# When the Light Is No Longer Visible: IALA L1.4 and Expanding AtoN

Language: `en`
Story type: `research_note`

## Narrative Angle

The IALA L1.4 GNSS and e-Navigation course in Constanța (14–18 Sep 2026) is kept as contemporary maritime context for an open question: what still counts as AtoN or “lighthouse” when physical light, AIS, virtual AtoN, GNSS/PNT, and digital services share the work of making space readable — without treating the course as a Heritage Journey target.
