Check, convert, position,
and transform your GNSS data.
From raw observation ingest through quality validation, high-precision solving, and coordinate delivery, PosFlow covers the complete workflow.
Quality check
Crux scores every observation file from 0 to 100 before a single epoch enters the processing pipeline. Catch cycle slips, multipath anomalies, and signal degradation early, before they cost compute time.
Open CruxFormat conversion
Flux is the ingestion and format conversion layer of PosFlow. Accept any major GNSS receiver format, convert to the RINEX version you need, and deliver clean observations to downstream tools.
Open FluxPrecise positioning
The core of PosFlow. Apex delivers precise point positioning, PPK against your own base station, multi-station network adjustment, and Apex Duo, which compares two independent processing engines, - with full antenna models and configurable elevation masks.

Open ApexCoordinate transformation
Axis handles the final step: shifting coordinates between datums, projections, and CRS frames. Transform a single point interactively, or a whole coordinate file in batch.

Traditional GNSS workflows force surveyors to juggle outdated command-line utilities, proprietary Windows tools, and manual ephemeris downloads. PosFlow brings conversion, quality checks, precise positioning and coordinate transformation into one workspace you use from a web browser.
| Capability | Legacy Desktop (TEQC / RTKLIB / Vendor Utilities) | PosFlow Cloud Workspace |
|---|---|---|
| OS & Deployment | Windows-only binaries or OS-specific Linux compilation with Perl wrappers. | ✓Zero installation. Used from a web browser on macOS, Windows, Linux, and tablets. |
| Precise Ephemeris | Manual search and FTP download of orbits/clocks from CDDIS or IGS servers. | ✓Orbit and clock products from IGS, CODE, GFZ and WHU are fetched and matched automatically. |
| Constellation & RINEX | TEQC is unmaintained (stuck on RINEX 2.11 / GPS+GLO); loses modern frequencies. | ✓Native RINEX 2.x, 3.x, and 4.x. Quality checks read GPS, GLO, GAL, BDS and QZSS; precise positioning selects from GPS, GLO, GAL and BDS. |
| Quality Control (QC) | Disparate text outputs requiring manual parsing; no standardized scoring. | ✓Four quality-check modes (Fast, Flash, Full, TEQC) with unified 0-100 composite scoring and anomaly triage. |
| Precise Positioning | Complex local parameter setups, high memory usage, and single-engine risk. | ✓Cloud-native PPP, PPK and network adjustment, with traceable results. Apex Duo compares two independent processing engines on static PPP and static networks. Check each solution in the app for current availability. |
| Sharing & Deliverables | Raw ASCII files and proprietary logs shared via email or thumb drives. | ✓Interactive web dashboards, PDF reports and shared links. |
