The Satellite Situation Center Web (SSCWeb) Service is operated by NASA's Space Physics Data Facility (SPDF). It was developed jointly by SPDF and the National Space Science Data Center (NSSDC) to support a range of NASA science programs and to fulfill key international NASA responsibilities including those of NSSDC and the World Data Center-A for Rockets and Satellites.
The software and associated database of 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.
Try out our browser-based 4D Orbit Viewer to display the SSC spacecraft orbits in an interactive 3-D animation tool (short demo). Please let us know of any questions, suggestions, and comments.**

4D Orbit Viewer provides an interactive 4-D animation of spacecraft orbits over time.
Locator provides a table of spacecraft coordinate locations in various coordinate systems with other location-related information.(THEMIS Saved Examples)
Locator Graphics generates 2-D plots of the locations of multiple spacecraft as orbit, mapped and time series plots.(THEMIS Saved Examples).
The Query component provides two query matching options: magnetospheric region occupancy and magnetic field line tracing. The region query lists the entry and exit times during which specified satellite(s) were in particular magnetospheric regions. The trace query identifies periods when one or more spacecraft are on the same magnetic flux tube of force, or periods when one or more spacecraft occupy a field line which traces down to a specified ground station.(THEMIS Saved Examples)
Convert between coordinate systems and trace a point along the corresponding magnetic field line.
