NASA Analysis Report for R41116 (20230817-r41116) This report is a contributed analysis report that does not correspond to the database maintained by the IVS Data Centers for this session. (Analyzed by Karen Baver, NVI, Inc. / NASA Goddard Space Flight Center. Spoolfile source: nuSolve solutions.) Problems: HOBART12(Hb) No data received yet. SVETLOE (Sv) Dropped for intensive 2023-230-065207 -- 2023-230-075914. ZELENCHK(Zc) Dropped for antenna problems 2023-230-0625 -- 2023-230-0647. Dropped for intensive 2023-230-0652 -- 2023-230-0803. Dropped for antenna problems 2023-230-1014 -- 2023-230-1054. KOKEE had some apparent clock breaks that David Gordon (USNO) identified as actually coming from phase cal problems. The phase cal problems were handled by setting three clock breaks as described in the parameterization section of this report. Several SVETLOE baselines had S-band sub-ambiguities near 30 ns or -30 ns. Parameterization comments: Three KOKEE clock breaks were estimated to handle phase cal problems: 2023/08/18 00:00:00 2023/08/18 15:16:00 2023/08/18 16:52:00 Several baseline clock offsets were estimated: FORTLEZA:NYALE13N KATH12M:KOKEE KATH12M:URUMQI KOKEE:NYALE13N NYALE13N:SVETLOE NYALE13N:URUMQI NYALE13N:ZELENCHK Other comments: FORTLEZA Dropped channel due to low phase amplitude S03UR KATH12M Applied manual phase calibration KOKEE Dropped channel due to low phase amplitude S04UR NYALE13N Applied manual phase calibration URUMQI Applied manual phase calibration ----------------------------------------- Session statistics Observations: 4649 scheduled 3957 correlated (in database) 3730 recoverable (usable) 3095 used Session fit: 33.202 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 520 431 399 76.7% HOBART12 542 NOT CORR NOT CORR 0.0% KATH12M 715 311 271 37.9% KOKEE 1038 867 717 69.1% NYALE13N 1263 1132 987 78.1% SVETLOE 1314 1207 730 55.6% URUMQI 1328 1217 1057 79.6% WETTZELL 1252 1151 1010 80.7% ZELENCHK 1326 1144 1019 76.8% --------------- --------- ----------- --------- ------ Station Total** 4649 3730 3095 66.6% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
