Guardian — Release Notes

This page lists updates, improvements, and fixes for Guardian.

Version 1.0 — Launch Release

Release Date: June 2026

First public release of Guardian. Establishes the core space weather, propagation, and signal-environment situational-awareness dashboard for operators, communicators, educators, preparedness users, and technical professionals.

Space weather dashboard:

  • NOAA/SWPC-powered data integration — Kp index with G-scale, solar flux index (SFI), sunspot count, solar wind speed and density, IMF Bt/Bz
  • Aurora status with A-index and estimated equatorial boundary
  • D-RAP ionospheric absorption display (High/Low/None with HAF reference frequency)
  • Particle flux monitoring — proton flux ≥10 MeV and electron flux >2 MeV
  • Radio blackout forecast — R-scale probabilities for next 24 hours
  • Solar flare probabilities — C-class, M-class, X-class, and proton event percentages
  • Kp index bar chart showing 3-hour values across today’s forecast window
  • Radiation event tracking with 3-day probability outlook

HF propagation and signal conditions:

  • HF band conditions table — 160m through 6m, day and night columns
  • MUF and foF2 heuristic reference indicators
  • GIRO noted as an ionospheric-data reference
  • Band conditions derived from current SFI, Kp, and solar-flux data

Satellite tracking:

  • ISS and CSS always-on tracking with AOS/LOS and in/out-of-view status
  • SAT 1 and SAT 2 optional overlays with footprint rings and orbit trails
  • Custom satellite entry by NORAD ID or TLE paste
  • CelesTrak automatic lookup by NORAD ID
  • Satellite tooltips with full orbital parameters

Local reference context:

  • Local reference location entry — callsign if desired, latitude/longitude, city, state
  • All satellite visibility computed relative to the selected local reference location, also called DE or QTH by radio operators
  • Sunrise/sunset times for the selected location
  • Moon phase display
  • Local weather at the selected location: temperature, humidity, wind

Custom ticker:

  • Up to 5 configurable public RSS/XML feed URLs
  • Adjustable scroll speed
  • Custom text entry for local notes, reminders, or operational messages

Operational design:

  • Provider safety governor — automatic fallback when NOAA/SWPC feeds are unavailable
  • CelesTrak provider safety with embedded TLE fallback
  • Feed-status indicator showing freshness of all data sources
  • Local-first: last-good space weather values remain displayed when connectivity drops
  • In-app Help overlay and Info panel with keyboard shortcuts
  • Full-screen browser-based interface — Chrome, Edge, Firefox, Safari on Windows, macOS, Linux
