    This collection contains the Galileo spacecraft trajectory during the       
    Earth 2 flyby. The data have been derived from SPICE kernels at a 1         
    minute sample rate. The data are provided in both  Geocentric Solar         
    Ecliptic (GSE) and Geocentric Solar Magnetic (GSM) coordinates and are      
    given in units of earth radii where 1 Re = 6378 km.

    The Galileo trajectory data are being archived in 2 coordinate              
    systems. Geocentric Solar Ecliptic (GSE) and Geocentric Solar Magnetic      
    (GSM) are related earth centered coordinate systems. Both the GSE and       
    GSM X directions are taken along the Earth - Sun line, positive             
    towards the Sun. The GSE Z direction is parallel to the ecliptic            
    normal, positive northward, and Y completes the right-handed set            
    (towards dusk). For GSM, the X-Z plane contains the Earth's dipole          
    moment vector, positive northward, and Y completes the right-handed         
    set. GSE coordinates are commonly used for analyzing the solar wind         
    near the Earth and GSM coordinates are used when analyzing data             
    inside the Earth's bow shock.

    The data have been derived from the Galileo SPICE kernels using well        
    tested software from the SPICELIB and GLLSPICE subroutine libraries.        
    Each data point is computed using S/C and planetary ephemerides             
    computed at the time of the dataset sample (not interpolated).
