北京时间2015年7月11日,前3颗灾害监测星座-3(DMC-3)—北京-2星座由印度极轨卫星运载火箭-C28(PSLV-C28)发射入轨。这3颗卫星由英国萨瑞卫星技术公司(SSTL)研制,采用萨瑞卫星技术公司-300 S1平台,它们形成了一个新的星座—北京-2星座,其创新卫星设计具有巨大的成像潜力,每颗卫星携带有1m分辨率全色相机和4m分辨率三谱段成像仪,可以执行多种不同类型影像的拍摄任务,还能实现对地球给定区域的每日重访,这对用于变化监测、灾难监测和响应规划至关重要。
Beijing On July 11, 2015, the first three Disaster Monitoring Constellation-3 (DMC-3) -Beijing-2 constellations were launched into orbit by the Indian polar orbiting satellite carrier-C28 (PSLV-C28). Developed by SSTL and using the -300 S1 platform from Saturn Satellite Technologies, these three satellites formed a new constellation, the Beijing-2 constellation, with an innovative satellite design that offers tremendous imaging potential, Each satellite carries a 1m resolution panchromatic camera and a 4m resolution three-band imager that can perform a variety of imaging tasks for different types of images and also enables a daily revisit of a given area of the Earth, Variance monitoring, disaster monitoring and response planning are crucial.
