HELIOS

Heliophysics-Enhanced Location Integrity and Operations System

Calibrated, provenance-tracked decision intelligence that fuses NASA and NOAA space-weather model outputs and translates them into the specific operational decisions two user communities act on: NASA mission operations (SRAG SEP all-clear revocation) and U.S. precision agriculture (equipment-specific RTK accuracy maps). Not a new model — a model-agnostic fusion layer with feature-level provenance.

1,302 station-hours of RTK error exceeding the 2.5 cm planting threshold across 25 NGS CORS stations in IA / IL / IN / OH during the May 10-12, 2024 Gannon G5 storm.
First reproducible quantification. v1 climatological model — full SPP refinement in v2 via the CDDIS adapter (in flight).

Phase I artifacts

Four public repositories + one private companion convert the submitted-proposal claims into citable, reproducible URLs. Status reflects the most recent tagged release; see footnotes.yaml for the machine-readable registry.

Dependency graph

Artifact A (provenance schema) is the foundation; B (connectors) and C (fusion engine) consume it. C also consumes B's normalized data. D (Gannon retrospective) is independent today but will consume B's CDDIS adapter in v2 for full SPP solutions. F (private weights companion) ships trained priors fitted on Table 3-1 events.

Wave 2 dispatch (in progress) adds 5 more connector adapters to B: NOAA SWPC, GOES, DSCOVR (Wave 2a — DONKI-pattern-similar), then SEP Scoreboards A/B/C and CDDIS GIMs (Wave 2b — complex). Sprint C-Training begins once B v0.2 ships with real Scoreboard A flow.

About this site

This is the public landing page for HELIOS — 577 Industries' NASA SBIR Phase I program (subtopic SPWX.1.S26A) on calibrated, provenance-tracked space-weather decision intelligence. The submitted proposal mirrors here as the Proposal Companion with live citations to every public artifact. The Master Plan has the dependency graph and execution log.

Reading order for first-time visitors:

  1. The Proposal Companion — what HELIOS does and why it matters for both NASA mission ops and U.S. precision agriculture.
  2. The Master Plan — how the program is structured, the pre-registered validation discipline, the Wave 1 → Wave 2 execution log.
  3. Whichever artifact card above matches your interest.
  4. The Operations Guide — practical runbook for operators and Claude sessions joining the program.

For deep technical context on each Wave 1 artifact, see the per-artifact Review Packs in the nav.

Status snapshot

  • Wave 1 (foundation): A v0.1.0 RFC, C v0.1.0 framework, D v0.1.0 retrospective shipped 2026-05-17. B foundation + DONKI shipped; v0.1.0 alpha held until ≥3 adapters live (per master plan).
  • Wave 2 (in flight): three sub-wave-2a adapter agents (SWPC, GOES, DSCOVR) in parallel; sub-wave-2b (SEP Scoreboards + CDDIS GIMs) follows once 2a merges.
  • Sprint C-Training (future): blocked on B v0.2.0 (full connector suite live) + OSF pre-registration filing.
  • Kill-gate evaluation (future): blocked on Sprint C-Training + pre-reg.

See the Master Plan execution log for the rolling status.
