我国“高分二号”卫星9月19日顺利进入预定轨道,标志着我国遥感卫星进入了亚米级“高分时代”。这颗卫星系目前我国分辨率最高的光学对地观测卫星,空间分辨率首次精确到1米。600公里太空可辨地面汽车大小“1米分辨率意味着卫星从600多公里的太空向地面观察,能看见1米大小物体的轮廓,绝对能分辨出地面汽车的大小。如果是5米的分辨率就无法看清了,10米的分辨率只能看飞机大小的地面物体。”航天科技集
China’s “high score 2” satellite successfully entered its orbit on September 19, marking that China’s remote sensing satellite has entered the sub-meter “high score era.” This satellite is currently China’s highest resolution optical-to-earth observation satellite, the spatial resolution for the first time accurate to 1 meter. 600 kilometers of space can be discerned on the ground car size “1 meter resolution means that the satellite from more than 600 kilometers of space to the ground to see the outline of 1-meter-size objects, can definitely distinguish the size of the ground car .If it is 5 meters The resolution can not see, the resolution of 10 meters can only see the size of the aircraft ground objects. ”Space Science and Technology Set
