V1.Chapter 711

"It can be said that since the day when the first positioning system was established in the world, we have been faced with such risks.

After all, these satellites are artificially launched into outer space, and our current understanding of outer space is not as thorough as we thought, or even half understood.

There are many kinds of dangers faced by the networking satellites.

There are deliberate attacks by hostile forces, more and more frequent launching missions by various countries and other factors.

For example, there are nearly a million satellites carrying out various missions in the outer orbits of the earth.

Although the first satellite has its own orbit, trajectory and speed, no one can guarantee that there will be no satellites deliberately launched by hostile forces against one side.

Moreover, these nearly one million satellites are operating in outer space at the same time. On the one hand, they are overcrowded; on the other hand, because there are too many satellites, the signal transmission and accuracy of some positioning satellites are affected.

This is the same as the overpopulation in the city. With more people, it is inevitable to crowd and collide with each other, and it is easy to affect the sight of other people. Today's positioning satellites are also facing such problems.

Of course, this is only human factors, or non-human factors.

For example, meteors, meteors, solar magnetic explosions and unknown radiation in outer space will have an inestimable impact on positioning satellites!

But these are unavoidable factors. Even if we know that there is no better way to solve them with our current scientific and technological means! "

The twin brothers explained to Xu in the simplest language, trying to make Xu understand what they meant.

Although Xu is not a professional in this field, he also understands the meaning of twin brother.

That is to say, what Chen qianggang just said is indeed a fact.

Of course, in terms of human factors, in order to ensure their own people's livelihood and national defense, countries will try their best to avoid deliberate friction before they have a better solution.

But in the non-human aspect?

As far as Chen Qiang knows, during the period when the earth entered the Reiki recovery period, there was a long positioning window period in geospace.

Because in the process of escaping to the holy land, the blood devil inadvertently brought massive aura to the earth space, but at the same time, it also destroyed almost all kinds of satellites in extraterrestrial space!

Of course, Chen Qiang will not make it clear, but the non-human factors mentioned by the twin brothers just now actually include this situation.

"As you said just now, there are certain defects and hidden dangers in the satellite positioning system.

But the communication Bracelet in our hands now is the receiver of another positioning system.

As for the specific situation of this positioning system, I don't know much about it, but I've heard about some working principles.

Just now, you have also said that relying on satellites as the signal transmitting source of the positioning system takes into account the fact that the earth is a sphere. In this way, the signals emitted by the networking satellites can form the intersection point, and then form the positioning function.

But the signal source of the positioning system of this communication bracelet is hidden in the sea.

Moreover, these signal transmitting sources are arranged in the sea, and the wave bands emitted are also accompanied by super infrasound waves!

This is because there are countless creatures in the sea, and the super infrasound wave will naturally make the creatures in the sea have a sense of fear.

Of course, in fact, super infrasound waves are destructive to marine organisms. Therefore, there is no need to worry about the destruction of these signal sources in the sea, and the depth of the arrangement is only one kilometer.

On the one hand, the earth has a large area and is not easy to be found. On the other hand, at such a depth, it will not be found by enemy forces, thus avoiding the possibility of man-made destruction.

Of course, the non-human factors mentioned by the two just now are even less likely to happen.

In addition, due to the medium, the power and intensity of Hisense signal source is not as accurate as that of outer space. I think this is also a problem, right?

After all, the refractive index and penetration of different media need to be considered. Therefore, the technicians who invented the positioning system used the micro nuclear fission device as the energy source, and the signal emitted was ultra short band ∑ ray.

Because the frequency band of Σ - ray is the shortest, and the transmitting frequency has reached a very high level, it has the same effect as Cunquan, transmitting the signal into the air step by step, forming a cross with other signals, and then having the function of positioning.

This is the basic principle of our communication Bracelet positioning system. Of course, I'm not very clear about the details. "

Chen Qiang said these words at the same time, the twin brothers have been listening carefully, and synchronous recording.

After all, Chen Qiang's idea of such a positioning system was put forward decades ago, but it can not solve some specific problems.

For example, as Chen qianggang just said, seawater medium, refraction, characteristics of the earth's sphere, energy source and other factors.Of course, there is another point that Chen Qiang did not mention, that is, materials.

"Brother Chen Qiang, I understand what you said just now, and now it's not a problem to make micro energy source, but the material to make signal source..."

Chen Qiang stopped in time and said, "as far as I know, it's not a problem. I remember that just four years ago, our country discovered a new type of high-density nano composite material, which is the most suitable signal source and can prevent instant high-strength stamping. Can the signal source made of this material at least guarantee that it will not be replaced for hundreds of years?

And the most important point is that if this kind of positioning system is successfully developed, the step of transfer station can be omitted. It can be directly received by this kind of communicator and automatically positioned.

Of course, as for this point, you have to go back and dismantle the communication Bracelet before you study it. "

What Chen Qiang said is still a little conservative.

Because his communication bracelet is an example.

The signal source that provides signal transfer has not been replaced since it was developed.

When Chen Qiang finished, one of the young people's eyes suddenly brightened.

"Brother, are you talking about qc483 composites? I remember that this is a kind of material between liquid and solid, which is now widely used in individual protective equipment of various countries.

But I never thought that this kind of material could be used in the signal transmitter

Chen Qiang laughs at Yan, "it's easy to understand. After all, the problem faced by the research and development of Shenwei's positioning system in the sea is not only the material, but also normal. "
