Because there are so many places that can be used in orbits over the entire earth, this amount is relative. If you launch some individual satellites into the orbit, of course, the problem is not big, but if you launch a star like a space exploration company The high-density networking satellites of “Chain Project” are troublesome.

This kind of networked satellite has certain requirements for the distance between the satellites and the division of the area that the satellite passes through. It does not mean that the satellite is launched into the orbit in a single brain, so the orbital resources of these satellites can be used. It is a relatively important resource.

Then the problem is coming. For networked satellite launch plans like the Space Exploration Company’s “Starlink Project”, they have so many satellites to be launched into the sky. This time must be very long, and it is impossible to do it all at once. Thousands of satellites were launched in a short time.

And if their company takes these orbits ahead of time, obviously this is the most desperate thing. Without these orbits, their subsequent launch plans will be greatly adjusted or even suspended. The loss is indeed greater than the tens of billions of dollars in space waste disposal business lost by their company!

It should be known that in addition to the well-known communication network construction plan of the Space Exploration Company’s Starlink Project, there are several similar communication networking satellite launch plans in Europe and the United States, and the amount of funds involved in each of these plans is It started with ten billion dollars.

If these related plans are interrupted by the interference of Infinite Gravity Group, the loss is not just a matter of money!

"Boss, this idea is really possible! And our laboratory can do better. With our current communication satellite technology level, it is clear that we do not need to be the same as the Starlink Project of the Space Exploration Company. To launch so many communication satellites to form a global high-speed communication network.

I simply calculated that even if we only launch 10,000 of our communication satellites, the high-speed communication network formed by our company is much better than theirs, regardless of the signal strength, data transmission speed, or other indicators. A lot of.

Anyway, according to your boss’s idea, we don’t seem to need to launch as many as tens of thousands of satellites, as long as our satellite orbit is right at the center of the orbit node they need, so they can only do a large scale if they want to network. Adjusted.

Because our company’s communications satellites do not only occupy one key node, but tens of thousands of such nodes, they cannot avoid our interference in any way.

If the boss wants a better combat effect, we can even add some interference frequency bands when designing our communication satellites. This kind of thing is still very simple for us.

In this way, even if they want to deploy satellites near our satellite orbits, it will not work, because our satellite signals will seriously interfere with their satellite communication signals.

Anyway, when the time comes, we will say that our company's design has made an omission, but at that time our tens of thousands of satellites are floating in the sky, who can force us to scrap these satellites! After Chen Shuming slapped his boss's flattery, he began to put forward his own optimization suggestions.

He said this of course because of his confidence in the technology of the laboratory he manages, and his judgment of the situation is also very accurate.

Don’t look at the number of satellites in operation in the entire Earth’s orbit. It seems that there are very few for such a vast space and airspace of the Earth, but the orbital resources that can be used are really very limited. This question needs to explain how the satellite orbits are distributed.

Because of the existence of the Van Allen radiation belt, the distribution of satellite orbits can only be divided according to the distribution area of ​​these radiation belts.

The so-called Van Allen radiation belt refers to the trapped radiation area around the earth. This area is composed of high-energy electrons and protons in the solar wind captured by the earth's magnetic field. They are divided into three layers, each of which has a permanent ribbon structure. There is a vacuum zone in between.

The first layer has a range of 1500 to 8000 kilometers, the second layer has a range of 15000 to 25000 kilometers, and the third layer is still under study.

These radiation areas will cause more damage to the satellite's electronic equipment and equipment, and protection is more difficult, so satellites need to avoid these radiation belts.

Satellite orbits are divided into low-orbit, medium-orbit and high-orbit satellites according to the first and second radiation zones. Of course, there are oblong orbits (special orbits): mainly used to cover the north and south poles. The perigee of the orbit is about 500 kilometers high and the apogee is about 40,000 kilometers high.

Due to the existence of the Van Allen radiation belt, the orbit height and the need to reserve a certain distance to prevent frequency interference, the total number of satellite orbit resources is limited.

Frequency interference is also a problem that must be paid attention to. Take the geostationary orbit as an example, the entire earth is just one orbit, and everyone wants it.

Generally speaking, the longitude between two medium-capacity satellites is not less than 2 degrees. If one satellite is placed at 2 degrees, a maximum of 180 satellites can be placed in a 360-degree circle, and the resources are quite limited.

Of course, there are far more than 180 orbits now. Infinite Gravity Group is planning to build two large space ports here in the future. Just think about how crowded it is!

So in order to solve this problem ~lightnovelpub.net~, certain technical means need to be adopted, and two technical means are mainly used now.

One is the orbital co-location technology, that is, placing two or more satellites on the same orbital position. However, this technology needs to achieve precise control of the orbit by ground measurement and control, and break through the optimization of orbital position, position preservation strategy optimization and precise measurement. A series of key technologies such as rails are currently only mastered by a few countries in the world, such as Lao America, China, and Baga.

The other is to allow two closely spaced satellites to use the communication frequencies of different frequency bands, thereby increasing the utilization rate of the orbit. This is what the ITU Radio Regulations need to do. It is the coordination frequency that does not interfere with each other. The meaning of existence, frequency is not just how you want to use it.

And this is where Chen Shuming wants to do his hands and feet. I won’t talk about it in the geostationary orbit. Of course, we must pay attention to avoiding the frequency interference between the two satellites in the non-stationary orbit.

If you really follow Chen Shuming’s suggestion, the satellites they launched can not only occupy key orbital nodes, but also the signal interference frequency on the satellites can also prevent those satellites who want to get close to this orbital position. Tiantang thinks even more absolutely!
