At the same time, in the airspace 176 kilometers northeast of the coast of eastern Zhejiang, the HU-25D "guardian" command and patrol plane belonging to the coast guard of a large foreign country also encountered the same problem as the TY-6, that is, the GPS signal was suddenly abnormal.

?? However, unlike the TY-6 satellite navigation signal that completely disappeared, the signal on the HU-25D "Guardian" command patrol aircraft only weakened.

?? In layman's terms, the navigation accuracy of GPS has dropped a lot all at once.

?? From the original 15 meters to 85 meters, such a large drop is not small for the HU-25D, which relies on satellite navigation, so Cole, as the commander, hurriedly contacted the patrol ship Rush that was sailing at sea and asked what was going on.

?? In fact, without Cole asking, the commander of the Rush had already used a satellite phone to contact the headquarters, because the GPS signal on their ship dropped even more outrageously, reaching 200 meters.

?? Of course, you have to ask what's going on, otherwise it's a big game to bump into someone at sea.

?? It turned out that it was not the GPS satellite that had a problem, but the ground monitoring station in Hawaii that was responsible for the GPS timing in the Asia-Pacific region was hit by a typhoon, and the timing signal was not sent smoothly, resulting in the GPS navigation signal in the Asia-Pacific region being affected.

This is also a helpless thing, after all, GPS did not open satellite navigation services to the world until last month, and the business volume has surged nearly 100 times compared with simple military services.

Fortunately, the company responsible for operating the GPS activated the backup monitoring stations in Guam and Australia in time, so that the GPS signal could be continued.

It's just that the accuracy is a little worse, after all, it is a backup station, and the key hardware facilities have not had time to be updated, so they have rushed ducks to the shelves, acting as the so-called key Mr.

The results can be imagined.

But that's it, not everyone can enjoy it, because GPS is clearly said to be free, in fact, GPS has already earned 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 the authorization is authorized, but there is a big difference between the authorization and the authorization, just like the phone bill of the mobile phone, which is called the phone bill, but the package inside has a big saying.

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

The top priority, of course, is the military or the country's powerful departments, whose GPS navigation signals are not only highly accurate, but also can ensure that the navigation signals are not interrupted at any time.

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

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

Tengfei Group's TY-6 UAV uses the worst GPS components, not that Tengfei Group is reluctant to spend money to buy the best, the key is that people don't sell it to you, the reason is the same as Tengfei Group's philosophy, to maintain world peace and promote human development, so what is the use of your Tengfei Group's weapon-level high-precision GPS components? Entry-level civilian products fully meet any of your needs.

With the heart that something is better than nothing, Zhuang Jianye endured the disgust and approved the import business, and the result was ...... The ground monitoring station in Hawaii was a little out of order, and the TY-6 drone flying in the sky was directly cut off from the GPS signal.

It's completely the treatment of a stepmother.

In contrast, the HU-25D "guardian" commanded by Cole is really closer than his own son, and the accuracy has dropped from 15 meters to 85 meters, which seems to be an astonishing drop, but it is really impossible to say how much impact these two sets of values have on a patrol aircraft modified from a business jet.

You must know that the HU-25D has entered the air traffic control range, even if there is no navigation information, it can also land smoothly by relying on ground guidance.

Even if you take 10,000 steps back, without air traffic control, the HU-25D will not be able to fly to the destination? Naturally, there is no problem, and the range of 85 meters is already considered high-precision in the world, which is enough to ensure the safe arrival of the HU-25D at the designated landing airport.

Because of this, in addition to being surprised at first, Cole was very calm about what to do, even if the rear commander reported the GPS anomaly, Cole didn't care, his navigation accuracy was within a safe range, what to care about, just fly according to the established route.

Compared with the abnormal GPS signal, Cole is more concerned about the news that has just been transmitted back from the rear Rush, and there is actually a runaway drone in the airspace 60 kilometers southwest of the HU-25D "patrol man" command patrol aircraft under his command and at an altitude of 15,000 meters.

Previously, Cole wondered how the APS-143B multi-purpose radar equipped with his HU-25D "Guardian" command and patrol aircraft was not the best, but it was also the top of its class.

Could it be that the electronic level of a certain large country in the East has surpassed that of the Soviet Union before its collapse?

As a result, it was found that where was the explosion of electronic level technology in a certain large country in the East, it was clearly an eye stuck in one's head, so it is no wonder that the other side's air traffic control was able to firmly grasp itself, and it turned out that other people's unmanned reconnaissance planes had long been circling back and forth in the high altitude.

Knowing this, Cole could only shake his head and smile bitterly, who would have thought that the other party would use drones to reconnoiter their whereabouts.

Of course, Cole's hindsight and bitter smile were only for a moment, and more of a malicious look.

Because he learned from the Rush in the rear that the reason why the drone of a large country in the east was out of control was probably because of the abnormal GPS signal, which led to the interruption of satellite navigation, so this shining eye in the sky has a high probability that it will get lost in the vast sea space, and then fall head-on.

In this regard, of course, Cole would like to realize it sooner, and he actually dared to steal ~~ peep on the top of his head, now it's okay, the GPS signal is slightly abnormal, and he dares to play cat and mouse games between the sea and the air, and he doesn't see if he has the ability.

"It's a pity that we have been caught by the other party's air traffic control, otherwise we would really like to fly over and see how their drone is circling in the sky. ”

Staring at the strange trajectory of the drone detected by the on-board radar, Cole folded his hands in front of his chest, and a little regret appeared on his proud face.

Huffington Post reporter Dawn in the back of the side also nodded regretfully: "I am the same, that kind of floating fall has a different kind of tragic beauty, if it can be recorded with the camera, it must be the most favorable contender for the Pulitzer Prize for journalism." ”

"Yes...... It's a pity...... Well, what's going on? Why did the signal disappear?"

Cole sighed approvingly, as if he could win the Pulitzer Prize for journalism, but just as he was about to continue the conversation on this topic, the small black dot on the screen that was drawing strange circles suddenly disappeared, and Cole, who had been staring at the screen, immediately stopped talking, straightened up, and crackled on the keyboard for a while, but did not see any movement on the screen.

At this time, Dawn spoke: "Could it be a crash?"

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

"Sir, look, it's ...... outside the cabin" As Cole was halfway through his words, the pilot in the cab suddenly roared, Cole hurriedly turned the seat, pulled up the porthole curtains behind him, and then froze there as if under a spell, only to see a sci-fi drone outside the cabin, the size of a light fighter jet, just like that, flying on one side of the HU-25D......????
