  执行本次任务的运载系统,基础级为长征二号丁运载火箭,上面级为远征三号上面级,均由中国航天科技集团八院抓总研制。长征二号丁运载火箭是常温液体二级运载火箭,起飞推力约300吨,对应700公里太阳同步圆轨道能力为1.3吨,具备在酒泉、太原、西昌三大卫星发射中心不同轨道要求的单星、多星发射能力。

  远征三号上面级www.51cgfun是一种新型空间运输工具,被称为“太空巴士”,具备20次以上的自主快速轨道机动部署能力,主要用于多星异轨部署任务,可将多个卫星分别直接送入预定空间位置,另外,它在快速灵活进入空间、空间机动和空间利用等方面均可发挥重要作用。

  此次任务是远征三号上面级首次执行1箭3轨发射任务,是长征系列运载火箭的第551次飞行。(完)
