IVS Analysis Report for APSG46 ($20APR07XA) This report is the official IVS analysis report that corresponds to the database maintained by the IVS Data Centers for this session. (Analyzed by David Gordon, NASA Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Session reanalyzed due to a mod in nuSolve and resubmitted to IVS. Problems: Unlocked BBC's at KUNMING, no signal in channels S2, S6, X2, X3, X4, X6. Missing channels caused X-band subambiguities. Channel S1 was deleted due to low amplitudes causing G codes. KUNMING also has a clock break at ~08:32. The HOBART26-KUNMING baseline has a very large baseline clock offset. The X/S residuals show a bi-modal pattern with lobes separated by ~.5 nsec. The smaller lobe was manually edited out. YARRA12M's clock is unstable with many small breaks. Eight breaks were used: 19:22, 22:42, 23:15, 23:48, 10:35, 11:00, 12:48 and 17:02. HOBART26 missed most of the first 8 hours. The log has a comment about servicing the receiver focus platform. KOGANEI has gaps of ~1 hr and ~2 hrs with only non-detections. The log has many 'ONSOURCE status is SLEWING!' messages. Parameterization comments: None. Other comments: This is a refringed version. The original version had many X-band subambiguities on KUNMING baselines. ----------------------------------------- Session Statistics Observations: 6074 scheduled 5531 correlated (in database) 4100 recoverable (usable) 3757 used Session fit: 40.670 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART26 1446 750 704 48.7% ISHIOKA 2028 1607 1514 74.7% KOGANEI 1946 732 697 35.8% KOKEE 1529 1222 1158 75.7% KUNMING 2001 1392 1081 54.0% URUMQI 1722 1415 1338 77.7% YARRA12M 1476 1082 1022 69.2% --------------- --------- ----------- --------- ------ Station Total** 6074 4100 3757 61.9% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
