Subject: Network/ ERRATUM - coordinates update GREENBELT

DORISMail version 1.1
Subject: No 0831 : Network/ coordinates update GREENBELT
#### END HEADER ####

Dear colleagues,

In DORISMail No 825, I gave coordinates (ITRF2008, 2005.0) for the new
antenna at GREENBELT (GRFB) derived from a geodetic connection to the DORIS
mark. 

Due to database update issues, Y value was erroneous.

I apologize for any inconvenience this mistake may have caused. 

A new sitelog will be soon available on the IDS website.

Please find below the correct coordinates of GRFB:

Concerned site:
#### BEGIN SITE ####
Site name         : GREENBELT ####
Site DOMES number : 40451 ####
#### END SITE ####

Characteristics of the new point:
#### BEGIN STATION ####
Four character ID           : GRFB     ####
Station DOMES number        : 40451S178     ####
#### END STATION ####

The coordinates of the DORIS antenna reference point are:
#### BEGIN COORDINATES ####
Solution : ITRF2008 ####
Note about the coordinates : tie to GREB     ####
Epoch    : 2005.0     ####
Unit     : metre     ####
X        : 1130711.237     ####
Y        : -4831392.165     ####
Z        : 3994061.383     ####
Sig X    : 0.002     ####
Sig Y    : 0.001     ####
Sig Z    : 0.001     ####
#### END COORDINATES ####

The ITRF velocities for the site are:
#### BEGIN VELOCITIES ####
Note about the velocities :     ####
Unit     : metre / year     ####
VX       : -0.0146     ####
VY       : -0.0027     ####
VZ       : 0.0021     ####
Sig VX   : .0005     ####
Sig VY   : .0004     ####
Sig VZ   : .0003     ####
#### END VELOCITIES ####
