Unlike Huawei's 5G, which has been suppressed in many foreign countries, even the United States, which has repeatedly attacked us in the field of science and technology, has nothing to do with our Beidou. So far, there are four suppliers recognized by the United Nations Satellite Navigation Committee in the world. In addition to China's Beidou system, the other two are well-known GPS in the United States, Galileo in the European Union and GLONASS in Russia, which may be rarely noticed.
How powerful is Beidou satellite navigation system? Do I need to pay? First of all, Huawei's 5G technology is really powerful, but it is still not as good as Beidou satellite navigation system. Beidou system not only involves many social service fields, but also concerns national security. Secondly, many people are puzzled why downloading many apps with the name of Beidou system prompts them to pay. Although the money is not much, it has caused controversy.
In fact, Beidou satellite navigation system is not an APP. Whether the Beidou system can serve you depends on whether your mobile phone chip is compatible with this navigation function. More than half of the smartphones currently on sale in China are compatible with Beidou navigation, but all chips of Apple phones are not compatible with Beidou.
Simply put, as long as your mobile phone is not compatible with Beidou, even if you pay to download an APP, you are not actually using Beidou navigation. In fact, before the successful launch of the last satellite of Beidou-3, not many people paid attention to Beidou navigation, but at first it was mainly used for military purposes like other navigation systems, which is probably why many people were fooled by the APP of the same name. "Dongfeng Express" can reach every destination accurately before public use.
Of course, the Beidou system, which we have spent 20 years building, can not only help national security and economic development, but also provide services to people all over the world, which is exactly the phrase "China's Beidou, the world's Beidou". As long as people live on the earth, no matter where you live, our Beidou satellite system can provide them with positioning and navigation services, and it will also be used in other fields closely related to everyone's life, such as disaster relief, hydrological monitoring, emergency search and rescue and weather forecast.
Why, unlike 5G technology, the powerful United States has nothing to do with Beidou system? Up to now, more than 100 countries in the world have signed cooperation agreements with China Beidou system. The success of global networking will greatly expand the future international application space of Beidou system. Why didn't the United States hinder the overall deployment of Beidou system in China this time? For those countries that can't independently develop navigation systems, one more navigation system is equivalent to one more choice, without relying entirely on anyone. Why don't they leave themselves a way out?
So many countries are willing to accept the Beidou system, and whether the United States likes it or not, it is difficult to influence others' choices. China Beidou satellite system is an independent satellite navigation system. We don't rely on American technology. Because they didn't help, Beidou was successfully built, which means that we not only no longer rely on GPS, but also further consolidate the national security construction.
Moreover, our Beidou system is based on the principle of openness and compatibility, and other satellite navigation systems can also be compatible with us in order to better provide quality services for the majority of users. In fact, our Beidou system has more high-orbit satellites and stronger anti-occlusion ability, which will be more prominent in those low latitudes. This is not only to meet our own socio-economic and national security development, but also to provide more reliable satellites for people in other countries. The deeper the international cooperation, the more intelligent the application benefit of satellite navigation system.
The construction of Beidou system is very difficult, just as its function is very powerful today! Although the Beidou system mainly consists of three parts, namely, the user part, the ground part and the space part. However, only the space segment involves three types of satellites: medium-earth orbit satellites, geostationary orbit satellites and tilted geosynchronous orbit satellites. The ground segment covers not only the inter-satellite link operation and management facilities, but also monitoring stations, main control stations, injection stations (time synchronization) and other ground stations, while the user segment covers many basic products, such as whether the chip mentioned at the beginning is compatible with Beidou system.
The construction of Beidou took decades. In fact, the "three-step" development strategy of Beidou system was planned as early as 1980s, namely, Beidou-1 system (launched in 1994, and five geostationary orbit satellites were launched in 2000 and 2003) and Beidou-2 system (launched in 2004, deployed in 20 12 years1.
