****************************************************************************** DORISMail 23-Sep-2003 10:36:26 Message No 0264 ****************************************************************************** Author: Martine Feissel-Vernier Subject: 2003 IDS ANALYSIS CAMPAIGN 2003 IDS ANALYSIS CAMPAIGN IMPACT OF GRACE GRAVITY FIELD MODELS ON IDS PRODUCTS The first gravity field models derived from the GRACE mission were released in late July 2003. This new generation of gravity field models is expected to bring better accuracy and consistency in satellite geodesy applications, particularly for low orbiting satellites, hence for the IDS products. Several DORIS analysts have started to test the use of these models in their computations, and some improvements are announced. Taking the opportunity of this important event, the IDS Analysis Coordinator and the IDS Central Bureau jointly organize an Analysis Campaign on the topic "Impact of GRACE gravity field models on IDS products". Information and Call for Participation are available at http://lareg.ensg.ign.fr/IDS/events/camp_2003.html The results will be discussed at an Analysis Workshop to be held in the first half of 2004. All IDS Analysis Centers are encouraged to participate in this campaign.
