Why does China spend huge sums of money on Beidou?In-depth revelation of the past and present life of GPS!
A topic I talked about with my friends during the Chinese New Year about how drivers used to drive as usual without navigation, and now we are lucky to have GPS. This makes people wonder why China is investing in the Beidou system when GPS is so powerful
First of all, let's understand the origin of GPS. Although we equate GPS with navigation, in fact, GPS is the abbreviation of Global Positioning System, established in 1958 by the United States to provide emergency communications, intelligence monitoring and nuclear explosion detection services for the military. Due to its military background, GPS was once controlled by the military, and signal jammers were added to the system, reducing the precise positioning of civilian use.
However, with the launch of the GLONASS system in Russia and becoming a competitor of GPS, the United States has given up signal interference for civilian GPS in order to maintain its civilian market share. Despite this, there is still a difference in accuracy between military GPS and civilian GPS, with military GPS being millimeter-accurate and supporting wide-angle military strikes.
So, the question is, since there is a civilian GPS, why do you need the Beidou system?This is a matter of technical cards and autonomy. Although the GPS of the United States is powerful, it is not in our own hands after all, and we cannot control it independently. Once a risk arises, we can only bear the consequences ourselves.
Back in 1933, a cargo ship in China was traveling at sea, but it drifted for more than 30 days because the United States shut down the GPS navigation service in the sea area. This incident has made us deeply aware that without the satellite positioning system, we will be swayed by others, which is intolerable.
As a result, China decided to develop its own satellite positioning system. Although it was difficult to get started, in 2007, we officially started the construction of the Beidou system, and it took five years to complete the layout of the Asia-Pacific region. Today, the Beidou system has become the pride of China's science and technology, providing reliable positioning services for civilian and military fields.
The advantage of the Beidou system is that it is latecomer, such as the two-way contact system, which is more stable than the one-way system. In disaster relief, the Beidou system has shown its importance. However, although Beidou is not inferior to GPS in accuracy and reliability, it still faces some doubts, such as the incident of a female college student at Tsinghua University deciphering Beidou encryption.
In fact, what this student deciphered was only civilian **, and military ** was not deciphered. The core of Beidou is in the military, and once military technology is leaked, it may pose a threat to the military. Therefore, it has become particularly important to educate and train clusters of scientists in science.
With the improvement of China's scientific and technological strength, we no longer need students to seek advanced scientific knowledge abroad. The country's in-depth promotion of science education will help train more scientists and no longer rely on studying abroad.
The rise of the Beidou system is a microcosm of China's independent innovation in science and technology. Despite some challenges, we firmly believe that the Beidou system is strong and stable, and is a symbol of China's scientific and technological strength. In the future, with the continuous progress of technology, the Beidou system will play a more important role in the field of global positioning.
Beidou System: The pinnacle of independent technology
This paper provides an in-depth analysis of the reasons behind China's investment in the BeiDou system, and reviews the evolution of the global positioning system. In vivid and interesting language, the article reveals the rise of the Beidou system as one of the representatives of China's science and technology, which makes people proud of China's great progress in the field of science and technology.
First of all, the article introduces the topic with examples of drivers using navigation in the past and present, which arouses readers' thoughts on the change and progress of technology. Through the introduction of the military background and development process of GPS, readers deeply realize that the development of science and technology is closely related to China, and they also have a better understanding of China's determination to independently develop the Beidou system.
The author connects the development process of the Beidou system with clear clues, from the GPS of the United States to the rival GLONASS system of Russia, and then to the Beidou system of China. Through this process, readers gain a deeper understanding of the complexities of GPS and the wrestling of countries in the field of science and technology.
Guided by a clear question, the article raises a question worth thinking about for readers: Why does China spend huge sums of money on the Beidou system?And through the retrospective of historical events, readers have a clearer understanding of this issue. The article cites the incident of a Chinese freighter being drifted, vividly illustrating that countries without a satellite positioning system will be subject to others and pose a potential threat to ***.
In the second half of the article, the author takes the advantages of the BeiDou system as a starting point, focusing on the role of the BeiDou system in disaster relief and its wide application in the civilian and military fields. At the same time, the author analyzes the doubts faced by the Beidou system, highlighting the importance of military technology and the guarantee of the first class.
Finally, the article provides a clear direction for the country's independent innovation in science and technology with its appeal to the training of scientists and science education. By linking science education with the construction of the Beidou system, readers are full of expectations for the country's future development in the field of science and technology.
In general, this paper uses vivid and interesting language and clear logical structure to deeply interpret the reasons and significance of China's investment in building the Beidou system, which not only gives readers a deeper understanding of the process of scientific and technological development, but also arouses the attention and thinking of national independent scientific and technological innovation.
