Subject: Estimated pole offset ITRF92-ITRF93

Since 01/01/95 we have started to use the ITRF93 coordinates
and velocities as has been recommended. Please, notice
that item 4 of our report of Wk 0782 is wrong. We are using
ITRF93 at 1995.0.

Week 0782 has been recomputed using ITRF92 to estimate the
average pole offset. The results are the following:

                          Xp offset  sigma   Yp offset  sigma
                            (mas)    (mas)    (mas)    (mas)
ITRF92-ITRF93  EOP          0.502    0.15     1.789     0.09
ITRF92-ITRF93  orbits       0.491    0.13     1.810     0.09


Best regards.
