The news is reporting the shocking news that Dongchen and Airbus have reached an acquisition intention, and at this time, Zhang Wenhao has put down a stone in his heart, although now he has sent someone who has not yet evaluated all the assets of Airbus, but it is impossible for anyone in the world to pay more money than himself to acquire Airbus, even Raymond does not dare to rob himself, all those who are involved in aircraft manufacturing or interested in aircraft manufacturing are afraid of a problem, that is, Dongchen Aviation Engineering in Zhang Wenhao's hands.

The acquisition of Airbus is a relatively long process, the evaluation is done, and then the Airbus people reach an agreement, this process will take more than a month, such a large acquisition, if it is a normal enterprise, just the tug-of-war between the two sides will have to last for more than half a year, but in Zhang Wenhao's place, the process of the tug-of-war is completely omitted, because he doesn't care about the money, so how about Airbus when he sells himself? It doesn't affect you.

When Zhang Wenhao got rid of Airbus's big idea, the seven positioning satellites launched by China for Dongchen have also been launched into the sky, and the launch of the United States and Australia has also begun to enter the countdown, and in a maximum of 20 days, all the satellites can be launched in place at one time.

However, the test of Dongchen's stereoscopic satellite positioning system does not need to wait for all the satellites to go into the sky before proceeding, because seven satellites have been put into orbit, and these seven satellites will envelop most of the Asia-Pacific region.

The state and the military attach great importance to this positioning system, and when the seven satellites were put into orbit, Officer Liu went to China Shipping in person. Meet Zhang Wenhao at Dongchen Aviation.

This. Director Liu led a team of experts composed of more than ten people. Of these dozen people, six of them are information technology engineers of the navy, land and air force, and the rest are all core engineers of the Beidou satellite positioning system.

Zhang Wenhao has already prepared a number of test terminals. Among them, there are handheld terminals, terminal modules embedded in mobile phones, vehicle-mounted, airborne and ship-borne terminals.

Among them, the function of the airborne terminal is the most powerful, followed by the shipborne and the vehicle-mounted again, the handheld terminal is relatively weaker, and the function of the mobile phone terminal is weakened more seriously.

However, all terminals have several basic functions, namely: plane satellite positioning, stereo satellite positioning, satellite speed measurement three core functions.

When Zhang Wenhao met with Director Liu and his party of more than a dozen people, Secretary Liu asked with great interest: "Wenhao, are the relevant work of the test ready?" ”

Zhang Wenhao said indifferently: "The main content of this test is very simple, in fact, it is nothing more than the test of so many functions and indicators. And, our tests. Unlike your usual tests, all of you are subject to our arrangement, you are a visitor to the test, not a direct participant, and do not have the right to make any changes to the content of the test. ”

Director Liu hurriedly said: "That's natural, we mainly came with the attitude of visiting and learning. ”

Zhang Wenhao nodded and said, "The first test, let's go to the test airfield, and start from there." ”

A group of people took a bus directly to the airport, and the airport had already been prepared at this time, Zhang Wenhao rented a helicopter that was allowed to carry 22 people, and at this moment, the plane was parked on the apron of the airport, waiting for Zhang Wenhao's arrival.

Zhang Wenhao got out of the car with more than ten people, and said: "Dongchen's positioning system, on the whole, we have completed the detection of the area currently covered, and at present, our seven satellites, covering most of the Asia-Pacific region, have achieved no dead ends in the coverage area, and there are no blind spots in the region, so you can rest assured about the coverage and stability, and I will not demonstrate this to you." ”

An engineer of the Beidou system frowned and asked, "How long has your satellite been up?" Have you already done all of the coverage of half of the Asia-Pacific region? Do you know how many geographical blind spots there are in the Asia-Pacific region? Have you monitored all those blind spots? ”

Zhang Wenhao frowned, and said in his heart, where the hell did you come to study, so much nonsense?

He said angrily: "Dongchen positioning system, which is completely different from your positioning system, is that our satellite can accurately project all the coordinate points to each location where the positioning signal can be transmitted and make real-time feedback on the projection situation, we don't have to go out to find the blind spot, but can directly see where the blind spot is, understand?" ”

Saying that, Zhang Wenhao was afraid that he would not understand, and continued: "We have countless coordinate points less than one centimeter apart in the plane and three-dimensional space in the coverage area, if any place is not covered by the coordinate points, our satellites themselves can distinguish it, so we can immediately know how many irreversible blind spots are there in the coverage area, and how many blind spots do you have now?" Do you want me to go back and give you a copy of the most complete blind spot information? ”

The man was immediately dumbfounded, and his face was flushed by Zhang Wenhao, but he couldn't say a word.

Zhang Wenhao said angrily at this time: "Dongchen positioning system, every coordinate point is very clear, when you get on the plane, you will be able to see what is called ultra-high-precision positioning system, even the instrument you have always trusted is far from comparable!" ”

The group got on the helicopter, and everyone who boarded the helicopter got a small box given by the staff, which contained a set of Dongchen's handheld positioning terminal, and after getting on the plane, Xiao Zheng said: "You guys now open the handheld terminal and take a look at the current location data first." ”

A group of people hurriedly opened the positioning terminal issued by Dongchen, and after opening, the real-time coordinates and altitude of this place appeared on the LCD screen.

Xiao Zheng said: "Before the plane takes off, you first try the positioning accuracy of the positioning system in the plane." ”

When these people look at the positioning system, they find that the positioning coordinates are much longer than the general latitude and longitude, which shows that the positioning system of Dongchen is more accurate than the traditional latitude and longitude coordinates, and when someone accidentally moves the positioning system in their hands, they find that the coordinate information on it will also change if they move slightly.

"The accuracy of this positioning and the speed of coordinate update are also too fast!" A Beidou engineer exclaimed, "Almost every time you move, the coordinates change. ”

Zhang Wenhao said indifferently: "If you can't use such a high accuracy in actual use, you can enlarge the accuracy setting, in addition, you can turn on the real-time speed measurement function in the terminal, and the terminal will calculate the most accurate real-time movement speed according to the change of coordinate points and the time it takes." ”

Everyone was amazed and began to try, and sure enough, one of them couldn't help but say: "The speed of my arm just now is 2.341 kilometers per hour. ”

Zhang Wenhao said: "If you throw it out, the positioning system itself can record the most accurate parabola and the fall process, if you use it on the plane, you can see the most accurate flight trajectory of the plane in flight, and this information will also be transmitted to the black box by the facts, so that once the plane crashes, you can restore the entire fall process of the plane according to the flight trajectory data in the black box." ”

Speaking, Zhang Wenhao pointed to an altimeter added in the cabin, and said: "This altimeter is an additional addition from me, the same as the altimeter used by the helicopter itself, and the same as the altimeter used by most aircraft, but its smallest unit is one foot, after the plane takes off, you can use the altitude data that appears on the terminal to compare it with the data on this altimeter, and see whether the instrument is more accurate, or the positioning system is more accurate." ”

"It must be the most accurate positioning system." An engineer said: "I put the positioning terminal on my lap, showing that my current altitude is 45.54 meters, I hold it in my hand at an altitude of 45.82 meters, and the positioning accuracy of the altitude has also reached the standard of one centimeter, this positioning system is really powerful!" Never heard of a positioning system that can also seem 4D stereoscopic. ”

Zhang Wenhao said indifferently: "It has many other auxiliary functions, for example, it can not only give your plane movement speed, but also give your altitude movement speed, so that it can more accurately record the aircraft's climb speed, the aircraft's climb trajectory, and even, can be used as a barrier for the aircraft to take off and land without a field of vision." ”

The people around them were surprised, they didn't know Dongchen's positioning system, and they didn't know how powerful this positioning system was, and Zhang Wenhao said at this time: "Our coordinates are three-dimensional, that is to say, when we mark a point, we will also mark the height of this point, such as the runway not far away, we take an intermediate point at the end of each end of the runway, and then input these two coordinates into the terminal, and the terminal will automatically connect the two points into a line, this line, It is the absolute centerline of this runway, because our positioning accuracy is less than one centimeter, so even if the airport and the runway do not have any actual field of vision, but through the simulation of the airborne positioning system on the display screen, the accuracy of its simulated field of view is much higher than that of the naked eye and other existing equipment, pilots can even use this system to let the aircraft take off and land in the absolute centerline, not only the position of the entire runway is well known, how high the landing gear is from the runway ground, can be clearly displayed, Even if the landing gear is still one centimeter away from the runway floor, it can accurately identify and warn.
