This campaign was initiated in April of last year mainly for improving the quality of Earth orientation oarameter (EOP) estimates obtained from SLR observations. At the recent AWG meeting in Nice, analyses to date showed that the addition of the ETALON data improved the quality of the EOP results only slightly (~5%), but further improvement may be reached through further analysis. The AWG requested the continuation of the campaign to utilize the data for other ILRS products such as absolute scale, station characterization, temporal variations in the gravity field. The results from the ETALON campaign will be reported at the ILRS meeting in October.
