A fast algorithm for imaging time window prediction of optical satellites consider- ing the J2 Perturbation was represented. An imaging condition equation about eccentric anomaly is drawn based on a simplified feature cone model. In order to solve the transcen- dental equation by Newton iteration, a hybrid method for initial value selection was presen- ted in detail. A latitude circle was exploited to potential initial acquisition, and the character- istic of periodic drift of sub-satellite point was utilized for the initial value filterin...
