We are developing an adaptive optics system for earth observing remote sensing sensor. In this system, high spatial resolution has to be achieved by a lightweight sensor system to be used for small satellites. Moreover, simple hardware architecture has to be selected to achieve high reliability and low development cost. Image based AOS realize these requirements without wavefront sensor. In remote sensing, it is difficult to use a reference point source unless the satellite controls its attitude toward a star. We propose the control algorithm of the deformable mirror on the basis of two methods; model-based wavefront estimation method and direct optimization of acquired images. We described simulation results of the proposed methods.
