public class AltitudeDetector extends AbstractDetector<AltitudeDetector>
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
AbstractDetector.withHandler(EventHandler) after construction.

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

double altitude,
BodyShape bodyShape)
This simple constructor takes default value for convergence threshold
(AbstractDetector.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.
