Super Copy of Great Power Technology

I clicked on the news and checked the content. It said that the fifth-generation Beidou system completed the launch of the last two satellites, with a positioning accuracy of 0.1 meters; speed measurement accuracy of 0.02 meters per second; and time synchronization accuracy of 10 nanoseconds; and it can provide communication and data services to million terminal users.

I didn't expect that the fifth-generation Beidou satellite system has evolved to such an extent. But isn't this exactly the dual-function satellite for positioning and communication that Qiao Ruida is looking for? It perfectly meets the requirements. Qiao Ruida immediately found several real photos of the fifth-generation Beidou satellite from the news, saved them in the album, and chose to copy them. Of course, the size of the satellite is too large. If one is made, the office will be blown up, so Qiao Ruida did not choose the copy location in the real world, but placed it in the dimensional space.

In order to avoid being disturbed, Qiao Ruida stood up and locked the office door. He lay back in his boss chair and controlled his consciousness to enter the dimensional space. Sure enough, in an open space in the space, he saw a huge satellite. If the solar panels were included, its wingspan was even more than 20 meters, which was a behemoth. It was quite difficult to stuff such a big guy into a fairing with a diameter of only 3.5 meters. Not only did the solar panels have to be folded, but the layout of some antennas and external equipment also had to be adjusted. What was more troublesome was that the frequency of the satellite's operation had to be changed.

Satellite radio frequency resources are important strategic resources and are a prerequisite for aircraft to enter, perceive and use space. According to international rules, satellite radio frequencies are limited natural resources shared by all mankind and are uniformly planned, supervised and managed by the International Telecommunication Union. The satellite in front of us is one of the fifth-generation Beidou navigation system, and the communication frequency used is the same as that of previous generations of Beidou systems. If it is launched directly into space, it will conflict with existing Beidou satellites, affecting communication stability or even making it impossible to work.

Qiao Ruida must find a way to change the communication frequency of this satellite to a completely new frequency and complete the frequency declaration work before it can be launched. In order to change the communication frequency, you must understand the design and working principle of this satellite. If someone else comes, even if it is an expert in satellite development, it will take a month or two to study the drawings and materials before it can be done. For Qiao Ruida, a cheating player, it is relatively simple. You only need to call up the photo of this satellite from the system album, and then use the analysis function. The next moment, a large number of drawings and materials will flood into your mind. After a few seconds, Qiao Ruida already knows all the structures and working principles of the satellite in front of him. To change the communication frequency, you only need to change some system source codes and replace a few parts. However, before making any changes, you must first find a frequency that no one is using and complete the frequency declaration before you can start.

After his consciousness exited the dimensional space, Qiao Ruida took out his mobile phone and called Cao Yifei, the general manager of Ruida Aerospace, and told him about the satellite communication frequency query and declaration.

"Boss Qiao, I'm afraid this matter is not easy to handle. According to what I know, if you want to apply to the International Telecommunication Union for the right to use a certain frequency, you must submit an application two years before the satellite is launched. There is still a lot of uncertainty as to whether it will be approved. If you want to get satellite communication frequencies in a short period of time, you can only apply to the national aerospace department. They have some reserve frequencies, and you can buy them for use as long as you spend a little more money. But if you do this, there are not many frequencies to choose from, and the communication effect is difficult to guarantee. Like what you said, the frequency suitable for global satellite positioning and satellite communications is probably difficult to apply for."

After all, Cao Yifei is an old aerospace man and has some understanding of satellite communication frequencies. He talked to Qiao Ruida about the difficulties involved.

"How about this, Manager Cao, you go to the national aerospace department and ask what frequencies they have for sale. Provide me with a list and I will see if there is anything that meets the requirements." Faced with this situation, Qiao Ruida was helpless. He just hoped that his luck would not be too bad and he could get a usable communication frequency.

Two days later, Cao Yifei handed a piece of printed paper with frequency numbers printed on it to Qiao Ruida and said, "Mr. Qiao, these are most of the satellite communication frequencies stored by the national aerospace department. There are several hundred of them in total. I don't know much about wireless communications, and I don't know whether these frequencies are good or bad."

Qiao Ruida took the printed paper and read through all the frequencies at a glance, and finally focused his attention on the three frequencies circled in red.

"1276.45 MHz, 1675.42 MHz, 2292.028 MHz, what are these three frequencies, and why are they circled in red?"

The red circle was marked by Cao Yifei. He knew the reason and quickly explained, "It is like this, Mr. Qiao. These three frequencies are said to be the backup frequencies applied for when the Beidou navigation system was first developed. Now that the Beidou system has been in operation for many years, the frequencies will basically not be changed, and these backup frequencies are no longer useful. This time, the people in the aerospace department heard that our Ruida Aerospace was going to develop commercial navigation satellites, so they took out these three frequencies."

"Well, these three frequencies are good. We must get them. And this, this, and this, we also need to buy them together. In the next few years, our Ruida Aerospace will launch many satellites and spacecraft. It is better to reserve a few more communication frequencies to be prepared." Qiao Ruida picked up a pen from the desk and drew circles on the printed paper, circling more than a dozen frequencies.

"Okay, Mr. Qiao, I will contact the aerospace department right away to discuss the purchase of frequencies."

After sending Cao Yifei away, Qiao Ruida was finally able to modify the communication frequency of the navigation satellite. He directly used the three backup frequencies of the Beidou system. Perhaps these three frequencies did not expect that they would be activated one day.

Time soon came to the end of August, and the new semester was about to start. My sister Qiao Ruixue, a freshman at Peking University, came to Beijing two days in advance. At that time, Qiao Ruida was in a meeting at the company, and it was Du Qingqing who drove to the train station to pick her up.

After get off work in the evening, Qiao Ruida drove back to the courtyard and met his sister Qiao Ruixue. After not seeing her for a month, the girl seemed to have grown taller, now over 1.7 meters tall, with longer hair, light makeup on her face, and a change of her student style to a more fashionable one. It seemed that his sister had initially completed the transition from high school student to college student, and had adapted well.

"Xiaoxue, have you passed your driving test?" Qiao Ruida asked.

"Of course! With my smart brain and developed limbs, a driver's license is easy for me to get." As she spoke, Qiao Ruixue took out a black notebook from her pocket and showed off proudly for a long time.

"Since you have a driver's license, you can drive this convertible sports car first. The sports car customized for you is still undergoing safety certification. It will take at least two or three months to get it on the road normally." Qiao Ruida took out a car key from his pocket and threw it to Qiao Ruixue. "Oh, that's great. From now on, I'm also a car owner, and it's a convertible sports car. Brother, isn't this your car? You gave it to me, what are you driving?" Qiao Ruixue jumped up with joy after getting the car key. As a novice driver who has just learned to drive, Qiao Ruixue is in the period of being most interested in vehicles, especially since this is a convertible sports car, and she can't be too happy.

"I'm your brother, the boss of a car factory, so you don't have to worry about not having a car to drive. You can go to my garage and see. There are more than a dozen cars of various kinds, including off-road, business, SUV, sedan, gasoline, electric, hybrid. Many cars are only driven a few times a year, and there is a thick layer of dust on them." He showed off a little in front of his sister, and it felt quite good.

"Then, when school starts the day after tomorrow, can I drive a sports car to school?" Qiao Ruixue is already imagining the scene of herself driving a convertible sports car along the shores of Peking University's Weiming Lake.

"If you are not afraid of being watched, you can drive to school. There are many luxury cars and sports cars in the parking lot at the entrance of Peking University. If this Roster sports car drives past, there may not be any onlookers."

"Why should I park my car outside the school? Can't I drive into the Peking University campus?" Qiao Ruixue asked with some confusion.

Qiao Ruida rolled his eyes and said, "Do you think Peking University is a public parking lot? Any car can enter. If you want to drive into the Peking University campus, you must have a Peking University pass issued by the Academic Affairs Office. Only faculty and students of the school can apply for this pass. However, the success rate of undergraduate applications is very low. Anyway, in three years of college, I have never seen an undergraduate student successfully apply for a pass."

"Is that so? Then we should park it at the main entrance. It will only take a few more steps to get the bike. We can also buy a folding bike later to commute around campus."

Two days later, when the new students of Peking University registered, Qiao Ruixue did not drive to the school by herself, but Qiao Ruida and Du Qingqing drove a Ruida MPV to take her there. One reason for doing so was that Qiao Ruixue brought too much luggage, all kinds of clothes, babies, toys, books, filled two 28-inch large suitcases, and the half-castrated trunk of the convertible sports car could not fit them all. Another reason was that it was Qiao Ruixue's first time to Peking University after all, she was unfamiliar with the place, and there were so many evil seniors eyeing her covetously, Qiao Ruida was really worried about her going to school alone. It would be better to bring his girlfriend along, and the two of them would send his sister to school together, so that everyone could feel at ease.

Today is the day for new students to register. The main gate of Peking University is particularly lively. Buses picking up new students are constantly coming in and out, and a large number of new college students and parents who come to send their children back from the station are also coming. There are also students like Qiao Ruixue who take private cars or taxis to the Peking University campus. Most of them are locals in Beijing or people from cities around Beijing.

Qiao Ruida parked the car in the parking lot outside the school gate, and then the three of them walked into the school gate together with their luggage. Qiao Ruixue and Du Qingqing were both beautiful school girls. If they appeared alone, they could attract the attention of most male compatriots. Now that they appeared at the same time, their lethality was doubled. The eyes of all male creatures in the audience were attracted to them, including some girls, who couldn't help but look at them a few more times.

Some senior students who were tasked with welcoming the new students were quite excited to approach Qiao Ruixue and chat with her when they saw her. However, when they saw Du Qingqing and Qiao Ruida accompanying Qiao Ruixue, they gave up the idea in disappointment. Qiao Ruida and Du Qingqing, a young couple, were very well-known on the Peking University campus. They were the richest man in the country and a model of entrepreneurship. All Peking University students knew them. The new students who were accompanied by Qiao Ruida and Du Qingqing to school were probably not simple people, so they should not approach them and embarrass themselves.

"This is the Peking University campus. The environment is so nice, with flowers and big trees everywhere, and so many quaint buildings. Studying and living in such an environment is simply a pleasure!" Qiao Ruixue said with emotion as she looked around.

"This is just the main entrance, and the scenery is just so-so. The most beautiful places in Peking University are by the Weiming Lake and near the Boya Tower. When I have nothing to do in the afternoon, I'll take you there to have a look and take some photos." Du Qingqing took Qiao Ruixue's hand and walked directly to the May Fourth Playground inside the school. The registration points for freshmen of various departments were all concentrated on the playground.

The next step was to go through the formalities. Qiao Ruixue took her admission letter and ID card to the department reception to register, then went to the settlement center in the fourth teaching building to pay the fee, then returned to the reception to get the dormitory key and campus card, and then went to the second teaching building to get camouflage uniforms, bedding and other things. Even with the two veterans Qiao Ruida and Du Qingqing accompanying her, it was already two hours later when Qiao Ruixue went through all the formalities and finally arrived at the dormitory.

Qiao Ruixue's luck was not very good. The dormitory she was assigned to was in an old building. There was no elevator inside, so she could only climb the stairs. Fortunately, today was the day for the new students to register for the new semester, and the boys were allowed to enter the girls' dormitory building as an exception. Qiao Ruida now became a luggage porter. He dragged the two large suitcases to the sixth floor by himself.

When the three of them arrived at Qiao Ruixue's dormitory, there was already a girl and two parents inside. Judging from their clothes, they should be Tibetan compatriots.

"Hello, my name is Qiao Ruixue, and I'm from Beihe Province. What's your name?" Qiao Ruixue walked over and greeted the dark-skinned girl.

"Hello, I'm Gesar Laze from Mongolia Province, nice to meet you." Gesar Laze spoke Mandarin very well, with almost no local accent.

The two girls chatted while packing their things and quickly got to know each other. Qiao Ruida also tried to speak a few words to Laze's parents, but it was a bit difficult to communicate. Their Mandarin was awkward and often failed to express their meaning. (End of this chapter)
