Member Value Description eCoordinateSystemUnknown -1 Represents coordinate system not supported by the Object Model eCoordinateSystemAlignmentAtEpoch 0 Alignment at Epoch: an inertial system coincident with ECF at the Coord Epoch. Often used to specify launch trajectories. eCoordinateSystemB1950 1 B1950: X points toward the mean vernal equinox and Z points along the mean rotation axis of the Earth at the beginning of the Besselian year 1950 and corresponds to 31 December 1949 22:09:07.2 or JD 2433282.423. eCoordinateSystemFixed 2 Fixed: X is fixed at 0 deg longitude, Y is fixed at 90 deg longitude, and Z is directed toward the north pole. eCoordinateSystemJ2000 3 J2000: X points toward the mean vernal equinox and Z points along the mean rotation axis of the Earth on 1 Jan 2000 at 12:00:00.00 TDB, which corresponds to JD 2451545.0 TDB. eCoordinateSystemMeanOfDate 4 Mean of Date: X points toward the mean vernal equinox and Z points along the mean rotation axis of the Earth at the Orbit Epoch. eCoordinateSystemMeanOfEpoch 5 Mean of Epoch: X points toward the mean vernal equinox and Z points along the mean rotation axis of the Earth at the Coord Epoch. eCoordinateSystemTEMEOfDate 6 TEME of Date: X points toward the mean vernal equinox and Z points along the true rotation axis of the Earth at the Orbit Epoch. eCoordinateSystemTEMEOfEpoch 7 TEME of Epoch: X points toward the mean vernal equinox and Z points along the true rotation axis of the Earth at the Coord Epoch. eCoordinateSystemTrueOfDate 8 True of Date: X points toward the true vernal equinox and Z points along the true rotation axis of the Earth at the Orbit Epoch. eCoordinateSystemTrueOfEpoch 9 True of Epoch: X points toward the true vernal equinox and Z points along the true rotation axis of the Earth at the Coord Epoch. eCoordinateSystemTrueOfRefDate 10 True of Ref Date: A special case of True of Epoch. Instead of the Coord Epoch, this system uses a Reference Date defined in the Integration Control page of the scenario's PODS properties. eCoordinateSystemICRF 11 ICRF: International Celestial Reference Frame. eCoordinateSystemMeanEarth 13 Mean Earth eCoordinateSystemFixedNoLibration 14 uses an analytic formula not modeling lunar libration eCoordinateSystemFixedIAU2003 15 Fixed_IAU2003 eCoordinateSystemPrincipalAxes421 16 PrincipalAxes_421 eCoordinateSystemPrincipalAxes403 17 PrincipalAxes_403 eCoordinateSystemInertial 18 Inertial eCoordinateSystemJ2000Ecliptic 19 The mean ecliptic system evaluated at the J2000 epoch. The mean ecliptic plane is defined as the rotation of the J2000 XY plane about the J2000 X axis by the mean obliquity defined using FK5 IAU76 theory. eCoordinateSystemTrueEclipticOfDate 21 The true ecliptic system, evaluated at each given time. The true ecliptic plane is defined as the rotation of the J2000 XY plane about the J2000 X axis by the true obliquity defined using FK5 IAU76 theory. eCoordinateSystemPrincipalAxes430 22 PrincipalAxes_430 - SemiMajorAxis
