摘要
为了提高太阳同步轨道卫星对GEO轨道带目标的观测效率,在分析观测位置和传感器视轴指向与太阳同步轨道卫星对静止轨道带扫描速度基础上得到传感器视轴的最佳指向以及对应的GEO带上的最佳观测点,并提出了关于最佳观测点的姿态规划策略,并对在地影影响下有/无姿态机动时的观测效率进行了对比仿真分析。仿真结果表明:对于SBV传感器视场在1.5°×1.5°时,最佳观测点的控制策略就能够完成对GEO轨道带的完全覆盖,相较于无姿态机动时,对静止轨道带的观测时间可提高一倍。
To improve the efficiency of the sunsynchronous satellite monitoring the GEO belt, the optimal point is found based on the relationship among the location for monitoring, the point direction of the sensor and the scan speed for the GEO belt. This paper presents an attitude maneuver strategy according to the optimal point and analyses the influence of the earth shadow on the surveillance efficiency . The results of simulation indicate that the sensor with a view field of 1.5°×1.5°can cover all the GEO belt controlled by the strategy and the surveillance efficiency can be improved over a time compared with that without an attitude maneuver.
