the start date

getEndDate

public AbsoluteDate getEndDate()

Get the end date.

Returns:

the end date

getDuration

public double getDuration()

Get the duration of the maneuver (s). duration = endDate - startDate

Returns:

the duration of the maneuver (s)

init

public void init(SpacecraftState initialState,
                 AbsoluteDate target)

Initialization method. Called in when Maneuver.init(...) is called (from ForceModel.init(...)).

Specified by:

init in interface ManeuverTriggers

Parameters:

initialState - initial spacecraft state (at the start of propagation).

target - date of propagation. Not equal to initialState.getDate().

getEventsDetectors

public Stream<EventDetector> getEventsDetectors()

Get the event detectors associated with the triggers.

Specified by:

getEventsDetectors in interface ManeuverTriggers

Returns:

the event detectors

getFieldEventsDetectors

public <T extends RealFieldElement<T>> Stream<FieldEventDetector<T>> getFieldEventsDetectors(Field<T> field)

Get the event detectors associated with the triggers.

Specified by:

getFieldEventsDetectors in interface ManeuverTriggers

Type Parameters:

T - extends RealFieldElement<T>

Parameters:

field - field to which the state belongs

Returns:

the event detectors

isFiring

public boolean isFiring(AbsoluteDate date,
                        double[] parameters)

Find out if the maneuver is firing or not.

Specified by:

isFiring in interface ManeuverTriggers

Parameters:

date - current date

parameters - maneuver triggers parameters

Returns:

true if the maneuver is firing, false otherwise

isFiring

public <T extends RealFieldElement<T>> boolean isFiring(FieldAbsoluteDate<T> date,
                                                        T[] parameters)

Description copied from interface: ManeuverTriggers

Find out if the maneuver is firing or not.

Specified by:

isFiring in interface ManeuverTriggers

Type Parameters:

T - extends RealFieldElement<T>

Parameters:

date - current date

parameters - maneuver triggers parameters

Returns:

true if the maneuver is firing, false otherwise

isFiring

public boolean isFiring(AbsoluteDate date)

Check if maneuvering is on.

Parameters:

date - current date
