低轨飞行跟踪控制有2种模式:已知运行轨迹的运行情况跟踪和随动飞行器跟踪.对已知运动轨迹的飞行器跟踪,主要是获取飞行器的运行轨迹参数,用以判断飞行轨迹是否偏离原来的设定,通过调节接收器的跟踪位置以获取传输的数据;随动跟踪的运行轨迹未知,跟踪算法和设备状况有关,控制过程算法要求高.就一跟踪系统对已知轨迹低轨飞行器的跟踪控制算法模型进行了设计,在应用上取得了较好的效果.
低軌飛行跟蹤控製有2種模式:已知運行軌跡的運行情況跟蹤和隨動飛行器跟蹤.對已知運動軌跡的飛行器跟蹤,主要是穫取飛行器的運行軌跡參數,用以判斷飛行軌跡是否偏離原來的設定,通過調節接收器的跟蹤位置以穫取傳輸的數據;隨動跟蹤的運行軌跡未知,跟蹤算法和設備狀況有關,控製過程算法要求高.就一跟蹤繫統對已知軌跡低軌飛行器的跟蹤控製算法模型進行瞭設計,在應用上取得瞭較好的效果.

LEO (low earth orbit) aircraft tracking control has two models,tracking control with known trajectory and with dynamic trajectory. The former is using the trajectory parameters of aircraft to judge whether the trajectory diverges from the original design. The transmitted data are obtained by adjusting the tracking place of reeeiver. Because the trajectory of dynamic tracking is unknown,tracking algorithms are related to the situation of the equipment and the controlling process algorithms have high requirement. A tracking control algorithm model for known trajectory under tracking system was designed and it achieved good ap- plication effect.
