Interface ForceModelWithJacobians

All Superinterfaces:

ForceModel, Parameterizable, java.io.Serializable

All Known Implementing Classes:

DragForce, SolarRadiationPressure

public interface ForceModelWithJacobians
extends Parameterizable, ForceModel

This interface represents a parameterized force modifying spacecraft motion.

Objects implementing this interface are intended to be added, before the propagation is started, to a numerical propagator in order to compute partial derivatives of orbital parameters with respect to the selected force model parameters.
