NameDescription
TrueOfDateRotatingA variation of the Fixed system where pole wander is ignored. The equator is the same as the TrueOfDate equator and the frame spins about the TrueOfDate z-axis.

TimeDateReal Number or TextTime.
AzimuthLongitudeReal Number or TextDihedral angle between north vector and velocity vector about the detic nadir vector. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
ElevationAngleReal Number or TextAngle between the velocity vector and the local horizontal plane. The velocity vector is the velocity of the object, as observed in the object's central body fixed coordinate system.
Horiz RateRateReal NumberSpeed in the local horizontal plane, as observed in the object's central body fixed coordinate system.
VelocityRateReal NumberThe magnitude of the velocity vector, as observed in the object's central body fixed coordinate system.
