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.
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.
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.
The core of PosFlow. Apex delivers precise point positioning, PPK against your own base station, multi-station network adjustment, and dual-engine cross-check — with full antenna models and configurable elevation masks.
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.
Why Cloud-Native Beats Legacy Desktop Toolchains
Traditional GNSS workflows force surveyors to juggle outdated command-line utilities, proprietary Windows tools, and manual ephemeris downloads. PosFlow unifies the entire geodetic pipeline into one browser workspace.
| 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. Runs in any browser on macOS, Windows, Linux, and tablets. |
| Precise Ephemeris | Manual search and FTP download of orbits/clocks from CDDIS or IGS servers. | ✓Automatic sub-second orbit and clock pairing from IGS, CODE, GFZ, and WHU. |
| Constellation & RINEX | TEQC is unmaintained (stuck on RINEX 2.11 / GPS+GLO); loses modern frequencies. | ✓Native RINEX 2.x, 3.x, and 4.x across all 5 constellations (GPS, GLO, GAL, BDS, QZSS). |
| Quality Control (QC) | Disparate text outputs requiring manual parsing; no standardized scoring. | ✓4 parallel QC engines 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 with dual-engine cross-verification and traceable, centimeter-level deliverables. |
| Sharing & Deliverables | Raw ASCII files and proprietary logs shared via email or thumb drives. | ✓Interactive web dashboards, publication-grade PDF reports, and secure shared links. |
