Chapter 1527: spark

According to the rules of the International Telecommunication Union, the orbit and signal frequency of satellite operation must be applied in advance before use, and the satellite must be launched into orbit and signal reception within 7 years after the application is approved, otherwise the relevant resources will be recovered. The rules follow " The principle of "first application, first acquisition, first launch, first possession".
Hua Xia still applied for the frequency band before the launch of "Beidou One". It was approved on April 17, 2000. The International Telecommunication Union allocated E1 (1590MHz), E2 (1561MHz), E6 (1269MHz) and E5B (1207MHz). This band is given to the Beidou satellite navigation experimental system, but this overlaps with some of the bands used or planned to be used by the Galileo positioning system!
The "Beidou No. 1" system was designed and manufactured to verify the feasibility of the entire system. Therefore, when it was built, considering the cost, it covered few frequency bands, only two core frequency bands, and had a low service life. And now 6 years have passed since the launch of the first star, and the two working stars have been scrapped. Even the backup star launched in 2003 has stopped working. In other words, at this time, no satellites actually occupy China. These working frequency bands!
Then, according to the rules, the International Telecommunication Union will withdraw these frequency bands at midnight on April 17, 2007. Since the EU has already applied for the
Galileo
system, the possibility of China Xia’s application being approved is almost zero!
Not to mention that these frequency bands are the most suitable frequency bands for satellite navigation systems. Even if it is assumed that changing to other frequency bands is technically operability, changing the main operating parameters of the entire system from the beginning will inevitably be a time-consuming process. It takes a long time and consumes a huge investment, because the entire system almost needs to be overturned and rebuilt!
For this reason, Huaxia at that time, it can be said that it was racing against the clock to launch its operations. First, it manufactured and launched a "Beidou-1" satellite at the fastest speed, seizing two of the core frequency bands, and leaving the future comeback. Cost; then, to develop and launch a full-band satellite of the "Beidou-2" system at the fastest speed, must be in time for the launch of the EU satellite, and must be before the deadline set by the International Telecommunication Union!
Especially for the next launch, not only need to catch up with the schedule, but also need to ensure that the success rate of the stars and arrows must be 100%, and no mistakes are allowed!
It was under such tremendous pressure that all the staff of China Aerospace Systems at that time created a miracle with wisdom, sweat and professionalism. The project was restarted in December 2006, and only 4 months later, the "Beidou 2" first star It was launched into space on April 14, 2007. After the orbit change and the final positioning, the monitoring hall received the signal from the satellite from 20,000 kilometers away from space and successfully analyzed it. It was already the evening of April 16. At 8 o'clock, only 4 hours are left before the frequency band applied to the International Telecommunication Union expires!
In that time and space, Tan Zhenhua, as a member of the technical support team of the 4014 Institute, participated in the satellite launch project throughout a certain satellite monitoring base. He still remembers the moment when the satellite signal came—all the staff couldn’t help but burst out. Warm applause, and the faces full of tears with excitement and excitement, some of them are gray-haired, some are young, but at that moment, their faces are full of glory and pride!
He still remembered that at the turn of the spring and summer of 2007, the chief instructor in charge of the entire operation was not the academician Chen Fangyun Chen in front of him, but a heroine Yang Hui. He even knew that if this Chen Fangyun was in front of him The academician reckoned that when the "Beidou" spark reached Yang Hui, it was already the third generation!
This is a great achievement that is enough to be included in the history of the new China's scientific development, and it has created a miracle in the field of engineering research. However, this miracle is not so much created by China's initiative, as it is forced by objective reality. , Then, is this history necessary to repeat itself in this time and space?
Obviously, Minister Zhang Jun, who is completely ignorant of all these events that have not occurred, Minister Mo Wenxiang who has retired, and Academician Chen Fangyun, the proponent of the project, all instinctively chose the safest way forward. They brought Tan Zhenhua into the partnership. However, in order to solve the imminent funding problem, it is also to solve the technical problems of many topics. Because Tan Zhenhua, he is not only the richest man of Chinese in the world, but there is no doubt that he is the most outstanding scientific and technological leader in the entire Chinese community. An arguable Chinese nationality!
He himself may not have many demonstrable inventions, but with his "golden fingers", the progress made by China in the field of basic science and engineering science in recent years can be seen almost everywhere. !
Since Tan Zhenhua has decided to invest in this project, it is obvious that he is not going to jump off the "big pit" of cooperation with the European Union. "A good fighter has no merit." Step by step and smooth success is his best. For the desired result, he believes in the technical strength and creativity of these Huaxia researchers. All he needs to do is to grasp the project process on the right track at the right time and at the right time.
This is the advantage of his knowledge of history!
Miguo, do you still want to sell us a GPS chip for civilian use at a price of US$120 per piece like another time and space?
(Historical prices, readers who are old enough can greatly recall the price of special car navigation systems that were once popular from the 1990s to the beginning of the new century.)
With this young master, let's dream!
With Beidou, the GPS system can only be a supporting role, so the price of the chip is US$1, which can’t be more!
It's great to have an open life.
The meeting on the "Beidou" system finally ended. Everyone who participated in the meeting got the results they wanted. The next important task was handed over to the project chief recommended by Academician Chen Fangyun, and the 58-year-old Fan Benyao this year He wants to complete the task of building the entire experimental system of the "Beidou 1" within 5 years. This is a huge challenge, and he is determined.
Fan Benyao will soon take over the spark passed by Chen Fangyun, become the second-generation "Beidouman" and embark on a magnificent journey. This is destined to end his career after drawing a perfect end, and Tan Zhenhua will enter. Another meeting room, to welcome his glory.
Still in the Ministry of Aeronautics and Astronautics, but this time it was changed to a big conference room. When Tan Zhenhua walked into this conference room accompanied by Minister Zhang, he was greeted with warm and protracted applause. , There were even a few unconscious guys who actually blew a loud whistle in public.
Wu Daguan, Meng Xiuzhen, Liu Daxiang, Zhang Enhe, Lu Guangjie, Ma Fengshan, Wang Qingping, Chen Yijian, Gu Songfeng, his teachers Song Wenhua and Guo Rongwei, etc. were all present, but the few stupid whistling boys were Yang Wei, Tang Changhong, Wu Guanghui...
Oh, it's so neat today!
