8月19日11点15分,我国在太原卫星发射中心用长征四号乙运载火箭成功发射高分二号卫星,卫星顺利进入预定轨道。高分二号卫星是高分辨率对地观测系统重大专项中首批立项启动的项目,也是迄今中国研制的空间分辨率和寿命要求最高的民用遥感卫星,卫星具备高空间分辨率和大幅宽的成像能力,技术指标达到国外新一代卫星水平。卫星采用CS-L3000A平台,设计寿命5~8年,配置有两台相机组合而成的光学成像系统,具有全色/多光谱成像能力,实现高空间分辨率、多谱段对地观测。高分二号卫星星下点像元分辨率全色0.81m/多光谱3.24m,
At 11:15 on August 19th, China successfully launched the high-grade No. 2 satellite with the Long March IV B carrier rocket in Taiyuan Satellite Launch Center, and the satellite successfully entered the scheduled orbit. Highscatter II satellite is the first batch of projects launched in the major projects of high-resolution earth observation system and the civilian remote sensing satellite with the highest spatial resolution and life expectancy so far developed in China. The satellite has high spatial resolution and large width Imaging capabilities, technical indicators have reached a new generation of satellite levels abroad. The satellite uses the CS-L3000A platform and has a design life of 5 to 8 years. It is equipped with an optical imaging system composed of two cameras and has full-color / multispectral imaging capability for high spatial resolution and multi-spectral observation. Highscores on the 2nd satellite stars under the pixel resolution panchromatic 0.81m / multi-spectral 3.24m,
