It took 26 years to build the world's third mature satellite positioning and navigation system, which has significant significance at the level of military, diplomacy, technology, and even people's livelihood.Navigation positioning does not ask for people, and it is extremely important for military.Once upon a time, the world's GPS positioning system was relying on the US government's GPS positioning system, and the US military was disguised.With the establishment of the Beidou 3 satellite network, it has covered the world, China will not only drive together with the United States in terms of global positioning technology, but also completely decompose with the US GPS system without going up to people.China strives to become a big science and technology country. The 5G technology and the Beidou system are important.Diplomatic means curb.

No longer subject to American GPS

Military and civilian use is of great significance

The last global networking satellite of the China Beidou 3 system was carried off by the Long March series of rockets yesterday and successfully entered the scheduled track.The Beidou system is a satellite navigation positioning system independently developed by China. In 1994, Beijing proposed to build the Beidou system in three steps, covering China first, then covering Asia Pacific, and eventually expanded to the world.Early half a year.Beidou 3 is the third mature satellite navigation system in the world after the US GPS and the Russian Glonass system; the Galileo satellite positioning system in Europe has not been established as soon as the end of this year.

The satellite positioning applications are everywhere by various missiles, modern agricultural fisheries, transportation, earthquake relief, and even mobile phones used by the people.In the late 1970s, the United States successfully launched the first GPS test satellite to take the first step in order to build a global positioning system for military and civilians.Modern military technology emphasizes precise strike capabilities, and satellite positioning navigation is indispensable.The crisis of the Taiwan Strait in 1996 exposed the huge gap between the Sino -US military forces at that time. After more than 10 years, the PLA retired general told the media that at the time, the PLA had launched 3 missiles to launch 3 missiles to the Klong military base about 20 kilometers.The target location, the other two after the launch, lost the signal and did not know it. The PLA analysts suspected that the U.S. military made the GPS positioning signal.The relevant statement is unable to verify, but on the military technical level, the United States can definitely do this strongly.

In the Gulf War in 1991, for the first time, the U.S. military used satellite -oriented smart bombs to show the huge role of GPS in the military world to the world. However, during the war, the United States closed the GPS signal to users including European allies, and some also made some some of them made some some of them.The state is aware that its own positioning system must be built, which cannot rely on the US GPS.After the Gulf War, Europe and China have successively developed satellite positioning systems to avoid being subject to people in military and communications, and ensure that they will not be cut off by the United States at critical moments.

China strives to become a large space country in 2030, and it is the United States and Russia. The completion of the Beidou 3 system is an important milestone, marking that China can completely decompose with the US GPS system.The Beidou 3 system is composed of 35 satellites, compared to 32 GPS, 26 in Russia's Glonass, and 30 in Europe Galileo.The advantage of the latecomers is that they can use the experience of supervising others.The positioning accuracy of the Beidou 3 system in the Asia -Pacific region can be as small as 10 cm, which is better than the 30 cm of the American GPS. Australian space engineering expert Andrew Dempster pointed out that in addition to the higher accuracy, the maintenance and maintenance are easierEssence

Washington Anti -China Space Silk Road

Beidou Global Civil Challenge Many

China's high -tech development is rapid, and individual fields such as 5G technology are still better than the United States. China's satellite positioning and navigation capabilities catch up with the United States. The Beidou system covers the world. It means that in the future, other countries will be picked in positioning and navigation services.The position of the US leadership is not surprising.After years of development, the Beidou civil positioning service has become quite popular in the mainland. Data show that more than 70 % of China mobile phones last year can use Beidou positioning services. In addition to domestic mobile phones, Samsung and other foreign brands also have machine models compatible with Beidou services.At the same time, Beijing Yirui intends to promote the Beidou -people positioning service in the Belt and Road Initiative.Last year, a research report of the U.S. Congress paid attention to that China promoted to other countries to sell space services such as Beidou and shoot satellites to other countries in the name of space silk roads to gradually eat the influence of the United States.

As early as 2013, Thailand and Pakistan have begun to use Beidou.Mainland authorities said that there are currently more than 120 countries with Beidou systems. In the next 15 years, China will fully promote the global positioning navigation services of Beidou.However, if Beidou wants to challenge the status of the US GPS, it has to face a series of arduous challenges.In terms of technology, Beidou has the ability to compete with GPS, but as some mainland experts say, China lacks experience in promoting such global services.Satellite positioning system, the most important thing is stability. Last year, the European Galileo system had a major failure. It was paralyzed for nearly a week, which caused a lot of complaints and criticism.Although GPS has been killed by the US military, the system has run for dozens of years, and the daily stability is high. In order to keep the GPS leading position, Washington will also heavily put pressure on allies and even other countries to curb the civil service of Beidou civilian services.Development space is just like vigorously suppressing Huawei's 5G development space in recent years.In the future, whether the global satellite positioning service will move towards the barriers. The United States, China and Europe have their own attracting AIA to gather into a pile, which is worth paying close attention. In recent years, the United States has developed the space forces to seize the air control.The pace also needs attention.
