We conduct detailed feasibility studies to evaluate the technical and economic viability of space missions, including orbital analysis, payload accommodation, and mission duration assessments. Our compatibility analysis focuses on the integration of various subsystems and components, ensuring compliance with interface standards and electromagnetic compatibility (EMC) requirements. We utilize reliability engineering techniques, such as Reliability Block Diagrams (RBD) and Monte Carlo simulations, to predict system performance over the mission lifespan. Our analyses identify potential single points of failure and provide recommendations for redundancy and robustness improvements. By applying standards like ISO 26262 and NASA’s reliability guidelines, we enhance mission assurance and reduce the risk of in-orbit failures.
