1月9日11时17分,“长征四号乙”运载火箭在太原卫星发射中心点火升空,成功将我国首颗民用高分辨率光学立体测图卫星“资源三号”送入太空。同时,搭载发射了一颗卢森堡小卫星。“资源三号”卫星配置了三线阵测绘相机和多光谱相机,采用三线阵测绘方式生成立体测绘影像。三线阵测绘相机的前视、后视全色影像地面像元分辨率为4m,正视全色影像地面像元分辨率为2.1m;多光谱相机的正视多光谱影像地面像元分辨率为5.8m。“资源三号”卫星将提供高几何定位精度、高品质成像效
At 9:17 on January 9, “Long March IV B” rocket landed at the Taiyuan Satellite Launch Center and successfully delivered China’s first civilian high-resolution optical stereoscopic satellite “Resource No. 3” Into space. At the same time, equipped with a launch of a small satellite in Luxembourg. “Resource No. 3 ” satellite configuration of the three-line mapping camera and multi-spectral camera, the use of three-line mapping method to generate three-dimensional mapping images. The ground pixel resolution of front view and rear view panchromatic images of 3-line array camera is 4m, the resolution of ground pixel of frontal panchromatic image is 2.1m, the resolution of terrestrial multi-spectral camera with multi-spectral camera is 5.8m . “Resource No. 3 ” satellite will provide high geometric positioning accuracy, high-quality imaging effect
