Before setting off from Star City yesterday, Xu Ziling had greeted the "Liaoning", saying that today he would test in another place and that they would need their cooperation at that time. He didn't specifically say what they would cooperate with. People also know, because this system has only a few functions, and the only thing that needs their cooperation is communication.

After receiving the task of assisting, several radar soldiers kept guard in the radar room, keeping their eyes on the radar system, for fear of missing it.

Like ordinary visual dialogue, the visual communication of the "Eagle Eye System" is not different. It is nothing more than the person who can display the other party on the screen. If you want to find out something different, that is the "Eagle Eye System" Scanning imaging is a little clearer than video camera imaging.

However, this difference is not what everyone pays attention to. What they value is that the submarine can successfully communicate with the ground unit without releasing the communication antenna or floating up at a depth of 500 underwater.

"Really!"

Until Xu Ziling interrupted the communication, Captain Li still looked shocked and muttered to himself.

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

Seeing everyone's reactions, Xu Ziling smiled in his heart, and said: If there is no such function, I will not be making a big fuss about this project.

The next thing to test is one of the most important functions for a submarine: navigation!

The navigation system of a submarine is much more complicated than that of ships at sea. There are astronomical navigation systems, radar navigation systems, satellite navigation systems, short-range and long-range radio navigation systems, inertial navigation systems and integrated navigation systems. Only the inertial navigation and integrated navigation are used.

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

At the beginning, Xu Ziling considered that the microwave signal of "Eagle Eye" could easily penetrate the water quality with only a negligible loss, so he considered that this characteristic could be used for navigation.

When the system is turned on, since there is no seabed topographic map in the system, the navigation interface is just a map with detailed latitude and longitude marked. After a brief connection with the satellite, a green dot is displayed on the map.

"Because there is no seabed topographic map in the database, we can only display this kind of electronic map with only longitude and latitude for the time being. This green point represents our submarine. After the system is perfected, ships and submarines in the entire ocean will be in the same system network. Inside, if there are other ships and submarines nearby, it will be displayed on it." Xu Ziling pointed to the map displayed on the screen and explained, "As for the topographic map of the seabed, it is definitely impossible to collect it all at once, and it is not by a ship. The ship can be collected by running around the world. It is still in the testing period, and it will not be put into practical use for the time being. You can use it while collecting. By the way, when the system is working, it will automatically collect these maps at the same time. As for the complete map, I will want to collect it completely when the time comes,"

The sea area occupies three quarters of the entire earth. One can imagine how wide it is. The small "Hawkeye" mounted on the ship now scans only a radius of [-] kilometers, and the long-distance Hawkeye is too expensive. , It is not suitable for large-scale equipment, so it is unrealistic to collect the bottom topographic map of the entire sea area by ships or submarines sailing in the sea.

Because the tonnage of a ship that is going to sail on the sea for a long time must not be small, and the tonnage is not small, which will limit its speed on the one hand. According to statistics, the earth's sea area is nearly 4 million square kilometers. Calculated at a speed of 30 knots, it can only scan a range of [-] kilometers in diameter at a time. It is conceivable that this ship needs to run non-stop on the ocean for many years to collect the entire map, so this method is definitely not advisable.

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

Xu Ziling had thought about the map for a long time, and he rejected all these methods. His idea was to use the reconnaissance plane or wait for the "Space Hawkeye" to be successfully launched, and then do it all at once. For a while, he still felt that it would be best to get the "Hawkeye" ready after it was arranged. Anyway, he was not in a hurry at this time, so he told everyone to wait for him to find a solution in the future.

Compared with submarine communication, submarine navigation undoubtedly makes people feel more real and shocking, especially after "Hawkeye" collected the submarine topographic map within a range of [-] kilometers, Xu Ziling signaled that the submarine started to start and set it to automatic navigation. In the sea at a depth of several hundred meters, when the navigation system automatically reported all navigation data, everyone was dumbfounded.

"The main reason is the limitation of the submarine. In my vision, the submarine can be fully automated, just like an airplane. As long as the automatic cruise is set, it can drive automatically, instead of just reporting some data as it is now. Understand."

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." After hearing what he said, Professor Xie turned to Xu Ziling and said, "Although I don't know this industry, I also know that submarines, unlike aircraft and ships, can navigate automatically. It is mainly because of the problem of being underwater, but now with this kind of navigation technology, it is indeed possible to develop in this direction.”

"It's not too difficult, I have some ideas." Xu Ziling doesn't mind being known about some problems, "Automation is just an inevitable trend, and I'm also considering developing large-scale unmanned submarines on this basis."

"what……"

The two men discussed technical issues in such a serious manner, but Captain Li and some people were dumbfounded. In their opinion, a submarine that can initially have automatic navigation is already a leading technology in the world, and they actually want to come up with fully automatic cruise control. Submarines, after that, will there be no need for many people in the submarines?Three or two people can operate a submarine?

"This is just a plan. Even if we start relevant research now, it won't be completed in three to five months." Hearing Captain Li's surprise, Xu Ziling turned 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 automatic control scheme. At that time, Xu Ziling was thinking that fully automatic driving is the development trend of submarines in the future.

However, the optimization plan is based on the overall optimization of the original submarine. Communication, positioning and other aspects have been optimized, but it needs to be able to cooperate with satellites and ground equipment to play a role, but these are not in the optimization plan. Things, so There are many solutions that cannot be worked out now.

Now with the emergence of "Space Hawkeye", it can be said that it completely filled the gap in this aspect, so Xu Ziling was determined in his mind, considering that Jiangnan Plant will develop submarine automation after the completion of the warship project. Research.

In his opinion, the submarine is so big, the fighter plane is relatively smaller than it, and they have realized automatic cruise. There is no reason why the submarine cannot be successful. 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 won’t work. Now that the “Eagle Eye” has solved this problem, it is absolutely necessary to invest in research on automation, and it probably won’t It is a difficult thing.

Of course, what he values ​​most is the large unmanned submarine.

Unlike airplanes, submarines face a more complex deep-sea environment. Pilots still have the opportunity to parachute to escape when the plane crashes, while the crew can only die and wait for rescue before the oxygen in the boat is exhausted.In this sense, unmanned submarines may play a greater role than unmanned aircraft on the future battlefield. It is also from this aspect that Xu Ziling made up his mind to start researching the unmanned of large submarines.

Unmanned submarines were developed by countries as early as decades ago. However, due to the constraints of underwater communications and other reasons, even after decades of development, there has not been much development in this area. The main application areas of submarines are still in civilian use: from salvage to rescue, seabed exploration; and in military aspects, there are only a few uses such as mine countermeasures and network nodes during wars.

The existing unmanned submarines are all controlled by remote control, because it is very complicated and difficult for unmanned submarines to communicate with the outside world, and it is necessary to strike a balance between confidentiality and transmission efficiency.Therefore, there is only one slightly mature way of remote control: transmitting signals through cables.However, this method has a huge disadvantage, that is, the maneuvering range of the unmanned submarine will be limited.

Think about it and know that when a submarine wants to operate, it definitely needs a release platform, or a ship, or an aircraft carrier, but you can’t drag a cable several kilometers or tens of thousands of meters long to control the submarine, right?Therefore, using this remote control method is not a desirable method at all in the long run. When the war starts, the distance of more than 1000 meters has no meaning at all. It can only be used to clear mines in non-emergency situations.

The microwave signal of "Eagle Eye" has completely solved the problem of difficult communication. Therefore, if submarines want to develop unmanned, they can use wireless communication technology. The new communication method fundamentally breaks through the original limitations. , you can completely abandon the cable control method with too obvious disadvantages.

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