BEIJING — China will finish the construction of the BeiDou-3 Navigation Satellite System (BDS-3), with another two geostationary orbit satellites to be launched before June 2020, said Ran Chengqi, a BDS spokesman, on Dec 27.

Dec 27 marks the one-year anniversary of China's BDS-3 system providing global service.

Ran said at a news conference of the State Council Information Office that with the BDS as the core, a more ubiquitous, integrated and intelligent navigation and timing system with comprehensive national positioning is scheduled to be established by 2035.

China sent 10 BDS satellites into space in 2019. The deployment of the core BDS-3 constellation system has been completed with all of the BDS-3 system's medium earth orbit satellites being networked.

With the system's upgraded intelligent operation and maintenance capabilities, the BDS-3 has provided stable and accurate services, boasting a positioning accuracy of better than five meters.

The BDS system has multiple service capabilities, including satellite-based augmentation, short message communication, ground augmentation as well as international search and rescue. It will provide more diversified services with better performance and higher accuracy in 2020, Ran said.

A series of documents on the BDS system were also released to promote the understanding of the system and facilitate its use.
