2.4.1 spase://CNES/NumericalData/CDPP-AMDA/Ephemerides/saturn-orb-all Saturn 2018-09-18T11:40:13Z Heliocentric Inertial (HCI) Frame : * The solar rotation axis is the primary vector: the Z axis points in the solar north direction; * The solar ascending node on the ecliptic of J2000 forms the X axis. * The Y axis is Z cross X, completing the right-handed reference frame. Heliocentric Earth Ecliptic (HEE) Frame : * The position of the earth relative to the sun is the primary vector: the X axis points from the sun to the earth. * The northern surface normal to the mean ecliptic of date is the secondary vector: the Z axis is the component of this vector orthogonal to the X axis. * The Y axis is Z cross X, completing the right-handed reference frame. Solar longitude (Ls) : * The solar longitude Ls is the Planet-Sun angle, measured from the Northern Hemisphere spring equinox where Ls=0. Ls=90 thus corresponds to northern summer solstice, just as Ls=180 marks the northern autumn equinox and Ls=270 the northern winter solstice. spase://CNES/Person/CDPP-AMDA/NAIF PrincipalInvestigator spase://SMWG/Repository/CDPP/AMDA Online Open CDPP/AMDA HAPI Server https://amda.irap.omp.eu/service/hapi saturn-orb-all Web Service to this product using the HAPI interface.
