Soehne Subject: Wk 0980 GFZ IGEX Analysis Report GFZ has analyzed IGEX data for week 0980. Although the results (i.e. orbit overlays) for the GLONASS satellites are not sufficient yet (up to some meter for special satellites, e.g. R11) and are not given here we like to present our analysis strategy for that week.
