Chapter 630: Grab with both hands, both hands are hard

The chief engineer of the Defense Work Committee had obviously done some research on this. He frowned and said, "Comrade Zhendong, are you talking about radio triangulation? And then putting it in the sky?"

This is a principle that anyone who has worked with radio or radar knows. Two large transmitters transmit radio signals. The large transmitters have sufficient power and can transmit very far. A small receiver receives the signals from the two transmitters and uses the signals to calculate the distance between itself and the two transmitters. In this way, it can know its exact location.

However, the principle is the principle, and it is still difficult to realize it under the current technical conditions.

There is nothing to worry about when placing these two transmitting pads on the ground, such as location, power, working conditions, etc. However, obstruction by terrain and objects is a big problem.

Especially in mountainous areas and hills, even if you put it on the top of a mountain, it is basically meaningless. Not to mention that you can't receive the signal. Even if you can receive the signal, the strong multipath interference is difficult to solve.

Multipath interference is a special interference caused by radio signals being reflected multiple times in a rugged and complex space, with the same signal reaching the receiver along different reflection paths.

Especially since this thing is used for positioning, multipath interference is a natural nemesis.

So if it can't be placed on the ground, then it can only be placed in the sky. This is also what the chief engineer of the Defense Work Committee thought of after hearing Gao Zhendong's words.

But, let’s not talk about this for now. Is there any airplane that can carry things for a long time? Even if there is, an airplane is like a bird that cannot stop, and it keeps running around.

It is equivalent to the positioning base station in the sky not knowing where it is. Even if the positioning device at the front end knows the position relationship between itself and the two aircraft, it is still useless.

This is why the chief engineer of the Defense Work Committee frowned. The positioning chain was broken here and it seemed unreliable.

Gao Zhendong nodded and shook his head: "This is the last resort. I think that two planes are wasted. One will do."

"Single-station positioning? Is this possible?" This was beyond everyone's imagination. In Gao Zhendong's previous life, although the Citigroup had developed the first generation of a similar system around 55, we didn't get it from Gaul until the 80s. We must admit that in those short ten years, Gaul really brought us a lot of good stuff.

"It is feasible in principle, and I have also evaluated the technology. It should be feasible. The details cannot be explained in a short time, so I will not discuss them here. Assuming that the single-station positioning technology is feasible, let me tell you my thoughts." Gao Zhendong picked up the chalk again.

He first drew a house on the ground and stretched out a three-petal antenna: "We put a fixed base station on the ground to locate the aerial tactical units. In this way, the problem of aerial positioning is solved."

He drew another plane in the sky: "Based on this, we put a set of miniaturized single-station positioning equipment on a large enough plane, such as the one the Air Force is working on..."

What the Air Force is working on is, of course, the early warning aircraft. Radar researchers who have obtained ground clutter processing technology and comrades from the Air Force are tinkering with installing radars on those Tu-4s.

The mission of those Tu-4Ts has been gloriously completed and they are now facing a new mission.

The leaders of the National Defense Committee knew about it, and the leaders of the Army had also heard about it.

Gao Zhendong finally drew a small stick figure on the farthest ground: "This is a small positioning terminal at the front end. It can be integrated with the digital walkie-talkie mentioned earlier. If it can't be made that small, at least it can be integrated into a backpack radio. In this way, a chain is formed. The ground locates the aircraft, and the aircraft locates the ground troops in complex terrain."

The Army's eyes were burning with excitement as they stared at Gao Zhendong: "Interesting, interesting. If this can really be realized, without the second half, just the first half, the Air Force will be so happy that they will jump for joy!"

The question of where the planes went has been harassing the Air Force for a long time. There are positioning facilities on modern aircraft, but they are not very reliable or easy to use.

As for the range of 200 kilometers mentioned by Gao Zhendong, he did not take it too seriously. He also had some common sense. If the ground station increased its power, it should be able to expand it a lot, which would definitely be enough for the Air Force.

The chief engineer of the Defense Work Committee thought about it in more detail: "Well, the first half is fine, but the plane is moving, and the speed is not slow. It takes time to calculate its own position. This chain will still cause a relatively large error when the final positioning device calculates its own position, right?"

Gao Zhendong nodded: "Of course there will be, but it can be used. First, the speed of electromagnetic waves is much faster than that of aircraft. In the time from sending to the completion of the solution, the aircraft can't fly very far, a few hundred meters at most. Secondly, in addition to the position of the aircraft, the aircraft's real-time flight speed and direction can also be sandwiched in the positioning signal for transmission. The positioning terminal on the ground uses these data, combined with the positioning signal, to calculate its own position more accurately."

Although we don’t know much about these technologies, Gao Zhendong explained them in a relatively easy-to-understand way, so everyone can roughly understand what Gao Zhendong meant. It seems that this thing can work!

The soldiers who were still in the meeting hall listened with longing on their faces.

"Squad leader, this comrade is amazing! He is great at fighting and doing science!"

"Are you kidding me? Can anyone who can hold a meeting here be an ordinary person?"

"I hope I can be like him after I retire." "Then you have to work hard and study harder in your academic subjects."

"You don't have to be like him, as long as you have the same work attitude and thinking style as him."

"Yes, yes, yes, there is no high or low in revolution."

"..."

The leader of the Defense Work Committee said to Gao Zhendong with a smile: "Zhendong, you have been thinking about these things for a long time, right?"

Judging from the step-by-step guidance he has provided since he started to work on the project, he must have made arrangements in advance and thought about it for a long time.

Gao Zhendong smiled and said, "Yes, leader, I have indeed thought about this for a long time. Now that the conditions are gradually maturing, we can push forward with it."

The army leader smiled and said, "Zhendong, I see that you are making every effort to make our army as strong as an iron barrel. In addition to the fact that you were born here, is there any other reason?"

Gao Zhendong smiled and said, "Leader, you are right. In addition to the feelings for the old unit, there are indeed some strategic and tactical reasons. This is what I think..."

In the eyes of the leaders, Gao Zhendong's purpose is clear and his thinking is well-organized. His goal is to build the army into a hedgehog that can basically complete all tasks on its own!

Even though the current navy and air force have technological advantages in some projects, the scale of their costs means that the technological advantages cannot be converted into decisive victory. It's too damn expensive!
In Gao Zhendong's expectation, the mission of the navy and air force is to rely on local technical advantages to prevent the enemy from entering the battlefield, send the army to the designated combat area, and block the enemy outside the core combat area. On this basis, it would be even better if some support could be provided to the land.

The army has always been our strong point. We are the best light infantry in the world, and that is not an exaggeration. This title was earned bit by bit with our will and blood despite being completely technically disadvantaged.

Gao Zhendong wanted to arm the army with technology based on the existing will!

Grasp both willpower and technology with both hands and make both hands strong!
In this way, who in the world can stop us?
Under conditions where both air forces find it difficult to enter the battlefield or cannot gain a decisive advantage, the army solves as many problems as possible on its own.

Why in the past we were able to achieve the best of our conditions in terms of both tube artillery and rocket launchers? The reason is that the army actually never counted on air support and was still committed to solving problems on its own.

After listening to Gao Zhendong's words, several leaders nodded, especially the army's side, who felt that Gao Zhendong's words touched the heart.

No need for air support! Just stop the enemy in the air, and we'll handle the rest ourselves!

Air Force: Then should we continue to convert bombers into attack aircraft?

"Well, your idea is good! Indeed, judging from the current technical and economic capabilities, we can only use the army to solve the problem. Thank you for everything you have done for the old army."

Air Force: Tsk, you talk as if we weren’t given the chance to do that.

Navy: Yes, yes, you are right.

The leader of the Defense Work Committee laughed and said, "He's not just doing this for you, hahaha. By the way, Zhendong, you mentioned communications and positioning, what about mobility?"

Gao Zhendong just said three words: "Helicopter!"

Helicopter? This special aircraft is indeed useful, but why did Gao Zhendong only say these three words when it comes to mobility?

"Well, what you said makes sense. It is necessary to equip the border defense forces with helicopters to improve their mobility in dealing with emergencies. By the way, it was you who proposed the search and rescue and armed versions of the Vertical-5. Is it for this purpose?"

Gao Zhendong smiled and said, "The search and rescue type is mainly for rescue, and it has little to do with the mobility of the army. The armed type is really for this. My idea is, can we concentrate some helicopters and set up several small-scale troops, using helicopters as the main means of transportation and support? For vertical strikes, the infantry is only responsible for getting off the aircraft and fighting after arriving at the combat site. In this way, the mobility can be improved to the extreme, and it should be able to have a good effect in certain environments, such as mountainous areas and jungles."

He gave an example: "For example, in this battle, the enemy was obviously deliberately provoking. If the enemy was larger, our exchange ratio might not be so good. However, with the original troop configuration, we couldn't quickly support our comrades. If there was an air assault force like this, it would be meaningful to control and support all outposts within hundreds of kilometers around it."
