#### END HEADER ####

Dear colleagues,

At the end of 2014, the DORIS antenna at TERRE ADELIE has been broken in 
two without explanation. Given that the antenna replacement was 
performed by the host agency, high precision control survey could not be 
carried out. It is assumed that the position of the antenna remain 
unchanged after replacement.
Please find below the installation characteristics and the coordinates 
of the new reference point :
