When the helicopter began to take off, a group of people discovered that this handheld Dongchen positioning terminal, how powerful its function is, the helicopter's own altimeter, in feet is increasing, and the positioning terminal of Dongchen, the sensitivity to altitude is increasing in centimeters, and the terminal in addition to displaying the current altitude, can also calculate the ascent speed of the helicopter at this moment by calculating the alternation of coordinate points within a certain period of time.

A group of experts of the Beidou system were dumbfounded, but the military people were excited, good guys, if this set of things is installed on the plane, and the data of this system is used to direct the aircraft to carry out automatic driving, then the accuracy of this automatic driving will far exceed that of the pilot!

The helicopter climbed to an altitude of about 1,000 meters above sea level, Zhang Wenhao said: "The handheld terminal also has a function, that is, route recording, no matter at any time, as long as the recording function is turned on, the terminal will record your most accurate three-dimensional movement route, including the change of plane position, the change of altitude, because we have added Dongchen's unique processing chip to the handheld terminal, so, the terminal is very fast and very accurate in calculating such dense coordinate points, If in the future you apply this terminal to the navy, land and air force, then I can ensure that you know the location and movement of all the vehicles, ships, and aircraft on which this terminal is installed. ”

An Air Force engineer asked, "How do we count such a large number of terminals?" Will Dongchen open up the function of real-time coordinate sharing? ”

Zhang Wenhao said indifferently: "We will give the military a special authority, and when the time comes, we will provide the military with a 'management background'." All the Dongchen positioning modules installed on the military's weapons and equipment will be included in the controlled objects of the management background. Such. When you go to the backend, you can see the real-time dynamics of a single, partial, or even all controlled objects. ”

Speaking, Zhang Wenhao said: "If the military wants to upgrade its own UAV, Dongchen can provide a set of automatic control system based on Dongchen's positioning system, when the time comes, you only need to designate any target, and then set the task, and the automatic control system can command the drone to execute accurately." ”

The military representatives were suddenly excited, and the whole person was a little crazy. He blurted out and asked: "When will such a system and enough terminals be put into practical use?" ”

Zhang Wenhao said: "A month? We have now started to produce terminal modules, and we only need to wait for all our satellites to be launched into orbit and for us to achieve global coverage, and the entire Dongchen positioning system, whether it is civilian or military, can be activated immediately. ”

The military representative counted his fingers, exclaimed, and said: "From the launch of the first satellite to the full entry into practical application, the whole process only takes less than two months?" That's too fast, right? ”

Zhang Wenhao smiled slightly and said, "This is Dongchen speed." When a new technology is born, it must be pushed into practical application as soon as possible. Otherwise, a system that has been built for 20 years with the technology of 20 years ago will finally be built after 20 years, and it will be outdated as soon as it is built. ”

These words were obviously said to the experts of Beidou, which also made the experts who were a little skeptical of the Dongchen positioning system at the beginning red-faced.

Within two months, build a global positioning system, which is already incredible, not to mention, the technology used in the system itself, at least decades ahead of Beidou, once Dongchen's system completes global coverage, then Beidou can also be officially laid off, hateful, Beidou has not completed global coverage until now!

Immediately, Zhang Wenhao said: "Dongchen positioning system, not only to meet the positioning of this simple service, because the positioning accuracy is extremely high, and very stable, so, I think, this system can be extended to many aspects in the future, for example, high-speed trains on high-speed railways if each train is equipped with Dongchen's positioning system, and then, we can develop a dispatching system based on the development of Dongchen positioning system for the railway department, the position of the train, the speed, the distance between the front and rear cars, The display in the dispatch system will be extremely accurate. ”

"If the military needs more accurate satellite guidance, then we can also open guidance services to the military, and all your needs for precise location can be met from Dongchen."

For these so-called experts and military engineers, Zhang Wenhao was not prepared to let them participate in the test of the system from the beginning, and Zhang Wenhao's purpose was to use his own method to demonstrate the excellence and incomparable of the Dongchen positioning system.

The helicopter is constantly flying around the airport, and these experts also see from the terminal in their hands that the terminal is constantly recording the flight trajectory of the aircraft getting longer and longer, and it is really a three-dimensional trajectory as Zhang Wenhao said, and it is almost exactly the same.

However, this is only a demonstration of the accuracy and extension function of the Dongchen positioning system, and Zhang Wenhao can put the second test at 9 o'clock in the evening for how to reflect the application of the Dongchen positioning system at a higher level.

This test, the use of a modified Boeing 737, the Boeing 737 positioning system, altitude, ground speed, airspeed and other data sources have all been modified, all data are provided by the Dongchen positioning system, and the aircraft's automatic driving function, has also been upgraded, and matched with the Dongchen positioning system, it can be said that this aircraft, currently equipped with positioning and automatic driving system, is Zhang Wenhao in the future to be applied to the full set of technology on Dongchen's own aircraft.

Nowadays, the so-called automatic driving of civil airliners, to put it bluntly, is nothing more than locking the coordinates after taking off and entering the cruising altitude, and the aircraft realizes self-flight in the air, but when it comes to real automatic take-off and landing, this is basically equivalent to a fool's dream.

However, Zhang Wenhao not only had to let the 737 take off and land automatically and fly automatically, but even simulate the worst situation, that is, there was no visual state at all.

The whole airport fell into darkness, the tower, buildings and the guiding lights on the runway were all turned off, if you stand high enough to look at the airport, people will even feel that this is a blank area, this is also the extremely bad sight distance that Zhang Wenhao is pursuing, to put it bluntly, there is no sight distance at all.

Zhang Wenhao invited Director Liu and his entourage of more than a dozen people, and said: "This plane will not be equipped with a pilot, from launching the hangar, to entering the runway through the link line, taking off, flying and finally landing, all of which are completed by the automatic driving system with the Dongchen positioning system, I don't know if any of you dare to board this plane with me?" ”

As soon as I heard that there was no pilot, these experts were afraid one by one, and an expert said: "Pure automatic driving is impossible, even drones can't do it, although drones are unmanned, but they also need people to control, flying is such an extremely rigorous thing, if no one participates, no matter how precise the machine and computer are, it is unreliable after all." ”

Zhang Wenhao sneered and said, "Let me tell you, as long as the machine and computer are high-end enough, then it will always be much more reliable than people!" ”

Speaking, Zhang Wenhao made a very simple analogy, said: "The vast majority of car accidents, are because of human problems, not machine problems, in the work, the number of times your computer crashes, never as many as the number of times you crash, you will take leave to strike because of various minor illnesses, but as long as your computer does not have congenital defects in software and hardware, there is no mistake in operation, it may not crash in a few years, but we will not rely entirely on computers and machines, sometimes, human participation is necessary, This time, though, we don't need anyone to be directly involved at all. ”

Seeing that none of these experts had the courage to board the plane, Director Liu said: "I don't dare to accept new things, and in the end I can only stay where I am, I believe that Dongchen's software and hardware must be more reliable than pilots, so you are willing to board the plane at will, but I will be the first to follow." ”

Several representatives of the military also expressed their willingness to board the plane to participate, and the remaining group of Beidou engineers struggled for a long time, and in the end, only half of them were willing to board the plane.

Zhang Wenhao didn't waste too much time, and immediately took these people to board the modified 737, in the cockpit, the positions of the captain and the co-pilot were empty, and several people crowded into the cockpit, wanting to see how this plane without a pilot completed automatic taxiing, entered the runway and completed take-off and landing.

Zhang Wenhao sat in the captain's position, and retrieved a set of data that had already been entered in the system on a control board in the center console, and said: "This set of data is all the coordinate information of our test airport, and the location of each hangar, every link line and runway has been entered, if I set it to prepare for take-off now, the plane will automatically enter the starting point of the runway and wait for takeoff." ”

Saying that, Zhang Wenhao called up another set of data, and said: "This set of data is the route data of the five-sided approach of the test airport, if I also call up this set of data, the plane will fly according to the route marked on this set of data after takeoff, until landing, and then, I can choose any hangar or parking stand as the taxiing destination, and the plane will drive to the designated position by itself after landing." ”

Everyone felt that this matter was very incredible, and Zhang Wenhao set the last data at this time, that is, where the plane should taxi after landing.

"The end of our flight is our starting point." Speaking, Zhang Wenhao explained: "I have input our current coordinate position and the direction information of the plane into the computer, and after the plane completes the flight, it will automatically taxi to the position we are now, and there will be no deviation in the direction of the nose of the aircraft."
