“…The general principle of the FMECA consists of analyzing the behavior of the system parts, concurrently with components failure, mainly aiming at verifying the design. In space engineering, this general principle has been pursued in the Apollo program in the mid-1960s [7] and, later on, in a wide number of satellite applications (see, e.g., [8][9][10][11][12][13][14][15][16][17], detailed in the following paragraphs).…”

“…Traditionally, the available literature on FMECA reveals a hardware-oriented perspective. See (e.g.,) the risk analysis performed for lithium-ion battery design of a hybrid satellite in geostationary orbit developed in Korea based on the EUROSTAR 3000 platform [9], the analysis of key components of circular truss antenna, mainly detailing the criticality related to the hinge mechanism [10], or the reliability study of the power distribution module UYGAR [11]. The FMECA can be interfaced advantageously with other reliability and quality analyses by adopting a Total Quality Management (TQM) perspective, as acknowledged by the Department of Defense [12].…”

Besides large-scale space missions, the spread of CubeSats for a variety of applications is increasingly requiring the development of systematic approaches for risk management. Being these applications are based on components with low TRL (Technology Readiness Level) or with limited performance data, it is required to define approaches which ensure a systematic perspective. This paper aims to present a reliability engineering approach based on FMECA (Failure Mode, Effects, and Criticality Analysis) to manage CubeSat reliability data and prioritize criticalities early in the design phase. The approach firstly proposes an alpha-numeric coding system to support the identification and labeling of failure modes for typical CubeSats’ items. Subsequently, each FMECA coefficient (i.e., Severity, Occurrence, Detectability) has been linked to the CubeSat’s structural properties, reducing subjectivity by means of techno-centric proxy indicators. The approach has been validated in the design phases of a 6-Units university CubeSat for the observation of M-Dwarf stars and binary systems. The performed analysis supported the design process and allowed to identify the major criticalities of the CubeSat design, as demonstrated in the extended case study included in the paper. The formalized method could be applied to design procedures for nano-satellites, as well as being expanded for research and development in a variety of space missions.

European Space Agency (ESA) has addressed the key points like higher power demand and system efficiency, system reusability, adaptability and flexibility, decrease in system mass, size and cost, increase in modularity and standardization for the next generation (NG) power systems on future missions at 8 th Space Power Conference. Since the purpose of a power distribution module is to ensure reliable delivery of electrical power and prevent failure propagation, under all foreseeable conditions, during all mission phases, reliability and redundancy become critical issues in design. This paper describes UYGAR, which is the power distribution module designed in TUBITAK UZAY for Low Earth Orbit (LEO), Geostationary Earth Orbit (GEO) and Science Missions with its single point failure free, 100 kRad radiation tolerant and internally redundant electronic design while considering the key points addressed by ESA and the experiences gained in TUBITAK UZAY's previous satellite missions RASAT and GÖKTÜRK-2. This paper describes the high reliable, radiation tolerant, flexible, and unique design details compatible with ECSS-E-ST-20C and AIAA-S-122-2007 of NG power distribution module, UYGAR, which is considered as a part of higher power demanded and more complex power system architecture for next generation missions of various orbits. Moreover, the qualifications test results and details are presented.
