任务简介

高分系列是中国高分辨率对地观测系统（CHEOS）开发的民用地球观测卫星，该系统是由国家资助的计划，旨在建立一个由卫星、临近空间（平流层）飞艇和航空观测平台组成的近实时、全天候全球监测网络。基于SAST5000B平台，高分五号将搭载六种有效载荷，包括可见光与短波红外超光谱相机、光谱成像仪、温室气体探测器、超高光谱分辨率大气环境红外探测器、大气痕量气体差分吸收光谱仪以及多角度偏振探测器。卫星设计寿命为8年。它将由长征四号丙运载火箭发射至705公里太阳同步轨道（SSO）。

原文

Gaofen is a series of civilian Earth observation satellites developed and launched for the China High-definition Earth Observation System (CHEOS), a state-sponsored programme aimed to develop a near-real time, all-weather, global surveillance network consisting of satellite, near-space (stratosphere) airships, and aerial observation platforms. Based on the SAST5000B bus, Gaofen 5 will carry six types of payloads, including visible and short-wave infra hyper-spectral camera, spectral imager, greenhouse gas detector, atmospheric environment infrared detector at very high spectral resolution, differential absorption spectrometer for atmospheric trace gas, and multi-angle polarization detector. The satellite has a designed life of 8 years. It is to be launched atop of a Long March 4C to a 705km Sun Syncronous Orbit (SSO).
