Paper Abstract

In the report we consider a method of dynamic aberration measurement in the frameworks of the problem of minimization of difference between potential and operational resolution of the earth observation satellite systems. The method is based on statistical analysis of the current image at the output of the image receiver. The results of the measurement are recalculated into control signals of the actuators in the adaptive feedback loop.
