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.
