LaunchVehicle: Spherical Elements: MeanOfEpoch

The mean equator mean equinox coordinate system evaluated at the epoch of the object.

Name Dimension Type Description
Time DateFormat Real Number Time.
Right Ascen LongitudeUnit Real Number The signed angle measured from the X axis to the projection of the position vector into the XY plane. The angle increases in the direction found by the right hand rule about the Z axis.
Declination AngleUnit Real Number The signed angle measured from the XY plane to the position vector, where positive angles are used for locations above the XY plane, and negative for those below.
Radius DistanceUnit Real Number The magnitude of the position vector (i.e. the radius vector).
Horiz Flt Path Ang AngleUnit Real Number The angle between the position vector and the plane whose normal is the velocity vector.
Inertial Flt Path Azi LongitudeUnit Real Number The angle, measured in the plane perpendicular to the position vector, between the local north direction and the projection of the velocity vector onto that plane, measured as positive moving toward local east.
Inertial Vel Rate Real Number The magnitude of the velocity vector, as observed in the coordinate system.
