All Implemented Interfaces:

EventDetector, Serializable

public class NadirSolarIncidenceDetector
extends AbstractSolarIncidenceDetector

Spacecraft's nadir point solar incidence detector.

The solar incidence is the angle between the nadir-satellite vector and the nadir-sun vector.
This detector discriminates among increasing g events and decreasing g events.
The default implementation is to stop propagation when the reference solar incidence is reached. This can be changed by using provided constructors.

This detector can take into account signal propagation duration through AbstractSignalPropagationDetector.setPropagationDelayType(PropagationDelayType, Frame) (default is signal being instantaneous).

state - the current state information

Returns:

the interest point

Throws:

PatriusException - if some specific error occurs

copy

public EventDetector copy()

A copy of the detector. By default copy is deep. If not, detector javadoc will specify which attribute is not fully copied. In that case, the attribute reference is passed.

The following attributes are not deeply copied:

• inbodyShape: PVCoordinatesProvider

a copy of the detector.
