FieldEventDetector<T>public class FieldAltitudeDetector<T extends RealFieldElement<T>> extends FieldAbstractDetector<FieldAltitudeDetector<T>,T>
This class finds altitude events (i.e. satellite crossing a predefined altitude level above ground).
The default implementation behavior is to continue propagation when ascending and to stop
propagation when descending. This can be changed by calling
FieldAbstractDetector.withHandler(FieldEventHandler) after construction.

This simple constructor takes default values for maximal checking
interval (FieldAbstractDetector.DEFAULT_MAXCHECK) and convergence threshold
(FieldAbstractDetector.DEFAULT_THRESHOLD).

This simple constructor takes default value for convergence threshold
(FieldAbstractDetector.DEFAULT_THRESHOLD).
The maximal interval between altitude checks should be smaller than the half duration of the minimal pass to handle, otherwise some short passes could be missed.
