Subject: ITRF92 coordinates

Subject: ITRF92 coordinates


Dear colleagues,

It was agreed with the Analysis Center Coordinator to compile the ITRF92
coordinates of the 13 stations to be fixed or constrained tightly by the
Analysis Centers. In order to do that we first performed some verifications
and consistency tests between the ITRF91 and ITRF92 coordinate and velocity
sets. As result of these tests, we have to point out the following remarks:

1. The ITRF92 station coordinates have been adjusted by combination of VLBI,
LLR, SLR and GPS solutions at epoch 1988.0. The GPS solutions included in
this adjustment were derived from IGS'92 observations. While all the
VLBI, LLR and SLR station coordinates have been provided by the
corresponding analysis centers at epoch 1988.0, the GPS station
coordinates have been provided by IGS analysis centers at the central
epoch of observations (1992.6). These GPS stations coordinates were
mapped at epoch 1988.0 using the ITRF91 velocity field.

2. It appears that SOME of the ITRF91 sites have their VERTICAL velocities
probably too large to represent real geodetic motion. As far as the IGS
is concerned, only two GPS sites are in this case. These two sites are
PENTICTON and ZIMMERWALD with vertical velocities 24.3 and 8.1 mm/y
respectively. Meanwhile the ITRF92 vertical velocities for these two
sites are more "realistic" ; 0.7 and -2.1 mm/y respectively.

3. Concerning the VLBI and SLR sites (which are not GPS sites) whose
ITRF92 velocities are "largely" different from ITRF91, they did not
disturb the ITRF92 coordinate combination. This is due to the fact that
station coordinates were originally provided by the VLBI and SLR analysis
centers at epoch 1988.0.

4. The ITRF92 site velocities seem to be more realistic wrt ITRF91 with the
exception of YELLOWKNIFE whose VERTICAL velocity is probably too large;
19.4 mm/y which is certainly due to a poor VLBI estimate.

5. The ITRF92 coordinates at epoch 1988.0 of PENTICTON and ZIMMERWALD were
corrected by the difference of their velocities between ITRF91 and ITRF92
(over 4.6 years = 1992.6 - 1988.0).

6. Concerning YELLOWKNIFE, we recommend to use the NNR-NUVEL1 velocity
instead of ITRF92 one.

7. The file ITRF92.SSC was updated by the 3 above corrections (position of
PENTICTON and ZIMMERWALD and velocity of YELLOWKNIFE). This file can be
downloaded by ftp from

URANUS.IGN.FR (192.33.147.79)

login: ITRF
password: IERSPUB
file: ITRF92.SSC

8. The velocity differences for PENTICTON and YELLOWKNIFE explain the
large discrepancies between the previous ITRF92 coordinates and GPS
estimates pointed out by J. Kouba in his message #417. This should
be also the case for ZIMMERWALD.

Please find below the ITRF92 coordinates AT EPOCH 1994.0 of the 13 stations
to be fixed or constrained tightly by the Analysis Centers. We also provide
the ITRF92 coordinates (also at epoch 1994.0) for the other remaining
stations.

The antenna heights as well as the local ties between SLR/VLBI and GPS
markers were updated recently by W. Gurtner and Z. Altamimi. The file
containing these values can be downloaded by ftp from IGS Central Bureau:

Remark: The above 13 station coordinates refer to the GPS MONUMENTS with
the exception of MADRID and GOLDSTONE_PEQ whose coordinates refer
to the botom of the antennas (ARP).
The coordinates of TIDBINBILLA (named previously CANBERRA)
were originally referred to the ARP. Here they are reduced to the
GPS monument using the antenna height given in the file localtie.tab.
