Summary

Abstract:
The software and associated database of the 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). The SSC is a facility operated by NSSDC to fulfill key international responsibilities such as the SpaceWarn bulletins and to assist users in a particular magnetospheric region, allow a choice from a variety of internal and external magnetic field models for field-line tracing options, plot spacecraft trajectories, and perform conversions among geocentric and magnetic coordinate systems. magnetic coordinate systems. The SSC and NSSDC also support a set of pages for heliospheric spacecraft, planet and comet trajectories and pages for specific access to various space physics models including IGRF/DGRF and CGM coordinate transformations. The SSC also maintains a set of useful processed products and information. The SSC data products consist of the Locator graphics component which provides the ability to plot the orbits of multiple spacecraft. In addition to orbit plots, mapped and time series plots can also be generated. An interactive 3-D orbit viewer is also available to provide the user with the capability to select spacecraft/source and time ranges of interest, and see their orbits represented as an interactive 3-D animation. A Locator Tabular provides tabular information. As tabular output, the spacecraft's coordinate location can be listed in a variety of coordinate systems, as well as other location related items 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. The Satellite Situation Center (SSC) can be accessed through the "http://sscweb.gsfc.nasa.gov/" |
