Data Providers: Satellite: CloseApproachByMinRange

The results produced by using the close approach tool, identifying vehicles that pass within a specified minimum range of the object. The data is sorted according to the minimum range. Also reports information concerning launch window blackout intervals when that capability is used.

Name	Dimension	Type	Description
Object Name	Unitless	Text	The names of the secondary object involved in the close approach event.
SSC Number	Unitless	Integer	The SSC number identifier from the TLE of an object having a close approach event.
Start Time	DateFormat	Real Number	The start time of the event.
End Time	DateFormat	Real Number	The stop time of the event.
Min Range	DistanceUnit	Real Number	The range (i.e., distance between the primary and secondary object) at the time of close approach.
Min Range Time	DateFormat	Real Number	The time at which the minimum range occurs.
Window Blackout Start	DateFormat	Real Number or Text	The start time of a launch window blackout interval. Only valid if the launch window capability has been used. During a launch window blackout interval, the vehicle will have a close approach with some secondary vehicle if it were to be launched during that interval.
Window Blackout Stop	DateFormat	Real Number or Text	The start time of a launch window blackout interval. Only valid if the launch window capability has been used. During a launch window blackout interval, the vehicle will have a close approach with some secondary vehicle if it were to be launched during that interval.
Window Blackout Duration	TimeUnit	Real Number or Text	The duration of the window blackout.
Min Range Launch Time	DateFormat	Real Number or Text	The launch time that produces the minimum range to the secondary. Only valid if the launch window capability has been used. During a launch window blackout interval, the vehicle will have a close approach with some secondary vehicle if it were to be launched during that interval.
Start Time Past Launch	TimeUnit	Real Number	The relative time since launch time, of the start time when the earliest close approach event occurs with the secondary. Only valid if the launch window capability has been used. During a launch window blackout interval, the vehicle will have a close approach with some secondary vehicle if it were to be launched during that interval.
End Time Past Launch	TimeUnit	Real Number	The relative time since launch time, of the stop time when the latest close approach event occurs with the secondary. Only valid if the launch window capability has been used. During a launch window blackout interval, the vehicle will have a close approach with some secondary vehicle if it were to be launched during that interval.
Duration	TimeUnit	Real Number	The duration of the event.
Time of Min Range Past Launch	TimeUnit	Real Number	The duration, measured from the launch time, at which the minimum range considering all secondary occurs.
