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.
