High-precision PPK processing without the desktop software
Upload overlapping rover and base RINEX observations for kinematic post-processing. Check base coordinates, antenna information and trajectory quality before using the output for mapping or surveying.
Why PPK over RTK?
PPK processes recorded rover and reference observations after a mission, without requiring a live correction link in the field. Signal obstruction and phase interruptions can still prevent reliable ambiguity resolution. Preserve overlapping base data and inspect the trajectory and quality report.
Features for UAV and Survey Professionals
- Process dual-frequency kinematic baselines with your own local base station
- Automated antenna phase center variation (PCV) application via absolute IGS calibrations
- Automatic matching and retrieval of precise orbits and clock corrections
- Multi-constellation solving (GPS, GLONASS, Galileo, BeiDou)
- Detailed timestamped trajectory export for image geotagging and point cloud colorization
Common questions
What formats are supported for rover data?
You can upload standard RINEX observation files. If your drone records in raw binary (like u-blox UBX or Septentrio SBF), you can use the integrated Flux converter to transform them into RINEX directly in the workspace.
Do I need to manually download precise ephemeris?
No. PosFlow Apex automatically pairs the observation epoch with the best available IGS, CODE, or GFZ precise orbits and clocks.
