"How can I fly back in secludedly?" Iran could not leave anymore. In the original plan, there was a first refueling there, and then Pakistan would take the second refueling and China would take the third refueling, and there would be basically no problem.

After all, there are still a large number of aerial refueling aircraft in the entire flight formation, which can continuously refuel fighter jets with insufficient range.

If you want to be concealed, it is not a problem when there is no satellite system covering the world in the sky.

At least, it's not a big problem.

Now, this problem is difficult to effectively solve.

If you are not careful, the spy satellites passing by above can clearly discover the entire huge fighter jet formation.

Just like the nuclear-powered aircraft carriers that the Soviets are now building, since their docks are open, from the beginning when the keels are laid, American spy satellites kept taking photos of the aircraft carriers and then kept observing the progress of the Soviets.

The whole world is very clear about the progress of the aircraft carrier built by the Soviets.

In order to get the people to support the government in fighting the evil Soviet Union, let the people pay more taxes and the government continues to develop arms by expanding the fiscal deficit, Western media will naturally present the threat from the Soviets.

"Contact there, didn't Yu Ping know a lot about the American satellite system and the Soviet satellite system?" Liu Suxue had a headache, and Liu Yijiu also had a headache.

However, Liu Yijiu gradually had an idea.

Although American satellites cover the world, they do not monitor the world all the time. If that happens, they will basically be unable to play.

Any moves will be known to them.

In the US global satellite system, not all satellites have the functions of spy satellites. Even if they have them, these satellites can only take photos of a certain area at a specific time. After passing by, they have to circle around the earth before coming.

Of course, there are also stationary satellites that synchronize the earth's orbit, but the positions of the Earth's orbit synchronous satellites are fixed and are mainly used for communication and large-area surveillance.

"Last time, Yu Ping had already closed the back door left in the US satellite system..." Yin Xianping was a little puzzled.

Liu Yijiu had no explanation.

Instead, he asked him to contact Liu Suxue and asked Yu Ping to go to China. After receiving the reply, Liu Yijiu went to find some big shots in aerospace for research.

"What? To figure out the orbit of each satellite in the US global satellite network system?" Some technical experts who stayed at the Ninth Hospital to communicate with them about the Beidou system were stunned.

"Director Liu, do you know that this is the most confidential thing in every country!"

"Even if we know, there is no way. Can we have any weapons to kill these satellites?"

A group of technicians did not understand why Liu Yijiu wanted to figure out the satellite trajectory of the US global satellite network, and that it was too difficult to figure out the trajectory of the US military spy satellite.

Ordinary radars used for air defense on the ground are not possible to detect satellites in space. Large radar stations, or monitoring stations used to monitor the sky, are obviously avoided by the opponent's satellites.

The trajectory of spy satellites is more confidential than that of military communication satellites.

The orbit of this thing is very low, only a few hundred kilometers away from the ground. If the missile technology is better, it is possible to kill it.

However, this is not something China can handle at present. In terms of satellite development, the military spy satellite technology is not as good as the three synchronous orbit static satellites of the Beidou system.

"You kid don't want to build a radar that specializes in satellite detection to knock out all the foreign satellites in our airspace, right? We have created a satellite detection radar, but we don't have weapons to reach. Isn't this even more annoying?" The technicians were really unacceptable to Liu Yijiu's idea.

There are satellite monitoring ships in China, and large satellite monitoring stations have been built in some key places in China. Some spy satellites from the United States and the Soviet Union can be discovered, but there is no way to get these satellites down.

China itself is not even capable of launching spy satellites, and it is even more difficult to kill them.

"If we make a breakthrough in laser weapons, just find out the trajectory of foreign spy satellites and shoot it down, it will not be too difficult!" When everyone thought Liu Yijiu was crazy, an old man pushed his glasses on his nose and expressed his support for Liu Yijiu's idea.

Wang Daheng, the father of optics in Chinese lasers in history.

Liu Yijiu looked at them in surprise, wanting to tell them that in fact he just wanted to find the trajectory of the US spy satellite network, and then look for a route they could not detect, and stolen Ukrainian planes and missiles.

They were very good. After they proposed this, they directly thought of shooting down spy satellites that were passing by the Americans and the Soviets over China!

Who says Chinese researchers are not crazy?

At least, Liu Yijiu doesn't believe they are not crazy.

"Everyone, is there any way?" Liu Yijiu asked them.

Domestic satellite monitoring stations can actually detect most spy satellites, but these satellite monitoring stations do not cover all areas across the country.

"There is no way, but we cannot detect all satellite networks, especially spy satellites." Sun Jiadong, as the head of China's No. 1 satellite, is absolutely a big shot in satellite technology. After thinking about it, he said, and then asked Liu Yijiu, "Xiao Liu, has our laser weapons really made a breakthrough?"

"Is the Ninth Academy studying laser weapons?" someone asked immediately in surprise.

It was like throwing a high-explosive bomb into the calm water, and it instantly rushed into huge waves.

The Ninth Academy has laser research, and they all know it, especially the expert Wang Daheng, but he would not have thought that the Ninth Academy’s research on lasers is not used for detection or something, but for developing towards weapons!

However, this is nothing strange.

"Everyone, I just want to figure out the satellites of the United States and the Soviet Union above us. You are all thinking too far..." Liu Yijiu said helplessly. "Although, I also want to capture foreign satellites. After all, outer space is also our airspace. Extending from the land area is our territory!"

Liu Yijiu's words are very domineering.

The sky above the country belongs to China's airspace, which everyone knows. The airspace of other countries cannot be violated, and that is a matter of sovereignty.

However, no one thinks that tens of thousands of kilometers of outer space above the airspace of other countries is sovereign.

Even in the airspace of various countries, as long as you have the ability, you can capture these satellites!

Not to mention that there are no missiles with such a long range in the world. Even if there are, can they be shot?

After all, when satellites are launched, they are not just used to send them to space through launch vehicles. Many satellites need to rely on the tangent force generated by the earth's rotation and the gravity of the sun to send the satellite into a predetermined orbit.

"Yes, outer space is also our airspace! We should safeguard our airspace sovereignty. Their satellites pass through our airspace, but they have not dealt with us..." I don't know who said this.

Seeing that the more troubles became more and more outrageous, Sun Jiadong couldn't help but say seriously, "Comrades, let's be more realistic. Do your own essential work well, complete the second phase modification design of the Beidou satellite system, and also have a satellite network covering the world later..."

That kind, just think about it.

Liu Yijiu was a little helpless. He seriously suspected that these old men had not left the mountain for too long and had mental abnormalities.

While thinking about asking Zhao Min's team to give them a thorough inspection so that there would be no problems, and the losses would be huge.

I originally wanted to communicate with them and discuss how to find all the American satellites, especially to monitor the situation of the route from Central Asia to China.

Only after finding it out can you formulate a route to return to China.

If it is just a spy satellite used for census, it is not easy to be discovered. If it happened to be photographed by the detailed spy satellites of the United States or the Soviet Union on the flight route, the plans for so many years will be in vain.

"Old Li, Mr. Yang, if we have signal reception and transmission equipment and know the communication frequency, can we control the satellites passing through our sky?" Liu Yijiu ignored the other old men and asked Li Jie, who was responsible for the computer here and Yang Jiaji, who was responsible for their automatic control of manned space flight.

"If you know these, you will definitely be able to control them. The question is how we know!" Both of them looked helpless.

Liu Yijiu should know better than them the need to invade satellite systems in other countries.

China's satellite systems are also designed to consider foreign invasions, so the protection is designed very strictly.

Even the software encoding used is different from that of domestic civilian promotion, but only used by the military, which is because it is worried about being invaded and controlled. This is proposed by Liu Yijiu himself.

Immediately, Yang Jiaqi looked at Liu Yijiu with his eyes lit up, "You got their satellite communication frequency?"

"I didn't get it, but someone got it. That person will soon enter the mountain. At that time, I hope everyone can cooperate with him and find out the satellites of other countries above our heads..." Liu Yijiu did not tell the truth, but he did not tell lies.
