Distances are approximate antenna-to-station baselines. Nearest does not guarantee a working or optimal RTK fix. A network/VRS service can work differently from a single-base station.

Station map
Offline-capable coordinate diagram; north is up. Open individual stations in OpenStreetMap for a road map.
Optional live caster check
Browsers cannot directly authenticate and validate NTRIP/RTCM streams. You can connect an independently hosted HTTPS reachability checker (included in this package). It tests whether the caster responds, not whether your mountpoint is authenticated, streaming corrections or suitable for RTK.
Checker not configured; streams remain unverified.
Never enter NTRIP passwords here. Confirm mountpoint access and RTK Fixed status in SW Maps.
