Högprecisions satellitdatabehandling i molnet

Ladda upp råfiler eller standardiserade RINEX-filer; systemet matchar automatiskt exakta efemerider och levererar tillförlitliga 3D-koordinater.

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.

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.

Beräkningsmetoder som stöds

  • Precise Point Positioning (PPP): beräkning mot globala exakta banor utan lokal basstation
  • Post-Processed Kinematic (PPK): tvåfrekvens differentiell kinematik för drönare och fordon
  • Nätutjämning: gemensam minsta kvadratutjämning av multipla baslinjevektorer
  • Apex Duo: parallell korsjämförelse mellan två oberoende geodetiska beräkningsmotorer

How to process GNSS data online

Step-by-step workflow to process raw GNSS observations into precision coordinates in the cloud.

  1. Upload observation data

    Upload raw receiver logs (UBX, SBF, Trimble, Leica) or standard RINEX 2/3/4 observation files.

  2. Select solution type

    Choose your desired processing engine mode: Static PPP, Kinematic PPP, PPK baseline, or Network Adjustment.

  3. Configure antenna and station metadata

    Specify antenna calibration model and antenna reference point (ARP) height, or let PosFlow extract header metadata.

  4. Run cloud processing and export deliverables

    Execute the automated cloud solution, inspect residual plots and variance metrics, and download high-precision coordinates in your target coordinate reference system.

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 valid time tags or missing header records

Intact observation headers with valid time tags and observation types so the processing engine can synchronize epochs.

Sessions with severe multipath and tracking interruptions below threshold

Adequate carrier phase continuity and satellite elevation coverage to achieve stable ambiguity convergence.

Kinematic trajectory files without antenna height or lever-arm information

Accurate antenna height and 3D offset vectors to translate phase center solutions to ground markers or camera sensor centers.

Common questions

Vad är fördelen med molnbaserad bearbetning jämfört med skrivbordsprogram?

PosFlow hämtar automatiskt exakta satellitbanor, antennkalibreringar och atmosfärsmodeller, vilket besparar ingenjören manuellt sökarbete.
