IVS Analysis Report for AOV024 ($18JUN19XA) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) This is a remake of the AOV024 session with data from SYOWA added in. Problems: Source 1600+43B was renamed to 1600+43A at GSFC. During the course of generating ICRF3, it was found that observations of these two sources yielded the same positions, so all occurances of 1600+43B were changed to 1600+43A. This is a weak source and it was not detected in this session. Difficult ambiguity resolution because the single-band delays are not usable. The X-band ambiguities at KASHIM11 were only 3.3 nsec and could not be resolved. Parameterization comments: Currently there are some problems in generating EOP and Sinex solutions with this database as well as with the AOV020/18FEB27XA session. We are investigating and will not submit the databases until the problems are resolved. Other comments: None. ----------------------------------------- Session Statistics Observations: 2704 scheduled 2374 correlated (in database) 2369 recoverable (usable) 1794 used Session fit: 97.671 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART26 869 808 686 78.9% KASHIM11 676 512 NOT USED 0.0% KATH12M 911 860 715 78.5% SEJONG 747 660 468 62.7% SYOWA 637 503 477 74.9% WARK12M 712 579 540 75.8% YARRA12M 856 816 702 82.0% --------------- --------- ----------- --------- ------ Station Total** 2704 2369 1794 66.3% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
