For few researches has been done on satellite jitter and its 
manifestation in images, property of the jitter in Beijing-1 small 
satellite has to be achieved via assumptions and experiments, 
thus leading to the solution. The jitter removal method brought 
up here has been tested with various data sets and is proved to 
be effective, besides, its adaptiveness in large image treatment 
and batch processing facilitates the application in industrialized 
production process.

5. CONCLUSIONS 
High resolution imaging requires attitude of the satellite to be 
extraordinarily stable. Small satellite, owning to the small 
inertia, is hard to keep still under outside disturbance. Usually, 
extra dumper is fixed onboard to counteract the affection. Even 
so, jitter that can not be eliminated by the attitude compensation 
devices still exists. Ground image processing methods have to 
be resorted to remove the jitter.
