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 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 2. Because of a maneuver, some satellites were excluded from the Prediction combination. The following table lists the maneuvered satellites: PRN | Date | Ref.
