IVS Analysis Report for R4882 ($19FEB21XE) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by Christopher Dieck, US Naval Observatory. Spoolfile source: interactive nuSolve analysis.) Problems: FORTLEZA - Had power failures 053-06:56 to 8:11 and from 053-18:09 to 18:30. MATERA - Had patches of subambiguities on the S-band, which were deselected. NYALES20 - Started late at 053-07:41 due to high winds. Parameterization comments: - The MATERA cable calibration degraded the solution and was deselected. - Clock breaks were added as follows: MATERA 19/02/22 13:34 Other comments: - Due to dropped channels, the S-band ambiguity spacing is 50 ns on all FORTLEZA and MATERA baselines.
