TDI CCD 相机的卫星姿态稳定度确定
Confirmation of satellite attitude stabilization for TDI CCD camera
摘要
Abstract
To solve the image degradation caused by satellite platform vibration and to improve TDI CCD image quality, the range of satellite attitude stabilization and its effect were analyzed .First, the dependence of the satellite platform vibration on the TDI CCD image quality was discussed .Then, equations which gave the rela-tionship between image motion and attitude stabilization were derived .Finally, it was concluded that the satel-lite attitude stabilization was relevant to orbit altitudes and integral stages .The experiment results indicate that the higher the orbit altitude is and the bigger the integral stages are , the more rigorous the requirement of sat-ellite attitude stabilization is.From obtained data, it is demonstrated that when the orbit altitude changes from 200 km to 1 000 km, the requirement of satellite attitude stabilization need to improve from 0.037 7 to 0.006 35 rad/s.Meanwhile, when the integral stages change from 1 to 100, the requirement of satellite atti-tude stabilization need to be improved from 0.014 to 0.000 14 rad/s.The work in this paper confirms the re-lationships of satellite attitude stabilization , orbit altitudes and integral stages, which contributes to improve TDI CCD image quality.关键词
