IVS Analysis Report for R1849 ($18JUL02XA) 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, Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: AGGO switched back and forth between different field system versions. This caused clock jumps of -2 seconds (~21:00) and +2 seconds (~06:45). Numerous other problems. No data 4:13-6:47. Small clock break at SEJONG at ~05:20. HART15M shows large clock variations, requiring a large clock constraint, used 10.D-14. KATH12M no data 23:51-05:26, reason unknown. YARRA12M missed first ~4 hours, reason unknown. Parameterization comments: None. Other comments: This is the reprocessed version with FORTLEZA included. First data to AGGO (Argentina) station. Looks okay except for the two large clock breaks. WETTZ13N-WETTZELL baseline deselected, no usable data. ----------------------------------------- Session Statistics Observations: 3027 scheduled ? correlated (in database) 2505 recoverable (usable) 2313 used Session fit: 41.113 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used AGGO 427 309 308 72.1% FORTLEZA 465 424 416 89.5% HART15M 686 562 562 81.9% KATH12M 694 465 454 65.4% NYALES20 803 738 727 90.5% SEJONG 717 579 568 79.2% WETTZ13N 817 746 579 70.9% WETTZELL 813 747 580 71.3% YARRA12M 632 440 432 68.4% --------------- --------- ----------- --------- ------ Station Total** 3027 2505 2313 76.4% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
