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.) 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. YARRA12M's clock is very unstable with many small breaks. Eight breaks were used: 19:22, 22:42, 23:15, 23:45, 10:35, 11:00, 12:48 and 17:02 UTC. HOBART26 missed most of the first 8 hours. The log has a comment about servicing the receiver focus platform. KUNMING, YARRA12M and KOGANEI are very noisy. KOGANEI's log has many 'ONSOURCE status is SLEWING!' messages. Parameterization comments: None. Other comments: This is the refringed version. Originally there were many X-band subambiguities on KUNMING baselines. The refringed solution uses ~230 additional KUNMING observations. ----------------------------------------- Session Statistics Observations: 6074 scheduled 5531 correlated (in database) 4100 recoverable (usable) 3865 used Session fit: 62.726 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART26 1446 750 732 50.6% ISHIOKA 2028 1607 1513 74.6% KOGANEI 1946 732 715 36.7% KOKEE 1529 1222 1185 77.5% KUNMING 2001 1392 1232 61.6% URUMQI 1722 1415 1326 77.0% YARRA12M 1476 1082 1027 69.6% --------------- --------- ----------- --------- ------ Station Total** 6074 4100 3865 63.6% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
