TCA Ephemeris Data

Reports data at the time of closest approach over each strand access interval, for all strands that have just two objects. The 'From-object' is the first object listed in the strand; the 'To-object' is the second object listed. Values are reported for each strand access interval that lies within the requested report intervals.

Available for these objects: Chain

Type: Interval data.

Availability: Reports

Name	Dimension	Type	Description
Strand Name	Unitless	Text	The name of object.
Time of Closest Approach	Date	Real Number or Text	The time during each strand access interval at which the closest approach occurs (i.e., the range between the objects is at a minimum).
Range	Distance	Real Number	The range (i.e., distance between the primary and secondary object) at the given time.
From Object-X	Distance	Real Number	The X component of the position vector at the time of closest approach of the From-object expressed in the object's central body Fixed coordinate system.
From Object-Y	Distance	Real Number	The Y component of the position vector at the time of closest approach of the From-object expressed in the object's central body Fixed coordinate system.
From Object-Z	Distance	Real Number	The Z component of the position vector at the time of closest approach of the From-object expressed in the object's central body Fixed coordinate system.
From Object-vX	Rate	Real Number	The X component of the velocity vector at the time of closest approach of the From-object as observed in the object's central body Fixed coordinate system and expressed using those components.
From Object-vY	Rate	Real Number	The Y component of the velocity vector at the time of closest approach of the From-object as observed in the object's central body Fixed coordinate system and expressed using those components.
From Object-vZ	Rate	Real Number	The Z component of the velocity vector at the time of closest approach of the From-object as observed in the object's central body Fixed coordinate system and expressed using those components.
To Object-X	Distance	Real Number	The X component of the position vector at the time of closest approach of the To-object expressed in the object's central body Fixed coordinate system.
To Object-Y	Distance	Real Number	The Y component of the position vector at the time of closest approach of the To-object expressed in the object's central body Fixed coordinate system.
To Object-Z	Distance	Real Number	The Z component of the position vector at the time of closest approach of the To-object expressed in the object's central body Fixed coordinate system.
To Object-vX	Rate	Real Number	The X component of the velocity vector at the time of closest approach of the To-object as observed in the object's central body Fixed coordinate system and expressed using those components.
To Object-vY	Rate	Real Number	The Y component of the velocity vector at the time of closest approach of the To-object as observed in the object's central body Fixed coordinate system and expressed using those components.
To Object-vZ	Rate	Real Number	The Z component of the velocity vector at the time of closest approach of the To-object as observed in the object's central body Fixed coordinate system and expressed using those components.
