Reliability assurance of satellite components is crucial for mission success, as in-orbit failures can lead to significant operational and financial risks. This paper introduces the design, development, and validation of the Satellite Component Reliability Management System (SCRMS), which integrates comprehensive data analysis and predictive modeling to enhance reliability assessments. SCRMS consolidates component specifications, application details, and in-orbit performance data into a structured database, facilitating real-time monitoring and reliability evaluation. Utilizing a browser/server (B/S) architecture, the system offers scalability, ease of access, and low maintenance overhead, aligning with the operational demands of modern satellite projects. Key functionalities include component data management, quality assurance tracking, failure mode analysis, in-orbit status monitoring, and reliability prediction based on stress modeling. Extensive testing validated the system’s stability, accuracy, and efficiency, maintaining optimal performance under load conditions. By enabling comprehensive risk assessments, SCRMS provides critical insights for optimizing component selection, material choices, and manufacturing processes in satellite design, contributing to improved mission reliability and longevity.
