#### END HEADER ####

Dear colleagues,

The DORIS antenna at SAL has recently been replaced in order to overcome 
power loss on the 400MHz channel. Given that the equipment replacement 
was not performed by IGN, 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 :
