Before setting off from Xingcheng yesterday, Xu Ziling had greeted the "Liaoning", saying that it would be tested in other places today, and that they would need their cooperation at that time.

After receiving the task of assistance, several radar soldiers have been staying in the radar room, keeping their eyes on the radar system, for fear that they will miss it.

Like ordinary visual dialogue, the visual communication of the "Eagle Eye System" is no different, it is nothing more than that the person on the screen can show the other party, and it is necessary to find out the difference, that is, the "Eagle Eye System" uses scanning imaging, which is a little clearer than the video image head.

However, this difference is not what everyone pays attention to, what they value is that the submarine is at a depth of 500 years underwater, does not release the communication antenna, and does not float but can smoothly achieve communication with the ground unit.

"You really can!"

Until Xu Ziling interrupted the communication, Captain Li still looked shocked, muttering to himself alone.

And the others, not much better than him, that is, Professor Xie and them, even if the system is from their own hands, they are quite surprised to see the results of the underwater test for the first time.

Xu Ziling saw everyone's reactions, smiled in his heart, and said in his heart: If there was no such function, I would not have made a big deal about this project.

Next up was tested for one of the most important features of a submarine: navigation!

The navigation system of submarines is much more complex than that of ships at sea, including astronomical navigation systems, radar navigation systems, satellite navigation systems, short-range and long-range radio navigation systems, inertial navigation systems and integrated navigation systems, while only inertial navigation and integrated navigation can be used in stealth.

Therefore, when the submarine is sailing, it is quite troublesome to confirm whether the course is correct.

At the beginning, considering that the microwave signal of the "Eagle Eye" can easily penetrate the water quality and only has a small loss that can be counted, Xu Ziling considered that this feature can be used for navigation.

The system is opened, because there is no information about the submarine topographic map in the system, the navigation interface is just a map marked with detailed latitude and longitude, and after a short connection with the satellite, a green dot is displayed on the map.

"Since there is no submarine topographic map in the database, for the time being, it can only display this kind of electronic map with only latitude and longitude, and this green dot represents our submarine, and the system will be perfected in the future, and the ships and submarines of the entire ocean will be in the same system network, if there are other ships and submarines nearby, this will be displayed on it." Xu Ziling pointed to the map displayed on the screen and explained, "As for the submarine topographic map, it must not be able to be collected at once now, and it is not possible to collect it by running around the world by a ship, and it is still during the testing period, and it will not be put into practical use for the time being. As for the complete map, I'll want to collect it all then,"

The entire earth, the sea area occupies three-quarters, you can imagine how wide a place, now the small "Eagle Eye" mounted on the ship scanning distance is only 700 kilometers radius, and the long-distance Eagle Eye is too expensive, not suitable for large-scale equipment, so it is a little unrealistic to rely on ships or submarines to sail in the sea to collect the seabed topographic map of the entire sea area.

Because in the ship that wants to sail at sea for a long time, then his tonnage must not be small, and the tonnage is not small, then from one side to limit his speed, according to statistics, the earth's sea area is nearly 400 million square kilometers, even if it is calculated at a speed of 30 knots, it can only scan a diameter of 1,400 kilometers at a time, it is conceivable that this ship needs to run non-stop on the ocean for many years to be able to collect the entire map, so this method is definitely not advisable.

As for waiting for all the ships and submarines to be equipped with "Hawkeye", it will be a few years later, so this is unlikely.

The matter of the map, Xu Ziling has already considered, these methods have been vetoed by him, his idea is to use the reconnaissance plane or wait for the "Space Hawkeye" to be successfully launched, to get it at one time, but thinking that the reconnaissance plane will also take a long time, he still thinks that it is best to get the "Hawkeye" after it is arranged, anyway, he is not in a hurry at this time, so he said to everyone to wait for him to find a way to solve it in the future.

Compared with submarine communication, submarine navigation undoubtedly makes people feel more real and shocking, especially when the "Eagle Eye" collected a submarine topographic map within a range of 1,000 kilometers, Xu Ziling signaled the submarine to start and set it to automatic navigation, and when the navigation system automatically reported all navigation data in the sea area at a depth of several hundred meters, everyone was dumbfounded.

"The main thing is the limitation of submarines, in my imagination, submarines can be fully automated, just like airplanes, as long as the automatic cruise is set, it can be autopiloted, not just like now, just report some data to be satisfied."

Looking at the excited crowd, Xu Ziling smacked his lips and said the submarine he had in mind.

"It shouldn't be easy to add an autopilot module to a submarine." Listening to his words, Professor Xie turned sideways to Xu Ziling and said, "Although I don't understand this business, I also know that submarines can sail automatically from different planes and ships, and that is mainly because of the problem of underwater, but now with this kind of navigation technology, it is indeed possible to develop in this direction." ”

"It's not too hard, I have some ideas." There are some problems, Xu Ziling doesn't mind being known by others, "Automatic operation is just an inevitable trend, and I am also considering developing large unmanned submarines on this basis." ”

"Ah......h

The two of them discussed the issue of technology in such a serious way, but it made Captain Li and some people dumbfounded, in their opinion, the submarine that can initially have automatic navigation is already the world's leading technology, and they actually want to make a submarine with automatic cruise, so will many people in the submarine not need it in the future? Three or two people can operate a submarine?

"This is just a plan, even if you start relevant research now, it will not be able to come up in three or five months." Hearing Captain Li's surprised voice, Xu Ziling turned his head to look at him and said with a smile.

Whether it is in the optimization scheme of the "Seawolf-class" submarine or the "653" submarine, there is a fully automated control scheme, and Xu Ziling was thinking that fully automated driving is the development trend of submarines in the future.

However, the optimization scheme is based on the overall optimization of the original submarine, and the communication, positioning and other aspects have been optimized, but the satellites and ground equipment that can be matched can play a role, but these are not things that are in the optimization scheme, so many schemes cannot be made now.

Now with the emergence of "Space Hawkeye", it can be said that it has completely made up for the gap in this aspect, so Xu Ziling was resolute in his heart about this idea, considering that the Jiangnan Plant will carry out research on submarine automation after the completion of the warship project.

In his opinion, the submarine is so big, the fighter is relatively so much smaller than it, and it has achieved automatic cruise, and there is no reason why the submarine cannot succeed, as Professor Xie said, the automatic driving of large submarines was not considered before, that is because it needs to navigate underwater, even if the submarine can navigate automatically, it will not be used, and now the "Eagle Eye" has solved this problem, and it is completely necessary to invest in the study of automation problems, and it should not be a difficult thing.

Of course, what he values most is large unmanned submarines.

Unlike airplanes, submarines face a more complex deep-sea environment, and pilots have the opportunity to parachute out in a plane crash, while the crew can only wait for rescue before they run out of oxygen in the boat. In this sense, unmanned submarines may play a greater role than unmanned aircraft on the battlefield in the future, and it is also from this aspect that Xu Ziling has made up his mind to start studying the unmanned use of large submarines.

Unmanned submarines, as early as a few decades ago, there was a country to develop, but due to the constraints of underwater communications and other reasons, even after decades of development, in this area has not been much developed, the existing submarines, the main application field is still in the civilian aspect: from salvage to rescue, seabed exploration; On the military side, it is used for anti-mine warfare and as a network node in wartime.

The existing unmanned submarines are controlled by remote control, because it is very complicated and difficult for unmanned submarines to communicate with the outside world, and they must also achieve a balance between secrecy and transmission efficiency. Therefore, there is only one slightly more mature way of remote control: transmitting signals through cables. However, this method has a huge drawback, that is, the maneuver range of unmanned submarines will be limited.

When a submarine wants to operate, it definitely needs a release platform, or a ship, or an aircraft carrier, but you can't always drag a cable thousands or tens of thousands of meters long to control the submarine, right? Therefore, using this remote control method, in the long run, is not a desirable way at all, the war starts, the distance of more than 1,000 meters, there is no meaning at all, it can only be used to clean up mines in the absence of emergency.

The microwave signal of the "Eagle Eye" completely solves the problem of difficult communication, so if the submarine wants to develop to the unmanned aspect, it can use wireless communication technology and new communication methods, which fundamentally break through the original limitations, and in this way, it is possible to completely abandon the cable control mode with too obvious drawbacks.

As for the miniaturized unmanned submarine, Xu Ziling believes that in the military, except for the use of suicide attacks, there is not much use, so he set his sights on large unmanned submarines.
