Global VLBI solution 2002c


Geographical Survey Institute global solution 2002c used all available dual band VLBI observations (except VLBA Calibrator Surevy) at 8.4GHz and 2.2 GHz from 1980.04.11 till 2002.11.11, 3485 diurnal sessions, 3,580,139 measurements of group delays.
Single combined least square solution was done.

Source positions

Positions of 552 sources were estimated as global parameters. A source which participated in 2 or more sessions and had 40 or more good observations is in the list of global sources. A source which participated in 1 session and had 25 or more good observations is in the list of global sources also. Positions of other 181 sources were estimated for each session independently.

Comparison of EOP series

Comparison with IERS C04 series shows random noise with slight linear trend with scatter comparable with the accuracy of VLBI EOP series, except UT1 where the noise of IERS C04 series is dominating.
