IVS Analysis Report for VO1090 ($21MAR31VG) 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: interactive solve/nuSolve analysis.) Problems: KOKEE12M Two separate cases when elevation drive went to inactive and brake on for unknow reason after reaching source or very close to reaching source, antenna controller had to be power cycled for antenna to become operational. Missed ~7 minutes due to unknown elevation drive issue. Missed few scans due to unknown elevation drive issue. (10 scans). MACGO12M Observed with warm front end - known issue. Missed ~12 minutes due to rdbe communication errors (090-1808 -- 090-1820b). Reboot of rdbes to solve the issue RAEGYEB Removed channels X01LX/Y, X02LX/Y, X03LX/Y, X04LX/Y, X07LX/Y, X11LX/Y, X12LX/Y and X14LX/Y due to unstable phase cal behavior. The station has bi-modal behavior of residuals, many observations are deselected. Parameterization comments: None. Other comments: None. ----------------------------------------- Session statistics Observations: 19636 scheduled 19514 correlated (in database) 19242 recoverable (usable) 16831 used Session fit: 21.227 ps ----------------------------------------- Station Performance Number of Observations Scheduled Recoverable* Used % of scheduled obs used GGAO12M 4437 4406 4067 91.7% ISHIOKA 4357 4305 3851 88.4% KOKEE12M 3072 2997 2802 91.2% MACGO12M 4563 4469 4151 91.0% ONSA13NE 4703 4508 3928 83.5% ONSA13SW 4686 4479 3843 82.0% RAEGYEB 4618 4543 3045 65.9% WESTFORD 4116 4084 3751 91.1% WETTZ13S 4720 4693 4224 89.5% --------------- --------- ----------- --------- ------ Station Total** 19636 19242 16831 85.7% * Recoverable: can be included in the solution. ** Total includes distinct observations only.
