MTL - Warship of Great Power-Chapter 779 How to jam GPS

  Chapter 779 How to interfere with GPS

   "Accurate capture on target!"

   "Go into lock!"

   "Missile launch!"

   It is still an exercise, until the missile is launched, but no missile will actually fly over, even if it is a training bomb. After all, the stealth machine above the head is more precious.

  When the missile soldier pressed the missile launch button, everyone got excited.

   "Successful!"

   "We have the ability to shoot and kill stealth aircraft!"

   "Yes, it is true that the stealth machine can be killed, but it is only when the stealth machine opens its bomb bay." Zoltan-Danny said, he was not as excited as his subordinates, and at this moment, his face was a little lonely.

They expect their equipment to successfully intercept the stealth aircraft, but they don't know whether the target this time is too advanced or it is difficult to intercept the stealth aircraft, so they did not intercept the stealth aircraft perfectly. Everything is just the stealth machine releasing water.

  The key is the lack of meter wave radar! Chen always knew that if there was a meter wave radar for long-range early warning, it would be perfect to capture the target's trace in advance, and then let his own missiles hit it.

  However, meter-wave radar detection of stealth aircraft is still highly confidential, and this technology will not be exported for the time being. Therefore, the missile force in front of us must not have more advanced anti-stealth technology.

   Now, how to comfort them?

   "Everyone, after this exercise close to actual combat, I think you have summed up the tactics." Qin Tao said.

  Summary, what is the summary? Danny's face was very ugly: "Boss Qin, if the US-made stealth aircraft also has this capability, it means that it will be difficult for us to shoot down the stealth aircraft in actual combat!"

"Yes, these years of wars have taught us that stealth aircraft are the main threat. Our country's air defense capabilities are even worse. If we cannot destroy stealth aircraft, the sky above our heads will be undefended. As an air defense missile soldier , we will be ashamed!"

   "Everyone, if the stealth machine appeared above your heads, what would they do?" Qin Tao asked.

"What else can we do? They will definitely throw bombs at us and attack important targets in our country." Danny said, his tone was very excited and angry, but when he finished speaking, he seemed to have discovered What.

"That's right, if it flies over the target we want to protect, it will definitely drop a bomb. As long as the bomb is dropped, the hatch needs to be opened. No matter what stealth aircraft it is, when the hatch is opened, the stealth ability will be activated." Destroyed, this is our hope!" Zoltan-Danny was already excited when he said at the end: "The mission of our 251 Missile Brigade is to shoot them down!"

"We don't know what level the other stealth opportunities have reached. Maybe the opponent's stealth ability is worse than ours, and your usual training will come in handy. Maybe their stealth ability is better than ours, but that's okay. You just have to wait patiently, just like a hunter waiting for his prey." Qin Tao said: "Wait for the most suitable opportunity, and then kill with one blow!"

Zoltan-Danni nodded vigorously: "Yes, we have this confidence. Other anti-aircraft missile units will be responsible for various non-stealth targets, while our missile brigade only deals with stealth aircraft! We want to break the myth of stealth aircraft, Let the whole world see our chance to protect our country's airspace!"

  Qin Tao nodded: "I wish you success. Next, we will continue to study the enemy's next move after you shoot down the enemy's stealth plane."

   What's next?

  Everyone became serious.

   That's right, laying down the stealth machine is just the first step. What will happen next?

  The country whose stealth machine was shot down will definitely not be reconciled!

   "Boss Qin, if you have any suggestions, just say so."

"Although we try not to expose our weapons and equipment, some people will become angry after you shoot down the F-117. They will definitely investigate and find out that they are our weapons." Qin Tao said: "Then Down, they should take their wrath on us."

   "President Qin, please rest assured, we will not reveal the secrets of the Kaishan missile." Zoltan-Dani said.

   Dongfang provides equipment for them to defend their home and country, so can they still betray Dongfang?

Mr. Chen didn't think too much about it. Now that he heard Qin Tao say this, he felt sweat on his back. Yes, those guys would definitely blame him. He only thought that the Kaishan missile was famous and could be sold There are more, but I didn't expect to be retaliated against.

   What if you are retaliated against?

"There is no impenetrable wall in the world." Qin Tao shook his head: "Once you get the results of the battle, you must report it. You can be sure that you and your troops will not leak the secrets, and you can ensure that you are eligible to see this battle report. Don’t the people in this country leak secrets? No matter in any country, there are scum.”

  Zoltan-Danni was silent, yes, there is indeed this possibility.

   "Then what should we do? We don't want to implicate our friends in the East! We would rather not shoot down the victory."

   "Of course, and we must severely attack the invaders." Qin Tao said: "Please rest assured, even if you are implicated, we will stand behind you. We believe that there is still justice in this world."

  All the people who came to the missile brigade for training felt a warm current pouring into their hearts.

"Back then, we had just founded our country and were surrounded by foreign enemies. The leader at that time said a word, all the **** are paper tigers! Now, this sentence is also given to you, and I hope you can win!" Qin Tao encouraged .

   "Yes, Mr. Qin, please advise."

"At that time, the place where we orientals gather may be supplied by the other party. F-117 is smashed into the sand. They may send B-2 over. You deploy nearby. When B-2 drops bombs, put B-2 down!"

  What is F-117?

   Zoltan-Danny nodded: "Mr. Qin, please rest assured, we will definitely do what you say!"

  Spring is expected to be steep and the mountain wind is slightly cold, but everyone's heart is very hot.

After getting into the car, Xu Zhengyang said hesitantly: "Mr. Qin, I have traveled all over the world with you all these years, and everything you predicted has become true. Now, you are predicting another big event, which is true. Will it happen?"

   "Zhengyang, don't treat me as the Prophet Emperor." Qin Tao said: "I just analyze and judge based on the information I have, and finally get a more reasonable inference."

   "Brother Tao, what else can we do next? Should we withdraw our people?" Zhao Ling was also very nervous.

"Whether to withdraw or not is not up to us to decide. Besides, even if the superiors ask them to withdraw, they may not come back. We are truly Chinese, and there is no coward who will always stick to his post and uphold justice." Qin Tao said: "What we can do is try our best to pave the way for them."

  Zhao Ling nodded. Qin Tao's arrangements just now were indeed foreshadowing. However, the stealth machine was fired when the opponent's bomb bay door was opened. Even if the stealth machine was shot down, the bombs would still fall!

   "Next, let's go to the technical school."

   "Technical school?" Zhao Ling was curious.

   "Boss Qin, the technical school has been renamed a long time ago." Xu Zhengyang said: "The former radio technical school has now been renamed Guizhou Electronic Information Technology College."

   "Oh. It seems that a lot has been improved." Qin Tao sighed.

   "Of course, the entire 083 base is now renamed as China Zhenhua Electronics Group Co., Ltd."

   "This technical school belongs to the 083 base? Then I have an impression." Zhao Ling said: "In recent years, their third-line base has also been working hard to develop."

  The Kaishan that everyone saw just now is the product of the 061 Base, and the Shuangyang Aircraft Factory contracted by the Mingzhou Group is from the 011 Aviation Base. These were all produced during the third-line construction period.

  At the beginning, facing the serious threat from the north, in order to avoid losing military strength in the war, the country decided to transfer to the third front, and your province was the key construction area. In a triangular layout, the country has established three major bases. In addition to the 061 Aerospace Base and the 011 Aviation Base, it is the 083 Electronics Industry Base.

In the war years, the third-line bases can preserve their strength, but in peacetime, the third-line bases become a drag. After all, the third-line bases are located in the mountains, and the transportation is inconvenient. It is only the transportation of raw materials and products. It is enough to toss, not to mention talents, the talents of the older generation are willing to contribute their youth and life to the motherland in the mountains, who is willing to drill into the ravines of the new generation of college students? If you go in by yourself, what about your next generation?

Therefore, in the 1980s, the third-line bases were rapidly declining. However, they were also actively saving themselves. The 061 base was engaged in Kaishan missiles, the 011 aviation base was engaged in JJ-7, and the 083 electronic industry base was not idle. They did it. Various civilian electronic products, and later, Zhenhua Electronics Industry Company was established.

  This company has developed several times. It went public in 1997 and was restructured in 1999. It can be regarded as developing well.

  At the same time, the technical school attached to this base is also changing.

Just like the Mingzhou Group opened a technical school to train talents, the technical school in the 083 base is also to train follow-up talents. After all, it relied on the assistance of other units at the beginning, but the follow-up cannot continue to allow blood transfusions from brother units , which requires their own hematopoietic ability.

Moreover, this technical school also has a story. In 1975, the famous General Wang, who was in charge of the four-machine gun at that time, visited the 083 base and personally instructed the 083 base to establish a technical school to train electronic technical personnel. After that, ZY Radio was founded. Technical School. In 1979, ZY Radio Technician School moved to the old site of Duyun 1036 and was renamed as Duyun Radio Technician School. Now, the technical school has developed into a college.

  Hearing this, Zhao Ling was very moved, but she was still a little curious, what did Brother Tao go to the technical school for? Looking for technical poetry?

When it was dark, the car drove to the technical school. At the gate of the school, there were already a lot of people waiting to welcome them. Beautiful female students lined up outside, with red silk cloths hanging diagonally on their chests. Qin Tao couldn't help but wrinkled frown.

  I didn't intend to engage in such a big battle.

   "Mr. Qin, you are welcome to inspect. I am the principal here, so you can just call me Old Wang." Principal Wang said to Qin Tao with a smile.

   "Old Wang, our technical school is a national key technical school, a place to train talents in electronic technology. Why do you have so many welcoming ladies?" Qin Tao said: "Do things in a high-profile manner, and behave in a low-key manner!"

   "Yes, yes, Mr. Qin, you are right." Principal Wang nodded: "Remove all our welcome staff, low-key, low-key!"

   "Mr. Qin, it's getting dark now, and you're tired all the way here. Do you want to have dinner first? We've prepared it for you..."

   Originally, he wanted to say that a welcome banquet was prepared, but seeing Mr. Qin like this, he probably didn't want to go to such a lively occasion, so he hesitated.

   "Go to your cafeteria and eat whatever you want." Qin Tao said: "I will eat whatever the students in your school eat, and I will also experience the life of the students."

   "Okay, we will accompany you."

   "By the way, is there a group of people working on jamming machines in our school?"

   "Yes, this is a project we undertake for the army, and it will be led by the director of our electronics department, Lao Yang, Lao Yang, Lao Yang!"

  Yang Weiguo stepped forward: "President Qin, I can report our progress to you at any time."

   "Then let's have dinner together. After dinner, let's have a meeting."

"yes."

Every time he enters the university campus, Qin Tao will have a unique feeling. The students who are hurrying with their books, the students who stand in front of the grass and read English aloud, and the students who read books while eating in the cafeteria, all make Qin Tao I feel that the name of this college student's favorite son is not called for nothing.

Of course, Qin Tao will not go to places such as Internet cafes. After all, the big waves washed the sand, spent four years in college, and then couldn't find a job after graduation. People like me who feel emotional after going to university or university still have to find the reason from themselves.

  No matter what environment you are in, you need to work hard.

   "Boss Qin, we have fried rice in the cafeteria. Would you like to try our chef's skills?" Principal Wang asked.

   "No need, I think the ones in this window are pretty good." Qin Tao said, "One serving of braised pork, one serving of scrambled eggs with tomatoes, another serving of Kung Pao Chicken, and the staple food is three taels of rice."

  Principal Wang on the side was a little surprised. Does President Qin often go to university to experience life?

  The aunt who cooked the rice didn't shake her wrists, and the three dishes were filled to the brim.

   "President Qin, our fish in sour soup is not bad, it is a specialty of our province." Principal Wang said, "Would you like to have a taste?"

   "No, I'm afraid I won't be able to eat all of these, so I can't waste food." Qin Tao said, walked to the dining table with the plate in his hand, and sat down on it.

   "Principal Wang, Lao Yang, you don't have to be stunned, you should all eat together, otherwise it would be boring for you to watch me eat."

  Mr. Qin is the boss of a multinational corporation. He didn't expect to be so low-key and eat so simple. President Wang and others were very moved. He really did something big, and his realm was different from ours.

   "Yes, yes, let's eat too, Mr. Qin, what would you like to drink?"

  Moutai is a specialty of your province, so they have prepared Moutai for a long time, but in this scene, it seems that it is not appropriate to drink Moutai.

  Qin Tao looked around and saw the drink bottles next to the dining tables of several students: "Give me a bottle of that drink."

   "Mr. Qin, that's bayberry juice. I'll get it for you." The person in charge of the cafeteria has been standing by the side, laughing so hard that his face is cramping.

  It's so approachable.

   After dinner, Qin Tao looked at a large group of people around him: "Principal Wang, you can leave, you all go back, Lao Yang, just take your people and go to a meeting with me."

  Principal Wang's face is a little embarrassed. Mr. Qin must have a purpose for visiting their school. After he came, he didn't let him, the principal, attend the meeting?

He was a little upset in his heart, but he couldn't show it on his face, so he could only smile awkwardly: "Okay, Mr. Qin, then we won't follow, Lao Wang, report to Mr. Qin carefully, and cooperate well with Mr. Qin. "

  Yang Weiguo was flattered.

   Came to the meeting room, Yang Weiguo asked cautiously: "Mr. Qin, do you have any top-secret tasks for us to arrange?"

   "It's not a top-secret mission, I just want to hear about your progress on GPS jammers."

  Yang Weiguo realized in his mind: there must be a top-secret mission, something that even the principal would not be comfortable listening to, and he is directly responsible to Mr. Qin.

   "Okay, Mr. Qin, I will report to you in detail."

  With the development of technology, satellite navigation has played an increasingly important role, not only in the civilian field, but also in the military field.

  From the navigation of aircraft to the positioning of bombs, etc., satellite navigation has become a crutch for some military powers, and it can no longer be thrown away!

When the equipment that improves the bombing accuracy to the meter level with the help of satellite navigation terminals appears, it means that the cost of precision bombing will be lower. A small GPS receiver plus a control kit can cost only a few hundred dollars. Iron bombs turned into precision-guided bombs!

  However, as the dependence on satellite navigation increases, some superpowers will also become more vulnerable. As long as their satellite navigation system is solved, they will become blind.

The most direct way is of course to destroy satellites, but this approach is also very extreme: so far, space is still peaceful, once the opponent’s satellites are destroyed, the war will expand to space, and the destroyed satellite fragments are getting more and more If there are too many, the outer space of the earth will be full of debris, and human spaceflight will be greatly affected.

  So, we can only find a way from the ground.

   "At present, there are two solutions to the satellite navigation system." Yang Weiguo said: "They are interference and deception."

"Among them, jamming is the simplest technique. As long as a sufficiently strong RF signal is generated to drown out the signal transmitted by the original navigation satellite, the satellite positioning system can be invalidated. However, this is also easy to be discovered, because the attacker You will also find yourself disturbed.”

The satellite navigation system sounds tall, but the principle is very simple. The satellite above the head transmits the time signal, the receiver on the ground receives the signal, calculates the distance according to the time, and adds the orbital position of the satellite to determine the position of the receiver through geometric figures. .

  So, as long as the time signal is interfered, the receiver cannot receive the correct time information, so naturally it will not be able to accurately locate.

   It's just that the way of this interference will be exposed.

  Qin Tao nodded: "What about cheating?"

"The method of deception is much more sophisticated. It does not randomly emit a large number of electromagnetic waves with the same frequency as the satellite navigation signal. It only emits false signals, that is to say, it simulates the signal of the satellite navigation system. Because of its The power is higher than the power of the satellite, and the receiver will pick up the signal and think it is correct, so it will go to the wrong place."

   "That is to say, if an enemy targets our building, we can completely transfer its aiming point to other targets?" Zhao Ling became excited.

The possibility that Qin Tao mentioned was like a big stone that weighed on her heart. Now, she finally found hope. In this way, she can let the perpetrators taste the result of being beaten and harm others. Those who will eventually harm themselves!

   "Yes, theoretically, but in practice, this technology is very difficult." Yang Weiguo said.

"Why?"

"Because we need to decipher the encoded information of the other party." Yang Weiguo said: "GPS satellites are divided into two types of signals, among which the civilian signal is not encrypted, and even artificial interference is added to reduce the accuracy. We have a way to imitate this civilian signal, but, Their military signals are encrypted, and we are not yet able to decipher this encrypted signal, and if we cannot decipher it, we will not be able to deceive military devices."

  Zhao Ling nodded.

  The satellite navigation system is high-end. It was developed by the U.S. military after years of research. How could the encrypted information of this thing be easily cracked by a teacher of a technical school? Even a team couldn’t do it.

   "That is to say, we can't use GPS spoofing for the time being?" Qin Tao asked.

   "If it is a signal for military use, it is indeed the case." Yang Weiguo said: "We are still working hard to study, and hope to decipher the signal of the current generation of navigation satellites before the second generation of US navigation satellites is launched into space."

   "The cracking speed can't keep up with their development speed, we still have to work hard." Qin Tao sighed.

   Now, GPS has been networked and has become the most important satellite navigation system in the world. However, this does not mean that you can sit back and relax. Americans are still developing the next generation of navigation satellites.

   It is conceivable that the data encryption of the new generation of navigation satellites will be more stringent. The work of deciphering is quite difficult.

   It would be great if we could implant our own chips into the next-generation satellite navigation system of the United States! However, this wish seems to be just a dream. Chips of this level will definitely not be handed over to SMIC for OEM. of.

   "If we want to prevent the attacker from finding out that the jamming has been done, but still effectively jam the receiver, there is only one way left." Zhao Ling said.
