Since the successful launch of the Beidou 1 test satellite in October 2000, China has sent four Beidou test satellites and 55 Beidou 2-3 networking satellites into space for the past 20 years. Some enthusiastic netizens are about to ask. How to use the navigation system? How can I switch my phone's GPS to Beidou?

According to experts in Beidou Navigation, over 300 of the over 400 smartphones currently on the global market can directly use the Beidou Navigation and Positioning System. Whether a mobile phone can use the Beidou satellite depends on the chip it is equipped with.

On July 31, 2020, China officially announced the opening of the Beidou-3 satellite navigation system and provided services to the world. After years of hard work, China's satellite navigation system has finally been completed; Zhengguo”. Now, in addition to GPS in the United States, there is also a new and powerful satellite positioning and navigation system added globally.

After multiple tests, the signal of China's Beidou-3 satellite positioning and navigation system is already very stable. It should be noted that three to five years ago, when we opened the GPS testing software on our mobile phone, it displayed the largest number of GPS satellites in the United States. The best scenario was to display 13 satellites, but it was not particularly stable, usually displaying around 7 satellites.

The specific type of navigation to use is not a personal decision, which means you have no choice, either alone or by rejecting a certain satellite navigation. For example, the software we often use such as Baidu and Gaode is based on the location information provided by the phone itself, and the positioning of the phone itself depends on the phone chip. The phone will automatically search for the satellite with the best current location signal. At present, most Android phones on the market are compatible with BeiDou, such as Huawei Qilin, Qualcomm Snapdragon, MediaTek, etc. However, Apple phones do not currently support the BeiDou system. If you want to check whether BeiDou is serving your phone, you can download a satellite status testing software. You can see which satellites are navigating and positioning your phone.

The official application of China's Beidou is of cross generational significance. Although the GPS system in the United States is free and open, if you want to use it, you must obtain authorization from the United States. Relying solely on this authorization fee, the United States can earn a large amount of fees every year. According to 2013 data, the United States achieved revenue of $56 billion through GPS authorization. Therefore, the emergence of the Chinese Beidou means that we no longer have to pay high GPS authorization fees to the United States.

Today, the author also conducted a test and the results were quite satisfactory. During the test, it was found that China's Beidou satellite and the United States' GPS satellite are on par in terms of signal stability and the number of satellites receiving signals. After multiple tests, the average number of WeChat satellites in both satellite navigation systems is around 7. So what changes will China's Beidou satellite navigation system bring to our lives?

The official opening of China's Beidou satellite navigation system also enables our aircraft, ships, and missiles
