Chapter 282

Langdon and Mike are confused. Miracle? What miracle? Shouldn't the particle company be the first to test? Why did Colonel Moore get into the operation shelter of H company?

Until the UAV on the runway starts to glide, then accelerates, and then leaps into the air. If they don't know that the UAV is the latest product of H company, they will be killed.

"Mike, you tell me, why don't they use discovery? Tell me Langdon pulled Mike by the collar and growled.

Mike spilled all his coffee in his hand, but he can't care about it now, because at the moment, he also wants to know how H company can make a new UAV different from Discovery series.

I can't help it. If it's not clear, once H company's products crush particle company's "God of competition", it's equivalent to swindling General Motors with false business intelligence. At that time, don't say that the two million dollars he has won will be wasted, and all the wealth he has accumulated for half his life may be put into it.

as like as two peas, he said, "how can Landon get angry and not explain how Mike explained it?" he said that the Moore colonel in the operating room, sitting on the operation position, was holding the same manipulating pole as the plane, and looked at the flying posture and data displayed on the screen in front of him, and was excited like a child.

In particular, on a nearby screen, the "eagle eye" 2 integrated view detection system improved by the Apache armed helicopter integrated photoelectric system uploaded real-time images, which were even more startled.

It's not about how real the real-time picture is, it's about how clear and fluent it is. It's not about watching the live broadcast, but it's not that bad.

"How did you do that?"

When the bullet drone entered level flight, Colonel Moore pointed to the screen in the middle and asked Lister.

"Within 200 kilometers, the C-band data link is used, that is, the top management of major companies often use videoconference terminals. A short-distance data transmission system is to convert various data signals on the aircraft into analog signals, which are sent back to the ground control station, and then the ground control station controls them according to the signals, with a delay of about 10 to 20 seconds."

Smell speech Moore nodded, the middle screen is really a card, but it is much better than the real-time transmission image of Discovery-1 UAV he saw in the Ministry of justice, where is not the card, but the pause, because the highest delay there is up to two minutes.

Obviously, H company has made improvements in its communication system. Moore nodded with satisfaction. But the next moment he remembered that general James had just flown more than 300 kilometers to control the UAV, and he could land at the base accurately. This distance has already exceeded the scope of the C-band data link, so he continued to ask, "how does general James achieve long-distance flight?"

"Satellite!" Liszt's answer was straightforward.

"Satellite?" Moore frowned suspiciously.

"Yes, Colonel, we use satellites." As he said this, Liszt pointed to the side: "in the shelter of the car next to him is the terminal of the whole set of" spirit of Troy "satellite communication system, which uses the army's" spirit of Troy "communication satellite to relay the communication of our bullet UAV, so as to complete the two-way transmission of flight attitude and reconnaissance data.

Of course, there are only four "spirit of Troy" communication satellites in the army. There are not only some blind spots, but also insufficient communication channels in the army. At this time, our bullet UAV will use the high-frequency data communication channels of commercial communication satellites. In other words, as long as the communication satellites in the sky are still in normal operation, our bullet UAV will swim in the sky It is not bound by the traditional communication distance

With this remark, many base officers, including Moore, were surprised. They never thought that communication satellite technology could be applied to UAVs, which would make UAVs become free birds flying in the sky.

We should know that the reason why UAVs are not widely used in various countries is not that UAVs are not good, nor that countries are not clear about the bright future of UAVs, but that under the existing conditions, the limitation of communication distance makes the operating distance of UAVs very embarrassing.

Take the United States as an example. Even if the most powerful ground control station is used, it can only control a distance of 500 kilometers at most. It can not be affected by signal failure, earth curvature and other aspects. This distance is already the limit.

In order to control the UAV to fly further, it is necessary to set up multiple ground stations to carry out relay control similar to space TT & C.

In this way, the use of UAVs is too high, because such a ground station can become a satellite ground receiving station after a little transformation, and the satellite can carry out 24-hour continuous reconnaissance. Why not use a more efficient satellite?

What? What if the satellite can't see clearly?

So many people fly reconnaissance planes, and they don't have to rust? As for drones Let's save it for short-range tactical reconnaissance.

But now, H company not only uses military communication satellites to solve the problem of secure communication, but also creatively integrates commercial communication satellites. This means that long-distance UAV control completely gets rid of the shackles of ground control station, and puts it from the ground to space. It not only gets rid of the problem of long-distance UAV control, but also greatly reduces the cost To a very low level.Because whether it is military or commercial, the service charge of communication satellite is much cheaper than that of ground station.

As for the technical feasibility of this mode, Moore and others don't even think about it. Military communication satellites don't mention it. Even commercial communication satellites have very good communication transmission effect. Among other things, American TV programs can be watched all over the world, but they don't rely on communication satellites in the sky.

Even the TV signal can be accepted and sent, and the flight data, reconnaissance pictures and even simple fact images much smaller than the signal can not be transmitted?

In a word, the officers of the Advanced Research Program Office of the Ministry of defense are very aware of the value of this long-distance control system, because H company is not only a simple innovation, but also really opens a new era of UAV.

"Captain Carlos, write this important performance into the test report. Remember to write it in detail. I believe the generals of the air force will be very interested in it." Colonel Moore, who was still operating the bullet drone, gave orders to an officer with a folder behind him.

The captain, Carlos, nodded: "yes, sir." I immediately picked up the folder and began to write on it.

Moore turned back and focused on the operation of the bullet drone again. Just as he was holding the joystick and preparing to circle around the hill, a string of red characters flashed out on the screen in front of him: "target, attack!"

Moore surprised, quickly asked Liszt: "your UAV really can use weapons?"
