The question is how did the UAVs of a certain large country in the East do it without GPS?

Inertial navigation?

Forget it, although this kind of navigation is feasible, the error is too large, and the deviation of the value measured by inertial navigation will be greater over time, so this kind of navigation is okay in the general direction, and accurate calibration is not used at all.

Judging from the radar display, the UAV of a large country in the East is like an embroidery needle, walking out of an accurate and safe route trajectory in a dense area of routes, and quickly approaching the Rush patrol ship in the rear.

If the drone relies on inertial navigation with an accuracy of several hundred meters and thousands of meters, the drone may have already made close contact with the aircraft on other routes, and can it fly so poetically?

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

For example, the HU-25D has been receiving calls from the air traffic control in the Yangtze River Delta, which is actually a kind of ground guidance that changes direction, and the problem is that the HU-25D "guardian" of the coast guard commands the patrol aircraft is not a vegetarian, and the on-board electronic equipment has been passively receiving radio signals in the surrounding area, and then using the on-board computer to distinguish and screen them.

Just now, the UAV of a large country in the East was only more than 50 meters away from the HU-25D "guardian" command patrol plane, and no electrical signal could escape the eyes of the HU-25D.

After a quick analysis, it can be found that the UAV only receives the attitude adjustment signal and transmits the ordinary radio and television signal, and there is no special ground guidance for aviation and the guidance signal for the carrier aircraft to respond.

In other words, this function is not installed on the drone at all.

The inertial navigation error is too large, the ground radio navigation is not installed, and the GPS satellite navigation is interrupted due to the high probability of failure.

"I see!"

Cole was stunned for a long time at the screen of the console, and finally suddenly screamed, which startled Dawn next to him, and quickly asked, "What do you know?"

"What kind of navigation device is used by the UAV of a large country in the East. ”

"What device?"

"A device similar to the MK6 autonomous navigation system. Cole's face was a little solemn, but Dawn on the side was confused, MK6 autonomous navigation system, what the hell is this?

Fortunately, there was no need for Dawn to ask this time, so Cole said it to himself, but it was okay not to listen, and when he heard it, Dawn's heart was like being bombarded with a muffled thunder, and his head was buzzing.

"The MK6 autonomous navigation system is not well-known in its own right, but it is used in a world-famous application, which is the core navigation system of the Minuteman III. intercontinental ballistic missile, which is feared around the world. ”

Saying that, Cole sighed again, and continued: "As for its development type, it is widely used in B-52 strategic bomber, B-1B strategic bomber, RC-135 electronic reconnaissance aircraft, C-5 heavy transport aircraft and many other aviation platforms, its biggest feature is light weight, simple structure, and the most important thing is that it will not be interfered with in any way, and it will not spill electromagnetic waves, because the anchor of this system is the stellar light ...... outer space."

......

"Starlight?"

Cole thought about it and came up with his own judgment, but in the control room of the TY-6 drone in Xiangzhou, Chen Fang and others learned from Zhuang Jianye for the first time that even if there is no GPS signal, the TY-6 drone can still be unaffected and the reason for accurate navigation.

In fact, when he learned that the GPS signal was faulty, resulting in the interruption of the TY-6 UAV satellite navigation signal, Chen Fang and his party were very complicated.

I am worried that the TY-6 drone will have problems and lead to unnecessary losses, but at the same time, I also hold on to it, and see how you brag about it.

There's no way, it's really that when Zhuang Jianye just introduced the TY-6 drone, what he said was almost endless, and all kinds of five firsts are about to become a mantra, and as for the performance, it is even worse to incarnate as a drone mecha warrior to save the world and abuse alien creatures.

So much so that a certain cadre who came with Chen Fang said with a little ridicule: "In addition to giving birth to children, the TY-6 drone seems to be able to do it." ”

As a result, Zhuang Jianye really said very solemnly that what this cadre said was not right, the TY-6 drone can really give birth to children.

"We have begun to carry out TY-6 UAV pylons under the installation of UAVs, and then fly in the air experiments, we call this multi-UAV control technology called UAV swarm technology, once this technology is put into application, do you want your mother to give birth to a baby, a string of UAVs will be born to scramble to complete the task? ”

The cadre listened to Zhuang Jianye's brazen words, and almost didn't find a crack in the ground to get into, he was just because Zhuang Jianye bragged and blew to the sky, and by ridiculing from the beginning, ironic, which Cheng thought that Zhuang Jianye not only took it seriously, but also talked about the bee colony technology in a matter-of-fact manner, and changed his name according to the requirements of the leadership.

This is going to be an old life, if it is really changed to the technology of the mother and the mother, and it is passed out, what does the big guy think of him, and he doesn't think that he, an old cadre who is about to retire, is an unserious old rook~~~ hooligan.

So he could only explain to Zhuang Jianye that he didn't mean anything else, just to make a joke to ease the embarrassing atmosphere and let Zhuang Jianye not take it seriously.

Coupled with the help of Chen Fang and others to say good things, Zhuang Jianye finally took back his life, but before Chen Fang could put his mind at ease, the next moment Zhuang Jianye's offer made Chen Fang and these people count all of them as bad.

8.86 million RMB, one!

Yes, it's just one, not like Tengfei Group's previous UAVs, which are sold according to sets, with a full set of ground control devices, communication devices and several UAVs to form a set of UAV systems.

However, the TY-6 UAV has broken this tradition, and an aircraft alone costs 8.86 million yuan, and if you count a full set of ground control devices and communication devices, it is exactly 10 million yuan no more.

And there is only one supporting drone.

As soon as this price popped out of Zhuang Jianye's mouth, it almost made the old hearts of Chen Fang and others stop the fire, you must know that the ordinary small transport aircraft in China is only about 5 million yuan, and the TY-6 is a drone that costs 8.86 million yuan, Zhuang Jianye, why don't you grab it.

Because of this, no matter how good the impression of the TY-6 UAV was, after hearing this price, it was not hesitated to turn black, just at this time the GPS signal failure, the entire Asia-Pacific region was abnormal, and the TY-6 UAV satellite navigation signal was directly interrupted.

So those who turned black because the price was too high began to gloat, and they also paid 8.86 million yuan for a plane, looking at Zhuang Jianye, how about it, what do you do if you don't have a GPS signal, you still dare to ask for 8.86 million yuan, let's deal with the current rags first.

As a result, the TY-6 UAV, which lost the support of satellite navigation, was only out of control for a moment, and then the whole plane was as if nothing had happened.

After some operation, Chen Fang and the others were really dumbfounded.
