Høypresisjons punktposisjonering (PPP) i skyen

Last opp RINEX-data fra en basestasjon eller rover og motta nøyaktige ITRF/WGS84-koordinater korrigert for atmosfæriske forsinkelser.

Processing needs an account. This panel is a first step: it checks your file and needs no account.

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.

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 compute precise point positioning (PPP) online

Process single-station RINEX observations and review the PPP solution, processing settings and quality indicators.

  1. Upload observation session

    Upload RINEX observations with the signals, time coverage and station metadata required by the selected processing mode.

  2. Select antenna model and height

    Specify antenna model from the absolute calibration database and enter antenna reference point (ARP) height.

  3. Automated ephemeris pairing

    The system pairs matching IGS, CODE, or GFZ final/rapid precise orbits and satellite clock corrections.

  4. Solve and download coordinates

    Review converged coordinates in ITRF/WGS84, formal standard deviations, residual plots, and processing reports.

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 short or discontinuous static observation session

A long enough, uninterrupted observation window. PPP resolves ambiguities through convergence, and a short or frequently broken session may never converge on a stable coordinate.

A session with frequent cycle slips

Continuous carrier-phase tracking. Repeated slips reset the convergence the solution depends on, the same way restarting a session would.

Single-frequency-only observations

Dual-frequency (or better) tracking. A single frequency carries no way to form the ionosphere-free combination the solution needs to cancel that delay.

Common questions

Hva kreves for en statisk PPP-beregning?

Du trenger bare å laste opp RINEX-observasjonsfilen fra én tofrekvent mottaker. En lokal basestasjon er unødvendig fordi posisjonen beregnes mot globale presise satellittbaner.
