Data Providers: Access: From Position Velocity: TrueOfEpoch

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

Name	Dimension	Type	Description
Time	DateFormat	Real Number	Time.
x	DistanceUnit	Real Number	The X component of the position vector.
y	DistanceUnit	Real Number	The Y component of the position vector.
z	DistanceUnit	Real Number	The Z component of the position vector.
Range	DistanceUnit	Real Number	The range (i.e., distance between the primary and secondary object) at the given time.
x/Range	Unitless	Real Number	The direction cosine for the X-axis.
y/Range	Unitless	Real Number	The direction cosine for the Y-axis.
z/Range	Unitless	Real Number	The direction cosine for the Z-axis.
xVel	Rate	Real Number	The X-component of velocity.
yVel	Rate	Real Number	The Y-component of velocity.
zVel	Rate	Real Number	The Z-component of velocity.
RelSpeed	Rate	Real Number	The magnitude of the velocity vector.
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	LatitudeUnit	Real Number	Declination of the displacement vector that locates selected point in the reference coordinate system. Represents the angle between the displacement vector and its projection onto the xy-plane of the reference coordinate system. The angle is positive when the displacement vector is directed toward positive z-axis of the reference coordinate system.
LightTimeDelay	TimeUnit	Real Number	The light time delay used in computing the base and target object’s location.
