Meta-repo for HELIOS — 577 Industries' NASA SBIR Phase I program on calibrated space-weather decision intelligence (subtopic SPWX.1.S26A). Hosts the public proposal companion document, master plan, cross-repo orchestration scripts, and per-artifact design specs that coordinate the four HELIOS artifact repositories.
The submitted NASA SBIR Phase I proposal "HELIOS: Heliophysics-Enhanced Location Integrity and Operations System" advances a model-agnostic Bayesian-Model-Averaging fusion layer for space-weather model outputs, with two vertical slices (NASA SRAG mission-operations radiation risk and U.S. precision-agriculture GNSS). This meta-repo coordinates the public artifacts that back the proposal's claims with live, citable code.
git clone --recurse-submodules https://github.com/577Industries/helios-program.gitThis umbrella repo bundles the 4 public HELIOS artifacts as git submodules pinned at their latest release tags (see submodules/). Each submodule is independently usable from its own repo URL.

Phase-II-ready (2026-05-18). All 4 public HELIOS artifacts have shipped initial releases and are bundled here as submodules. Phase II evidence assembly lives at phase-ii/. Four dispatch-ready specs in specs/ cover Sprint D kill-gate, TFT-TEC forecasting, the arXiv preprint, and Phase II evidence refresh. See plan/master-plan.md § Execution Log for the rolling state.
