China’s Beidou Satellite Navigation System began construction in 1994 and was officially fully commissioned as the third generation on July 31, 2020. It currently has 58 satellites and was officially certified by ICAO as one of the global civil aviation navigation system standards in November 2023. . Chinese media recently reported on the accuracy data of Beidou satellites, stating that its accuracy is superior to that of GPS.
According to “Quick Technology”, global monitoring results in February 2022 showed that the B1C frequency point positioning accuracy of the Beidou system reached a horizontal accuracy of 1.76 meters, an altitude accuracy of 3.14 meters, and a space signal accuracy of 0.49 meters, while the horizontal accuracy of GPS was 2.23 meters. , the elevation accuracy is 4.28 meters, and the spatial signal accuracy is 0.85 meters. According to Kuai Technology reports, this shows that the positioning accuracy of the Beidou system far exceeds that of GPS, and various indicators are also significantly ahead.
In addition, according to data quoted by “Quick Technology”, the horizontal positioning accuracy that the Beidou system can achieve in the Asia-Pacific region is 1.32 meters and the vertical accuracy is 2.14 meters, while globally, the horizontal positioning accuracy that can be achieved is 1.53 meters and the vertical accuracy is 2.59 rice.
The Global Positioning System (GPS), also known as the Global Satellite Positioning System, is a positioning system that the United States began to develop in the 1970s, was first launched in February 1978, and was fully completed in 1994. The Beidou system currently used in China is the third-generation Beidou system and was officially put into full use on July 31, 2020.
