TABLE 4.2 Space Vehicle Avionics Technology Gaps Across the NASA Roadmaps

Avionics Technology Gap Area Limits of Draft Roadmaps
Processing Speed and Data Throughput High-performance computing is mentioned in TA 11 as a flight computing technology, but only based on use of multi-cores as a technical approach.
Discussion of data bus technology is absent except for (1) TA08 under Wireless Spacecraft Technologies and (2) wireless and optical networks addressed in TA 13 under Safety Systems technology.
Radiation Tolerance In TA10, there is passing reference to possible radiation-tolerant benefits of nanomaterial-based electronics.
In TA11, only integrated circuits are identified as needing radiation-hard capabilities (as Flight Computing technology).
Reliable, Fault-Tolerant Processing This area of interest is superficially mentioned in the TA11 under Flight Computing technology where it is addressed solely in the context of multi-core processing.
Fault Management This area is not consistently identified across the draft roadmaps where these technologies are applicable.
Integrated Capabilities This area is only superficially mentioned in TA08 under Electronics technology.

Finding. Crosscutting Technologies. Many technologies, such as those related to avionics and space weather beyond radiation effects, cut across many of the existing draft roadmaps, but the level 3 technologies in the draft roadmaps provide an uneven and incomplete list of the technologies needed to address these topics comprehensively.

Recommendation. Crosscutting Technologies. OCT should review and, as necessary, expand the sections of each roadmap that address crosscutting level 3 technologies, especially with regard to avionics and space weather beyond radiation effects. OCT should assure effective ownership responsibility for crosscutting technologies in each of the roadmaps where they appear and establish a comprehensive, systematic approach for synergistic, coordinated development of high-priority crosscutting technologies.
