Precise point positioning in the cloud
Upload static or kinematic RINEX observation files and obtain survey-grade coordinates with DATAPOOL-first precise orbits, clocks, and ionospheric corrections.
Rigorous geodetic engines, cloud simplicity
Apex brings scientific-grade dual positioning engines into an automated cloud pipeline. No complex script setup, no manual product downloading, and no proprietary lock-in.
Capabilities & features
- Static PPP for geodetic control networks, benchmarks, and CORS stations
- Kinematic PPP and PPK trajectory solving for aerial surveying and hydrography
- Multi-constellation support: GPS, GLONASS, Galileo, BeiDou, QZSS
- Automated fetch of final, rapid, and ultra-rapid IGS precise orbits and clocks
- Complete antenna phase center modeling (IGS antenna calibrations) and troposphere estimation
- Detailed solution reports: coordinates (ITRF/WGS84), covariance matrix, formal uncertainties, and residual plots
Traceable results for engineers and researchers
Every Apex solution outputs formal mathematical variances, processing logs, and coordinate estimates, ensuring full reproducibility for peer-reviewed research and regulatory engineering deliverables.
Common questions
How long does a static PPP session need to be?
There is no universal session length or guaranteed accuracy. Convergence depends on phase continuity, satellite geometry, precise products, antenna metadata and the processing strategy. Inspect the solution time series and residuals, and verify coordinates against independent control.
Which precise products does POSFLOW use?
POSFLOW automatically pulls high-grade precise orbit and clock products from IGS (International GNSS Service), CODE, GFZ, and Wuhan University Analysis Centers based on observation epoch.
