Fagard" Subject: Antenna accidental displacement at Rikitea (RIKB) Dear Colleagues, A sudden shift of the DORIS antenna at Rikitea (RIKB) has been detected by the IGN analysis centre, and confirmed by SSALTO. The offset is about 5 cm horizontally, and dates back to June 4. The reason for this move was investigated with the host agency: it was caused by a car bump on the lower section of the lattice tower which supports the antenna. The beacon is transmitting normally since then, and the new antenna position seems stable. We plan to replace the damaged tower, and survey the antenna excentricity.
