XICHANG, Nov. 19 (Xinhua) -- China sent two new satellites of the BeiDou Navigation Satellite System (BDS) into space on a Long March-3B carrier rocket from the Xichang Satellite Launch Center in Sichuan Province at 2:07 a.m. Monday.

The satellites entered a medium earth orbit more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42nd and 43rd satellites of the BDS satellite family.

With the successful launch, the basic BDS constellation deployment is complete. China plans to provide navigation services with the BDS-3 to the Belt and Road partner countries by the end of this year, marking a key step toward a global navigation service.
