v1.3.0

This release brings performance gains and several features to pppx. Besides, the PPPx Web Viewer is now live — an interactive tool for visualizing .pos and .stat files right in your browser. It also supports online RINEX-OBS processing (PPP mode only), so you can try pppx without installing anything.

Bug fixes

1. The solution status is written as 1/2 (fixed/float) in the .stat file for EKF-based PPP-AR.

Performance improvements

1. Runtime for EKF-based PPP has been roughly halved. Other processing modes also see notable speedups.
2. Removed limit on the number of epochs for FGO.
3. Added inter-epoch position constraints for FGO-based kinematic RTK and PPP.
4. Added support for base observations at a lower sampling rate for RTK (maxage: 3 s, not configurable).
5. Added support for CODE rapid products in scripts/pppx.sh.
6. Refined ambiguity resolution for EKF-based RTK and PPP.
7. Improved the scripts/plot_ppppos.py script .

Others

1. Residuals are no longer written to the .log file (log level moved from info to debug)
2. Processing progress is no longer printed to stdout
3. ZTD ($TROP) is now written to the .stat file
