IVS Analysis Report for AOV020 ($18FEB27XA) 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, Goddard Space Flight Center. Spoolfile source: interactive solve/nuSolve analysis.) Problems: X-band record #942 (KE-YG 02/28/17:22:25 1424-418) has the wrong ambiguity spacing, 33.3 nsec instead of 100.0. It has 8 channels though, like the rest of the X-band and Solve seems to work okay on it. KATH12M and YARRA12M are very noisy. KOGANEI has data only for the first ~11 hours; schedule was stopped due to some misunderstanding. WARK12M has data only for the last ~5 hours; some problem with staff scheduling. HOBART26 had no usable data because the receiver was inside the focus cabin rather than over the focal point. The solution gives large atmosphere adjustments, up to ~2 nsec at KATH12M. Gradients were not applied. Parameterization comments: None. Other comments: Preliminary release. The SYOWA data will not be available until after April 2019. ----------------------------------------- Session Statistics Observations: 2534 scheduled 952 correlated (in database) 758 recoverable (usable) 714 used Session fit: 79.729 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used HOBART26 766 NOT CORR NOT CORR 0.0% ISHIOKA 811 418 406 50.1% KASHIM11 570 315 295 51.8% KATH12M 708 310 291 41.1% KOGANEI 640 112 97 15.2% SYOWA 305 NOT CORR NOT CORR 0.0% WARK12M 617 87 82 13.3% YARRA12M 651 274 257 39.5% --------------- --------- ----------- --------- ------ Station Total** 2534 758 714 28.2% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
