FGS Workshop 2004, Höllenstein/Wettzell, October 27 - 29, 2004 Kinematic IGS Station Baseline ALGO-GODE (length 777 km) Double-differences with fixed ambiguities (Melbourne-Wübbena with narrow-laning) Differences between kinematic positions estimated every 30 s for GODE IGS station and weekly GODE coordinates All global products kept fixed. Similar results with troposphere estimation.
