Constructor Detail

CustomAltitudeDetector

public CustomAltitudeDetector(double altitude,
                      CustomAltitudeDetector.AltitudeDetectionChoice altitudeDetectionChoice,
                      org.orekit.bodies.ExtendedOneAxisEllipsoid bodyShape,
                      int triggerFrom,
                      Integer triggerStep,
                      Integer triggerTo)

Constructor with target altitude and body shape. maxCheck (600 s), threshold (1.0e-6 s) and action (RESET_STATE) by default.

Parameters:

altitude - target altitude.

altitudeDetectionChoice - altitude detection choice

bodyShape - central body shape.

triggerFrom - count at/from which the single/multiple event must be triggered.

triggerStep - step every which the multiple event must be triggered. If null, the event will be triggered only once at the occurrence given by triggerFrom.

triggerTo - count until which the multiple event must be triggered. If null, the event will be triggered until the end of propagation.

CustomAltitudeDetector

public CustomAltitudeDetector(double altitude,
                      CustomAltitudeDetector.AltitudeDetectionChoice altitudeDetectionChoice,
                      org.orekit.bodies.ExtendedOneAxisEllipsoid bodyShape,
                      int triggerFrom,
                      Integer triggerStep,
                      Integer triggerTo,
                      double maxCheck,
                      double threshold,
                      org.orekit.propagation.events.EventDetector.Action action)

Constructor with complete data.

Parameters:

altitude - target altitude.

altitudeDetectionChoice - altitude detection choice

bodyShape - central body shape.

maxCheck - maximum checking interval (s).

triggerFrom - count at/from which the single/multiple event must be triggered.

triggerStep - step every which the multiple event must be triggered. If null, the event will be triggered only once at the occurrence given by triggerFrom.

triggerTo - count until which the multiple event must be triggered. If null, the event will be triggered until the end of propagation.

threshold - convergence threshold (s).

action - action to be performed in case of event detection.

copy

public org.orekit.propagation.events.EventDetector copy()

Description copied from interface: CustomEventDetector

Returns a new instance of the current type of CustomEventDetector with the same attributes but for the action which is set to Action#CONTINUE. It is intended to be used to create the CodingEventDetector.

Specified by:

copy in interface CustomEventDetector

Returns:

a new instance with equal attributes but with Action#CONTINUE

getCodingEventDetector

public fr.cnes.sirius.patrius.events.CodingEventDetector getCodingEventDetector(String incEventString,
