The Landsat 7 ground system consists of both Landsat 7 unique components as well as institutional services. The unique components include the Mission Operations Center (MOC), Landsat Ground Station (LGS), Landsat Processing System (LPS), the Image Assessment System (IAS), the Level 1 Product Generation System (LPGS), the EROS Data Center Distributed Active Archive Center (LP-DAAC), and the international ground stations (IGS).

The institutional support systems consist of the Landsat Ground Network (LGN), Space Network (SN), The National Centers for Environmental Prediction (NCEP), The Flight Dynamics Facility (FDF), and the NASA Integrated Support Network (NISN).

The ground system context diagram illustrates both unique and institutional components and their data flow relationships end-to-end.
