The situation of the world satellite positioning system
The civil positioning accuracy of Beidou satellite is 10 meters, the velocity measurement accuracy is 0.2 meters/second, and the timing accuracy is 10 nanoseconds. This is the positioning data that can be made by the mainland's Beidou satellite positioning system after the launch of the mainland's last positioning satellite.
In the face of such astonishing data, the United States was the first to sit still, and even openly intimidated the mainland, and then launched it to knock it down!
So what is it that can make the United States, which has the world's most accurate GPS positioning system, make such a huge response? We must first start with the situation of the world's satellite positioning system.
As we all know, GPS is currently the world's largest number of users, involving the widest range of satellite positioning system, up to seventy or eighty years old old to six or seven years old children, all have a more or less understanding of GPS, deeply loved by people all over the world.
Since it was opened to the outside world in 1995, every household can now enjoy its convenience, and the United States has spent more than 20 years on this road.
The 28 synchronous satellites launched by the United States provide two positioning signals for the GPS positioning system. Exclusive civilian C/A code, can maintain the accuracy of positioning at about 100 meters, upgraded P code, its accuracy can reach within 3 meters, although the United States said that this technical knowledge for the upgrading of ordinary civilian technology, but the fact is that it is a special technology for the United States to do military strikes.
The excellence of the GPS system has greatly affected the position of the United States in the military, economy, science and technology, etc., and it can be said that the United States has been able to occupy the first place in the world's development for a long time, and GPS is indispensable.
After talking about GPS, you may think, is there no other positioning system that can compete with it? As everyone guesses, we will introduce the world's second most accurate satellite positioning system - Russia's GLONASS satellite positioning system.
In fact, the GLONASS system was formed earlier than GPS, and in the early days of its establishment, the GLONASS system was mainly to meet the militarization of the Soviet Union and resolve the military crisis faced by the Soviet Union.
Later, in order to meet the needs of the Russian people, the GLONASS system gradually began to move towards civilian use, and with the upgrading of products, its accuracy has been continuously improved, and it has been almost at the same level as GPS.
It is said that at high latitudes in the Northern Hemisphere, the accuracy of the GLONASS system is even much higher than that of GPS.
Back to the point, according to the New York Times, China's Beidou satellite positioning system was officially integrated into the global radio navigation system by the United Nations Maritime Safety Commission.
Once this information is issued, it marks that the mainland's Beidou satellite positioning system has successfully entered the global satellite positioning system situation monopolized by GPS and GLONASS for a long time, and the tripartite situation has been formed.
So, what did the Beidou satellite rely on to break the long-standing predicament?
The competitive advantage of Beidou satellites
At present, the Beidou Satellite Positioning System is composed of nearly 30 near-Earth satellites, which not only provides accurate and reliable positioning services for users in China, but also provides a large number of accurate services on a global scale.
Moreover, the reason why the Beidou satellite positioning system can break the monopoly of other major countries is that its own accuracy is indispensable.
The positioning accuracy of the Beidou satellite positioning system can reach 10 meters worldwide, the speed measurement accuracy is 0.2 m/s, and the timing accuracy is 20 nanoseconds. Even, in the Asia-Pacific region, the timing accuracy of Beidou can reach 10 nanometers, and in some regional scenarios, the Beidou satellite positioning system can reach the terrifying centimeter level.
The short message communication function of the Beidou satellite positioning system is even more indispensable. The short message function is a unique function of the Beidou satellite positioning system compared with other satellite positioning systems, which can enable the Beidou satellite and the ground service base station to transmit information directly through the satellite, which greatly improves the efficiency and accuracy of positioning.
It can be said that in areas where there is no signal, such as deserts and seas, the short message function can use its own technical characteristics to implement information feedback and transmission, and provide users with the services they need in the first time.
Secondly, ground infrastructure is also a strong support behind the relatively rich services of the Beidou satellite positioning system.
In order to ensure the accuracy and timeliness of the normal use of Beidou, the mainland has established a full range of ground signal enhancement stations on land, sea and sky, and has established more than 2,500 ground information enhancement stations so far.
At 23:33 in 2016, the mainland's 16th Beidou satellite was successfully launched, according to Zhao Xiaojin of China Aerospace Science and Technology Corporation, this launch is an important step for the mainland to achieve a huge impact in the field of satellite navigation in the world and compete for a strong voice in the field of satellite navigation.
So, what is the significant impact of the success of the Beidou satellite?
The impact of the basic formation of Beidou
In the past, the mainland's satellite positioning was still in the realm of poverty and whiteness, and there were not many technologies and facilities at all. After a long period of hard work, the mainland has finally developed an exclusive satellite positioning system and achieved a great turnaround in the field of satellite navigation.
In addition, in the face of the rapid development of the mainland's satellite field, the United States has also carried out some special "care" behaviors, and in order to target the mainland's satellites, the United States has developed a small monitoring satellite and launched it into space.
Such shameless measures have not only greatly affected the normal operation of the mainland's satellites, but also caused the normal life of the people on the mainland to be subjected to a situation of semi-surveillance.
In the past, the United States regarded Asia as its own garden, and when the mainland's scientific and technological strength was not yet developed, news of US warships sailing into the South China Sea often appeared, and the mainland was very angry at this behavior, but due to the oppression of strength, the mainland could only make a verbal drive away and a "counterattack" of duty.
It is said that after the appearance of the Beidou system, the United States still tried to infringe on the mainland's territorial waters, but to the surprise of the Americans, the GPS system, which had once made the United States proud, directly lost its effect after entering the South China Sea area, and the US warship was like a blind cat, with no direction in the end, and finally had to flee in the desert.
In recent years, with the advancement of national intelligence, the implementation of the Internet industry has advanced by leaps and bounds, and the rapid development of Beidou, the automotive field is the first to bear the brunt.
If the driver is the brain of the car, then navigation is the eyes of the car.
According to incomplete statistics, in 2022 alone, the number of operating vehicles installed with Beidou navigation terminal products in mainland China has reached 7.9 million, and in 2025, the basic map standard system for smart cars will be basically successfully built.
At that time, Beidou navigation will become an indispensable tool for tens of millions of vehicles, lighting a safe and reliable guiding light for thousands of families in China.
Smart city is the hottest topic in mainland China in recent years, the state and the government are actively promoting the formation and improvement of smart cities, and the Beidou positioning system is also regarded as one of the most important elements of building smart cities.
The Beidou positioning system is used in various aspects of urban emergency rescue, food safety transportation, environmental governance and supervision.
Take the sharing economy that is currently rising, the sharing economy attaches the most importance to the regional management and ownership of products, and the emergence of the Beidou positioning system provides the most needed security positioning for the sharing economy, so as to vigorously promote the investment enthusiasm of businesses and the peace of mind of consumers.
The emergence of the Beidou positioning system not only makes the domestic society greatly convenient, but also the most obvious business card of the mainland's continuous rise and strength.
As everyone knows, the mainland is not a country that is willing to be attacked by other countries, and in the face of any unreasonable provocation, the mainland will eventually come up with a strong counterattack, so what kind of counterattack will the mainland come up with in the face of the above-mentioned threats made by the United States to prevent the development of the mainland's satellite field?
The best counterattack
At present, the Beidou positioning system was originally customized for military operations like the Russian GLONASS, and after a long period of evolution, it has become the popular Beidou positioning and navigation system.
And with the development of the times and the needs of modern warfare, the Beidou positioning system has made new changes for modern warfare.
In terms of missile launches, the centimeter-level precise positioning of the Beidou system can be used for mobile ballistic missiles, long-range cruise missiles, aircraft carrier formations, etc., to provide extremely accurate position correction and locking services.
At the same time, aerial bombs using Beidou navigation and guidance can basically be operated intelligently, achieving a high hit rate and high efficiency in combat where they are directed, thus satisfying the needs of modern warfare for concise and clear one-time strikes.
In addition, the emergence of the Beidou positioning system can make joint operations of the sea, land and air forces possible, and all the information of the land, sea and air forces can be quickly and effectively communicated through the short message function of the Beidou positioning system, which has greatly improved the combat effectiveness and execution capability of the mainland army.
Military strength is not only an important step in enhancing the mainland's national strength, but also a powerful counterattack by countries in the international community that are eyeing the mainland's development, and completely dispelling their delusions about the mainland.
As Chinese nationals, we must first maintain a high degree of technological self-confidence, and maintain a high degree of external awareness, and in the face of the threats and oppression of other countries, we must strengthen our own will and conviction without urgency and resistance, and use technical means to let other countries' arrogance reap the consequences.
