# Construction of BeiDou Navigation Satellite System fully completed

China's self-constructed and independently operated BeiDou Navigation Satellite System (BDS) was officially put into service worldwide on Jul. 31, 2020, opening a new chapter in China's high-quality global navigation service.

On Jun. 23, China completed construction of the BDS with the launch of the system's final satellite, making the BDS China's largest space system with the broadest coverage, best service performance and closest connection with the lives of the people.

China began building the navigation system in the 1990s and has formulated a three-step development strategy. Construction of BDS-1 was completed in 2000, making China the third country in the world to own an independent global navigation satellite system. The deployment of the BDS-2 was finished in 2012, providing positioning, navigation and timing services to users across the Asia-Pacific region.

The 26-year journey of developing the BDS once again attests to the "Chinese speed and accuracy."
