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.
