The live map of the world's
community RTK base stations.
Free · token-less · in your browser. Live status and cm-grade coverage of community NTRIP stations, weather radar nowcast, and centimeter-scale RTK log plotting: on one map.
KUON GEO monitors 2,000+ community RTK base stations across four public NTRIP casters: RTK2GO, BizStation (Japan), GeoRTK (Japan) and Centipede-RTK: polling every 10 minutes, and publishes live status, uptime history and a 0–12 richness score for every station, free of charge.
In spirit, KUON GEO is the Organic Maps of GNSS: a map is a tool, not a territory to harvest. No account, no ads, no third-party trackers, and we never follow you. Only measured facts.

Every community base station, live
Green means online, red means offline: refreshed every 10 minutes from public sourcetables. Zoom in for 10 km (cm-grade) and 20 km (practical) baseline circles, click any station for copyable NTRIP connection details.
Plot RTK logs at 1 px ≈ 1 cm
Drop .log / .nmea / .ubx files onto the map and stack multiple tracks as layers. Zoom to level 24 where one pixel is roughly one centimeter: see what your rover actually did.
Weather that matters to GNSS
Radar with KUON's own short-term nowcast, temperature and pressure fields, wind streamlines: click anywhere for point conditions. Radar and fields are live proxies, not stored: we stopped archiving raw weather in July 2026 because the sources keep it themselves.
Routes, measurement, coordinates
A→B routing with walk/bike/car times, geodesic distance measurement between RTK points, and a coordinate reticle that reads DMS, UTM, MGRS, Plus Codes and ECEF in real time.
KUON ORBIT: the sky, live
Watch GPS, GLONASS, Galileo, BeiDou, QZSS and the ISS orbit in real time (SGP4 propagation), with QZSS drawing its figure-eight over Japan. The satellites your rover hears, made visible.
Live cameras & more
Curated live cameras around the world, day/night terminator, six languages for map labels: small things that make one map feel like the whole planet.
🧰 Free GNSS tools: no account, in your browser
Convert and inspect GNSS data right in your browser: raw logs to RINEX, a RINEX viewer and quality check, Hatanaka compression, and track conversion to GPX/KML/GeoJSON. Built for surveyors, precision-agriculture, drone and robotics developers.
FAQ
What is KUON MAP?
A free, browser-based map combining community RTK base stations (live status + coverage), weather radar nowcast, cm-scale RTK log plotting, routing and satellite tracking. No account, no API token.
Which networks are monitored?
RTK2GO, BizStation (Japan), GeoRTK (Japan) and Centipede-RTK (worldwide): public sourcetables polled every 10 minutes.
How is the richness score calculated?
From each station's RTCM message set: MSM7 +3 / MSM4·5 +2, one point per GNSS constellation (GPS/GLO/GAL/QZS/BDS), +2 for station coordinates (1005/1006), +1 for a high-grade receiver. Maximum 12.
Can I get my station removed or corrected?
Yes: email 369@kotaroasahina.com and we respond promptly. Listings are based on public NTRIP sourcetables.
Who runs this?
KUON GEO (Kuon R&D) in Obihiro, Hokkaido, Japan. We monitor the community RTK base-station network every 10 minutes and archive space weather, bear-sighting reports and weather warnings daily. We stopped recording raw GNSS (RTCM) in July 2026: the data already collected is kept permanently and never deleted.
