Dataset Overview ================ This dataset 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. Data Columns: time S/C event time (UT) given in seconds since 1966 scet S/C event time (UT) given in the form yyyy ddd mon day hh:mm:ss.sss X S/C position X component in GSE or GSM coordinate Y_gse S/C position Y component in GSE coordinates Z_gse S/C position Z component in GSE coordinates Y_gsm S/C position Y component in GSM coordinates Z_gsm S/C position Z component in GSM coordinates Coordinate Systems ================== 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. Data Processing =============== These data have been derived from the PDS dataset: 'GO-J-SPICE-6-SPK-E2-V1.0' The SPK file used to dervied this product was: 'GLL920818.SPK' Data Quality ============ 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).
