印度版北斗导航卫星发射失败 航天探索遭重创

2017-09-01 10:45:56   国际在线

【环球网军事报道】据俄罗斯卫星新闻网9月1日报道,印度空间研究组织主席表示,印度区域导航卫星(NAVIC)发射失败。据悉,此次发射采用PSLV-C39运载火箭,于当地时间8月31日19时(北京时间21时30分)左右从印度南部安得拉邦的斯里赫里戈达岛的萨迪什·达万航天中心发射。印度电视台对此次发射进行了现场直播,但在发射之后19分钟,本应进入轨道的卫星却出现了问题,导致发射活动最终失败。

此次发射是IRNSS-1H卫星是印度区域导航卫星系统中的重要一员,重1.4吨,是首颗由印度私营部门制造的定位导航卫星,原本用于取代印度此前发射的一枚定位卫星。据印度航天部门透露,此次发射失败并非发动机问题,而是卫星整流罩在上升过程中分离失败,导致卫星被封闭在整流罩内无法释放到轨道中。

印度区域导航卫星系统(IRNSS)是印度研发的区域型卫星导航系统,可视作是印度版的北斗导航系统。该系统主要提供两种服务,包括民用的标准定位和军用的限制性服务,一共包括7颗卫星,号称能够对印度及其周边1500公里范围内的用户进行精确制导和定位授时,据报道在印度本土的定位精度为10米以内,其他地位则是20米以内。

印度发展本国的区域卫星导航系统目的很简单,就是摆脱对美国GPS卫星导航系统的依赖,确保本国精确制导武器的安全性,虽然印度军队之前与美俄签署了有关GPS和格洛纳斯导航的合作协议,但是印度认为敏感军事信息掌握在国外手中并不安全,因此不惜斥巨资打造国产卫星导航系统。此次发射失败也将对印度发展国产卫星导航系统带来不利的影响。
