According to the official news of my country's Beidou satellite navigation system , Beidou has become the largest navigation system in my country, and the usage of Beidou navigation is 30% more than the second place GPS. In addition, according to the data provided by Gaode Map , the number of Beidou positioning used by Gaode map is as high as 210 billion times in a single day. In addition, more than 130 countries around the world are currently connected to the Beidou system , and Beidou has also jumped to second among the four major positioning systems in the world.

positioning system is extremely important for both individuals and countries. In ancient my country, compass was invented, which could point out the direction for people on the journey, but with the development of science and technology, ancient developments were obviously no longer satisfied with the use of modern military industry and commerce. my country once cut off GPS by the United States because it did not have its own navigation system, causing a sensational "Galaxy" incident. At that time, my country's "Galaxy" merchant ship carried stationery, hardware and other goods from Tianjin New Port . When sailing to Indian Ocean , it was blocked by the US military. Later, the GPS positioning service was cut off and there was no navigation and there was no need to stop. The US military's excuse is that the Galaxy is loaded with dangerous chemicals, and then illegally detained the Galaxy in the deep sea for 33 days, which not only caused huge economic losses, but also the Galaxy crew members were injured to varying degrees due to long-term mooring. Therefore, having an independent navigation system is of great significance to Ocean Trade.

Beidou is the latest generation of global navigation and positioning system in my country after more than 30 years of research and development, and is also the most advanced navigation system in the world. The Beidou system has four major functions, namely short-pass text communication, precise timing, high positioning accuracy and maximum number of users to accept. Short message communication is not very useful in civil use in real-time, and is crucial for ocean-going navigation. Beidou can perform time calibration and synchronization of users with 20NS-100NS accuracy, which is also a leading position among the four major positioning systems. Beidou's global positioning accuracy can reach within 10m, the speed measurement accuracy can reach 0.2m/s, and the positioning accuracy of in the Asia-Pacific region of can reach within 5m. Beidou can also accommodate up to 540,000 users per hour, and is also an industry benchmark in positioning and navigation.

Beidou system currently has a total of 54 satellites in orbit, including stationary orbit satellite and non-stationary orbital orbit satellites. The lifespan of the Beidou system is generally between 8 and 12 years. If maintenance and replacement are required in the later stage, the satellites launched may have a longer life and smaller size. Although everyone calls it Beidou navigation system, it is only its main business. Beidou can also perform tasks such as meteorological detection and prediction, road traffic management, railway intelligent traffic management and emergency rescue. Beidou navigation system is also recognized by the United Nations as the third global positioning navigation system. Currently, the positioning and navigation systems recognized and put into use by the United Nations include GPS from the United States, Gronas from Russia, Beidou from China and Galileo from the European Union .

Of course, Beidou has brought great convenience to the people in civil use, and it also plays an important role in military affairs. Take this Russian-Ukrainian conflict as an example. Gronas can make an indelible contribution to the Russian military's ability to accurately attack Ukraine's hydropower facilities and military targets. There is also the United States in Gulf War , which can use GPS to accurately blow up the dam of Iraqi . Iraq's proud army has nowhere to hide in the eyes of the US military with GPS. The US military's missiles accurately blow up the pride of the Iraqi army. The iron shells everywhere show the importance of global positioning in modern warfare.

In addition, Beidou can also conduct scientific research that cannot be achieved before. For example, further develop scientific research in meteorology, geography, astronomy, magnetic fields, tides, poles and other scientific fields. In the future, Beidou can truly connect everything and greatly promote information exchange, and its commercial value is unimaginable. In the next few years, Beidou's positioning and navigation equipment will exceed more than 9 billion units, with an annual output value of more than 260 billion US dollars. Just like its name, the Beidou system will illuminate your way forward like Beidou Seven Stars . Wherever it is, you will not get lost.Technology is still developing, China is still rising, and Beidou is still upgrading. The future will surely be the journey of the sea of ​​stars.
