摘要
＂高分二号＂（GF-2）卫星是高分辨率对地观测系统重大专项中为满足应用亟需和替代进口而规划的遥感卫星,也是中国第一颗目标定位精度要求达到50m、寿命要求达到5~8年、迄今为止中国研制的空间分辨率最高的民用低轨遥感卫星。文章分析了GF-2卫星高分辨率、高定位精度等任务的特点,以及高精度图像保障、扰振抑制设计、长寿命设计等技术创新点,并介绍了其在轨评价及应用情况,为后续高分辨率对地观测卫星提供了参考。
GF-2 satellite is the first satellite of Chinese importance special project for high resolution earth observation system, in order to meet the pressing need and substitute for imported remote data. It is the first remote sensing satellite of China with 50 m positioning accuracy and 5~8 years lifetime by design, especially, it has the highest resolution in China＇s civil remote sensing satellite at present. This paper introduces the characteristic of GF-2, include high resolution, high positioning accuracy and the innovations in high quality image design and vibration control design, long life design. Based on the on-orbit data, the primary accuracy and application of GF-2 are evaluated. This paper can be as a reference for other HR imaging satellite design.
