Agenda

Opening – Agenda review and adjustment & announcements  
Old topics:  
 
  • Benchmark project: status
    • GA
    • GRGS
    • UoN
  • Operational product "positioning + earth orientation"
    • ITRF2005 & ITRF200X: ILRS 1983-1992 reports on analysis progress
      • ASI
      • BKG
      • DGFI
      • GFZ
      • JCET
      • NSGF
    • operational product: ILRS-A/B technique issues, quality/refinement of products (e.g. weekly geocenter)
      • Generation of a SLR-only TRF ala IGS00, etc.
      • Adoption of an ITRF2000 replacement timetable (ITRF2005SLR?)
    • new products (e.g. daily EOP ala NEOS)
  • System bias studies (present and future):
    • Stanford ET status report (Appleby & Gibbs)
    • CoM corrections for all targets, sites and time periods/configurations
    • Core site bias characterization in view of ILRS’ mm-SLR goal
  • Quality assessment of new SLR systems/sites (H. Müller)
  • Station performance card (ASI CC & DGFI CC)
  • Precise orbital product project (SP3c)
    • Status report (ECP & Müller and CC reps)
  • Project "harmonization"
    • Status report (Mareyen)
 
NEW topics:  
 
  • GGOS and ILRS, establishing a closer tie with GGOS and maintaining a “live” link to GGOS, providing input for the studies and support documents that GGOS requires
  • Independent validation of SLR height variations and bias estimates with a routine AG survey of the core sites over time (1 to 4 times per year - baseline, once a month - goal)
  • Report of the new WG on the evaluation/validation effort for site-ties between SLR and other techniques (GB & CL)
  • Generation of “clean” observational data set with known biases applied? (for use by POD groups)
  
Miscellanea:  
 
  • SLR tracking network (status, weekend effect)
  • consistency of QC reports (ILRS CB)
  • documentation of analysis (ECP & CL)
  • special issue Journal of Geodesy (Noomen)
  • other ???
  
Next meeting(s):  
 
  • 2-day meeting at Perugia (IUGG/IAG, July) ?
  • 1-day meeting at Grasse Tech. Workshop (September)?
  • N-day IAG Services’ workshop prior to Fall AGU (San Francisco, December ‘07)
