China successfully sent twin satellites into space on a single carrier rocket on Monday, marking the third launch of the self-developed BeiDou-3 Navigation Satellite System.
 
本周一,中国用一颗运载火箭成功将两颗北斗卫星送入太空,这是我国自主研发的北斗三号导航卫星系统第三次发射。
 
 
The pair blasted off on a Long March-3B carrier rocket at 1:03 p.m. BJT from the Xichang Satellite Launch Center in southwest China's Sichuan Province, and entered the preset orbit about three hours later. 
 
Named after the seven bright guiding stars, the BeiDou navigation system has been providing navigation services in the Asia-Pacific region since 2012. It is scheduled to cover countries and regions along the Belt and Road by 2018. A  complete 35-satellite network allowing global coverage1 will also be in place by 2020.
