Subject: No 0934 : Network/ new point MARION ISLAND
#### END HEADER ####

Dear colleagues,

The DORIS antenna at MARION ISLAND has recently been replaced in order 
to overcome disruption and power loss on the 400MHz channel. Given that 
the equipment replacement was performed by the host agency, no high 
precision control survey was 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 :
