Jefferson Subject: JPL Analysis Report (week 723) ****************************************************************************** JPL ANALYSIS REPORT GPS-WEEK 0723 (DAYS 318-324, DATES 14-11-93 TO 20-11-93) ****************************************************************************** Submitted by D C Jefferson, J F Zumberge, G Blewitt, M B Heflin, F H Webb all at the Jet Propulsion Laboratory, California Institute of Technology, Pasadena, CA 91109. The following files have been sent to the CDDIS: ______________________________________________________________________________ filename contents ______________________________________________________________________________ jpl07237.sum This text file. jpl07237.erp Earth rotation parameters for GPS week 723. jpl0723[0-6].sp3 GPS ephemerides for GPS week 723, sp3 format. ______________________________________________________________________________ Following our previous experiences with HOBA (Hobart, Tasmania), we have elected to exclude this site from our processing for the entire week of analysis. Also, as indicated in the Ground Station Inclusion Table, ALGO (Algonquin Park, Canada) had an atypically small amount of data for day 323 (Nov 19). We have subsequently changed our reference clock to FAIR (Fairbanks, Alaska) for this day only. The larger-than-normal values for clock repeatabilities on days 322-324 presumably reflect a 1 microsecond difference between the ALGO and FAIR clocks. WARNING: Data from HOBA have been excluded the entire GPS week 723. WARNING: FAIR (not ALGO) was used as the reference clock for day 323 (Nov 19).
