INTERNATIONAL EARTH ROTATION SERVICE
EARTH ORIENTATION PARAMETERS
Section 6 of the Bulletin B 102
6 - SUMMARY OF CONTRIBUTED EARTH ORIENTATION PARAMETERS SERIES
This section gives the average precision of the individual series
contributing to the combination and their average agreement with it.
Since June 30, GPS solutions are referred to ITRF94. In order to avoid
discontinuities in the current combined solutions, all series have been
referred back to ITRF93 system. Analyses of the next Bulletin B103 will
take into account series in the ITRF94 system.
For complete list of data, see Bulletin B in section 7.
Units : 0.001" for x,y , 0.0001s for UT1, 0.001" for dPsi, dEpsi.
