Type: IOrbit
The satellite orbit.
Type: System..::..Double
The search start time, in minutes-past-epoch format.
Type: System..::..Double
The search end time, in minutes-past-epoch format.

Return Value

The time, in minutes-past-epoch, that the orbit decays, else null to indicate no decay condition detected.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type IOrbit. When you use instance method syntax to call this method, omit the first parameter. For more information, see or .


For best results, always use a t1 value equal to the satellite orbit's epoch time.
