摘要：Station keeping mode （SKM） for Attitude Orbit Control Subsystem （aocs）; it is an operational approach regarding the attitude dynamics control. The essential features of the design methodology is researching the basic theory and then afterwards, make an iterative design approach using some premise/assumptions, implementing the system simulation through the Simulink Matlab software package, designing the required controllers, monitor and analyzing the responses until the design give the best results within the range required. Firstly the thruster configuration is designed to acquire the parameters of the torque on the satellite. Next, the controllers are based on the well known PID control law. Controllers optimize the attitude and are used during the maneuvers for SKM. Afterwards the simulation results are given, and presented to demonstrate the performance and validity of the aocs design approach. Finally the simulation results demonstrate that all the requirements were accomplished and the Station Keeping Mode was successfully designed.

摘要：This paper has analyzed the perturbations of a GeoX-Sat （virtual satellite） in geostationary orbit （GEO）. And control methods, strategies and calculation processes are designed of the East-West （E/W） station-keeping of the GeoX-Sat. The Attitude and Orbit Control Subsystem （aocs） provides attitude information and maintains the required spacecraft attitude during all phases of the mission, starting at spacecraft separation from the launch vehicle and throughout its operational lifetime. For the GeoX-Sat exercising design, due to time limitations; only two modes of operation were considered after assumed launching operation： normal and station keeping.

摘要：PLANET－B是日本研制的第一颗火星探测器，对其姿态轨道控制系统（aocs）提出了行星探测器需具备的各种特殊要求。为满足这些要求，日本宇宙科学研究所和日本电气公司（NEC）以及NEC航空宇宙系统公司为该星设计了以太阳敏感器，星敏感器，反作用控制系统和星载计算机为核心的aocs，并完成了初样设计。
