Following the Trail of TIRS Technology onto a CapSat

An advanced photodetector camera that traces its heritage to one now flying on Landsat 8 is being studied as a potential payload on a conceptual satellite (CapSat) system purposely designed to take advantage of the expected boom in secondary-payload launch opportunities.

Landsat 8 Data Processing and Archive System (DPAS)

The USGS is also developing the DPAS to manage the mission data transmitted from the LDCM observatory. The DPAS will be operated at EROS along with the rest of its Landsat data archive and it will consist of several subsystems: Storage and Archive (SA), Ingest System (IS), Subsetter System (SS), Image Assessment System (IAS), Level 1 Product Generation System (LPGS), and User Portal (UP). These subsystems will work together to ingest, store, and archive LDCM data and will also generate LDCM data products for distribution.

Landsat 8 Mission Operations Center (MOC)

A flight operations team (FOT) will operate two computer systems within the MOC, the Collection Activity Planning Element (CAPE) and the Mission Operations Element (MOE). The CAPE will plan science data collection by building activity requests for the LDCM imaging sensors each day. The MOE will translate the activity requests into software command loads transmitted to the observatory.
