On what GPS did China build the strongest positioning system in the world?

China is a developing country. In the process of continuous development in these years, China's science and technology has become more and more powerful. China has also made great efforts to develop science and technology. Today, China occupies a very important position in the world and has made a major breakthrough in science and technology. The achievements made have made countries around the world look at China with new eyes.

A long time ago, before our country mastered the core technology, our country relied heavily on foreign technology, but there was no free lunch in the world, and no country would help you without hesitation. Driven by interests, some countries will monopolize technology. America's GPS was once the most powerful positioning system in the world, and many countries relied on it. The United States has also benefited greatly from GPS. The United States has always been called the world hegemon in the world, so the United States has used GPS for hegemony many times in the world.

1993, when did the Galaxy incident take place in China, China? Galaxy? As an ocean-going container liner engaged in normal international commercial shipping, it set sail from Tianjin Xingang, stopped at Shanghai, Hong Kong, Singapore and Jakarta successively, and carried 782 containers to Dubai, Dammam and Kuwait. Originally, this was a normal commercial shipping.

But the United States suddenly stepped in and claimed? Galaxy? Have banned chemicals, and as a reason to China? Galaxy? Although China didn't want to ignore the unreasonable troubles of the United States, the United States took a tough stance and sent naval vessels and planes to confront it. Galaxy? The two sides were deadlocked for a long time, and then the United States cut off the GPS signal, resulting in? Galaxy? Unable to navigate, unable to move forward, finally? Galaxy? Wandering at sea for 33 days.

Because? Galaxy? Wandering at sea for too long also faces the problem of lack of materials. Finally, in desperation, China let the United States board the ship for inspection. It turns out? Galaxy? There were no prohibited items, and afterwards, the United States remained tough and refused to apologize. This incident has taught the people of China a lesson, and they are determined to develop our own technology. In order to have a longer-term development, we still have to master the core technology. Therefore, China decided to develop Beidou satellite navigation system to get rid of the dependence on GPS and not be controlled by others.

1994, China started the construction of Beidou-1 system. In 2000, two geostationary orbit satellites were launched, and the system was completed and put into use; Three geostationary orbit satellites were launched in 2003; In 2004, the construction of Beidou II system was started; In 2009, the Beidou-3 system was started; In 2020, the last global networking satellite of Beidou-3 will be launched in xichang satellite launch center.

The successful launch of the 55th navigation satellite Long March 3B of Beidou system means that the deployment of Beidou-3 global satellite navigation system constellation is fully completed.

China's Beidou satellite navigation system has become the fourth largest navigation system in the world after American GPS, European Galileo system and Russian GLONASS system, but among these four navigation systems, only GPS can compete with China's Beidou, because the Russian GLONASS satellite navigation system was developed in the 1970s, but the Soviet Union was still facing disintegration in the economic downturn, and Russia started to take over later, so the GLONASS system was relatively backward.

Galileo system in Europe was jointly built by many developed countries in Europe, but this navigation system is full of loopholes, which frequently breaks down in the initial stage of operation, many satellites lose contact, and Galileo system can not be reused.

American GPS occupies a very important position in the world. After more than 20 years of research and experiments, it cost 30 billion dollars to build. 1994, the global coverage of GPS has reached 98%, but GPS has only 24 satellite constellations.

China's Beidou has 55 satellites, and its positioning accuracy is more accurate. It can provide high-precision and high-reliability positioning, navigation and timing services for all kinds of users around the world, and has the ability of short message communication. It has initially possessed the ability of regional navigation, positioning and timing, and the positioning accuracy is decimeter and centimeter. The positioning accuracy in the Asia-Pacific region will be better than 5 meters, while the GPS in the United States only achieves a single-machine navigation accuracy of about 65,438+.

The positive significance brought by China Beidou is very significant. According to the standards of the International Maritime Organization and the International Search and Rescue Satellite System, it serves the global users. In addition, China's Beidou has been applied in military and civilian fields, which has a certain impact on GPS.

According to the long-term development plan of the national satellite navigation industry, the output value of China's satellite navigation system will exceed 400 billion yuan by 2020, and China will completely change the dominance of GPS. In the future, Beidou system will continuously improve its service performance, expand its service functions and enhance its continuous and stable operation capability. I believe that with the continuous development of China, China will become more and more prosperous. So what else do you want to say about this?
