Y completes the right-handed system. GSM : Geocentric Solar Magnetospheric - This system has its X axis towards the Sun and its Z axis is the projection of the Earth's magnetic dipole axis (positive North) on to the plane perpendicular to the X axis. Y completes the right-handed system. spase://SMWG/Person/Elena.Budnik MetadataContact spase://SMWG/Repository/CDPP/AMDA Online Open http://amda.cdpp.eu NetCDF PSA spase://CNES/Instrument/CDPP-AMDA/Rosetta/Ephemeris Ephemeris 2005-03-03T00:00:00Z 2005-03-06T23:59:00Z PT60S Earth xyz_gse ros_xyz_earth1 pos.bodyrc;instr.obsty Re Cartesian GSE TimeSeries 3 x 1 ros_xyz_earth1(0) y 2 ros_xyz_earth1(1) z 3 ros_xyz_earth1(2) Positional distance ros-earth ros_r_earth1 pos.bodyrc;instr.obsty Re Positional
