Author: AC Coordinator / GFZ Potsdam Ultra Rapid IGS Orbit Comparison - Week 1242 Day: 4 Hour: 00 (Oct 30, 2003) Contacts: G. Gendt (gendt@gfz-potsdam.de), Th. Nischan (nisn@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 on IGS Ultra Rapid Orbit Comparison: 1. The following Ultra-rapid orbits were excluded from the combination but kept for statistics: -> Centre: COU EMU GFU _______________________________________________________________________________ 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.
