How about the Beidou positioning system developed by my country? 5

The Beidou Navigation Satellite System has become ubiquitous, from map navigation to takeout to garage parking. More than 100 million mobile phones around the world use the Beidou navigation system. The development of the Beidou system is a process of continuous innovation and pioneering spirit.

The main achievement of BDS-1 is that the two satellites have achieved a wide range of high-precision positioning and timing services, covering China and surrounding areas. According to the GPS positioning principle, 12 satellites are required, and the two-way timing accuracy is 10ns, which is the world's leading. Targeting and reporting can be done at the same time on the same channel.

Beidou is the world's first navigation system with complete three-frequency service capabilities. Beidou is the world's first dual-mode integrated system for continuous navigation and positioning reporting. Dual-mode user computers bring great social and economic benefits.

The main achievement was the independent establishment of global benchmarks in time and space, since only the global system is a representative of the global system, and those regional systems do not have the capacity to establish a temporal baseline, so the Beidou system does not. The Big Dipper is actually a voyage from the first stage to the fourth stage, so the achievements of the Big Dipper are intergenerational.

After the completion of China's Beidou, it has basically reached the L-frequency meter level of navigation accuracy. In 2030 or 2035, a space system with deep navigation, communication, and remote sensing fusion will come from China, China's high-speed network uses 5G terrestrial network to achieve global sky object and content connectivity, the sixth generation of mobile communications, China's 6G road is different from that of Western countries, China is to build a ground system first, and then build a space system, China's space system is based on the Beidou space-time benchmark, so China's 5G will be successful, and China's 6G will also be successful.

In the future, there will be a Beidou global Internet of Things. The internet is a connection between people, and people are very accommodating. In order to connect the world's dynamic things, the global Internet of Things must be maintained within a spatiotemporal datum.

The world-class dynamic decimeter-level Beidou satellite navigation system has been realized, providing a space-based Internet of Things with a unified space-time datum, and obtaining the cognition of the earth by the space-based radio global system. Its significance is to give full play to the basic value of the Beidou space-time benchmark, break the solidified state of navigation, communication and remote sensing in the world's independent construction industry, and provide public data links for most industries, including remote sensing. The Beidou multi-service satellite radio system is an important space information infrastructure in China.

BDS-3's comprehensive innovation in the fields of basic navigation, satellite-based augmentation, precise single-point positioning, information and communication, and international search and rescue is a good start for future development.

There are a lot of unique features that can be used for positioning, and then can also be used for satellite communication, to better understand the weather conditions, to conduct international search and rescue, and to deal with cases.

You can get in touch with others, you can navigate, you can also carry out research and development in this area, you can conduct all-round searches, you can also spread relevant signals, and you can also keep abreast of other people's distress signals.

Beidou applications have five major advantages:

1. It has both positioning and communication functions, and does not need the support of other communication systems, while GPS can only be positioned.

2. With large coverage and no communication blind spots, the Beidou system covers China and neighboring countries and regions, and can serve not only China but also neighboring countries.

3. It is especially suitable for large-scale monitoring management and data collection user data transmission applications of group users.

4. Integrate the two major resources of Beidou navigation and positioning system and satellite augmentation system, so GPS can also be used to make its application more abundant.

5. Autonomous system, safe, reliable, stable, strong confidentiality, suitable for key department applications.

We Chinese still need time to accept the Beidou satellite navigation system. However, we believe that China's Beidou navigation system will gradually replace the US GPS. At that time, the Beidou navigation system will be used nationwide, instead of using the global positioning system of the United States.

The U.S. Global Positioning System (GPS) is the world's oldest satellite positioning and navigation system, and it is currently the satellite navigation system with the largest number of users in the world, even in China. Many users have long been accustomed to using the global positioning system satellite positioning and navigation system of the United States, especially the dual-band global positioning system launched by Xiaomi mobile phones, which has been well received by most users. As for the Beidou satellite positioning and navigation system, I believe that there are still many people who do not understand, and naturally few people will use it, especially the current domestic map navigation software, which still uses the global positioning system navigation system.

Of course, at present, China's Beidou navigation system is the most widely used in the military field, followed by cargo ships and shipping. It is also widely used. I'm sure many people remember that when China had not yet developed the Beidou navigation system, the United States directly shut down the global positioning system on Chinese cargo ships, resulting in many Chinese cargo ships being stranded at sea for more than 20 days.

Although GPS satellite positioning systems are free, they are still "controlled by others". As a result, China opened an era of research and development of China's navigation system.

Looking at the world, there are currently four major satellite navigation systems. They are China's Beidou Satellite Navigation System, the United States' Global Positioning System, Russia's Global Navigation Satellite System, and the Galileo Satellite Navigation System (GSNS) developed by the European Union. At present, the most commonly used smartphone is the global positioning system (GPS positioning system) in the United States, but in fact, almost all domestic smartphones currently support the global positioning system and the Beidou navigation system, which means that even if your mobile phone is currently using Beidou navigation, you may not know it.

The era of Beidou's global positioning has officially begun, which also means that we Chinese can finally use our own satellite positioning and navigation system.

China has completed the Beidou global positioning system, but why are domestic mobile phones still using GPS?

It may be because this batch of domestic mobile phones has not had time to update the system.

I think it's probably because mobile phones don't support food satellite systems.

This is because there are many mobile phones that cannot apply the Beidou navigation system to mobile phones.

Chinese GPS is the United States.

China's satellite navigation system currently in the development and trial stage is the "Beidou" system, the accuracy of Beidou is not high at present, and it cannot be fully used for practical use, and GPS is a passive navigation system, Beidou is an active navigation system.
