Data Provider Elements

NameDimensionTypeDescription
Object NameUnitlessTextThe names of the secondary object involved in the close approach event.
SSC NumberUnitlessIntegerThe SSC number identifier from the TLE of an object having a close approach event.
Start TimeDateReal Number or TextThe start time of the event.
End TimeDateReal Number or TextThe stop time of the event.
Min RangeDistanceReal NumberThe range (i.e., distance between the primary and secondary object) at the time of close approach.
Min Range TimeDateReal Number or TextThe time at which the minimum range occurs.
Window Blackout StartDateReal Number or TextThe 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 StopDateReal Number or TextThe 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 DurationTimeReal Number or TextThe duration of the window blackout.
Min Range Launch TimeDateReal Number or TextThe 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 LaunchTimeReal NumberThe 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 LaunchTimeReal NumberThe 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.
DurationTimeReal NumberThe duration of the event. If the launch window capability has been used, then the duration is the difference between End Time Past Launch and Start Time Past Launch.
Time of Min Range Past LaunchTimeReal NumberThe duration, measured from the launch time, at which the minimum range considering all secondary occurs.
