薪火传承 人类命运共同体的中国担当——专家详解风云二号H星

2018-06-06 10:51:03    新华网

风云二号系列卫星共有三个批次。H星属于第三批最后一颗星,其主要功能与第三批的前两颗星F星和G星一致,但技术人员研制每一颗新的风云二号气象卫星时,都会充分总结前一颗卫星的经验,用以指导新卫星的研制,所以H星是风云二号所有卫星中可靠性最高、性能最稳定的卫星。本次H星相对G星,共有15项技术得到改进和提升。H星投入业务运行后,将在台风、暴雨等灾害性天气及沙尘暴、森林草原火灾的监测中发挥着重要作用,为防灾减灾提供更加准确的决策信息。

记者:据了解,风云二号H星的定点位置由原定的东经86.5度更改为东经79度,这是为何?

  赵坚:这次风云二号H星的定点位置由原定的东经86.5度更改为东经79度,是应世界气象组织和亚太空间合作组织要求而做的变动。偏移后我国风云系列静止轨道气象卫星可有效覆盖我国全境、“一带一路”沿线国家和地区、印度洋和大多数非洲国家。

 

  风云二号H星的定点位置由原定的东经86.5度更改为东经79度后的覆盖范围。

众所周知,静止轨道气象卫星定位于赤道上空,距离地球36000公里,位置相对固定。卫星定点经度的改变对卫星姿态控制、数据传输等技术方面提出的新要求,目前的技术力量可以完全满足。

根据国际灾害数据库的统计,“一带一路”沿线地区高山、沙漠、海洋等无人区较多,气象资料缺乏,自然灾害严重,相对灾害损失是全球平均值的两倍以上,且以气象灾害居多。风云二号H星定点位置向西部布局,对该地区应对自然灾害、落实该地区对静止轨道气象卫星数据获取及应用的需求有着重要意义。
