    At this time, Zhang Wenhao smiled calmly and said to the more than 10,000 people in the audience: "The 4D map you saw in the opening video will be integrated with the positioning terminal of Dongchen Positioning System. At that time, we will provide three modes  There are maps for everyone to choose. The first type is a traditional 2D map; the second type is a flat 3D map. I think friends who are familiar with Google Earth should understand what a flat 3D map is; the third type is a convenient  It is this kind of 4D map with all-round free angles. The viewing angle is no longer the same as the previous two, directly above you, but can be switched and positioned at will. As you can see in the opening video, it is very realistic and very  interesting."

    Speaking, Zhang Wenhao added: "However, different terminals have different corresponding functions. For the current mass application field, we have launched three positioning terminals for the whole society. One is the updated Dongchen positioning module.  Universal, the other is Dongchen¡¯s vehicle-mounted positioning system, and the other is a handheld positioning terminal specially launched by Dongchen.¡±

    "The functions of these three terminals are somewhat surprising. For example, the Universal terminal and the handheld terminal do not have an adaptive system. In other words, it is a simple positioning system. Unlike the vehicle positioning system, it can integrate the information of the entire vehicle.  All inputs are included. When navigating and positioning, the navigation cursor is the entire vehicle rather than a single positioning point. This may not seem interesting, but it is actually very important. If you have your own parking space, then after parking the car,  , you can let the positioning system record your coordinates at this moment. In this way, combined with Dongchen Automobile¡¯s original 360-degree driving radar, you can park the car into your parking space with the most accuracy and safety. If it is Dongchen Automobile,  For high-end models, your automatic parking system will be more relaxed and convenient under the guidance of the parking space coordinates. Every time you go home to park, you don¡¯t need to set any data. The automatic parking system can automatically park your car.  Park in your own parking space."

    "In addition, another advantage of the vehicle-mounted terminal is that it can change its positioning point at will just like in the movie. Although this is not very practical, it can still be very useful in special circumstances.  effect."

    The audience listened in rapt attention, and Zhang Wenhao then spoke: "You just saw in the short video that the Dongchen positioning system has an altitude display. I want to explain this to you. The Dongchen positioning system is far from being as simple as you think. He  Not only can it provide positioning accuracy of less than one centimeter in plane positioning, but the positioning accuracy at altitude is also less than one centimeter."

    As soon as this statement came out, everyone in the audience was shocked!

    ??Altitude?

    What method can be used to accurately measure altitude?

    Seeing everyone's expressions of shock, Zhang Wenhao explained with a smile: "As we all know, there are two ways to measure altitude. One is to use physical principles, that is, air pressure detection, and the other is to use existing  GPS positioning system.¡±

    "However, the former has a problem, that is, the measurement is not linear enough. To put it bluntly, the accuracy is not high enough. It can only measure an approximate value, and the response speed is very slow. The latter has another bigger problem, that is, error  It¡¯s too big, and the signal is extremely susceptible to interference. The measurement on the ground may be more accurate, but once it is off the ground, it is simply difficult to use GPS to measure the accurate altitude.¡±

    "And Dongchen's positioning system can already achieve accurate altitude measurement. This means that this system is not only suitable for the ground, but also suitable for the air."

    ¡°As he spoke, Zhang Wenhao said, ¡°Please read another short story.¡±

    Immediately afterwards, the short story was played again, and the scene of a test airfield appeared on the big screen. However, this time the measurement was not the process of Zhang Wenhao testing with the gang of soy sauce gangs, but a video taken by Dongchen when he was measuring alone.  .

    Zhang Wenhao explained on the side: "Our positioning system is installed at the bottom of the front end of the helicopter. The distance from the ground is 0.6 meters, so we have already subtracted the 0.6 meter error during installation, that is to say  , the altitude we display in real time is not based on the front end of the aircraft, but on the bottom of the front wheel of the helicopter. Next, please take a look at what height the Dongchen positioning system can measure the altitude.  Bar."

    At this time, the helicopter engine started to start. After a while, the helicopter began to climb. Before the altitude meter on the aircraft gave any response, Dongchen's positioning system had already given a response. The altitude still increased slowly in centimeters.

    The screen is switched to two, one showing the altitude data, and the other camera on the outside recording the situation of the aircraft's front wheel lifting off the ground at the same time.

    1 cm, 2 cm, 3 cm.

    The altitude data given by the Dongchen positioning system is extremely accurate and quickly highlights the entire climbing process of the aircraft at this moment. This is also the last time Zhang Wenhao chose to use a helicopter for testing.Big Purpose - Very intuitive.

    The helicopter made a simple takeoff and landing. During the entire process, the Dongchen positioning system accurately displayed the altitude of the aircraft. Moreover, this system is very smart. Before the aircraft takes off, it first calculates the altitude of the ground, and then,  When climbing, while displaying the altitude, the actual altitude of the aircraft relative to the ground is displayed by subtracting the ground altitude from the real-time altitude.

    Professionals from the U.S. military who followed Raymond could see at a glance the huge role this system has in the military field, especially the Air Force. Oh my god, this perfect and precise support for altitude was simply developed specifically for the Air Force.  Customized functions, if Dongchen makes this positioning terminal open to civilian use, then all the U.S. air forces can benefit a lot from this. After all, even if ordinary civilian terminals do not support other ancillary functions, its core demands have been highlighted  It is very clear. First, the positioning is extremely accurate. Second, the altitude positioning is extremely accurate, and the real-time response speed is almost error-free and delay-free. These two points are very, very useful to the Air Force.

    At the same time, in the United States, the senior officials and technical personnel of the U.S. Air Force were extremely excited when they saw this place. One engineer even held a beer in one hand and pointed at the TV with the other and said: "If Dongchen puts this kind of  Once the terminal is opened for civilian use, we will immediately add Dongchen¡¯s positioning module to all our aircraft. In this case, we will also mark all our airport runways. This will greatly improve the efficiency and safety of the Air Force.  !¡±

    Another engineer also said: "In this case, if we use his module as the core and develop other auxiliary functions ourselves, I believe it will be very practical!"

    Just when they were excited, Zhang Wenhao sent them to hell with one sentence.

    Zhang Wenhao said with a bad smile: "Because of all factors and considering that civilian demand for altitude data is not large, all civilian positioning modules released by Dongchen will limit the altitude function.  We will not completely eliminate the altitude display function, but we will impose necessary restrictions on the real-time nature of the altitude display. Therefore, all civilian positioning terminals do not have the ability to display accurate altitude data in real time. Accurate altitude data is only available every ten minutes.  It will be updated once, but the approximate altitude will be displayed in real time. The approximate altitude displayed in real time will have a positioning accuracy error of about 5 meters."

    Just after saying this sentence, the originally excited military forces of various countries suddenly felt as if they were falling into an ice cave. **, accurate altitude data is only updated every ten minutes. If this thing is used on an airplane, the day lily will be cold.  ten minutes

    The real-time altitude display does not have high accuracy. Isn¡¯t this a scam?

    Although for the military of various countries, Dongchen's killer move has completely stopped them from thinking about it, but for the vast majority of ordinary users, real-time high-precision altitude is basically meaningless to them. Therefore, this  It has not affected their enthusiasm for Dongchen satellite positioning system at all.

    At this moment, Zhang Wenhao on the stage seemed very calm and confident. He said: "Now, we invite everyone to watch another video. This video is a bit special. Most of the shots were shot with high-power infrared cameras.  , as for what kind of mystery there is, please find it yourself."

    With that said, the big screen played the prepared video material again. This time, the audience discovered that the video was taken at an airport. The camera captured it from a high position and captured the only plane on the tarmac, a Boeing 737 passenger plane.  , the airport does not look like a passenger airport, but many staff wearing special clothes are busy next to the 737. It seems that everyone's attention is focused on this common 737.

    There was a sound similar to that coming from a walkie-talkie in the video. The video also had bilingual subtitles in Chinese and English. Just listen to the voice saying: "The ground work is ready, and the staff are working on the sidelines for the landing gear of the aircraft."

    Zhang Wenhao's voice came, saying: "Draw the change line and prepare to take off."

    At this time, the screen switched to the side of the aircraft. You can see three staff members holding spray painting equipment, spraying white borders around the three landing gears of the aircraft, and completely drawing the landing gears into the borders.

    A staff member on the ground held a walkie-talkie and said: "Everything is ready."

    Zhang Wenhao's voice said: "Okay, stop all lighting!"

    "Received, terminate all lighting."

    In an instant, the picture captured by the high-altitude camera fell into darkness. Except for a little light in the far distance, the entire airport was immersed in darkness. At this time, the B737's engine sounded and the plane started.

      The picture immediately switched to the high-power infrared camera. Through the infrared camera, everyone can see that the 737 has started the engine and slowly started to draw out of the parking space. At this time, the lights in the cockpit of the aircraft came on. Under the infrared camera,  It looked extremely clear, and the focus of the infrared camera was also enlarged, making the cabin image closer and closer. The entire scene suddenly let out bursts of exclamations, because they saw that there was not a single person in the entire cockpit. To be precise,  This plane is unmanned!

    Unmanned aircraft are not a gimmick. After all, the United States began to use drones for reconnaissance and attacks more than ten or twenty years ago. However, drones all over the world follow the same routine, that is,  The cockpit is moved out and fixed on the ground. Although there is no one piloting the aircraft, there is a dedicated person on the ground to fly the aircraft. Therefore, fundamentally speaking, this is still a manned aircraft.

    " However, Dongchen's 737 is different. It is truly unmanned, and it operates under extremely harsh visual conditions with almost no sight distance.

    At this time, the narrator said in Chinese with English letters: "This plane is not an ordinary plane. It has no pilot and no one is controlling it on the ground. All its flight trajectories have been set and stored in  In its flight computer, the coordinates used for its flight trajectory are completely provided by the Dongchen satellite positioning system. The coordinate accuracy is less than one centimeter. The aircraft's navigation control is also based on the modified Dongchen satellite positioning terminal. Therefore, the aircraft can  It can perfectly execute the flight on the designated route, even without a driver and without any visual distance for reference.¡±

    When the narrator said this, the plane had already taxied a long way away and was preparing to enter the runway. The entire taxiing route of the plane followed the white center line exactly.

    When the aircraft turns and enters the runway, the aircraft's engine begins to increase power, and the entire process from afterburner to lifting the front wheel to taking off is completed in one go.

    After the plane took off, the picture switched to the picture taken by an ordinary high-definition camera. In the dark night sky, only the flashing lights on the tail of the plane could be seen. After the plane flew a standard final, it began to land. During the landing process, the plane also perfectly executed the plan.  A good route starts from deceleration to descent in one go. The plane lands smoothly, decelerates, and then returns to the starting point along the route. When the plane finally stops, its landing gear tires are in the same position as before.  There are almost no gaps discernible to the naked eye.

    At this time, the audience was completely silent, and Raymond was sitting on the chair with a pale face. Such a powerful accuracy cannot be achieved by any pilot. It is too accurate, as precise as an embroidery needle.  Rather than a behemoth aircraft, Raymond could see the huge significance contained in it at a glance. Once this system is moved into the aircraft, one thing that is certain is that the aircraft can complete precise takeoff and landing without line of sight.

    What does this mean for airlines?  This means that the cost can be better reduced. Every airline that flies multiple direct routes often encounters weather conditions that prevent it from taking off and landing, which means that the utilization rate of the aircraft is reduced. If it is delayed for two hours, there will be fewer aircraft.  Earning two hours of profit and not being able to land means that the plane must be diverted to other airports. The extra flight distance, extra take-off and landing process, and waiting process will all add huge additional costs. However, if Dongchen¡¯s set  If the system is promoted, the inability to take off and land due to line of sight can be completely avoided. Moreover, this system will undoubtedly better increase the airport's utilization rate and the take-off and landing efficiency of the entire airport's inbound and outbound flights. It is powerful  , and it is not ordinary powerful, it is simply abnormally powerful!

    Raymond can even foresee that if Dongchen uses this system and Dongchen Aviation's engines as dual auxiliaries in the future, it will be impossible for Boeing to compete with Dongchen in the market even if it integrates its own and Airbus technologies.  , not to mention, God knows what new technologies Dongchen will apply on aircraft in the future?  !

    God, Raymond¡¯s heart sank to the bottom. It can be foreseen that after this press conference, Boeing¡¯s stock will suffer another setback!  Last time Dongchen acquired Airbus, it had already fallen sharply. It finally rose after Boeing acquired Airbus's patented technology and R&D personnel. Now, Dongchen has used its trump card. I'm afraid Boeing  The stock will never be successful again!

    In the stock market, the evaporation of market value in one day may cause tens of billions of market values ??to disappear. Raymond is really afraid, even he is afraid, not to mention the stock investors?

    People in the civil aviation system around the world are excited about this amazing result. Airlines see the prospect of high-efficiency flights in the future, and air traffic control departments also feel that such a strict and accurate positioning system can provide them with more accurate air traffic control assistance.  , when the time comes??, existing routes can be compressed, and within the same height interval, routes can even be arranged several times more than before, greatly increasing the utilization of routes, and the airport is also very excited. As the aviation industry becomes more and more developed,  , airports all over the world are facing a big problem, that is, the turnover speed is too slow and the load is too large. However, with this system, their airport utilization rate can be higher, without investing in hardware expansion, and they can also withstand higher density.  , a larger number of aircraft entering and leaving the port.

    at this time.  Zhang Wenhao spoke.

    "As everyone knows, Dongchen has just completed the acquisition of Airbus some time ago. Now, we are already reintegrating Airbus' hardware. It won't be long before Dongchen's first civil aviation aircraft will be rolled off the production line.  As the test flight begins, one thing that is certain is that the system just now is by no means the only highlight of Dongchen¡¯s aircraft. In fact, I can assure you that the supersonic passenger aircraft you saw at the beginning is the next step in Dongchen¡¯s development.  The goal is to achieve the goal, and it won¡¯t be long before everyone can see the actual product.¡±

    After saying that, Zhang Wenhao paused and then said: "In addition, I also have a promise, that is, the supersonic passenger aircraft produced by Dongchen will only be operated by Dongchen's own airline.  , Dongchen will become the only airline in the world to operate supersonic passenger services. Perhaps in the near future, everyone will have the opportunity to travel around the world on Dongchen's supersonic passenger aircraft, with a cruising speed of 3,600 kilometers per hour.  Please wait and see what the promise is!"
