Most people have map apps on their phones that can show their locations and guide them to where they want to go. But how do these app systems know your location at any time or place? They find you by using satellite navigation system(卫星导航系统).

A navigation system uses groups of satellites to find the user’s locations. This location information is then sent to a receiver.

The first navigation system is the Global Position System(GPS)(全球定位系统), which belongs to the United States. The system is the world’s famous navigation system. But China’s satellites are important for improving the navigation system. Beidou, has overtaken(超过) GPS in size, Japan’s Nikkei Asian Review reported.

China sent Beidou’s first navigation satellite into space in 2000. China also became the third country to build a navigation system after the United States and Russia, People’s Daily reported. As of right now, over 30 countries in Africa and the Middle East are using the Beidou system.

With its world-leading technology, Beidou is leading Chinese people to a better life by playing important roles in different areas, according to Xinhua News.

For example, over 6.2 million vehicles in China are using Beidou for navigation, according to a report on the Beidou system’s construction and development.

At the newly built Beijing Daxing International Airport, Beidou has been used to keep track of(追踪) loading and unloading vehicles indoors and outdoors. When the airport opens, each baggage cart has Beidou navigation equipment to help passengers get their luggage faster.

For a navigation system, the number of satellites is important for improving the system’s positioning accuracy(定位精度). The more satellites, the more accurate the positioning is. The satellite navigation system is useful in many ways.
