Before you process, find out whether the data holds up.

Quick check, no account

Upload an observation file or open a sample to see its quality score and key findings.

One file up to 100 MB (20 MB gzipped), ten checks per day. The file is deleted as soon as the result is ready.

Quick question, so we know you are a person

Choose a file first

No file? Use a public station
Bundled sample

Opens a stored example result straight away and does not use one of your daily checks.

Live archive day

Fetches a station's daily observation file from the public archives and checks it. It needs the person check above and uses one of your daily checks.

Between 2010-01-01 and 2026-10-17 (UTC).

How to perform GNSS data analysis online

Quickly inspect and audit GNSS observation quality in 4 simple steps.

  1. Upload RINEX or raw log

    Upload any RINEX 2.x, 3.x, 4.x observation file or native receiver log (UBX, SBF, Trimble, Leica).

  2. Automated header and constellation parsing

    The system validates file structure, detects constellations (GPS, GLO, GAL, BDS, QZSS), and identifies signal frequencies.

  3. Run multi-frequency quality audit

    The cloud analysis engine computes epoch completeness, cycle slip counts, MP1/MP2 multipath values, and SNR distribution.

  4. Review quality score and export report

    Inspect the 0-100 composite score, review satellite skyplots and tracking charts, and export the findings as PDF or CSV.

What won't produce a result

Worth checking before you upload, so a run doesn't cost you credits to tell you what your data was missing.

Observation files without observation data records or invalid epoch headers

Standard RINEX observation records containing valid pseudorange and carrier-phase measurements for analysis.

Navigation-only ephemeris files uploaded without observation data

Raw observation files (.obs, .rnx, .crx) tracking satellite signal metrics over time rather than broadcast orbital ephemeris.

Non-standard proprietary binary formats without receiver decoding specifications

Standard RINEX observation format files, or supported multi-vendor raw binary logs.
