2004
December 2004 -- The twelfth AWG meeting (PDF) was held December 13, from 09:00 to 12:00, during the Fall AGU meeting in San Francisco, CA.
June 2004 -- The eleventh AWG meeting (PDF) was held June 5, from 14:00 to 17:00, prior to the 14th International Workshop on Laser Ranging in San Fernando, Spain.
April 2004 -- The tenth AWG meeting (PDF) was held April 22-23, prior to the EGU meeting in Nice, France.
2003
Koetzting 2003 -- The ninth AWG meeting (HTML/Word) was held October 25-26, prior to the ILRS Technical Workshop in Koetzting Germany. Progress on the ILRS response to the Call for Participation (CfP) for generation of ILRS products (EOP and station positions) was discussed.
April 2003 -- The eighth AWG meeting was held April 3-4, prior to the joint EGS/AGU meeting in Nice, France. The Call for Participation (CfP) for generation of ILRS products (EOP and station positions) was discussed. Results of the QC Harmonization and Software Benchmarking were also presented and discussed.
2002
October 2002 -- The seventh AWG meeting was held prior to the Thirteenth Internation Workshop on Laser Ranging at HTSI in Lanham, MD, October 3-4, 2002. A Call for Participation (CfP) for generation of ILRS products (daily X/Y pole, LOD for input to IERS Bulletin A) and daily X/Y pole, LOD, and coordinates (28-day arcs) was discussed and will be issued in the near future.
April 2002 - The sixth AWG was held in Nice, France. POS+EOP solutions and combinations were presented and discussed. It was agreed to combine software benchmarking and orbits into a single project named "Software Benchmark and Orbits". Development of a Request for Proposal (RFP) for the combination of POS+EOP solutions were discussed. There was a request to extend the ETALON campaign until October, 2002.
2001
September 2001 - The fifth AWG workshop was held in Toulouse, France. POS+EOP solutions and combinations were presented and discussed. There was a request to extend the ETALON campaign until April, 2002.
April 2001 - This was the beginning of the ETALON campaigns.
March 2001 - The fourth AWG workshop was held in Nice, France. POS+EOP solutions and combinations were presented and discussed. The pilot project data set has been expanded to include Etalon-1 and -2, and the EOP's parameters have been extended to include the EOPs time derivatives (phase V). Also, for POS+EOP, the initial site positions were changed from ITRF 1997 to ITRF 2000.
2000
November 2000 - The third AWG workshop was held in Matera, Italy. POS+EOP solutions and combinations were presented and discussed. It was agreed to expand the pilot project by using one year of data and to generate a time series (i.e. every 4 weeks) of coordinates (phase IV).
May 2000 - The second AWG workshop was held in Deflt, Netherlands. POS+EOP solutions and combinations and harmonization of QC results were presented and discussed. It was agreed to modify the POS+EOP pilot project by the addition of LAGEOS-2 data to the dataset (phase III).
April 2000 - At the EGS XXV General Assembly in Nice, two presentations were given. The first presentation was on SLR orbits, which will be published in Survey in Geophysics, and the second presentation was on combination of SLR coordinates.
January 2000 - The first AWG workshop was held in Franfurt, Germany. Results of the pilot projects were presented and discussed. It was agreed to combine the POS and EOP pilot projects into a single project (phase II) and to establish two new pilot projects (Software Benchmarking and Orbits).
1999
December 1999 - At the 1999 Fall AGU Meeting in San Francisco, a presentation was given on the combination of earth orientation parameters from SLR and LLR, which will be published in a special issue of the Journal of Geodesy.
September 1999 - The first AWG meeting was held September 1999 in Florence, Italy. AWG membership was finalized. Three pilot projects were initiated. These 3 projects were:
- Harmonization of LAGEOS Quality Control (QC) results
- Computation of station POSitions (POS)
- Computation of Earth Orientation Parameters (EOP)
The AWG adopted the SINEX format for exchange of station positions and earth orientation parameters (see the required ILRS elements of the SINEX format). It was agreed not to prescribe full analysis standards, but rather recommend a standard (IERS 1996 Conventions, postscript and .pdf).
ILRS E-mail exploders were established for the Analysis Working Group (ilrsawg@ilrs.gsfc.nasa.gov), the Analysis Centers (ilrsac@ilrs.gsfc.nasa.gov) and the Associate Analysis Centers (ilrsaac@ilrs.gsfc.nasa.gov).
