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
ORBIT COMBINATION AND EVALUATION STATISTICS:
--------------------------------------------
Table 1: Daily transformation of each centre to the combined IGS Rapid orbit
and clocks.
WRMS - RMS weighted by the centres SP3 header accuracy codes.
STA - Number of stations in the daily solutions.
Units: mas, ppb, meters, nano-sec, nano-sec/day.

(24 hours of adjusted orbits)
The "igr" and "IGR" columns are zero since all centres are
"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.
