Satellite orbit determination and power subsystem design

One of the most important problems in mission planning and satellite command and control is being able to accurately predict orbital motion, because the trajectory of a spacecraft is a fundamental design parameter with major implications for all subsystems. The purpose of this paper is to present, first, the simulation of the satellite orbit analysis based on data collected from NASA/NORAD two line element files. The analysis includes orbit determination and prediction of satellite position/velocity, orbit eclipse and ground trace and so on. Second the application of this simulation to design the low Earth orbit (LEO). The intention of this simulation was to create a graphical User Interface GUI which consists of menus, push buttons, text boxes, plots and other interface devices that allow the GUI user to immediately see the impact of various changes.
