I have version V5.3, the newer the better.
Run the app in an open place such as the roof, select the location, and you can see the satellite list and star map.
First, determine the number of systems: see if there is gps glonass Beidou Galileo qzss.
Then observe the satellite list and pay attention to the following points.
A. If you agree that a satellite has two data, the elevation and azimuth satellite numbers are the same, but the carrier-to-noise ratio is different: your mobile phone supports the dual-frequency signal of the system.
B. If there is a gps star larger than 32: Your mobile phone supports sbas, the satellite-based enhancement system mentioned above.
C. If there are only 1 to 16 Beidou satellites, there are no twenty or thirty Beidou satellites: your mobile phone only supports the Beidou regional system "Beidou II" and does not support the recently overheated Beidou III.
D if it is more than 16 and less than 37 Beidou satellites: you are a user of Beidou-3.
E. If one or more stars are located at the top of the map, the elevation and azimuth are both 0: there is something wrong with this satellite, maybe there is a bug in the receiver, or maybe there is something wrong with the satellite message, so it doesn't count.
Third: GPS test plus must be 1.58 or above. The old version of the system is not supported enough.
The sky was full of stars, and 54 signals were received, 48 of which participated in positioning. Then click on the three points in the upper right corner and select the satellite filter.
There are legends here, and different shapes represent different systems. You can choose to look at only one or several of these systems, so that you can know which systems your mobile phone supports.
Similarly, if the Beidou satellite number is limited to 16, it means that your equipment only supports Beidou-2, and only when you receive multiple Beidou satellites from 16 to 37 can your equipment support Beidou-3.
What is turned off/on here is whether the system is displayed on the software interface, and it does not affect which systems are used by the mobile phone receiver for positioning calculation.
In other words, even if only Beidou is turned on here, all satellites are used for positioning in the mobile phone.
To check whether the smart phone supports Beidou system, we must first look at whether the hardware supports it. As ordinary users, we can't take apart the mobile phone to study the parts. We just need to go to official website to check the introduction page of vehicle performance and search for the keyword "positioning". For example, Huawei mate30pro mobile phone, a common domestic mobile phone, can clearly see its supporting positioning systems in its positioning details, namely GPS in the United States, GLONASS in Russia and Galileo in Europe.
It is worth noting that all Apple phones do not support Beidou system. As mentioned earlier, whether to support Beidou is determined by hardware. If you query your own model to support Beidou, does the mobile phone use Beidou signal? This is the smart switch of mobile phone. If you really want to see which system the positioning signal in the mobile phone belongs to, you need to download a special tool software to see the signal strength of the connected satellites, the number of satellites and the system you belong to in real time.
Beidou's successful global networking is of great significance to China, which means that we are truly autonomous and controllable in the positioning system and pay tribute to countless scientists and engineers again. Finally, please take out your mobile phone and see if your mobile phone is connected to the positioning signal of Beidou.
