Abstract
The increasing demand for high-performance computer systems on board space missions applications, such as artificial intelligence and machine learning, are drivers of the need for higher on-board command and data handling specifications. Consequently, a modular Command and Data Handling Subsystem (CDHS) is required in order to manage the complexity of future CDHS hardware. Some systems have applied a similar approach; however, they either focus on large scale satellites or have a certain level of complexity that limits their usage by learners. This paper proposes a modular Command and Data Handling System that includes several layers providing more flexibility in design at a low cost. The system also potentially allows the integration of CDHS initially used in CubeSats in larger-scale satellites. Also, Through this paper highlights the interfacing options used in the proposed design, including the regular command and data interfaces, wireless command and data interfaces, high-speed data interfaces, and power interfaces. The results validate the usefulness and potential of the proposed system as a modular Command and Data Handling System that can be used in future missions. It also opens the door for further development, allowing the low-cost development of Command and Data Handling Systems.
