摘要: |
针对灵巧成像卫星对地面目标观测摆角的计算问题,考虑地球自转和卫星在轨运动等约束,利用空间坐标变换建立了基于椭球体的空间运动学模型。在此模型的基础上,给出了任意时刻卫星对目标观测摆角的计算方法。仿真结果验证了方法的正确性。任意时刻观测摆角的获取为灵巧成像卫星任务调度提供支持。 |

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. |
Keywords: tasks scheduling agile imaging satellite observing angle modeling |
