Is the navigation system on our mobile phone Beidou or GPS?

Whether the mobile phone uses Beidou or GPS navigation can be said to be in use, but the user does not know which navigation system is currently used. No matter which navigation system is used, there is no obvious difference perception for users. After all, this is the process of determining and selecting the SoC chip of mobile phone. Beidou or GPS navigation is a dynamic switching process, and the mobile phone will choose the navigation access with the best current signal.

GPS navigation system is the earliest satellite navigation system developed in America. In order to avoid the restriction of satellite navigation by the United States, China started the research and development of Beidou satellite navigation system in the 1980s, which was completely independently developed by China. Now there are four navigation systems in the world: Beidou satellite navigation system, American GPS, Russian GLONASS and European Union Galileo.

At present, there is a certain gap between Beidou satellite navigation system and American GPS navigation accuracy. The GPS navigation system in the United States is divided into two parts. The military accuracy can be 0.2 to 0.4 meters, and the civilian accuracy is about 10 meters (the United States will not open higher-precision navigation). The military accuracy of Beidou satellite navigation can not reach the same level of GPS for the time being. The civil precision in the Asia-Pacific region is 5m, and the global precision is10m.

Because GPS navigation was introduced earlier, the navigation names of many smart phones directly adopted GPS. In fact, the navigation system supported in mobile phones is not only GPS, but also many other navigation systems. So, how should I check whether my mobile phone supports Beidou satellite navigation system? In fact, except for Apple mobile phones, most domestic smart phones support Beidou satellite navigation system, which has become the standard of domestic smart phones.

One is that you can inquire through the introduction of mobile phone parameters. If you can find the word Beidou in the column of mobile phone data connection and GPS navigation, it means that this mobile phone supports Beidou satellite navigation; One is that you can query by installing AndroiTS GPS test software. As long as you can find a flag icon similar to the one below, it means that the mobile phone supports it.

Civil products cannot specify the current navigation system. In most cases, you have used the Beidou satellite navigation system, but you don't know the truth.
