KUON RINEX Viewer

Open a RINEX observation file and see satellite availability over time — free, no account, in your browser.

RINEX (.obs) is raw observation data used for survey post-processing. This viewer inspects its contents in the browser (like RTKPLOT) — it does not judge conversion accuracy. The file is processed only on this device and never sent anywhere.
Currently supports <b>RINEX 3.x</b> observation files (the converter default is 3.04). ← Convert .ubx/RTCM3/SBF to RINEX ・ KUON MAP
