org.orekit.propagation.relative.clohessywiltshire.FieldClohessyWiltshireRendezVous<T>

Type Parameters:

T - Any scalar field.

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

This class implements the solution to the Clohessy-Wiltshire equations for a two-impulse rendez-vous. The Clohessy-Wiltshire equations have a closed-form solution which enables extremely fast rendez-vous computations for circular target orbits, as long as the chaser is not too far from the target.

Method Details

computeRendezVous

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

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

Unlike its non-field, this method cannot be static because of the genericity introduced by the field. The field type T cannot be inferred from the method parameters, and must be defined at the class level.

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

Returns:

TwoImpulseTransfer to perform the rendezvous
