Baseline issue
This is the first weekly report — the baseline for every comparison to come. From next week, this section tracks how the network grows.
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 — they are records, not judgements. Explore every station on the live ranking board or the KUON MAP.
