The edges of the network
Furthest north: NYAWIPEV at 78.923°. Furthest south: TakiViewFarm at -46.14°. Most isolated: NKHR. The nearest other listed station is 1,484 km away, which is far enough that RTK between them would not hold.
Space weather & positioning outlook
Active to minor storm (G1) — forecast Kp 5. Ionospheric gradients may lengthen Fix times and affect long-baseline RTK; keep baselines short and expect occasional re-convergence.
Geomagnetic activity is a proxy for ionospheric disturbance; the actual effect on your RTK depends on baseline length, latitude and local conditions. Kp: NOAA SWPC (measured + forecast); recent 7-day observed max Kp 7.
Measurement series: continuous since 2026-07-03 · 102 days · 33,190,768 station observations.

Method
All numbers are direct measurements: KUON GEO polls the public NTRIP sourcetables of RTK2GO, BizStation, GeoRTK and Centipede-RTK every 10 minutes. Figures describe what stations broadcast — records, not judgements. See the station ranking, the KUON MAP, and the data & methodology.
