According to the file nanu1994.mes obtained from the IGS CBIS, PRN20 was
declared unusable from 04:30 UT on day 239 (Aug 27) until 15:13 UT on day 242
(Aug 30).  Although this satellite was used in our processing for day 240
(Aug 28), it has been removed from the the corresponding sp3 orbit file.

Also, PRN05 was reported unusable from 07:30 UT on day 245 (Sep 2) until 00:49
on day 246 (Sep 3) for repostioning.  We have excluded this satellite from
our processing on both days.

WARNING: Little data from PRN20 day 240 (Aug 28); excluded from jpl07640.sp3.
WARNING: Data from PRN05 excluded days 245 and 246 (Sep 2,3) due to a maneuver.
WARNING: Data from MATE excluded days 243-246 (Aug 31-Sep 3).
WARNING: Data from BRMU and GODE  excluded day 242 (Aug 30).

In the following table, UT1R-UTC are the assumed nominal values from IERS
Bulletin-B predicts; estimated LODR values are also included.  See IGS Mail
Message 97 for details.
