    1月23日(ri),我国首颗高通量通讯卫星(xing)理(li)论(lun)十三号在(zai)轨托付,正式投(tou)(tou)入(ru)利用。理(li)论(lun)十三号卫星(xing)投(tou)(tou)入(ru)利用后,将被归入(ru)“中星(xing)”系列(lie),定名(ming)为“中星(xing)十六号”卫星(xing)。

    理论十三号卫(wei)(wei)星(xing)(xing)(xing)(xing)于(yu)2017年4月12日(ri)在(zai)西昌卫(wei)(wei)星(xing)(xing)(xing)(xing)发命(ming)中间胜(sheng)利(li)发射(she),是我国(guo)自立研发的(de)新一代高(gao)(gao)轨手艺实验(yan)卫(wei)(wei)星(xing)(xing)(xing)(xing),它(ta)冲破了(le)(le)限制我国(guo)航天(tian)(tian)(tian)手艺逾越成长(zhang)(zhang)的(de)诸多瓶颈手艺,为“航天(tian)(tian)(tian)强国(guo)”“宽带(dai)中国(guo)”扶(fu)植(zhi)供给(ji)了(le)(le)无力撑(cheng)持。理论十三号完(wan)成了(le)(le)Ka频段(duan)宽带(dai)手艺在(zai)我国(guo)通(tong)(tong)讯卫(wei)(wei)星(xing)(xing)(xing)(xing)上(shang)的(de)初(chu)次利(li)用(yong)(yong),通(tong)(tong)讯总(zong)容(rong)量达20Gbps,标记着我国(guo)卫(wei)(wei)星(xing)(xing)(xing)(xing)通(tong)(tong)讯进入(ru)高(gao)(gao)通(tong)(tong)量时期。2017年,该(gai)(gai)卫(wei)(wei)星(xing)(xing)(xing)(xing)胜(sheng)利(li)停(ting)止了(le)(le)国(guo)际初(chu)次高(gao)(gao)轨卫(wei)(wei)星(xing)(xing)(xing)(xing)对地(di)高(gao)(gao)速激光(guang)双向通(tong)(tong)讯实验(yan),标记着我国(guo)在(zai)空(kong)间高(gao)(gao)速信(xin)息传(chuan)输范畴走在(zai)了(le)(le)天(tian)(tian)(tian)下前线(xian),成为国(guo)际上(shang)首(shou)个把(ba)握该(gai)(gai)手艺的(de)国(guo)度。同时,这是我国(guo)初(chu)次在(zai)高(gao)(gao)轨长(zhang)(zhang)命(ming)命(ming)通(tong)(tong)讯卫(wei)(wei)星(xing)(xing)(xing)(xing)上(shang)工程化(hua)(hua)利(li)用(yong)(yong)地(di)球(qiu)敏感器、Ka频段(duan)宽带(dai)领(ling)受机等国(guo)产(chan)化(hua)(hua)产(chan)物(wu),完(wan)成了(le)(le)卫(wei)(wei)星(xing)(xing)(xing)(xing)关头焦点(dian)单机的(de)自立可(ke)控(kong),并使(shi)我国(guo)初(chu)次完(wan)成在(zai)卫(wei)(wei)星(xing)(xing)(xing)(xing)上(shang)设(she)置装备摆(bai)设(she)电(dian)鞭策(ce)分体系(xi)来(lai)完(wan)成全寿(shou)命(ming)期的(de)轨道地(di)位(wei)定点(dian)任务,鞭策(ce)我国(guo)卫(wei)(wei)星(xing)(xing)(xing)(xing)平台手艺周全跨入(ru)电(dian)鞭策(ce)时期。

    理(li)论十(shi)三号卫(wei)星首要为中(zhong)国(guo)地域(yu)等地域(yu)用户(hu)供给(ji)办事,可(ke)完成偏僻地域(yu)的挪动通(tong)(tong)讯(xun)基站接(jie)入及(ji)其余行业利用,普遍利用于(yu)企业专网、长途教导(dao)、医疗、互联网接(jie)入、数字消息收(shou)(shou)罗、机载船(chuan)舶通(tong)(tong)讯(xun)和应急通(tong)(tong)讯(xun)等范畴。该星可(ke)便利用户(hu)疾(ji)速接(jie)入收(shou)(shou)集(ji),能知足航空、航运、铁路互联网用户(hu)接(jie)入须要。比拟(ni)传统(tong)C、Ku频(pin)(pin)段通(tong)(tong)讯(xun)卫(wei)星,理(li)论十(shi)三号卫(wei)星终端装备(bei)更(geng)小(xiao)、易于(yu)利用,以流量计费(fei)的贸易形(xing)式比传统(tong)频(pin)(pin)段卫(wei)星的形(xing)式更(geng)显矫(jiao)捷。另(ling)外,理(li)论十(shi)三号卫(wei)星还具(ju)备(bei)疾(ji)速安(an)排、扶植周期短等上(shang)风。

    据领会(hui),后续我国还(hai)将安(an)排超大容量高通量卫星,估计到(dao)2020年构成可笼盖中国全境和(he)(he)亚太地域、容量靠近200Gbps的通讯才能,无力知足“宽带(dai)中国”和(he)(he)国度“一带(dai)一起”扶植任务(wu)对宽带(dai)通讯的火急须要。
