Author: AC Coordinator / AIUB/CODE Ultra Rapid IGS Orbit Comparison - Week 1186 Day: 1 Hour: 00 (Sep 30, 2002) Contacts: R. Weber (rweber@luna.tuwien.ac.at), H. Bock (bock@aiub.unibe.ch), R. Dach (dach@aiub.unibe.ch) 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 on IGS Ultra Rapid Orbit Comparison: 1. The following Ultra-rapid orbits were excluded from the combination but kept for statistics: -> Centre: COU EMU ESU GFU SIU USU IGU _______________________________________________________________________________ Table 1: Daily transformation of each centre to the combined IGS Rapid orbit and clocks (IGR). WRMS - RMS weighted by the centres SP3 header accuracy codes. STA - Number of stations in the daily solutions. Units: meters, mas, ppb, nano-sec, nano-sec/day.

The "igr" and "IGR" columns are zero since all centres are compared to the "igr" solution. Eclipsing satellites are flagged with and "E" beside the PRN number. "MEDI" stands for median of the centre's satellite RMS. Units: cm.
