In the early years of the Space Era, rudimentary data processing units supported the control of all electronic and electromechanical units in satellites. Starting with the first sounding rockets and satellite launchers, analog computers were present in the evolution of space systems. Space systems have different requirements than the ordinary electronics. The mission requirements and the operational needs define the framework of the spacecraft system. The system architecture shows the interaction of the system units and is illustrated in a block diagram. Several system architectures are available and can be implemented depending on the system requirements. In order to comply with the mission requirements, it is necessary to dimension the on‐board computer with the mission processing and storage needs. For the design of the on‐board computer, the data budget gives relevant information for the calculation of the On‐Board Computer resources.
