  Data Set Overview
  =================
    This dataset contains the Galileo spacecraft trajectory during the
    Venus flyby. The data have been derived from SPICE kernels at a 1
    minute sample rate. The data are provided in Venus Solar Orbital
    (VSO) coordinates and are given in units of Venus radii where 1 Rv =
    6052 km.

    Z        S/C position Z component in VSO coordinates <Rv>


  Coordinate Systems
  ==================
    The Galileo trajectory data are being archived in the Venus Solar
    Orbital (VSO) coordinate system. The VSO coordinate system is
    basically the Geocentric Solar Ecliptic (GSE) coordinate system
    defined appropriately for Venus.  The VSO X direction is taken along
    the Venus - Sun line, positive towards the Sun. The VSO Z direction
    is parallel to the normal to the Venus orbital plane about the Sun,
    positive northward, and Y completes the right-handed set (towards
    dusk).


    Data Processing
    ===============
    The trajectory has been derived from a Galileo SPK kernel.
    This kernel was obtained by the PDS-PPI node from the PDS-NAIF
    node. The code which produced the trajectory data was developed and
    executed at PDS-PPI. This code utilized SPICE routines which were
    developed at and distributed by PDS-NAIF. Both SPICE kernels and
    code may be available through PDS-NAIF."

  Confidence Level Overview
  =========================
    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)."
