Data Center Description
The Satellite Situation Center (SSC) is an operational element of the National Space Science Data Center (NSSDC) and World Data Center for Satellite Information (WDC/SI) at NASA Goddard Space Flight Center in Greenbelt, Maryland. The SSC is further supported by software development staff in the Space Physics Data Facility at NASA Goddard. SSC routinely compiles, maintains and distributes information from a data base of satellite orbital elements and cartesian coordinates for space science satellites from launch reports issued by United States Space Command (USSPACECOM) and other U.S. and foreign agencies dessiminating satellite launch information. Related support services are provided to space science program offices, flight projects and individual investigators. Support is provided through NSSDC for domestic users and through WDC/SI for international users. Monthly reports on new satellite launches are published for the international Committee on Space Research (COSPAR) in the SPACEWARN Bulletin.
On-line versions of the SPACEWARN Bulletin and information on orbital elements and heliocentric coordinates for active space science satellites are available (http://nssdc.gsfc.nasa.gov/spacewarn/)
The software and associated database of Satellite Situation Center Web (SSCWeb) together form a system to cast geocentric spacecraft location information into a framework of (empirical) geophysical regions and mappings of spacecraft locations along lines of the Earth's magnetic field. This capability is one key to mission science planning (both single missions and coordinated observations of multiple spacecraft with ground-based investigations) and to subsequent multi-mission data analysis. This system directly supports the operational SSC and ISTP's Science Planning and Operations Facility (SPOF).
