public class ClohessyWiltshireRendezVous
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.

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