We have included data from this satellite for days 103-105 (Apr 13-15) only. Additionally, IGS Mail Message 572 indicates that PRN03/GPS11 is expected to be permanently unsuable as of day 103. This satellite no longer appears in our solutions beginning with jpl07443.sp3, the corresponding orbit file for this day. According to IGS Mail Message 568, the antenna at ALBH was changed on day 104 (Apr 14). Also, the inclusion of data from NLIB caused an excessive number of outliers in the analysis of day 106. We have deleted these sites from our processing on the corresponding days. WARNING: Data from PRN06 have been excluded for days 099-102 and 106 due to maneuvering. WARNING: Data from ALBH have been excluded for day 104 due to an antenna change. WARNING: Data from NLIB have been excluded for day 106. WARNING: No data from PRN03 as of day 103; satellite out of service. WARNING: Little data from PRN13 on day 101.
