Mean Orbit Repeatability (see table below): 20.4 cm

According to the file nanu1995.mes obtained from the IGS CBIS, PRN25 was
unusable on day 139 (May 19) due to maintenance/repositioning.  Data from this
satellite did not meet our initial convergence criteria for this day, as well
as adjacent days (138 and 140), and were excluded from these days' processing.

Please note that at the time this report is written, the analysis of day 141
(May 21, week 802) has not been done.  Hence, the decimeter level precision in
the last column of the orbit repeatability table, which only reflects overlap 
quality with the previous day.

Due to potential problems, data from stations mentioned below were not
considered for use in the global solution for the day indicated.  (For
geographical reasons, they may not have been used in any case.)

WARNING: Data from SHAO, TAIW excluded on day 134 (May 14).
WARNING: Data from TAIW excluded on day 135 (May 15).
WARNING: Data from METS, TAIW excluded on day 136 (May 16).
WARNING: Data from BRUS, MATE, LAMA, TAIW, TSKB, ZIMM excluded on day 137                (May 17).
WARNING: Data from PRN25 excluded on days 138-140 (May 18-20) due to a maneuver.
WARNING: Data from BRUS, GUAM, TAIW, WHC1 excluded on day 138 (May 18).
WARNING: Data from TAIW, WETT, WHC1 excluded on day 139 (May 19).
WARNING: Data from AOA1, OAT2, LAMA, TAIW excluded on day 140 (May 20).

In the following table, UT1R-UTC are the integrated values based on estimated
LODR values in the adjacent column.  See IGS Report No. 1498 (jpl07827.sum)
