atmosphere, so the thrust will be smaller, but the difference will not be too much. Since the drone electric thrust engine in the design can accelerate a 200 kilogram aircraft to a speed of Mach 3, the thrust will certainly not be too small.

After hearing this answer, Academician Ma couldn't sit still, "Is there really 1,000 calories? If there is such a great thrust, then we really have to modify the original plan."

Zhou Lin doesn’t quite understand the difference between 1 cow and 1,000 cow, but he also understands from the numerical perspective that this is another black technology, which can definitely change many things in the world.

"Maybe this is a good time for Meow Star Group to enter the aerospace field?"

When Zhou Lin's heartbeat could not help but accelerate a lot when he thought of this. After all, men had dreamed of rushing out of the earth to conquer the universe. Even the Great Elder once said: "Our journey is the sea of ​​stars!"

It can be seen how inspiring this dream is. From ordinary people to superior rulers, they have always been thinking about realizing their dream of the stars and the sea.

Since it is a dream, it means it is unrealistic!

But now to Li Maoye’s words, it seems like an extremely simple thing, but it can be convinced.
Chapter completed!
