Chapter 796

The question is, without GPS, how does the UAV of a big country in the East do it?

Inertial navigation?

Come on, this kind of navigation is feasible, but the error is too large. As time goes on, the deviation of inertial navigation measurement value will be greater, so this kind of navigation is OK in the general direction, and accurate calibration is not needed at all.

From the radar display, the UAV of a big country in the East, like an embroidery needle, walked out a precise and safe route track in the area with dense routes, and quickly approached the patrol ship rush in the rear.

If the UAV relies on the inertial navigation with an accuracy error of several hundred meters and kilometers, the UAV may have been in close contact with the aircraft on other routes for a long time, and can it fly so poetically?

Of course, in addition to inertial navigation, there is also ground radio guidance.

For example, the hu-25d has been receiving calls from air traffic controllers in the Yangtze River Delta. In fact, it is a ground guidance of changing direction. The problem is that the hu-25d "Guardian" of the coast guard is not a vegetarian in commanding the patrol aircraft. The airborne electronic equipment has been passively receiving radio signals from the surrounding area, and then using the airborne computer to distinguish and screen them.

Just now, the UAV of a big country in the East was only more than 50 meters away from the patrol plane commanded by hu-25d "Guardian". No electrical signal could escape the eyes of hu-25d.

Through rapid analysis, it can be found that UAV only receives attitude adjustment signal and returns ordinary radio and television signal, but there is no special ground guidance signal for aviation and the guidance signal answered by carrier.

That is to say, the UAV is not equipped with this function at all.

The inertial navigation error is too large, the ground radio navigation is not installed, and the GPS satellite navigation signal is interrupted because of the high probability of failure. In this case, how can the UAV of a big eastern country accurately interpenetrate in the dense route? Is it difficult to have eyes and ears on it?

"I know!"

Cole did not know how long he was in a daze at the screen of the console. Finally, he suddenly realized that it was a cry, which startled Donne beside him. He quickly asked, "what do you know?"

"What kind of navigation device is used by UAVs in a big country in the East."

"What device?"

"A device similar to MK6 autonomous navigation system." Cole's face is a little dignified, but on one side, dawn is confused. MK6 autonomous navigation system, what the hell is this? I haven't heard of it at all.

Fortunately, this time it was no use for dawn to ask, and Cole said it to himself, but it was OK that he didn't listen. As soon as he heard it, dawn was thundered in his heart, and his head was buzzing.

"MK6 autonomous navigation system itself is not well-known, but its application object is world-famous, that is, the core navigation system of militia III intercontinental ballistic missile, which makes the world scared."

As for its development type, it is widely used in many aviation platforms, such as B-52 strategic bombers, B-1B strategic bombers, RC-135 electronic reconnaissance aircraft, C-5 heavy transport aircraft and so on. Its biggest characteristics are light weight and simple structure. The most important thing is that it won't be interfered by any interference, and it won't spill electromagnetic waves, because this set of system is simple Its anchor is the starlight in outer space... "

……

"Starlight?"

Cole made his own judgment after some thinking. However, in the control room of ty-6 UAV in Xiangzhou, Chen Fang and others learned from Zhuang Jianye for the first time that even without GPS signal, ty-6 UAV can still be unaffected. The reason for accurate navigation is that.

In fact, Chen Fang and his party were very complicated when they learned that the GPS signal was faulty and led to the interruption of satellite navigation signal of ty-6 UAV.

I'm worried that ty-6 UAV will have problems and lead to unnecessary losses. At the same time, I'm also worried about this. OK, let's see how you brag and force us to watch.

I can't help it. When Zhuang Jianye introduced ty-6 UAV just now, his words were almost endless. All the five firsts are becoming a mantra. As for the performance, it's even worse to become a fighter of UAV to save the world and abuse alien creatures.

So that a cadre who came with Chen Fang said with a little ridicule: "except for having children, ty-6 UAV seems to be able to do everything."

As a result, Zhuang Jianye said solemnly that what the cadre said was wrong. Ty-6 UAV can really have children.

"We have started to carry out the experiment of installing UAVs under the ty-6 UAV pylon and then flying in the air. We call this multi UAV control technology UAV bee colony technology. Once this technology is put into application, do you want to have a mother give birth to a baby, a series of UAVs will come out and rush to complete the task? So, the bee colony technology is still abstract. What the leader said just now is good. When I go back, I will change it into the daughter mother technology according to the requirements of the leader. "

After listening to Zhuang Jianye's cheeky words, the cadre almost didn't find a way to get in. It was just because Zhuang Jianye was boasting and boasting about heaven. He made a mockery of Zhuang Jianye. He didn't think that Zhuang Jianye not only took it seriously, but also talked about bee colony technology. When the conversation changed, he had to change his name according to the leader's requirements.This is going to kill the old man. If it's really changed to the child mother technique, and it's spread out, what do you think of him? I don't think he's an old rascal who's going to retire soon.

So I can only explain to Zhuang Jianye that he has no other meaning, that is, to make a joke to ease the awkward atmosphere and let Zhuang Jianye not take it seriously.

In addition, Chen Fang and others helped to say good words, which finally made Zhuang Jianye take back his life. But before Chen Fang could let down his heart, the next moment Zhuang Jianye's offer would make Chen Fang's all bad.

RMB 8.86 million, one!

Yes, it's just one UAV, not the UAV of Tengfei group in the past. It's sold by set. A complete set of ground control devices, communication devices and several UAVs constitute a UAV system.

However, ty-6 UAV broke this tradition. An airplane alone costs 8.86 million yuan. If you include a full set of ground control devices and communication devices, it's no more than 10 million yuan.

And there is only one UAV.

As soon as the price came out of Zhuang Jianye's mouth, it almost made Chen Fang and others' old heart break. You should know that the domestic ordinary small transport aircraft is only about 5 million yuan, and the ty-6 is a UAV. It costs 8.86 million yuan. Why don't you rob Zhuang Jianye.

Because of this, people who had a good impression of the ty-6 UAV before did not hesitate to turn black after hearing the price. Just at this time, the GPS signal failed, and the whole Asia Pacific region was abnormal. The satellite navigation signal of the ty-6 UAV was directly interrupted.

So those who turned black because of the high price began to gloat. They even paid 8.86 million yuan for one. How about Zhuang Jianye? Without GPS signal, it depends on what you do. They dare to ask for 8.86 million yuan. Let's deal with the current mess first.

As a result, the ty-6 UAV, which lost the support of satellite navigation, just lost control for a moment. Immediately, the whole plane was as if nothing had happened. It was not only how to fly, but also how to fly. It was even more courageous to go to the coast guard plane and take some close-up high-definition pictures with airborne photography equipment. Then it left with satisfaction.

After some operation, Chen Fang and others were stunned.
