KUON GEO

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.

2,000+ stations tracked — online now — in Japan 10min polling interval
KUON MAP showing community RTK base stations across Japan with 10 km and 20 km coverage circles

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 sensitivity score for every station, free of charge.

RTK base stations plotted worldwide with online and offline status on KUON MAP

Every community base station, live

Green means online, red means offline — refreshed continuously from public sourcetables. Zoom in for 10 km (cm-grade) and 20 km (practical) baseline circles, click any station for copyable NTRIP connection details.

Centimeter-scale RTK NMEA log track plotted on KUON MAP

Plot RTK logs at 1 px ≈ 1 cm

Drop .log / .nmea 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.

Point weather measurement with temperature, wind and pressure on KUON MAP

Weather that matters to GNSS

Radar with KUON's own short-term nowcast, temperature and pressure fields, wind streamlines — click anywhere for point conditions. Built by a team that archives GNSS data for atmospheric research.

Route planning with walking, cycling and driving times on KUON MAP

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 showing live GNSS satellites around Earth

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 webcams layer on KUON MAP

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.

Run a base station? This is for you.

Every station gets a permanent page with a 60-day uptime heatmap and a live badge — free, updated every 10 minutes. Embed it in your blog, forum signature or README. Community base stations are a public good; this board exists to celebrate them. Everything shown is a record of public information and our own observations — never a judgement of your work.

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 sensitivity 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 also archive raw GNSS data every day for atmospheric research (precipitable water vapor, snow sensing).
