/*
 * STRUCT: SRM_GSE_3D_PARAMETERS
 *
 *   No parameters are needed to define the Geocentric Solar Ecliptic (GSE) 3D
 *   Spatial Reference Frame (SRF), but a struct is declared for it anyway, to
 *   parallel the struct definitions of the other SRFs. The associated ORM/ERM
 *   is defined by the WGS-84 ellipsoid.
