Public NTRIP and RTK station map

SurvSupport is a free, live map of public NTRIP correction stations worldwide — thousands of RTK base stations from RTK2Go, Centipede-RTK, EUREF-IP, the IGS, SAPOS and more, plus live tide gauges. We don't host any streams; we read each public caster's source table and show where its bases are.
