GSI VLBI solution int01

Geographical Survey Institute solution int01 used 1.5 hour sessions of dual band VLBI observations at 8.4GHz and 2.2 GHz from 1997.01.02 till 2002.11.11 carried out under IVS Intensive program. UT1 angles were determined for each session.

Assessment of accuracy of EOP series

Comparison of UT1 angles determined in 347 IVS Intensive sessions which ran simulataneously with 24 hour VLBI sessions gives us a measure of accuracy of the UT1 estimates. Plot of the differences in UT1 angles determined in 1.5 hour IVS Intensive sessions with respect to 24 hour VLBI sessions.
