Space weather & positioning outlook
Quiet — forecast Kp 3. The ionosphere is calm; no space-weather impact on RTK expected this week.
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 7.3.
Measurement series: continuous since 2026-07-03 · 4 days · 1,113,430 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.
