Constructor Details

AbstractRelativeManeuver

public AbstractRelativeManeuver(EventDetector trigger,
 Vector3D deltaV,
 P relativeProvider)

Creates a new AbstractRelativeManeuver from an event detector, a ΔV vector, and a RelativeProvider.

Parameters:

trigger - Triggering event detector.

deltaV - ΔV vector in the local orbital frame of the theory used by the given RelativeProvider.

relativeProvider - Relative motion equations provider.

Method Details

init

public void init(SpacecraftState s0,
 AbsoluteDate t)

Initialize event detector at the start of a propagation.

This method is called once at the start of the propagation. It may be used by the event handler to initialize some internal data if needed.

The default implementation initializes the handler.

Specified by:

init in interface DetectorModifier

Specified by:

init in interface EventDetector

Parameters:

s0 - initial state

t - target time for the integration

getDetector

public EventDetector getDetector()

Get the wrapped detector.

Specified by:

getDetector in interface DetectorModifier

Returns:

wrapped detector

getHandler

public EventHandler getHandler()

Get the handler.

Specified by:

getHandler in interface DetectorModifier

Specified by:

getHandler in interface EventDetector

Returns:

event handler to call at event occurrences

toString

@DefaultDataContext
public String toString()

String representation in UTC.

Overrides:

toString in class Object

Returns:

string representation with date in UTC timescale

toString

public String toString(TimeScale timeScale)

String representation with timescale.

Parameters:

timeScale - timescale to use for date formatting

Returns:

string representation with timescale

getForward

public boolean getForward()

Getter for the forward boolean.

Returns:

forward boolean.

getDeltaV

public Vector3D getDeltaV()

Getter for the ΔV vector of the maneuver.

Specified by:

getDeltaV in interface RelativeManeuver

Returns:

The ΔV vector of the maneuver, expressed in the target spacecraft's LOF.

getRelativeProvider

public P getRelativeProvider()

Getter for the relative provider.

Specified by:

getRelativeProvider in interface RelativeManeuver

Returns:

relative motion provider.
