Mag-upgrade mula sa TEQC patungo sa modernong cloud GNSS quality engine

Wala nang mga kumplikadong command-line parameters. Mag-upload ng mga observation file at makakuha ng kumpletong quality report na may suporta sa multi-GNSS.

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

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.

Bakit kinakailangan ang modernong alternatibo sa TEQC?

Itinigil ng UNAVCO ang pagpapanatili ng TEQC noong 2019. Hindi nito sinusuportahan ang RINEX 4 o mga modernong signal tulad ng Galileo E6 at BeiDou B2b.

Mga bentahe ng PosFlow Crux kaysa sa TEQC

  • Buong suporta para sa RINEX 2.11, 3.0x, at 4.0x
  • Awtomatikong pag-download ng broadcast at precise ephemeris
  • Graphical skyplots at interactive SNR charts sa halip na mga cryptic text file
  • Modernong pagtukoy ng cycle slips sa pamamagitan ng multi-frequency linear combinations

How to replace TEQC with modern multi-GNSS cloud quality control

Migrate legacy TEQC workflows to modern browser-based multi-constellation QC without installing command-line tools.

  1. Import modern RINEX 3 or 4 data

    Upload multi-frequency RINEX observations directly without down-converting to RINEX 2.

  2. Execute multi-constellation analysis

    Run cloud QC across GPS, GLONASS, Galileo, BeiDou, and QZSS simultaneously.

  3. Verify cycle slips and multipath

    Examine normalized cycle slip rates and multipath linear combinations with interactive charts.

  4. Export compliance reports

    Download publication-ready summary reports and share verifiable results with project stakeholders.

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.

Uploading only a navigation/ephemeris file and expecting a quality score from it on its own

The observation file itself. Quality metrics describe what the receiver tracked; ephemeris for the satellite geometry is fetched separately.

A file that has already lost observation types through an earlier, lossy conversion

The original observation log as recorded. A file that has already been through another conversion step is checked as it stands, not restored to what the receiver first wrote.

Epochs out of chronological order, or a session cut short mid-file

A complete, correctly ordered session. Reordered or missing epochs make the composite score describe the damage, not the receiver's tracking.

Common questions

Maaari bang i-batch process ang mga file tulad ng ginagawa sa TEQC scripts?

Oo, nag-aalok ang PosFlow ng REST API at cloud batch processing para sa automation ng mga CORS network.
