#### END HEADER ####

Dear colleagues,

A new DORIS station has recently been installed in the Mariana Islands, 
at Mangilao in the premises of the University of Guam. This station is 
used for scientific purposes, as IDS station (off the orbitography 
network for now).

Transmissions started on April 12, 2018.

Coordinates and velocities derived from the connection to the nearby IGS 
station "GUUG".

Please find below the installation characteristics and the coordinates 
of the new reference point :

Concerned site:
#### BEGIN SITE ####
Site name         : MANGILAO     ####
Site DOMES number : 82301     ####
#### END SITE ####

Characteristics of the new point:
#### BEGIN STATION ####
