Access: Rel Position Velocity: Fixed

A coordinate system attached to the central body and rotating with it.

Name Dimension Type Description
Time DateFormat Real Number Time.
x DistanceUnit Real Number The X component of the relative position vector.
y DistanceUnit Real Number The Y component of the relative position vector.
z DistanceUnit Real Number The Z component of the relative 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 of the relative position vector along the X-axis.
y/Range Unitless Real Number The direction cosine of the relative position vector along the Y-axis.
z/Range Unitless Real Number The direction cosine of the relative position vector along the Z-axis.
xVel Rate Real Number The X-component of the relative velocity.
yVel Rate Real Number The Y-component of the relative velocity.
zVel Rate Real Number The Z-component of the relative velocity.
RelSpeed Rate Real Number The magnitude of the relative 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 relative location.
