Chapter 794

At the same time, in the airspace 176 km northeast of the East Zhejiang sea, the patrol plane under the command of hu-25d "Guardian" of the coast guard of a large foreign country also encountered the same problem as ty-6, that is, the GPS signal suddenly abnormal.

However, unlike the complete disappearance of ty-6 satellite navigation signal, the signal on the hu-25d "Guardian" command patrol plane is only weakened.

In popular terms, the GPS navigation accuracy has dropped a lot.

From the original 15 meters to 85 meters, such a big drop is not big for the hu-25d, which relies on satellite navigation. As a commander, Cole quickly contacted the cruiser rush at sea and asked what happened.

In fact, the commander on the rush had already contacted the headquarters by satellite phone without asking Cole, because the GPS signal on the ship was even worse, reaching 200 meters.

Of course, we have to ask what's going on, or we'll have a big game if we bump into people at sea.

It turned out that it wasn't the GPS satellite that was out of order, but the ground monitoring station in Hawaii, which was responsible for GPS timing in the Asia Pacific region, was hit by a typhoon. The timing signal was not sent smoothly, which affected the GPS navigation signal in the Asia Pacific region.

After all, GPS didn't open its satellite navigation service to the world until last month, and its business volume has increased nearly 100 times compared with the simple military service. It's normal for the signal to weaken due to the time service failure caused by force majeure.

Fortunately, the company responsible for the operation of GPS started the standby monitoring stations in Guam and Australia in time, which enabled the GPS signal to continue.

It's just that the accuracy is a little worse. After all, it's a standby station. Before the key hardware facilities can be updated, it's on the shelves, acting as the so-called key man.

The results are predictable.

But this is not something everyone can enjoy, because GPS is clearly free. In fact, GPS has already made money at the source.

In this way, the world's major navigation manufacturers can use GPS authorization to produce chips, receivers and precision navigation devices containing satellite navigation.

It's just that authorization belongs to authorization, but there is a big difference between authorization and authorization. For example, the phone charges of mobile phones are all called phone charges, but the packages in them have a big difference.

GPS is the same, so the satellite navigation devices of various manufacturers are similar, but the authorization levels are different.

Of course, the priority is given to the military or the powerful departments of the country. Their GPS navigation signals are not only of high accuracy, but also can ensure that the navigation signals will not be interrupted at any time.

The second is the top version of GPS navigation package, which is mainly used in aviation giants such as Boeing, McDonnell Douglas and Airbus. Of course, the precision is not as high as that of the military, but the signal can be guaranteed uninterrupted.

The worst is that the navigation accuracy is not high, and it is easy to interrupt the low configuration of the signal in case of emergency.

The ty-6 UAV of Tengfei group uses the worst GPS components. It's not that Tengfei group is reluctant to buy the best. The key is that people don't sell it to you. The reason is that it is the same as the concept of Tengfei group to maintain world peace and promote human development. So what's the use of the weapon grade high-precision GPS components you want? Entry level civil products fully meet your needs.

With the idea that having something is better than nothing, Zhuang Jianye approved the import business with disgust. As a result The ground monitoring station on the other side of Hawaii made a little mistake, and the ty-6 UAV flying in the sky was cut off the GPS signal directly.

It's all stepmother treatment.

In contrast, the hu-25d "Guardian" command patrol aircraft under Cole's command is more pro than his son's. The precision has dropped from 15m to 85m, which seems to be an amazing drop. However, it's hard to say how much impact these two groups of values have on a patrol aircraft refitted from a business aircraft.

You should know that the hu-25d has entered the scope of air traffic control. Even if there is no navigation information, it can land smoothly with ground guidance.

Even if ten thousand steps back, without ATC, hu-25d can't fly to its destination? Naturally, there is no problem. The range of 85 meters is high precision in the world, which is enough to ensure the hu-25d to arrive at the designated landing airport safely.

Because of this, Cole was surprised at the beginning, and then he was very calm about what to do. Even if the rear commander reported the abnormal GPS situation, Cole didn't care. His navigation accuracy was within the safe range. If there was anything to care about, just fly according to the established route.

Compared with the abnormal GPS signal, Cole was more concerned about the news just coming back from the houfang rush. His hu-25d "patrol man" commanded a runaway UAV in the airspace 60 kilometers southwest of the patrol plane and 15000 meters high.

Previously, Kohl wondered how the aps-143b multi-purpose radar equipped with his hu-25d "Guardian" command patrol aircraft, though not the best in performance, is also the best of its kind. How can the electronic deception signal released be discovered by the air traffic control of a big country in the east?Is the electronic level of a big country in the East higher than that of the Soviet Union before its collapse?

It turns out that where is the explosion of electronic technology in a big country in the East, it is obvious that it is an eye inserted in its own head. No wonder the air traffic control of the other side can firmly grasp itself. It turns out that the unmanned reconnaissance plane of the other side has been circling in the air for a long time.

Knowing this, Cole could only shake his head and smile bitterly. Who could have thought that the other side would use the UAV to detect their whereabouts.

Of course, Cole's smile is just a flash, and more of it is a malicious spectator.

Because he learned from the rush in the rear that the reason why the UAV of a big country in the East lost control was probably due to the abnormal GPS signal, which led to the interruption of satellite navigation. Therefore, this shining eye in the high altitude has a great probability of being lost in the vast sea space, and then falling head down into the sea and scrapped.

Cole, of course, is eager to achieve this as soon as possible. He dares to peep on his head. Now, if the GPS signal is a little abnormal, it will show itself. He dares to play cat and mouse games between the sea and the sky, and does not see if he has that ability.

"It's a pity that we've been caught by each other's air traffic controllers. Otherwise, we really want to fly over and see how their UAVs play circles in the sky."

Staring at the strange track of the UAV detected by the airborne radar, Cole put his hands around his chest, and some regret appeared on his proud face.

Dorn, the Huffington Post reporter in the rear, also nodded regretfully: "I'm the same. The sense of falling has a different kind of tragic beauty. If I can record it with the camera, I must be the most favorable competitor for the Pulitzer Prize."

"Yes What a pity okay? What's going on? How did the signal disappear? "

Cole sighed with approval, as if he could win the Pulitzer Prize for news. But just as he was going to continue to talk about this topic, the little black dot on the screen, which was drawing a strange circle, suddenly disappeared. He kept staring at the screen. Cole immediately stopped talking, straightened up, and clattered on the keyboard for a long time, but there was no movement on the screen Quiet.

Then dawn said, "could it be a crash?"

Cole didn't answer immediately, but thought for a while before nodding: "don't rule out this possibility But... "

"Sir, look out of the cabin..." In the middle of Cole's words, the pilot in the cockpit suddenly roared. Cole quickly turned his seat and pulled up the porthole curtain behind him. Then he froze there as if he had been cursed. Outside the cabin, a science fiction UAV with the size of a light fighter plane flew side by side with hu-25d
