COMBINATION STRATEGY:
---------------------
For a complete description of the combination strategy along with all tables
and statistics, please refer to the IGS Final Combination reports posted on
CDDIS within 13 days after the end of the GPS week.
REMARKS concerning the Ultra Rapid Orbit Comparison:
----------------------------------------------------
1. The following Ultra-rapid orbits were excluded from the combination but
kept for statistics:
-> Centre: COU EMU ESU GFU GOU SIU USU IGU
2. Because of a maneuver, some satellites were excluded from the Prediction
combination. The following table lists the maneuvered satellites:

Table 2: Daily fit for each satellite and each centre resulting from the
comparison of the individual solutions to the IGS Rapid solution.
(first 6 hours of the prediction)
The "igr" and "IGR" columns are zero since all centres are compared
to the "igr" solution. Eclipsing satellites are flagged with an "E"
beside the PRN number.
"MEDI" stands for median of the centre's satellite RMS.

Table 3: Daily fit for each satellite and each centre resulting from the
comparison of the individual solutions to the IGS Rapid solution.
(24 hours of adjusted orbits)
The "igr" and "IGR" columns are zero since all centres are compared
to the "igr" solution. Eclipsing satellites are flagged with an "E"
beside the PRN number.
"MEDI" stands for median of the centre's satellite RMS.
Remark: COU results for 06 UT are the prediction from the 00 UT
results, i.e. last 6 hours are predicted and
are therefore excluded from the comparison.
