The basis of dynamics and simulation includes the iterative flyout angle algorithm to the solutions to lambert problem and battin ' s universal conic section state extrapolate method. then spacecraft ' s orbit roots, maneuver impulse and maneuver time are discussed as the following four part : first of all, the chaser ' s one orbit roots is selected as a variable to simulate its influence to the large scale orbital maneuver. the research reveals fact that the orbit roots both of chaser and target should be close to each other to achieve better maneuver and rendezvous " ability, moreover, the best orbit maneuver and rendezvous occurs when both chaser and target ' s initial phase angle are equal
為了研究了交會機動中追蹤器和目標器的軌道根數、機動時限和機動能耗等因素對交會機動的影響，模擬和分析分為以下四個部分:首先，研究了追蹤器軌道單個參數為變量情況下兩航天器大范圍交會機動問題，研究表明，追蹤器的變化參量與目標器相應的參量在接近的情況下可以獲得良好的交會機動特性，而對于兩航天器軌道共面的情況下，初始相位角相等時則獲得最佳的機動效果。 -
In the first part of this paper, different kinds of usual network architecture of parallel - processing multi - processors are studied. based on adsp - 21160 serial digital signal processors from ad company, close - coupled flexible hardware network architecture is selected as the network architecture of the system, because of which the hardware logical architecture of the system can be recomposed on line according to the acquirement of different algorithms
本文第一部分研究了各種常見的并行處理網路結構，基於ad公司的adsp - 21160系列數字信號處理晶元，選擇緊耦合的柔性硬體結構作為該系統的并行處理結構，使得系統的硬體邏輯結構可以根據演算法的要求在線重組。
