C423 Dong Chen Gps System(part Ii)
The Big Dipper System experts were stunned, but the military people were excited. Good fellow, if this thing were to be installed on the helicopter... And with the data from this system to command the plane to operate on its own, then the precision of this autopilot... It will far exceed the pilot!
The helicopter rose to a height of about 1,000 meters above sea level. Zhang Yunfeng said, "Holding the terminal has another function, which is to record the route, no matter the time. As long as you open the recording function, the terminal will record your most precise three-dimensional movement route. This includes the change in the plane position, the change in altitude, and because we have added the processing chip unique to Dong Chen into the handheld terminal. Therefore, the terminal's calculation speed for such a dense coordinate is very fast and precise. In the future, if you use this terminal on the Navy, Air, and Air Forces, then... I can guarantee that you know the location and movements of all the chariots, warships, and planes that have this terminal installed. "
An Air Force Engineer asked: "How do we calculate such a huge terminal? Will Dong Chen open the real-time coordinate sharing function? "
Zhang Yunfeng said indifferently, "We will give the military a special authority. At that time, we will provide the military with a "management background." All military weapons and equipment will be equipped with Dongchen GPS modules, which will be under the control of the management background. This way, when you enter the backstage, you will be able to see the real-time movements of individual or even all controlled targets. "
Zhang Yunfeng said, "If the military wants to upgrade their drones, Dongchen can provide an automated control system based on the Dongchen GPS system. At that time, you only need to select any target and then set the mission. The automated control system can command the drones to execute the mission precisely and accurately. "
The military representative was so excited that he almost went crazy. He blurted out, "When can such a system and enough terminals be put into practical use?"
Zhang Yunfeng said, "One month? We have already started to produce terminal modules. We just need to wait for all our satellites to be launched into orbit, and wait for us to achieve global coverage. The entire Dongchen GPS system, be it civilian or military, can be immediately activated. "
The military representative counted with his fingers and exclaimed, "From the launch of the first satellite to the full application, the whole process only takes less than two months? Isn't this too fast?"
Zhang Yunfeng smiled and said, "This is Dong Chen's speed. A new technology was born. We must push it to the practical stage as fast as possible. Otherwise... A system was built 20 years ago with technology from 20 years ago... 20 years. Then... It was finally built. It was just built, but it was already outdated."
These words were obviously meant for the experts of Big Dipper. This also made the experts who initially had doubts about Dong Chen's GPS system turn red in the face.
In two months' time, a global GPS system was built. This was already unimaginable, not to mention... The technology used by the system itself was at least several decades ahead of the Big Dipper. Once Dong Chen's system completed the global coverage, the Big Dipper would be officially dismissed. The hateful thing was that the Big Dipper had yet to complete the global coverage!
Then, Zhang Yunfeng said again, "Dong Chen's GPS system is not just to satisfy the simple function of GPS. Because the accuracy of GPS is extremely high and very stable. Therefore, I think this system can be expanded in many aspects in the future. For example, if every train on the high-speed railway is equipped with Dong Chen's positioning system. Then, we can develop a distribution system based on Dong Chen's GPS system for the railway department. The location of the train, its speed, and the distance between the front and back of the train will be displayed very precisely in the deployment system. "
"If the military needs more precise satellite guidance, we can also open up guidance services to the military. All of your needs for precise location can be met by Dongchen."
Regarding these so-called experts and military engineers, Zhang Yunfeng had never planned to let them participate in the system test from the very beginning. Zhang Yunfeng's goal was to use his own method. He wanted to demonstrate the excellence and incomparable of Dong Chen's positioning system.
The helicopter kept flying around the airport, and these experts also saw the terminal in their hands. The terminal kept recording the flight trajectory of the helicopter that was getting longer and longer, and it was really as Zhang Yunfeng had said. It was a stereotypical trajectory, and it was almost exactly the same.
However, this was only a demonstration of the accuracy and extension function of the Dongchen GPS system. As for how to show the application of Dongchen GPS on a higher level, Zhang Yunfeng could put the second test at nine o'clock in the evening.
This time, the test used a modified Boeing 737. This Boeing 737 GPS system, altitude, earth speed, and other data sources were all modified. All the data was provided by the Dongchen GPS system. The airplane's autopilot function was also upgraded. It also matched with the Dongchen GPS system. It could be said that... This plane was currently equipped with the GPS and autopilot system. It was the full set of techniques Zhang Yunfeng wanted to use on Dong Chen's own plane in the future.
To put it bluntly, the so-called autopilot of the Civil aviation aircraft was nothing more than after taking off and entering the cruise height. Locking the coordinates, the plane would fly by itself in the air. However, talking about the real automatic landing and landing was basically a pipe dream.
However, not only did Zhang Yunfeng want this 737 to fly on its own, he also wanted to simulate the worst case scenario. In other words, there was no visual condition at all.
The entire airport fell into darkness. The lights on the tower, the buildings, and the runway were all turned off. If one stood high enough and looked at the airport, they would even think that it was an empty area. This was also the extreme range of vision that Zhang Yunfeng pursued. To put it bluntly, there was no distance at all.
Zhang Yunfeng invited Director Liu and a dozen or so people and said, "This plane does not have pilots. From the time it is pushed out of the hangar, from the connecting line to the runway, the takeoff, the flight, and finally the landing, all of these are done by the autopilot system and Dong Chen's GPS system. I wonder who among you dares to board this plane with me? "
Once they heard that there were no pilots, these experts all revealed looks of fear. One. One of them said, "It's impossible to drive by pure autopilot. Even drones can't do it. Although drones are unmanned, they also need people to operate them. Flying is a very rigorous thing, if no one is involved, no matter how precise the machines and computers are, they are still unreliable. "
Zhang Yunfeng sneered and said, "Let me tell you, as long as the machine and the computer are high-end enough, it will always be more reliable than humans!"
As he spoke, Zhang Yunfeng made a very simple metaphor. He said, "Most of the accidents were caused by human problems. It was not because there was a problem with the machine. At work, the number of times your computer shuts down will never be as many as the number of times you shuts down. You will take a leave of absence because of various minor ailments, but as long as your computer doesn't have the congenital defects of software and hardware, and doesn't think that the operation is wrong... It might not shut down for a few years, but we also won't completely rely on computers and machines. Sometimes, it is necessary for people to participate. But... This time, we don't need anyone to directly participate. "
Director Liu saw that these experts didn't have the courage to board the plane, so he said, "If they don't dare to accept new things, they can only stay at the same place in the end. I believe that Dong Chen's software and hardware are more reliable than the pilots. So, it's up to you whether you want to board the plane or not, but I will be the first one to follow. "
A few representatives from the military also expressed their willingness to board the plane and participate. The remaining Big Dipper engineers struggled for a long time, but in the end, only 50% of them were willing to board the plane.
Zhang Yunfeng did not waste too much time. He immediately brought these people to board the modified 737. In the cockpit, the captain and deputy captain's seats were empty. A few people squeezed into the cockpit to take a look at the plane without a pilot. How exactly could it slide, enter the runway, and complete the landing?
Zhang Yunfeng sat in the captain's seat and adjusted a set of data that had been recorded in the system on a control panel of the central console. He said, "This set of data is all the coordinates of our test flight airport. Every hangar, every connecting line, and the location of the runway have all been input. If I set it to take off now, the airplane will automatically enter the starting point of the runway and wait for takeoff"
As he spoke, Zhang Yunfeng pulled up another set of data. He said. : "This set of data is the data on the route from the five airports to the nearest route. If I bring this set of data out as well, the plane will fly according to the route marked on this set of data after takeoff. After landing, I can choose any hangar or parking spot as my destination. After landing, the plane will fly to the designated location on its own. "
Everyone felt that this matter was very inconceivable. At this time, Zhang Yunfeng set the last data, which was where the plane would glide to after landing.
"The destination of our flight this time is our starting point." After saying that, Zhang Yunfeng explained, "I have entered our current coordinates, location, and direction information into the computer. After the plane has completed its flight, it will automatically glide to where we are now. Besides, there won't be any deviation from the direction of the nose of the plane. "
