Constructor Detail

FieldExtremumAngularSeparationDetector

public FieldExtremumAngularSeparationDetector(FieldEventDetectionSettings<T> detectionSettings,
                                              FieldEventHandler<T> handler,
                                              ExtendedPositionProvider beacon,
                                              ExtendedPositionProvider observer)

Protected constructor with full parameters.

Parameters:

detectionSettings - detection settings

handler - event handler to call at event occurrences

beacon - beacon at the center of the proximity zone

observer - observer for the spacecraft, that may also see the beacon at the same time if they are too close to each other

Method Detail

create

protected FieldExtremumAngularSeparationDetector<T> create(FieldEventDetectionSettings<T> detectionSettings,
                                                           FieldEventHandler<T> newHandler)

Build a new instance.

Specified by:

create in class FieldAbstractDetector<FieldExtremumAngularSeparationDetector<T extends CalculusFieldElement<T>>,T extends CalculusFieldElement<T>>

Parameters:

detectionSettings - detection settings

newHandler - event handler to call at event occurrences

Returns:

a new instance of the appropriate sub-type

getBeacon

public ExtendedPositionProvider getBeacon()

Get the beacon at the center of the proximity zone.

Returns:

beacon at the center of the proximity zone

getObserver

public ExtendedPositionProvider getObserver()

Get the observer for the spacecraft.

Returns:

observer for the spacecraft

g

public T g(FieldSpacecraftState<T> s)

Description copied from interface: FieldEventDetector

Compute the value of the switching function. This function must be continuous (at least in its roots neighborhood), as the integrator will need to find its roots to locate the events.

Parameters:

s - the current state information: date, kinematics, attitude

Returns:

value of the switching function
