U.S. ground stations in South Dakota and Alaska, as well as international ground stations in Norway and Australia, serve as the primary data capture facilities for the USGS Landsat satellite image archive.

The Landsat Ground Station (LGS) is located at the U.S. Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center in Sioux Falls, South Dakota. LGS supports both the Landsat 7 and Landsat 8 missions.

The Svalbard (SGS) ground station is located at the SvalSat facility in Svalbard, Norway. SGS supports both the Landsat 7 and Landsat 8 missions.

The Alice Springs (ASN) ground station is located at the Geoscience Australia facility in Alice Springs, Australia. ASN supports the Landsat 7 mission.

The North Pole (NPA) ground station is located at the North Pole Satellite Station in North Pole, Alaska. NPA supports the Landsat 7 mission.

The Gilmore Creek (GLC) ground station is located at the National Oceanic and Atmospheric Administration (NOAA) facility near Fairbanks, Alaska. GLC supports the Landsat 8 mission.

Landsat 8 Operations

The three ground receiving stations that make up the Landsat 8 USGS Ground Network are located in Sioux Falls, South Dakota; Gilmore Creek, Alaska; and Svalbard, Norway. These receiving stations are responsible for downlinking the satellite telemetry (via S-band Radio Frequency (RF) link) and science data (via X-band RF link) that feeds the USGS Landsat data archive. The stations can also uplink commands to the satellite.

The X-band is used to transmit both real-time and recorded Landsat 8 science data, which are then transferred from the stations as Mission Data to the Data Processing and Archive System (DPAS) located at the USGS EROS Center in Sioux Falls, South Dakota.

Additionally, each station supports the routing of S-band uplink communications to the Observatory and the routing of downlink telemetry spacecraft health and safety monitoring communications to the Mission Operation Center (MOC) located at the NASA Goddard Space Flight Center (GSFC) in Greenbelt, Maryland.

The NASA Tracking Data and Relay Satellite System (TDRSS) also provides housekeeping support for Landsat 8.

Landsat 7 Operations

The four ground receiving stations that make up the Landsat 7 USGS Ground Network are located in Sioux Falls, South Dakota; North Pole, Alaska; Alice Springs, Australia; and Svalbard, Norway. These sites receive both the science data (via X-band RF link) and the spacecraft housekeeping data (via S-band RF link).

The X-band is used to transmit both real-time and recorded Landsat 7 science data, which are then transferred from the stations as Raw Computer Compatible (RCC) files to the Landsat 7 Processing System (LPS), located at the USGS EROS Center in Sioux Falls, South Dakota.

Additionally, LGS, SGS, and NPA support the routing of S-band uplink communications to the Observatory and the routing of downlink telemetry spacecraft health and safety monitoring communications to the Mission Operation Center (MOC) located at GSFC in Greenbelt, Maryland. Downlink telemetry communications are also supported at ASN.

The NASA Tracking Data and Relay Satellite System (TDRSS) also provides housekeeping support for Landsat 7.
