SPACSSIM: Simulation and Analysis Software for Mathematical Modeling of Satellite Position and Attitude Control Systems

This article presents software for a satellite position and attitude control system based on mathematical modeling. The software is developed using Matlab for conceptual design; an added benefit is that it shortens design time and decrease design costs. Providing interactive modules for different actuators with various configurations and control algorithms makes this toolbox suitable for analyzing the effect of design parameters on satellite response and stability. Moreover, this toolbox contains adjustable modules for date and orbital parameters, which helps users improve their realization of satellite position effects on different matters such as eclipse, magnetic field, and satellite communication with ground station. Taking position data, the software computes disturbance torques and gives users the ability to analyze satellite attitude control performance. The software's ability to show simulation results as a set of graphics and text windows makes it more user friendly.
