| Abstract: | The problem of computing the observing angle of an agile imaging satellite was discussed.Considering the constrains of the earth rotation and the satellite moving on its orbit,the kinematic model based on ellipsoid was established by means of space reference frame transformation.Based on this model,the algorithm for computing observing angle at any given visible time was proposed.The results show the efficiency of our approach.The acquired observing angle supports the task scheduling of agile imaging satellite. |
