Dear Colleagues,
As agreed by the IGS Analysis Centers, please find below the ITRF93
coordinates at epoch 1995.0 we computed for the 13 stations to be
fixed/constrained.
Brian Murphy from AUSLIG has reported in a message we received on 7 December
1994, that they performed a new local adjustment for Tidbinbilla site on 29
November 1994. This new adjustment called TIDLOCAL produced the following
new tie values:
Point DOMES number
--------- ------------
AU017 50103M108 (Rogue antenna marker)
DSS43 50103S001
DSS45 50103S010
TIDLOCAL adjustment X Y Z Chord
DSS45 - DSS43 40.710 -404.168 -367.147 547.545
DSS45 - AU017 -60.720 -208.617 -62.493 226.083
The local tie used in the ITRF93 adjustment is:
50103S010 50103M108 -60.781 -208.581 -62.538
Using the new local tie values, a readjustment of Tidbinbilla ITRF93
coordinates at epoch 1993.0 was perfomed. These new Tidbinbilla
station coordinates will be appended to the ITRF93.SSC file which can be
obtained by ftp from:

The following coordinates at epoch 1995.0 for the 13 stations take into
account the new local tie at Tidbinbilla site.
On the other hand, in order to be consistent with the series of Earth
orientation parameters produced by the IERS Central Bureau, the ITRF93
velocity field (and not ITRF93N) has been used to map the coordinates from
1993.0 to 1995.0 epoch.
Best regards, Merry Christmas and Happy New Year 1995.
