摘要：By contrast to one on low earth orbit(LEO),high spatial resolution optical imaging earth observation satellite on geostationary orbit has some remarkable advantages with much higher time resolution,more wider imaging field、much longer target tracking and monitoring time,and now is becoming one of important development foucs. Corresspondently GEO optical imaging satellite has much higher control accuracy requirement with stability than LEO, greatly promote development difficulties.The paper makes dicussion for key structure influence factors on attitude & structure stability for image quality guarantee under complex space circumstance and conducts stimulation to account for the their effect,finally present some solution options.
