RTK Base Station List Community RTK Stations

Every public RTK base station we can find, polled every 10 minutes. Position, format, authentication, fee and 30-day uptime — and an open list your receiver can read by itself.

The record we keep

What grows here is the availability record of the community RTK network: every 10 minutes we ask each caster which stations are alive, and we keep that answer. Nobody else keeps this history, and a missed 10 minutes can never be re-observed. We do not store raw RTK correction data (RTCM) — that recording stopped in July 2026; what was already collected is kept permanently.

Richness score (0–12): computed from each station's RTCM message set — MSM7 +3 / MSM5·4 +2, +1 per supported constellation (GPS/GLO/GAL/QZS/BDS), station coordinates (1005/1006) +2, high-grade receiver +1. It is a record of what is broadcast, not a judgement of station quality (the optimal set depends on use). ※ Formerly “sensitivity” — renamed to “richness” to reflect the richness of the broadcast messages, not receiver sensitivity (2026-07). Uptime is hidden until at least 7 days of measurement (so the number is fair).
Uptime: the observation rate of our sourcetable health checks, done every 10 minutes (measurement started 2026-07-03, up to a 30-day window, still accumulating).
To station operators: Listings are based on each caster's public sourcetable. Base stations are community assets run on volunteers' goodwill — this board exists to make that contribution visible. For corrections or removal, email 369@kotaroasahina.com (we respond promptly).
