USNO Analysis Report for R1815 ($17OCT23XA) 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 Nicole Geiger, United States Naval Observatory. Spoolfile source: opa solution.) Problems: HART15M had a large clock variability, which caused the constraint to be increased. MATERA had sub-ambiguities at S-band. SEJONG had sub-ambiguities at S-band. YARRA12M had two clock breaks at 1:44:21 (1.0 nsec) and 11:08:34 (-0,75 nsec). Parameterization comments: None. Other comments: None. ----------------------------------------- Session Statistics Observations: 6327 scheduled 6142 correlated (in database) 5337 recoverable (usable) 4918 used Session fit: 40.995 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used FORTLEZA 654 496 490 74.9% HART15M 1165 1048 997 85.6% ISHIOKA 1488 1388 1329 89.3% KATH12M 1344 1234 1209 90.0% KOKEE 1075 889 816 75.9% MATERA 1273 944 713 56.0% SEJONG 1149 984 767 66.8% WARK12M 1010 879 855 84.7% WETTZ13N 1224 890 817 66.7% WETTZELL 1035 792 736 71.1% YARRA12M 1237 1130 1107 89.5% --------------- --------- ----------- --------- ------ Station Total** 6327 5337 4918 77.7% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
