Nischan ( nisn at gfz-potsdam.de) 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.

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. Units: cm.
