Implementation of a Communication Satellite Orbit Controller Design Using State Space Techniques

Satellites offer the unique possibility of interconnecting users, regardless of their location or distance, and providing a complete spectrum of telecommunication services regardless of bandwidth requirements (Richharia & Westbrook 2011). A satellite also needs a guidance system to make sure that it maintains the proper angle in relation to the earth. Communications satellites, weather forecasting satellites and remote-sensing satellites all have different subsystems. These spacecraft require major subsystems. They are the propulsion subsystem, thermal control subsystem, power supply subsystem, telemetry tracking and control subsystem, and altitude and orbit control subsystem. A satellite is launched into its approximate desired orbit by a large rocket, which may be carrying several satellites at the same time. Once a satellite is launched into a desired orbit, it never remains in this ideal Implementation of a Communication Satellite Orbit Controller Design Using State Space Techniques
