This National Day, car owners who are preparing to drive for self-driving will be surprised to find a line of words when opening the commonly used Baidu Map navigation APP.
According to Global Times on October 5, Baidu Map has announced that it will give priority to the use of China's Beidou satellite navigation system positioning instead of the United States GPS. The relevant service name has also been changed to Baidu Map's Beidou positioning open platform, and the daily positioning volume of Beidou satellite has exceeded 100 billion times. Since the Beidou satellite navigation system was launched, Baidu Maps has launched map navigation and positioning services based on Beidou system , and its application level has continued to deepen in recent years. With the support of Beidou , the data security and reliability of Chinese navigation travel have been further improved.
According to Baidu official introduction, Baidu maps, which are positioned with Beidou satellite navigation system, have priority, and their functions have become more powerful than before. Through the Beidou system, Baidu Map has realized lane-level navigation and parking space-level navigation and other functions. The so-called lane-level navigation can help users obtain information on accident lanes ahead in real time in high and expressway driving scenarios, guiding users to avoid dangerous lanes in advance; parking space-level navigation is aimed at parking scenarios, helping car owners find free parking spaces faster. Obviously, Baidu Maps can achieve these two functions inseparable from the high-precision positioning of Beidou Navigation , and its positioning accuracy has been improved from 5-10 meters to less than 1 meter.
Beidou navigation can achieve accuracy less than 1 meter in the civilian field. It can be imagined how powerful the functions of Beidou navigation are in the military field and how accurate the positioning is! It can be said that with the "blessing" of Beidou navigation, it has reached the level of hitting wherever it is pointed.
Once upon a time, because China did not have its own satellite navigation system , it not only depends on the United States' expression in the civilian field, but also was controlled by others in the military field and was completely "bottled" by the United States. In 2003, China invested US$259 million to cooperate with EU to develop the Galileo navigation system, but because the United States interfered, the EU kicked China out of the game. This series of events shows that if key technologies are not in their own hands, they will always become the "weakness" of national security. Therefore, the country devoted itself to the research and development of its Beidou navigation system, and was the first to put it into use than "Galileo".
Beidou satellite navigation system has successfully integrated the network, which has completely broken the monopoly position of the satellite navigation system of the United States and European countries, and has higher autonomy and security in the military and civilian fields. There is no longer any need to worry about being cut off by the United States and European countries during wartime, making the People's Liberation Army "blind". On the contrary, the latecomer advantage of Beidou navigation is more obvious than that of the US GPS. Its functions are far beyond GPS, and its positioning accuracy is even greater than that of GPS.
Over the years, the People's Liberation Army has equipped with various weapons and equipment for Beidou navigation to shine in practical applications. Take the "table-lock-type" military exercise held by the People's Liberation Army on August 4 for example. It is not that the United States has not mastered the PLA's movements and interfered with the PLA's live-fire shooting through GPS, but all the PLA's weapons and equipment are loaded with Beidou navigation, so the United States can only stare at this. During the exercise, the People's Liberation Army set the shooting range on the east side of Taiwan Island for the first time. The Army's new long-range box rocket launcher carried out long-range live-fire shooting in Taiwan Strait , and carried out precise strikes on specific areas in the eastern Taiwan Strait; the Rocket Force carried out multi-regional and multi-type regular fire assaults on the designated sea areas outside the eastern coast of Taiwan Island, and all missiles hit the target accurately. At this time, the ship of the US Navy did not care about its face and retreated far beyond the PLA's attack range.
Beidou navigation continues to advance in the civilian field, and will also promote the development of the military field. The development of military technology requires money to be piled up. The greater the support for the civilian field, the more beneficial it is to the development of the national economy, the more money the country will have to promote Beidou Navigation to launch more satellites and study more advanced technologies.
