Data Providers: Missile: Mixed Spherical Elements: TrueOfEpoch

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

Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
Detic Lat	AngleUnit	Real Number	The detic latitude (i.e., angle between the detic subpoint's surface normal vector and the XY plane.)
Detic Lon	LongitudeUnit	Real Number	The detic longitude (i.e., angle from the X-axis locating the projection of the detic subpoint's surface normal vector onto the XY plane.) Longitude increases in the direction found using the right-hand rule about the Z-axis.
Detic Alt	DistanceUnit	Real Number	The altitude value (i.e., magnitude of the relative position vector between the object and its detic subpoint).
Horiz Flt Path Ang	AngleUnit	Real Number	The angle between the position vector and the plane whose normal is the velocity vector.
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.
Velocity	Rate	Real Number	The magnitude of the velocity vector, as observed in the object's central body fixed coordinate system.
