Open index.html from any HTTP/HTTPS server. Opening from file:// won't
work — OSM tiles and the stations.json fetch both need a real HTTP origin.
python3 -m http.server 8000
# then open http://localhost:8000Or enable GitHub Pages (Settings → Pages → main branch → / (root)) for a
hosted version.
A scheduled job fetches sourcetables from every configured
caster multiple times a day, parses STR lines, drops
DGNSS-only and VRS streams, and commits the result to
data/stations.json on main. See
docs/rtk_inventory.md for every endpoint, credentials,
and audit trail of what was investigated.
We did, then we got shadow banned ("flagged") by a Github robot and the manual review process took over 2 weeks to respond. Access is now restored until it isn't, so we're staying with the Github-independent host for now.
Station coordinates, mountpoint names, formats, and constellations are
republished from each operator's NTRIP sourcetable. Where the operator's
