public class PartialDerivativesEquations
extends AbstractPartialDerivativesEquations

Set of additional equations computing the partial derivatives of the state (orbit) with respect to initial state and force models parameters.

This set of equations are automatically added to a numerical propagator in order to compute partial derivatives of the orbit along with the orbit itself. This is useful for example in orbit determination applications.

Constructor Detail

PartialDerivativesEquations

public PartialDerivativesEquations()

Empty constructor for Externalizable use.

PartialDerivativesEquations

public PartialDerivativesEquations(String nameIn,
                                   NumericalPropagator propagatorIn)

Simple constructor.

Upon construction, this set of equations is automatically added to the propagator by calling its NumericalPropagator.addAdditionalEquations(AdditionalEquations) method. So there is no need to call this method explicitly for these equations.

Parameters:

nameIn - name of the partial derivatives equations

propagatorIn - the propagator that will handle the orbit propagation
