Chapter 1378 Jiang Chen's Courage

Seeing that everyone was still a little ignorant, Jiang Chen smiled helplessly and said to everyone: "Let me put it this way, whether it is air combat or ground attack, it is a test of the pilot's reflexes and ability to judge and choose. Among them, the reflex , is to require the pilot to be able to react quickly and handle it properly in a timely manner. Of course, it is the pilot who ultimately operates the drone, but it is not the pilot who drives the drone, but operates it on the ground behind through the ground control equipment. So we also refer to these pilots as drone pilots."

"Of course, after training, their quality can basically reach the level of fighter pilots, so their responsiveness is not bad. But because of the delay in signal propagation, that is to say, when the signal from the drone is transmitted, there is actually no way to respond." It took several seconds for the human-machine side to react, and it took several seconds for the drone to receive the command, so the whole reaction process was a bit long. So there is no need to think about air combat. With such a long delay, the plane has long been shot down by the enemy. And the ground attack is not enough, because with the speed of the drone, after the whole reaction process, the plane has been flying for a long time, and it can How to attack the previously discovered targets."

Everyone nodded when they heard the words, and then began to discuss.Indeed, this is a problem, and it is also a worldwide problem that has restricted the development of drones for a long time. How to solve it, everyone expressed their opinions and debated for a while.

Director Song smiled slightly at this and said to Jiang Chen: "Xiao Jiang, since you can raise this question, it means that you have worked hard on this issue. And if you say it at this time, it means that you must have already responded. solution."

Seeing what Director Song said, everyone turned their attention to Jiang Chen again.Regarding this, Jiang Chen smiled and said: "We have always had a headache about this problem. But we have to bite the bullet and study it, because it can be said to be the key to the success of the entire drone project. But how To solve this problem, we have thought of many ways, and we have debated for a long time like everyone just now. In the end, we are still deciding to solve this problem from two aspects. The first one is radio transmission. We need more Faster, higher rate radio transmission technology.

So from this aspect, we start from the radio transmission technology and study the radio technology or radio equipment that can transmit faster.On the other side, we also start with these signals. To put it bluntly, these data are some digital codes. We need to repackage and simplify these transmission contents to reduce their volume.In this way, its transmission speed will be faster, and after streamlining, the reaction time will be shortened. "

On the other hand, Jiang Chen went on to say: "We have worked hard on this transmission method. After research, we found that during the transmission process, the signal gradually weakens as the distance increases. And because of the arc of the earth, the transmission The distance is very limited. If it exceeds this distance, the signal will become more difficult during the transmission process, the loss will be large, and the delay will be very serious. So we want to change the way so that the data transmission between the two can be It is more direct and rapid, and not affected by weather conditions and terrain factors. After considering these factors, I decided to directly add a media platform to the two for receiving and amplifying, and then transmitting the two between data signals."

"Satellite?" Director Song responded immediately.

Jiang Chen nodded and said: "That's right, it's a satellite. We decided to transmit the information interaction between the drone and the ground control center through satellite communication. For this reason, we have also carried out relevant research and exploration in this area. And successfully launched one of our datacom satellites."

"Hahahaha. Let me tell you, why do you want to launch a satellite? It turns out that you are preparing for this drone. Some people complained to me before, saying that we have communication satellites, why do you still want to launch satellites? Was it burnt with money, now it seems that everything is clear." Director Song laughed loudly.

Hehe, Jiang Chen smiled and said, "We have thought about and experimented with the communication satellites we launched before, but they can't meet our requirements. There is no way, these satellites themselves are relatively backward in technology, so they can't keep up. It’s our rhythm. And it’s mainly because we use digital signals, and now some of our satellites still use analog signals, so they can’t meet the needs. In addition, the bandwidth of satellites is too small, let alone we just use certain frequency, even if all of them are given to us, it is not enough. Another is the power and information processing capabilities. Those satellites have very limited data processing capabilities, and the power is relatively low, which is not in line with our requirements. So After considering so many reasons, we decided to develop a satellite suitable for our use. Fortunately, with the help of so many brothers, we also successfully completed the development of the satellite and successfully launched it.”

"Then it looks like you've put a lot of thought into this project, kid. I'm afraid the two navigation experiment satellites at the beginning of the year were also preparing for this project." Deputy Chief Zhao asked while looking at Jiang Chen.To be honest, he is also really impressed by Jiang Chen's courage now. To be able to make such a big effort for a project, and even launch a satellite specially, this is probably something that others dare not even think about.

Jiang Chen nodded with a smile and said, "There is part of the reason. After all, if we want to fly drones, this satellite navigation is an indispensable technology. And I will also tell everyone about the satellite navigation situation. Passed. It can be said that this technology will greatly promote the development of our country in terms of military, military industry, economics, social construction, and external influence. Even this is a way for our army to win future information wars One of the most important core technologies, and we have lagged behind Laomei for many years, and we can’t go on like this. Otherwise, we will be monopolized and controlled by Laomei in this respect, so we have to catch up But it will be difficult."

"Indeed, the state also attaches great importance to this technology, and we will continue to increase investment in this area in the future. You can rest assured that with the support of the entire country, you can just move forward boldly." Director Song nodded.

"Then Xiao Jiang, since you pulled this drone out of the hangar, why don't you just let us have a look?" Deputy Chief Zhao said impatiently as he looked at the drone.
