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.

How to perform GNSS baseline network adjustment online

Adjust multi-station GNSS baseline networks with rigorous least squares estimation in 4 steps.

  1. Upload simultaneous observation files

    Submit RINEX observation files from two or more stations observing over an overlapping time span.

  2. Select adjustment strategy and reference constraints

    Choose Network I or Network II, select fixed control stations or minimal constraints, and configure elevation cutoffs.

  3. Execute least-squares adjustment and loop closure

    The cloud engine forms double-difference baselines, screens cycle slips, computes loop closures, and estimates coordinates.

  4. Review uncertainty reports and export SINEX

    Examine residual plots, coordinate uncertainties, and standard deviation estimates, then download standardized SINEX deliverables.

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.

A single station's observations, with nothing else submitted alongside it

At least two stations observing simultaneously. A network adjustment distributes closure error across baselines, and there is no network with only one station.

Stations in the set with no common observation window

A time span where the submitted stations were all logging together. A baseline can only be formed for the overlap, and no overlap at all leaves nothing to include.
