org.orekit.propagation.relative.yamanakaankersen.FieldYamanakaAnkersenRendezVous<T>

Type Parameters:

T - Any scalar field.

public class FieldYamanakaAnkersenRendezVous<T extends CalculusFieldElement<T>>
extends Object

This class implements the solution to the Yamanaka-Ankersen equations for a two-impulse rendez-vous as presented in the Ankersen thesis. Ref : "Guidance, Navigation, Control and Relative Dynamics for Spacecraft Proximity Maneuvers",Ph .D Thesis, Finn Ankersen, 2010, see Chapter 4.6 Local Orbital Frame for use of Yamanaka-Ankersen Equations is LVLH CCSDS.

For more general rendez-vous transfer orbit computations, see IodLambert.

Method Details

computeRendezVous

public FieldTwoImpulseTransfer<T> computeRendezVous(TimeStampedFieldPVCoordinates<T> chaserPVTInitial,
 TimeStampedFieldPVCoordinates<T> chaserPVTFinal,
 Frame chaserPVFrame,
 FieldOrbit<T> targetOrbit,
 FieldPropagator<T> propagator)

Computes a two-impulse transfer between an initial and final positions using the Yamanaka-Ankersen closed-form solution.

Parameters:

chaserPVTInitial - Initial chaser PVT expressed in provided frame.

chaserPVTFinal - Final chaser PVT expressed in provided frame.

chaserPVFrame - Frame in which the initial and final chaser PVT are expressed.

targetOrbit - Target spacecraft's orbit.

propagator - Propagator used to compute the final state of the target to get the final True Anomaly.

Returns:

TwoImpulseTransfer
