C428 A King That Can Change the World(part Ii)
After saying that, Zhang Yunfeng continued, "However, different terminals have different functions. In the current mass application field, we have launched three types of GPS terminals that are aimed at the entire society. One is the updating of Dong Chen's localization module, and the other is the onboard positioning system of Dong Chen's car. The other type is the hand-held GPS terminal that Dongchen specially introduced. "
"The functions of these three types of terminals are a bit strange. For example, the unevenal terminal and the handheld terminal do not have a self-adapting system. In other words, it is a simple positioning system, unlike a vehicle's positioning system. It can input all the information in the entire vehicle into the navigation and positioning system. The GPS was a whole car and not a single location, which seemed meaningless. But it's actually very important. If you have your own parking space, after parking the car, you can get the GPS to record your current coordinates. This way, coupled with the original 360 degrees radar of the Dongchen Automobile, you can accurately and safely park your car in your own parking space. If it is a high-end model of Dong Chen's car, then your automatic parking system. Under the guidance of the coordinates of the parking space, it will be more convenient and convenient. Every time he went home to park his car, he did not need to set any more data. The automatic parking system will automatically move your car into your own parking space. "
"Other than that, there's another benefit of the terminal, which is that it can be like in the movie just now. It can change your position as you wish, although it is not very practical. However, in a special environment, it can still be very effective. "
Below the stage, Zhang Yunfeng was listening attentively. He then said, "Just now, everyone saw that Dong Chen's positioning system has an altitude indicator in the short film. I want to explain this to everyone. Dong Chen's GPS system is not as simple as you think it is. Not only can he provide an accuracy of less than one centimeter in the plane positioning, but he can also provide an accurate positioning of the altitude. It's also less than one centimeter."
When he said this, everyone was shocked!
Highland?
What method could accurately measure the altitude?
Zhang Yunfeng saw that everyone was shocked, so he smiled and explained, "As everyone knows, there are two ways to measure the altitude now. One is to use the physics principle, which is to test the air pressure. The other is to use the existing GPS positioning system."
"However, there is a problem with the first method, which is that the measurements are not linear enough. To put it bluntly, the accuracy is not high enough, and can only roughly measure one. Moreover, the reaction speed is very slow. As for the latter, there is an even bigger problem. The error was too great, and the signal was very easily disrupted. The measurement on the ground might be more accurate, but once it left the ground, to use a GPS to measure the altitude accurately is as difficult as ascending to the heavens. "
"And Dong Chen's GPS can already accurately measure the altitude. This means that this system is not only applicable to the ground, but also in the air."
Zhang Yunfeng said, "Please read another short piece."
Immediately after, another short piece was released at the scene, and the scene of the test flight airport appeared on the big screen. However, this time, the test was not done by Zhang Yunfeng and the gang of soy sauce. It was a video taken by Dong Chen when he measured alone.
Zhang Yunfeng explained from the side, "Our positioning system is installed at the bottom of the front end of this helicopter. The distance from the ground is 0.6 meters, so when we installed it, the error value of 0.6 meters has been reduced. In other words, the altitude that we displayed in real time is not based on the front end of the helicopter. Instead, it is based on the bottom of the front wheel of the helicopter. Next, everyone, please take a look at the height of the altitude measured by Dong Chen's GPS system."
At this time, the helicopter engine started to move. A moment later, the helicopter started to climb. Before the altitude meter of the helicopter could give any response, Dongchen's GPS had already given a response. The height was still increasing slowly by a centimeter.
The scene changed into two. One displayed the altitude data, and the other was a camera that was recording the plane's front wheel leaving the ground at the same time.
One centimeter, two centimeters, three centimeters.
The altitude data provided by the Dongchen GPS was extremely accurate and quickly highlighted the entire process of the plane climbing up. This was also the biggest reason Zhang Yunfeng chose to use the helicopter for the test. It was very direct.
The helicopter flew up and down in a simple manner, during the entire process. The Dongchen GPS displayed the height of the helicopter accurately. And... This system was very intelligent. Before the plane took off, it first calculated the altitude of the ground, then, when climbing, on one side, it showed the altitude of the sea, and on the other side, it used the real-time altitude of the sea to subtract the altitude of the ground. It showed the actual height of the plane compared to the ground.
The professionals from the American military who came with Raymond saw the huge use of this system in the military field, especially the air force. God, this perfect and precise support to the altitude was simply a customized function specially developed for the air force. If Dong Chen were to publicize this kind of GPS terminal to the public, then... All the air forces in the United States would benefit greatly from this. After all, even if ordinary civilian terminals did not support other auxiliary functions, but... Its core appeal was very clear. First, extreme accuracy in positioning. Second, extreme altitude positioning. And the real-time response speed was almost accurate and delayed. With these two points, it was already very useful for the Air Force.
At the same time, in the United States, the UA Air Force's upper echelons and technical staff were also extremely excited when they saw this. Even an engineer with a beer in one hand and a TV in the other. He said, "If Dong Chen releases this kind of terminal for civilian use, we will immediately add Dong Chen's localization module to all our aircrafts. In that case, we will also mark down all of our airport runway. This will greatly increase the efficiency and safety of the Air Force! "
Another engineer also said, "In that case, we will use his modules as the core and develop our own subsidiary functions. I believe that it will be very useful!"
Just as they were excited, Zhang Yunfeng's words sent them to hell.
Zhang Yunfeng said with an evil smile, "Because of various factors, and considering that the civilian demand for altitude data is not high. Therefore, all the civilian localization modules that Dong Chen released will restrict the function of altitude. We will not completely erase the function of altitude localization. But... We will put a necessary restriction on the real-time performance of the altitude display... Therefore, all civilian localization terminals do not have the ability to display precise altitude data in real-time. The precise altitude data will only be updated every ten minutes. But... It would show a general altitude in real time, and a general altitude in real time. The error in positioning accuracy will be around 5 meters. "
As soon as he said this, the military from various countries, who were originally extremely excited, suddenly felt as if they had fallen into an ice cave. Damn it, the precise altitude data would only be updated once every 10 minutes. If this thing was used on the plane, even the corns and vegetables would turn cold. Ten minutes...
A real-time altitude display and I don't have high precision. If this isn't a scam, then what is it?
Although to the various countries' military, this killer move of Dong Chen had completely cut off their thoughts. However, for most ordinary users, real-time high precision altitude was basically meaningless to them. Therefore, this did not affect their enthusiasm for Dong Chen's satellite positioning system at all.
At this moment, Zhang Yunfeng on the platform seemed very calm and confident. He said, "Now, let's invite everyone to watch another video. This video was a bit special. Most of the scenes were... As for the mystery behind it... Please go and find out yourself "
After saying that, the big screen once again played the prepared video data. This time, the audience discovered that the location of the video was an airport. The camera captured from a high position and captured the only plane on the tarp. A Boeing 737 passenger plane, the airport didn't look like a passenger airport. Many staff members in special clothing were busy at 737, as if they were all paying attention. They were all focused on the 737 that they were used to.
A similar sound came from the walkie-talkie in the video, and on the video, there were words in English and Chinese. The voice said, "The ground work is ready, the staff is making a boundary for the landing gear."
Zhang Yunfeng's voice came over. He said, "Once the line is drawn, prepare to take off."
At this time, the scene changed to the side of the plane. Three staff members were holding the equipment used to spray paint. They circled around the three landing gear and sprayed out white borders, drawing the landing gear completely into the boundary.
A staff member on the ground said to the speaker, "Everything is ready."
Zhang Yunfeng said, "Okay, stop all lighting!"
"Roger, stop all lighting."
In an instant, the scene captured by the high-leveled camera fell into darkness. Apart from a few dots of light in the distance, the entire airport was immersed in the darkness. At that moment, the sound of the B737 engine was heard and the plane started up.
The scene immediately switched to the high-power infrared camera, through the infrared camera. Everyone could see that the 737 had already started the engine and was slowly drawing a stop. At this moment, the lights in the cockpit lit up, making it appear especially clear under the infrared camera. The focus of the infrared camera also increased, drawing the scene of the cabin closer and closer. The entire scene suddenly let out a series of exclamations, because they could see that... There was not a single person in the cockpit. To be precise, this airplane was unmanned!
Unmanned aircraft was not a gimmick. After all, America had started using drones to investigate and attack more than twenty years ago. However, all drones in the world were the same. That is, move the cockpit out and fix it on the ground. Although no one is piloting the plane, there are people on the ground to pilot it. Thus, fundamentally speaking, this was a plane that was piloted by someone.
However, Dong Chen's 737 was different. It was truly unmanned, and it was under extremely poor visual conditions without any visual range.
At this time, the commentator said in Mandarin with English letters, "This plane is not an ordinary plane. It doesn't have a pilot. No one was controlling it from the ground. All of its flight paths had been set. It's stored in its flight computer, and its flight path... The coordinates used were all provided by the Dongchen Satellite Positioning System. The accuracy of the coordinates was less than one centimeter. The flight control of the plane was also based on the modified Dongchen Satellite Positioning Terminal. Therefore, the plane could perfectly carry out the designated flight route. Even if there is no one to pilot it, even if there is no visual reference. "
Speaking up to this point, the plane had already flown a very long distance, and it began to prepare to enter the runway. The route that the plane had flown through was completely following the white middle line, and it could be said that it was exactly the same.
When the plane turned around and entered the runway, the engine of the plane began to accelerate. From the acceleration to the lifting of the front wheel and taking off, the entire process was completed in one go.
After the plane took off, the scene changed to that of a normal high-definition camera. In the dark night, only the flickering lights at the tail of the plane could be seen, and after the plane flew a standard five-way, the plane started to land. During the process of landing, the plane perfectly executed the designated flight route. From deceleration to deceleration, the plane landed smoothly and decelerated in one go. Then, he followed the route and returned to the starting point. When the plane finally came to a stop, its landing gear tires... There was almost no gap that could be seen with the naked eye from its previous position.
At this moment, the audience was completely silent. Raymond sat on the chair with a pale face. This kind of high precision was something that no pilot could achieve. It was so precise that it was like an embroidery needle. Raymond could tell at a glance that it was not a huge plane. Once this system was moved into the plane, there was one thing he was sure of: The plane could accurately take off and land without any distance.
What did this mean to the aviation company? It means that the cost can be lowered even better. Each airlines, flying straight for multiple routes would often encounter weather problems that could not be lifted or dropped. If they could not take off, it meant that the utilization rate of the aircraft would be lowered and there would be a delay of two hours. The aircraft would earn less profit of two hours, and they would not be able to land. This meant that the aircraft had to be prepared for landing at other airports, the extra flight schedule, the extra landing process, and the waiting process. All of these would increase the cost of the aircraft. However, if Dong Chen's system was promoted... Then... The inability to take off and prepare for landing due to the distance could be completely avoided. Furthermore, this system would undoubtedly increase the utilization rate of the airport and the efficiency of the landing and landing of the entire airport and port flights. It was powerful, and it was not an ordinary kind of power. It was simply abnormal and powerful!
Raymond could even foresee that in the future, if Dong Chen used this system and the Dongchen Aerospace Engineering's engine as a double support, then even if the Boeing integrated his and the Airbus' technology, it would still be impossible for him to compete with Dong Chen in the market. Furthermore, who knew what new technology Dong Chen would use on the plane in the future!
Oh my god... Raymond's heart sank to the bottom of the valley. He could foresee that after this press conference, boeing's shares would suffer another setback and fall! Last time, because of Dong Chen's purchase of vacancies, it had fallen by a large margin. It was only after much difficulty that the number of aircrafts' patents and research staff in Boeing increased. Now, dong Chen had used his trump card. It was afraid that Boeing's shares would no longer have a chance to make a name for themselves!
In the stock market, the evaporation of the market value within a day could cause tens of billions of market value to disappear. Raymond was really afraid. Even he was afraid, let alone the shareholders.
The people of the entire world's civil aviation system were excited about this amazing result. The aviation company saw the future of high efficiency flying in the future. The air traffic management department also felt that such a strict and precise positioning system could provide them with more precise air pipe assistance. At that time, the current route could be compressed within the same altitude gap. It could even be arranged into a route several times higher than before, greatly increasing the utilization rate of the route. The airport was also very excited. As the aviation industry became more and more developed, the entire world's airports faced a huge problem, which was that the speed of the turnover was too slow. The load was too great, but with this system, it could increase the utilization rate of their airports, and they wouldn't need to invest in the expansion of the hardware. They would also be able to withstand a larger number of airplanes entering and exiting the port.
At this moment. Zhang Yunfeng spoke.
"Everyone knows that Dong Chen just finished purchasing the passengers a while ago. Now, we are reorganizing the hardware of the passengers. It won't take long for Dong Chen's first Civil aviation aircraft to log off and begin the test flight. One thing we can be sure of is that the system just now... It is definitely not the only highlight of Dong Chen's flight. I can even guarantee to everyone that... The supersonic plane that everyone saw at the beginning was also Dong Chen's next target. Furthermore, it won't take long for everyone to see the actual product. "
Zhang Yunfeng paused for a moment and said, "Other than that, I have another promise, and that is... The supersonic passenger planes produced by Dong Chen will only be operated by his own aviation company. At that time, Dong Chen will be the only aviation company in the world that can operate supersonic passenger services. Perhaps in the near future, everyone would have a chance to ride Dong Chen's supersonic passenger planes and travel around the world. Our promise is that we will cruise 3,600 kilometers per hour. Please wait and see!"
