IVS Analysis Report for R4785 ($17MAR30XE) 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: NYALES20 - Did not participate. WETTZELL - The correlator added a clock break at 090-1119, and a commensurate clock break was added in the analysis. MATERA - Cable calibration was suspect, and degraded the solution when applied, so it was not applied. MATERA:ZELENCHK was deselected due to its small S-band ambiguity spacing. Parameterization comments: Since WETTZELL had a clock break, HART15M:MATERA was used as the clock reference and WETTZELL was the position reference. The URUMQI clock moved around a lot. To smooth it out, clock breaks were added at URUMQI 17/03/30 20:14 -29.410 ns URUMQI 17/03/31 00:04 13.598 ns URUMQI 17/03/31 16:50 20.032 ns Also, a baseline clock offset was added to the MATERA:URUMQI baseline. Other comments: This is the analysis of the final database release. Due to dropped channels, all baselines of ZELENCHK have 50ns S-band ambiguity spacings, except for HOBART12:ZELENCHK which has an 8.3ns S-band ambiguity spacing and MATERA:ZELENCHK, with only one shared S-band channel, which has a 0.4ns S-band ambiguity spacing. ----------------------------------------- Session Statistics Observations: 5698 scheduled 4375 correlated (in database) 3922 recoverable (usable) 3598 used Session fit: 34.547 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HART15M 1051 794 775 73.7% HOBART12 672 575 563 83.8% KATH12M 771 674 658 85.3% MATERA 1378 1042 785 57.0% NYALES20 1198 NOT CORR NOT CORR 0.0% SVETLOE 1424 1109 1095 76.9% URUMQI 1240 709 675 54.4% WETTZELL 1421 1089 1068 75.2% YARRA12M 809 705 689 85.2% ZELENCHK 1432 1147 888 62.0% --------------- --------- ----------- --------- ------ Station Total** 5698 3922 3598 63.1% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
