| DATA_SET_DESCRIPTION |
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. Data ==== ------------------------------------------------------------------ Table 1. Data record structure ------------------------------------------------------------------ Column Description ------------------------------------------------------------------ year Year = 1990 day Day of year (40 or 41) sec Second of day X S/C position X component in VSO coordinates Y S/C position Y component in VSO coordinates Z S/C position Z component in VSO coordinates 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_NOTE |
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).
