PRN22/GPS22 has been deleted for the entire week of analysis, see jpl06917.sum
for details. Also, according to the file gpsn2.txt obtained from tycho.usno.mil
PRN20/GPS20 was scheduled unusable from 08:47 UT to 18:01 UT on day 103 (April
13). We have therefore deleted this satellite from processing on this day only.
PRN29 exhibited unmodelled behavior on day 103 as well. We have thus chosen to
deweight data from this satellite for April 13 only.
WARNING: Due to the maneuver of PRN20/GPS20, data from this satellite have been deleted for day 103 (Apr 13).
WARNING: Data from PRN22/GPS22 have been deleted for the entire GPSweek 692.
WARNING: Data from PRN29/GPS29 have been deweighted for day 103 (April 13).
