IGS Reprocessing at ESOC Features of New GNSS software at ESOC, Napeos: Very fast! 30 minutes for a full final solution from scratch using 100 stations 60 minutes when using 150 stations Product quality excellent (see our posters) Ideally suited for IGS reprocessing But also for IGS real time! Reprocessing is the ideal tool for testing new models Future improvements will come from small model changes which need significant amounts of days (if not months) to be reanalysed. Being able to do that fast and efficient is key for all future progress! ESOC wants to play a significant role in the IGS reprocessing

Current Status of Reprocessing Reprocessed 2007 four times since November 2007 First time as software test for IGS operations Second and third time for IGS reprocessing and Albedo study Once without Earth Albedo and Infra-red radiation modelling (OFF) Once with Earth Albedo and Infra-red radiation modelling (ON, ES1) Fourth time after resolving issue with the CMC correction (see poster) Results have been analysed in some details Orbit overlaps, orbit comparisons, ERP comparisons SLR validations Outstanding checks are: Clock comparisons Coordinate comparisons After completion of the validation the full reprocessing will start!

SLR Validation of ESOC Reprocessed Orbits

Comparison of ESOC Reprocessed ERP Estimates

SLR Residuals (As function of Satellite Latitude and Elevation of the Sun above the orbital plane)

Periodic Signal in Orbit Overlap!

ESOC ready to reprocess all IGS data since 1994 Conclusions ESOC Reprocessed solutions have very high quality! Completely independent 24 hour solutions No smoothing and no day boundary constraints! Small issue with CMC correction detected and fixed Corrected reprocessed series available Several comparisons show 14-day periods, e.g., Orbit Z-rotations, X-, Y-pole and LOD time series, orbit overlaps Most significant effect found in overlap of Right-Ascension of the Ascending Node 14-day period in RAAN overlap dominating the overlap statistics Explanation missing (see also our poster) IERS Sub-daily Polar Motion model too simple? SLR validation of the orbits confirms the high quality Difference between SLR observations and GPS orbits remains Earth Albedo and Infra-red radiation may give the explanation However, the Napeos model is too simple ESOC ready to reprocess all IGS data since 1994
