When the helicopter started to take off, everyone discovered how powerful the handheld Dongchen positioning terminal was. The helicopter's own altimeter kept increasing in feet, and Dongchen's positioning terminal was
The altitude sensitivity increases in centimeters, and in addition to displaying the current altitude, the terminal can also calculate the helicopter's ascent speed at this moment by calculating the alternation of coordinate points within a certain period of time.
A bunch of Beidou system experts were dumbfounded, but the military people were very excited. Good guys, if this set of things is installed on an airplane and the data from this system is used to command the airplane to perform automatic driving, then
The accuracy of this kind of automatic driving will far exceed that of a pilot!
The helicopter climbed to an altitude of about a thousand meters above sea level. Zhang Wenhao said: "The handheld terminal also has a function, which is route recording. At any time, as long as you turn on the recording function, the terminal will record your most accurate three-dimensional movement route, including the plane.
Changes in location and altitude. Since we have added Dongchen's unique processing chip to the handheld terminal, the terminal can calculate such dense coordinate points very quickly and accurately. If you use this set of terminals in the future
If applied to the three armies of the sea, land and air force, I can ensure that you know the location and movements of all combat vehicles, ships and aircraft equipped with this terminal."
An Air Force engineer asked: "How do we collect statistics on such a huge terminal? Will Dongchen open the function of real-time sharing of coordinates?"
Zhang Wenhao said calmly: "We will give the military a special authority. At that time, we will provide the military with a 'management backend'. All Dongchen positioning modules installed on the military's weapons and equipment will be included in the management backend."
controlled objects, so that when you enter the background, you can see the real-time dynamics of individual, partial or even all controlled objects.”
With that said, Zhang Wenhao added: "If the military wants to upgrade its drones, Dongchen can provide an automatic control system based on Dongchen's positioning system. At that time, you only need to specify any target and then set
Both the task and the automatic control system can command the drone to execute it accurately."
The military representative was so excited that he went crazy, and blurted out: "When will such a system and enough terminals be put into practical use?"
Zhang Wenhao said: "One month? We have now started to produce terminal modules. We only need to wait for all our satellites to be launched into orbit, and when we achieve global coverage, the entire Dongchen positioning system, whether for civilian or military use, can be
Start immediately."
The military representative counted on his fingers and exclaimed: "From the launch of the first satellite to full practical application, the entire process only takes less than two months? Isn't this too fast?"
Zhang Wenhao smiled slightly and said: "This is Dongchen speed. When a new technology is born, it must be pushed into the practical application stage as quickly as possible. Otherwise, a system using technology from twenty years ago will fail."
Twenty years, twenty years later it was finally built, but as soon as it was built it was already outdated.”
This was obviously meant for the Beidou experts, which also made the experts who had some doubts about the Dongchen positioning system blush in the face.
It is incredible to build a global positioning system in two months. What's more, the technology used in the system itself is at least decades ahead of Beidou. Once Dongchen's system is completed
Global coverage, then Beidou can be officially laid off. What is regrettable is that Beidou has not yet completed global coverage!
Immediately, Zhang Wenhao added: "Dongchen positioning system is not just for simple positioning services, because the positioning accuracy is extremely high and very stable. Therefore, I think this system can be used in many aspects in the future.
Extended, for example, if each high-speed train on a high-speed railway is equipped with Dongchen's positioning system, then we can develop a dispatching system based on Dongchen's positioning system for the railway department. The position and speed of the train,
The distance between the front and rear cars will be displayed extremely accurately in the dispatch system."
"If the military needs more precise satellite guidance, then we can also open guidance services to the military. All your needs for precise positions can be met from Dongchen."
For these so-called experts and military engineers, Zhang Wenhao was not prepared to let them participate in the system test from the beginning. All Zhang Wenhao's purpose was to use his own method to demonstrate the excellence and incompetence of the Dongchen positioning system.
match.
Helicopters kept flying around the airport, and these experts also saw from the terminals in their hands that the terminals continued to record the longer and longer flight trajectories of the aircraft, and indeed, as Zhang Wenhao said, it was a three-dimensional trajectory.
And it's almost exactly the same.
However, this is just a demonstration to demonstrate the accuracy and extended functions of the Dongchen positioning system. Regarding how to demonstrate the application of the Dongchen positioning system at a higher level, Zhang Wenhao can put the second test at nine o'clock in the evening.
This test used a modified Boeing 737. The positioning system, altitude, ground speed, airspeed and other data sources of this Boeing 737 were all modified. All data were processed by the Dongchen positioning system.
Provided, the autopilot function of the aircraft has also been upgraded and matched with Dongchen's positioning system. It can be said that the positioning and autopilot system currently equipped on this aircraft is what Zhang Wenhao will actually apply in Dongchen himself in the future.
A complete set of technologies on board the aircraft.
The so-called autopilot of today's civil aviation airliners is, to put it bluntly, nothing more than locking the coordinates and allowing the aircraft to fly itself in the air after taking off and entering the cruising altitude. However, when it comes to true automatic takeoff and landing, this is basically the same as wishful thinking.
However, Zhang Wenhao not only wanted this 737 to take off and land automatically and fly automatically, but also simulated the worst situation, that is, a situation with no visual status at all.
The entire airport fell into darkness, and the guidance lights on the tower, buildings, and runways were all turned off. If you stood at a high enough place and looked at the airport, people would even feel that it was a blank area. This is also the extreme badness that Zhang Wenhao pursues.
Sight distance, to put it bluntly, means there is no sight distance at all.
Zhang Wenhao invited Director Liu and a group of more than a dozen people and said: "This aircraft will not be equipped with a pilot. From rolling out of the hangar, to entering the runway through the link line, taking off, flying and finally landing, everything is controlled by the autopilot system in cooperation with Dongchen
The positioning system will be used to complete it. I wonder which of you dares to board this plane with me?"
When they heard that there was no pilot, each of these experts looked frightened. One expert said: "Pure autonomous driving is impossible. Even drones can't do it. Although drones are unmanned, but...
It also requires people to control it. If there is no human participation in something as rigorous as flying, no matter how sophisticated the machines and computers are, they will ultimately be unreliable."
Zhang Wenhao sneered and said, "Let me tell you, as long as machines and computers are high-end enough, they will always be much more reliable than humans!"
As he spoke, Zhang Wenhao made a very simple metaphor and said: "The vast majority of car accidents are caused by problems with people, not machines. At work, your computer will never crash as often as
Your computer crashes a lot, and you take time off work due to various minor ailments. But as long as your computer has no inherent defects in software or hardware and no operating errors, it is possible that it will not crash within a few years.
, but we will not rely entirely on computers and machines. Sometimes, human participation is necessary, but this time, we do not need anyone to directly participate at all."
Seeing that none of these experts had the guts to board the plane, Director Liu said: "If you dare not accept new things, you often end up staying where you are. I believe Dongchen's software and hardware must be more reliable than the pilots, so
, you are free to board the plane if you wish, but I will be the first to follow."
Several representatives of the military also expressed their willingness to board the plane to participate. The remaining Beidou engineers struggled for a long time, and in the end only 50% of them were willing to board the plane.
Zhang Wenhao didn't waste too much time and immediately took these people on board the modified 737. In the cockpit, the captain and co-pilot's seats were empty. Several people crowded into the cockpit and wanted to take a look.
How does this plane without a pilot complete automatic taxiing, enter the runway and complete takeoff and landing?
Zhang Wenhao sat in the captain's position, retrieved a set of data that had already been entered into the system on a control panel on the center console, and said: "This set of data is all the coordinate information of our test airport. Every day
A hangar, each link line and the location of the runway are input. If I set it to prepare for takeoff now, the aircraft will automatically enter the starting point of the runway and wait for takeoff."
With that said, Zhang Wenhao called up another set of data and said: "This set of data is the final approach route data of the test airport. If I also call out this set of data, the aircraft will follow this set of data after takeoff.
I fly the route marked on the data until landing, and then I can choose any hangar or parking space as the taxiing destination, and the aircraft will drive to the designated location after landing."
Everyone thought this thing was incredible, but Zhang Wenhao set the last data at this time, which was where the plane should taxi after landing.
"The end point of our flight is our starting point." Zhang Wenhao explained: "I entered our current coordinate position and the aircraft's direction information into the computer. After the aircraft completes its flight, it will automatically taxi to where we are now.
At the position, and even the direction of the aircraft nose will not deviate in any way." (To be continued. Please search Piaotian Literature, the novel will be better and updated faster!)
