Dear Colleagues,
The corroded supporting plate of the DORIS antenna at Amsterdam Island (AMSB) was changed on March 28, with a new plate made of high quality stainless steel (AISI 316 L).

The antenna excentricity was measured with respect to the initial position:
- for the 400 MHz phase center (antenna reference point): 2 mm towards North, 28 mm towards West;
- for the 2 GHz phase center: 4 mm towards North, 64 mm towards West.
A new Starec antenna was installed. Its new acronym is AMTB, and the DOMES number for the new antenna reference point is 91401S003.

Best regards,

Herve Fagard
