Package org.orekit.propagation.relative.clohessywiltshire

package org.orekit.propagation.relative.clohessywiltshire

This package provides an implementation of the equations of Clohessy and Wiltshire.

Hill-Clohessy-Wiltshire equations are analytical equations for describing the relative motion of a chaser spacecraft in regard to a target spacecraft when the target is on a circular orbit. These equations are only valid under the assumption of Keplerian dynamics.

In this package:

• ClohessyWiltshireProvider implements AdditionalDataProvider to propagate the chaser state together with the target state as an AdditionalData.
• ClohessyWilthireRendezVous computes a TwoImpulseTransfer to realize a rendezvous with the target in a chosen duration.
