Super Weapon Swap System

It's not so easy to interfere with the Beidou system.

If you are a layman, it is easy to exaggerate. For example, a reporter vowed to use hackers to interfere with the Beidou system. In his eyes, he seems to think that the Beidou system is as easy to be disturbed as the computer network system.

Of course, this is impossible. The principle of satellite navigation system determines that hackers can't do anything. The principle of satellite navigation system is very simple. Satellites launched into the sky carry clocks and send clock signals to the ground.

Yes, it is one-way. It only transmits signals and does not receive signals at all. Since it does not receive signals at all, what means do you hackers use to enter it?

Ground passive reception determines the distance and calculates its own position according to the satellite's position and the transmitted time signal. I'm afraid only the satellite's orbit wants to interfere. If the satellite's orbit is wrong, there will be errors naturally.

The orbit of the satellite is monitored by the aerospace measurement and control network. This network is not connected with the civil network at all. Besides, after launch, the orbit of the satellite is fixed and will not change. How can it be adjusted?

As for changing the clock signal, it is impossible. After the calibration before going up, the error is only one second in hundreds of millions of years, so there is no need for calibration at all.

Therefore, it is impossible for hackers to invade. If they want to interfere, they can only interfere with the clock signal, so that users cannot receive or receive the wrong signal. These are two types: suppression and deception.

This kind of suppression is to send a large number of the same signals so that the target cannot receive normal signals. This method is very simple and rough. However, it requires a lot of energy. Even the electronic jammer has an operating distance of hundreds of kilometers. How much energy does it need to interfere with the satellite navigation of the whole country?

Deceptive should be further improved, that is, transmitting exactly the same signal, allowing the user to receive the wrong signal and interfering with the correct navigation and positioning of the receiver. This requires very little energy. However, it is absolutely not easy to understand the specific contents of the signals transmitted by the navigation satellite.

Now, the Beidou navigation system launched by the Han people has long been specially studied against interference. It adopts special space-time adaptive advanced anti-interference means to reduce the amount of computation and improve the convergence speed by reducing the degree of freedom of processing. At the same time, the beam control box beamforming technology is used to form a high gain beam in the direction of satellite signal in addition to forming a deep depression in the direction of interference. In this way, the satellite signal is enhanced while suppressing interference, and the anti-interference ability is greatly improved. This anti-interference scheme will not have corresponding jammers even by 2020. Therefore, if you want to interfere with your Beidou navigation system, it will be another 30 years!

The satellite is not a simple whip antenna or paraboloid antenna at all, but the most complex array antenna. The interference cancellation can be completed by using the characteristics of the satellite navigation signal, and the signal can not be distorted at the same time.

Since you want to interfere with our Beidou system, we can naturally do the same and interfere with GPS. In this way, the Beidou navigation system works normally, but GPS is powerless. Compared with the two, I believe the customer will have a correct choice.

Qin Guan thought of this and smiled. It's not so easy to come to us for trouble!

President Qin smiled? What's this guy thinking? If you are familiar with Qin Guan, you will know the meaning of his laughter. It is clear that it was only when people were entrapped. Scholars know that Qin Guan must have thought of how to entrap these guys.

"If you want to interfere, use it," Qin Guan said. "We can't take the initiative to cut off the signal provided by the region."

The most direct way to make the other party at a loss is to turn off navigation. The eagle people took advantage of their GPs. They didn't know how many times they had worked in that parallel time and space. Whoever didn't obey, they cut off their signal, so that they couldn't work and live normally, let alone fight. After all, the precision guided weapons at that time relied heavily on GPS.

The Han state will not do so. The navigation signal that the Han state wants to provide serves the whole world. If it is always cut off, isn't it hegemonic?

"Don't you dislike it?" ambassador green was puzzled and said something that diplomats shouldn't say. Shouldn't you be angry?

"Of course not." Qin Guan said, "I wish you success."

And wish us success? What does president Qin think? When Ambassador Green left, it was already dark.

After Ambassador Green left, Qin Guan's work here was officially started. He handed over the data of the B-2 bomber to Chen Lao and officially began the research on the stealth bomber!

After all, this is the most important thing. Now, it's time for them to have new scientific research projects. Keep motivated and beat up this big guy as soon as possible!

Qin Guan was full of confidence.

For the Han state, it is necessary to constantly study the war and adapt to the war, but for the participants, it is not so leisurely.

Happy desert country, coalition command.

"Damn it, the people of yezao country are like a smart commander. They have played for eight years and haven't seen them use this method!"

A commander cursed that in the eight year war, the date palm country and the Sabbath country used almost the playing method during the world war. Now how can you think that they actually used such modern means, and they also learned to saturation attack!

The loss of the eagle Navy is not particularly large, and new aircraft carriers are coming. They must win this war, but this loss is still unacceptable to them.

"Fortunately, we just got the information. There are only so many anti-ship missiles in yezao country. If they had another round, we would be crazy."

In the face of the people's comments, general schwapf also frowned. He is the supreme commander. What face does he have now? I'm afraid the boss is already considering replacing him?

"Now, it's time for us to use the big killer!" schwapf said. "We want to let the people of yezao know that we are a nuclear power!"

Schwapf's words immediately stunned the people below. General, have you made up your mind?

"Of course, now do we have any other means? Our conventional army has lost too much, and Congress cannot accept greater losses. Therefore, we must use our nuclear bomb to let the people of yezao know that there is no good end to confrontation with a big country!"
