最新北斗导航卫星成功发射。

四川西昌卫星发射中心周二凌晨1时43分,以长征三号乙运载火箭成功发射中国第49颗北斗导航卫星,随着该卫星发射成功,北斗三号系统3颗倾斜地球同步轨道卫星已悉数发射完毕,为明年完成北斗三号全球组网打下坚实基础。

今次发射的北斗导航卫星和配套运载火箭,分别由中国航天科技集团有限公司所属的中国空间技术研究院,以及中国运载火箭技术研究院研制,属长征系列运载火箭第317次飞行。

北斗三号首发卫星于2017年11月顺利升空、成功入轨,随后2年当局还完成16次卫星发射任务,成功将24颗北斗三号组网卫星及2颗北斗二号备份卫星送入预定轨道。目前,北斗三号系统建设进入关键阶段,后续还将发射6颗北斗三号组网卫星,全面建成北斗全球系统。
