Analysis Working Group Report ILRS General Assembly Meeting Poznań, Poland, Oct. 16, 2008 Erricos C. Pavlis Analysis Coordinator

AWG Projects Eight AC: ASI (AC & CC), BKG, DGFI (AC & CC), GA, GFZ, GRGS, JCET, and NSGF Candidate AC/AAC undergoing benchmarks: AIUB, ESOC and NCL Operational products (weekly & daily) are delivered routinely on time Re-analysis for 1993 to present: ASIv12June 08 GAv11August 08 GFZv10January 08 GRGSv11June 08 Historical data re-analysis 1983 to 1992: ASIv12September 08 GFZv10September 08 All ACs to complete submissions by end of 2008

AWG New Projects Pilot Projects currently in progress: – Orbit products (SP3C files) -- FIVE ACs in testing (ASI, BKG, DGFI, GA, JCET) – Daily solutions of 7-day arcs for 1 d EOP for NEOS (FIVE ACs + DGFI soon!) New Potential projects: – CRD data format submission station qualification process (ASI, GFZ, GRGS, JCET) – Testing the application of atmospheric effects in ILRS products – Generation of a “low degree ~2 harmonics” series (for CPP/GGOS) – 3-4 ACs to study the possibility of a new definition of NP generation procedure – Use of Starlette and Ajisai initially for EOP and eventually for TRF products with improved modeling (e.g. atmospheric effects) – Near real-time analysis of SLR data for “station health”/bias Rpts.

AWG Meetings, Past/Future The AWG met twice so far in 2008: – EGU 2008, Vienna, Austria – 16th International Laser Workshop, Pozna ń, Poland Other meetings in 2008: – Not likely Next meeting: EGU 2009, likely dates April (24), 25

AWG Documentation All ACs and CCs have submitted online documentation (required by IAG/IERS) describing the models and standards used in their routine analysis, some AACs ( need to remind them often! ) A LR-dedicated special issue of the Journal of Geodesy to be compiled in the coming year for better and wider documentation of ILRS (ground segment, space segment, data analysis and interpretation)
