Abstract

fetched live from OpenAlex

HexPak is a deployable satellite structure that offers several advantages to small satellite missions, including ease of scalability, a geometry naturally adapted for plug-and-play architectures and multiple missionspecific component layouts, and a large deployed aperture from an optimal stowed volume. It consists of hexagonal bays that stack when stowed to efficiently use payload fairing volume, but deploy to a planar structure with deck area many times the fairing cross-section. The large deployed area to fairing size ratio supports large aperture payloads, multiple payloads, heat rejection significantly beyond traditional designs, multiple manifest with minimal wasted support mass, and easy access on orbit for expansion and flexibility for reconfiguration on orbit. For missions that require a large number of platforms, the modular structure offers easy interchangeability of HexPak bays which makes it possible to maintain a consistent production flow even during periods of parts shortages. Standard physical interfaces also allows for commonality in tooling, fixturing, testing and ease of satellite integration. The hexagonal geometry is near optimum for taking advantage of available faring envelopes and the folded structure is self-supporting, which minimizes the need for additional structure to support launch. Mission and subsystem design trades, including launch vehicle accommodation, structural design, layout and configuration are described.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
