This section is titled "Small Satellites and Mission Architectures" and covers the various options for ... distributing sensors in orbit and the cost-effectiveness of smallsat architectures. It does not go into detail regarding mission architecture design but provides well-reasoned, high-level points and guidance with references to previous missions.
This guide describes procedures for conducting FMEA analysis. Functional, interface, and detailed FMEA ... are covered. It also includes pre-analysis items like FMEA planning and functional requirements analysis and post-analysis items like failure latency analysis, FMEA verification, and documentation. These procedures are provided with consideration for reliability, cost, and speed.
Mission environment and complexity for small satellites is becoming increasingly varied. Different missions ... will be more amenable to different risk and cost tradeoffs. These slides provide detailed information, considerations, and advice for EEE parts to be used specifically in smallsat missions. RHA, COTS use, and more are discussed.
These slides offer a discussion of EEE parts within the context of small spacecraft. Cost and reliability ... trade offs are at the core of this discussion, particularly in relation to parts screening and qualification methods. Alternate risk-mitigation approaches and the concept of "over-design" are also examined. Examples are provided.
This NASA Handbook is an extremely detailed source of technical knowledge regarding high reliability ... electrical and electronic component parts. Cost factors, screening techniques, radiation effects, derating, failure mechanisms, and much more is discussed.
The contents of this resource are the results of the National Research Council's Panel on Small Spacecraft ... Technology's review of NASA's technology development program for small spacecraft. Chapter 5 provides a concise review of common smallsat materials and their advantages and disadvantages. Structural and cost considerations are given.
This website is the primary source of information regarding the NASA Goddard Space Flight Center (GSFC) ... Radiation Effects Facility (REF). REF is located in Greenbelt, MD and supports TID testing for government, industry, and university customers. Their site includes points of contact for cost and scheduling, information on the various radiation sources (i.e. medium dose rate and ELDRS), and high-level experiment setup requirements.
This presentation provides background on the various TID testing methods widely implemented across the ... industry as well as an abridged summary of these test methods. This presentation goes on to make a case for updates to MIL-STD-883 Test Method 1019.9 in order to arrive at a technically correct and more cost-effective method. These details are summarized on Slide 24.
MIL-HDBK-217F Notice 2 is a widely used DoD resource which provides two methods for estimating the inherent ... reliability of electronic systems. The first prediction method, "Part Stress Analysis" in Section 5 through Section 23 is the more detailed and accurate of the two and is better suited for use in the later stages of a design. The "Part Count" method in Appendix A requires fewer inputs and is more appropriate for use during early design phases or while generating a technical proposal.
Thermal-vacuum testing is critical to ensuring satellite reliability and survivability. Unfortunately, ... many thermal-vacuum chambers are much larger than necessary for small satellites, resulting in an unnecessary cost burden for developers. This paper seeks to outline the methodology for developing thermal-vacuum chambers for testing small satellites.
