任务简介
TH 1（天绘一号，意为“天空绘图”）是一颗由中国解放军（PLA）运行的中国立体地形测绘卫星。 该卫星由航天东方红卫星有限公司、中国航天科技集团公司以及中国空间技术研究院（CAST）建造。卫星运行在500公里高的圆形太阳同步轨道上。电力由两块可展开的太阳能电池板提供，并储存在星载电池中。 卫星配备了一台三维测量相机和一台CCD相机，地面分辨率为5米，光谱范围为0.51微米至0.69微米，相机角度为25度。此外，还搭载了一台多光谱相机，地面分辨率为10米，工作在四个光谱波段：0.43微米至0.52微米、0.52微米至0.61微米、0.61微米至0.69微米和0.76微米至0.90微米。相机的幅宽为60公里。
原文
TH 1 (Tianhui-1 = "Sky drawing") is a Chinese stereo-topographic mapping satellite operated by the People’s Liberation Army (PLA). The satellites are built by the Hangtian Dongfanghong Weixing Corporation and the China Aerospace Science and Technology Corporation and the Chinese Academy of Space Technology (CAST). The satellites operate on a 500 km circular sun synchronous orbit. Electrical power is provided by two deployable solar panels that is stored on onboard batteries. They are equipped with a three-dimensional survey camera and a CCD camera with a ground resolution of 5 meters, spectral region of 0.51 µm to 0.69 µm and with a camera angle of 25 degrees. Also on board is a multi-spectral camera with a ground resolution of 10 meters operating in four spectral bands of 0.43 µm to 0.52 µm, 0.52 µm to 0.61 µm, 0.61 µm to 0.69 µm, and 0.76 µm to 0.90 µm. The swath width of the cameras is 60 kilometers wide.
