IVS Analysis Report for VO3138 (20230518-vo3138) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by Sergei Bolotin, NVI, Inc. / NASA Goddard Space Flight Center. Spoolfile source: nuSolve solutions.) Problems: GGAO12M (Gs) No valid fringes found. Antenna not tracking (139-07:37 -- 139-11:00). Band A lost timing (139-05:15 -- 139-11:00). The station was deseleceted from the solution. HOBART12(Hb) Late start (138-18:32). DBBC reboot (139-00:40 -- 139-00:54). Weak D band pcal amplitudes. Very noisy observaitons, wrms of the station is about 300ps, that have large impact on overall session performance. The residuals have the same pattern as phase calibrations of the station. ISHIOKA (Is) New sampler delays. Intermittent weak pcal amplitudes. MACGO12M(Mg) Ran warm (139-07:15 -- 139-08:15). WESTFORD(Wf) Fringes found at clock offset -999933.136 usec. Parameterization comments: Two clock break parameters were added to HOBART12. Other comments: None. ----------------------------------------- Session statistics Observations: 7842 scheduled 7412 correlated (in database) 4913 recoverable (usable) 4555 used Session fit: 40.057 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used GGAO12M 2617 DESELECTED DESELECTED 0.0% HOBART12 1120 941 893 79.7% ISHIOKA 2123 1662 1461 68.8% KOKEE12M 2777 2243 2073 74.6% MACGO12M 2814 2092 1964 69.8% RAEGYEB 1826 1248 1183 64.8% WESTFORD 2407 1640 1536 63.8% --------------- --------- ----------- --------- ------ Station Total** 7842 4913 4555 58.1% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
