Fagard" Subject: Antenna drift at Amsterdam Dear Colleagues, We have been informed that because of a considerable corrosion of its aluminum supporting plate, the DORIS antenna at Amsterdam Island is out of vertical by a few centimeters. Therefore positionning and horizontal velocity results should be considered biased over the last few months. The exact excentricity will be measured, and the plate replaced, when a surveyor can travel to this remote location, which is planned for next April.
