The following files have been sent to the CDDIS: ______________________________________________________________________________ filename contents ______________________________________________________________________________ jpl07227.sum This text file. jpl07227.erp Earth rotation parameters for GPS week 722. jpl0722[0-6].sp3 GPS ephemerides for GPS week 722, sp3 format. ______________________________________________________________________________ Due to anti-spoofing, various receivers were tracking in cross-correlated mode on days 312 and 313 (November 8 and 9). Our A-S strategy was used for the analyses of these two days only; see jpl07147.sum for details. Tracking data from HOBA (Hobart, Tasmania) and KOUR (Kourou, Fr. Guiana) have been deleted for the entire week of analysis (no data for KOUR available on day 313). Inclusion of one or both of these sites has caused an excessive number of outliers in our solutions. WARNING: Data from HOBA and KOUR have been excluded the entire GPS week 722.
