Irrespective of the intended application, be it a communications satellite or a weather forecasting satellite or even a remote sensing satellite, different subsystems comprising a typical satellite include the following: mechanical structure, propulsion subsystem, payload subsystem and Antenna subsystem. The mechanical structure that holds the satellite and links it to the launcher is very important. Some of the important design considerations that need to be addressed while designing the mechanical structure of the satellite are briefly described in this chapter. The propulsion subsystem is used to provide the thrusts required to impart the necessary velocity changes to execute all the manoeuvres during the lifetime of the satellite. The thermal control system maintains the satellite platform within its operating temperature limits for the type of equipment on board. The power supply subsystem generates, stores, controls and distributes electrical power to other subsystems on board the satellite platform.
