The aim of the Master Thesis is to develop a mission for interplanetary small-sats in support of the navigation of Martian rovers in the scope of the SINAV Project, sponsored by Italian Space Agency. The objective of SINAV Project is the development of High-Speed Autonomous Navigation Systems for future missions of robotic planetary exploration. In particular, the scientific-technological objectives and requirements that characterize this type of mission have been identified. Some mission architectures have also been defined and through trade-off it has been possible to identify the best architecture. This work presents an analysis of COTS components that can be used as optical payloads that meet mission requirements and that can be integrated into a small-sized structure that characterizes small-satellites.
