public class FieldApsideDetector<T extends RealFieldElement<T>> extends FieldAbstractDetector<FieldApsideDetector<T>,T>
This class finds apside crossing events (i.e. apogee or perigee crossing).
The default implementation behavior is to continue
propagation at apogee crossing and to stop propagation
at perigee crossing. This can be changed by calling
FieldAbstractDetector.withHandler(FieldEventHandler) after construction.
Beware that apside detection will fail for almost circular orbits. If
for example an apside detector is used to trigger an ImpulseManeuver and the maneuver
change the orbit shape to circular, then the detector may completely fail just
after the maneuver has been performed!
