The last leader of the world starts with an elite infantry squad!

"Hello, Chief!"

"Hello, Chief!"

...

As soon as Gu Chengyuan got out of the car, he was shocked by the scene in front of the School of Computer Science. Wasn’t he here to inspect the drone company?

Why are there so many ordinary survivors?

"Hello!"

The drone company commander saw Gu Chengyuan's confusion and quickly explained:

"Captain, let me introduce you. These are teachers and students from the School of Computer Science. They have contributed a lot to the construction of our drone control system. When we heard that you were coming, we wanted to meet you!"

Seeing the drone company commander speaking for him, Wang Wenjia gave him a grateful look, and then immediately explained to Gu Chengyuan:

"Hello, Chief, please don't blame Comrade Xiao Zhang for taking the initiative. These are all strong requests from our computer school teachers and students!"

"The soldiers fought bravely on the front lines, and you protected our lives. You also respect talents so much. It was not easy to find an opportunity to thank you in person, and no one wanted to miss it, so I took advantage of my seniority and came here with such a shameless attitude!"

Listening to Wang Wenjia's words, Gu Chengyuan's expression gradually became full of emotion. He gathered his emotions and began to get into the state. He said with a righteous look on his face:

"It is the duty of a soldier to defend his country. The current situation is the result of the joint efforts of the military and civilians. I, Gu, really don't dare to take credit for it!"

"Our army can only protect the present. Only by protecting you can we protect the future of mankind!"

Bang bang bang~~

Pa pa pa pa pa~~~~

......

As soon as the words fell, the whole audience burst into warm applause!

In this situation, some emotional teachers and students already had red eyes, and their eyelids could hardly hold back their tears!

The words "You are the future of mankind" spoken by Gu Chengyuan were extremely destructive to these scientific researchers!

You have to know that since the end of the world, all they have encountered are blows, blows, and more blows. They have been marginalized to the point that they even need connections to use electricity!

Therefore, Gu Chengyuan's words were tantamount to giving them the affirmation they needed most when they were most vulnerable and most self-doubting!

"Commander, with your words, we will die with no regrets!"

When Wang Wenjia said this in a trembling voice, Gu Chengyuan reached out and held the other's dry old hand tightly, shaking it vigorously, conveying his sincere emotions with body language!

"On the road to rebuilding civilization, no one can be left out!"

Hearing this, Wang Wenjia was completely overwhelmed and his heart was broken. Tears streamed down his face for a moment!

Kaka~

As the shutter sounded, Zhou Guihong froze the scene of Gu Chengyuan and Wang Wenjia holding hands for eternity. In addition to the two of them, the background composition also included a group of teachers and students with tears in their eyes, and the light of faith shone on everyone's face.

...

"Commander, please look, this is the data link center we just built!"

Surrounded by the crowd, Gu Chengyuan walked in the clean white passage and soon arrived at the end of the corridor on the first floor of the School of Computer Science.

I walked into a huge computer room, filled with box-like cabinets, various cables connecting each other, and colorful indicator lights flashing, as if they were breathing.

Huhuhu~

Listening to the sound of the fan in the computer room, Gu Chengyuan couldn't help but show curiosity. It was the first time he saw the legendary data link center.

Whether listening or watching, you can feel the full sense of technology.

He once thought that drones were controlled by someone with a remote control, like toy remote-controlled airplanes, but with longer range and more functions. However, he did not expect that in addition to the control center, there was also a data link center.

Seeing Gu Chengyuan's curiosity, the drone company commander immediately introduced:

"Report to the commander, the full name of this data link is: Data Link High-Tech Battlefield Nervous System Control. Our military drones are controlled via data links!"

"Generally, there are three common data links: tactical-level data links, weapon-level data links, and intelligence-level data links."

"For example, the mid-course guidance used by fighter jets and warships to launch air-to-air missiles is a weapon-level data link that can not only perform real-time adjustments to the guidance target, but also receive real-time images sent back by the guidance target."

"The disadvantage of weapon-grade data links is that they are not very versatile and have a relatively small range, normally within a few dozen kilometers. We are considered the world's top in this regard, but our range is only over a hundred kilometers."

"Intelligence-level data link is a means for early warning aircraft and fighter jets to exchange data. It is also called a public data link. The effective range does not exceed 500 kilometers. Sometimes it is mentioned that aircraft perform battlefield signal relay tasks, which is actually equivalent to mobile WiFi. This method cannot achieve ultra-long-range control of drones."

"For example, the United States places drone control stations in the country and can use drones to attack fellow countrymen. It uses the satellite communication frequency band plus inertial navigation configuration."

"Does that mean the maximum mission range of our Falcon 7 drone is within 500 kilometers?"

Gu Chengyuan has seen the data of the Falcon 7 UAV. Its cruising speed is between 150 and 180 km/h, and its maximum flight time is more than 40 hours.

Therefore, even at the minimum cruising speed of 150km/h, the round trip flight radius of the drone should be around 3000km, which is why Gu Chengyuan asked this question.

"Report to the commander, theoretically yes, but in reality, in a complex electromagnetic environment, it is impossible to reach the full value, which means that the maximum cruising range of our drone is only more than 400 kilometers."

So that's how it is. Upon hearing this, Gu Chengyuan nodded slightly.

However, this range of 400 kilometers is enough and can basically cover the current sphere of influence.

You should know that the Chongyi gathering place, which is the farthest away, is about this number in a straight line.

“Is this drone easily interfered with?”

Every time I saw some drone videos before the end of the world, there would always be people in the comment section saying that the drones would be useless if there was electromagnetic interference, as if military drones had a serious flaw. So Gu Chengyuan took this opportunity to ask the questions in his mind.

"Commander, military drones are almost impossible to interfere with!"

Obviously, the drone company commander is very confident about whether the drones will be interfered with.

"Reporting to the commander, the drone data link uses electromagnetic frequency band hopping technology. The frequency band it receives the signal jumps repeatedly and very quickly. It may jump from 0.001 Hz to 133 Hz in 188 seconds, and then jump from 0.001 Hz to 188 Hz in 83 seconds."

"The speed has a regular pattern, and the jump time can form a code. Only by knowing his code and which time period he jumps on which frequency band, can we interfere with it!"

"So it is almost impossible to interfere with military drones unless the entire data link is interfered with, and the data link center is usually deployed in the mainland or on an aircraft carrier."

"For example, right now, our data link center is located in the computer school of the gathering place. If the enemy wants to interfere with our military drones, they must first interfere with the entire gathering place! There is no way to directly target the drones performing missions above their heads with interference methods!"

After listening to the introduction of the drone company commander, Gu Chengyuan suddenly understood.

If drones are really so easy to deal with, how could they become a trend in the development of world military equipment?

I guess many people have seen too many drones shooting down civilian drones, which gives them the illusion that military drones are easy to deal with.

Afterwards, Gu Chengyuan left the data link center and came to the drone control room. As soon as they saw Gu Chengyuan enter, the soldiers in the operating room stood up one after another.

"Hello, Chief!!"

"Hello, Chief!"

...

"You guys keep going, I'll just watch!"

"Yes!"

After the drone crew members sat down, Gu Chengyuan also stepped into the drone control room with a curious look on his face.

There are many large screens in the drone control room, each of which displays a different perspective. Every drone operator wears special equipment on his head and holds a joystick similar to a fighter jet's joystick in his hand.

"Reporting to the commander, this is the control room of the first unit of our drone company."

"A crew jointly controls a drone. Some are responsible for controlling the drone's flight attitude, some are responsible for handling the air situation, some are responsible for intelligence collection, and so on."

"We are about to carry out our first reconnaissance mission. If you are not busy, I hope you can take a look at how the soldiers are carrying out their mission!"

"can!"

Gu Chengyuan did not refuse this. He also wanted to see whether operating a military drone was like playing games!

Also, it's a bit late
