   This collection contains the Galileo spacecraft trajectory during the      
   interplanetary cruise. The data have been derived from SPICE kernels at    
   a 1 minute sample rate. The data are provided in RTN coordinates.

    The Galileo trajectory are being archived in fixed heliocentric           
    coordinates. The R component is the Sun->spacecraft range given in        
    units of Au (149674000 km). LAT is the solar latitude given in units      
    of degrees and measured from the ecliptic plane. LON is the solar east    
    longitude measured from the First Point of Aries(1950).

  ============                                                                
    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).
