High-Accuracy GNSS Orbit and Clock Predictions for PPP Workflows


  • 100% data availability — no missing epochs, no reliance on continuous connectivity


  • Instant positioning capability — no delay in time-to-first-fix (TTFF)



  • Flexible temporal resolution — configurable from 1s to 30s (24-hour horizon standard)


  • Precomputed SP3 products — available prior to first prediction epoch 


High-accuracy GNSS orbit and clock predictions for PPP workflows.

This approach reduces reliance on continuous real-time correction streams by providing precomputed SP3 products with full data availability and no connectivity requirements.

Designed for applications where consistency, availability, and deployment simplicity are critical.

Analysis

*RTS vs PORG analysis shown for a typical GPS week. Higher accuracies are achievable with a single midday update.




Future Development


We are currently exploring the extension of this approach to non-terrestrial positioning systems, including the development of predicted orbit and clock products for lunar navigation


This includes the generation of SP3-format ephemerides in a selenographic reference frame, supporting future lunar GNSS concepts and positioning frameworks.


These efforts are aligned with emerging lunar navigation architectures and aim to provide similar advantages in availability, independence from continuous correction streams, and flexible deployment.
