“东北 狗儿长大了原始”中国成功发射四东北 狗儿长大了原始维高景二号03、04星

  中新东北 狗儿长大了原始社北京11月25日电 (记者 东北 狗儿长大了原始马帅莎)据中国航天科技集团消息,北京时间11月25日7时39分,中国在酒泉卫星发射中心使用长征二号丙运载火箭,成功将四维高景二号03、04星发射升空,卫星顺利送入预定轨道,发射任务获得圆满成功。

  四维高景二号03、04星是中国四维新一代商业遥感卫星系统的两颗高分辨率雷达卫星,由中国航天科技集团八院研制。两颗卫星与中国四维此前发射的高分辨率光学、宽幅光学卫星组网运行后,将进一步提升国内领先的光SAR(合成孔径雷达)一体化服务能力,卫星系统将步入高效协作阶段。

  四维高景二号03、04星作为商业微波测绘卫星,可提供全天时、全天候、高分辨率雷达影像,主要服务于自然资源、城市安全、应急管理和海洋海事等多个领域。高分辨、高质量的雷达影像将有效支持中国基础测绘更新、农业生产和生态环境监测,可不受天气影响快速提取发生灾害范围,对洪涝、地质灾害等区域进行预警识别。

  长征二号丙运载火箭是由中国航天科技集团一院研制的常温液体运载火箭,是中国第一型“金牌火箭”,服役时间最长、用途最广、执行任务种类最多,主要用于发射低轨和太阳同步轨道卫星。这次任务是长征系列运载火箭的第547次飞行。(完)
