Beginning January 1, 1994, (not shown in this report) we are using the ITRF92
site coordinates and the ITRF92 velocity field for sites used in our global
analyses. The official ITRF92 coordinates and velocities were modified
according to the two updates by Zuheir Altamimi; see IGS Mail Messages #421
and #430. Additionally, we now constrain 13 sites as fiducials instead of 8,
which were agreed upon at the IGS Analysis Center Workshop in Ottawa, Canada
(October, 1993).
We separately analyzed days 001 and 002 (Jan 1, 2) using coordinates from both
the new and old terrestrial reference frames (ITRF92 w/13 constrained sites;
ITRF91 w/8 constrained sites). In order to expedite processing, a well-
distributed subset of 25 sites was used for these comparisons. The following
offsets were computed between the two strategies (ITRF92-ITRF91):
Jan 1 Jan 2
------- -------
X-POLE [mas] = -0.82 -0.83
Y-POLE [mas] = -0.21 0.14
ORBITS (3d-rms) [m] = 0.15 0.16
SITE POSITION (3d-rms) [cm] = 2.5 2.6
WARNING: No warnings for GPS week 730.
