| 摘 要： | 随着遥感卫星分辨率的提高。星上微振动对空间相机的影响越来越显著。在相机与卫星平台之间安装隔振装置，将飞轮、扫描机构等扰振源产生的振动与相机隔离开来是一种改善其工作环境的有效方法。文章介绍了针对中巴地球资源卫星研制的相机被动隔振系统，以及在地面结构星上进行的联合隔振性能测试。测试结果表明。传递至相机的两个主要扰振频率分量... |

| Abstract: | Disturbances on a satellite bus can be a great enemy to high resolution space cameras by causing significant degradation to their image quality. An effective way to solve the problem is to isolate the payload from satellite bus using passive vibration isolators. A low frequency vibration isolation system was developed and demonstrated through system-level performance testing. Results showed that two of the primary frequency contents of the disturbances transmitting to the payload were attenuated by 96% and 98% respectively, and the image jitter was reduced to less than 0.5 pixels from 5-10 pixels. |
