public interface StelaForceModel
extends Serializable

This interface represents a force modifying spacecraft motion for a StelaGTOPropagator.

Objects implementing this interface are intended to be added to a semianalytical Stela GTO propagator before the propagation is started.

Method Detail

computeShortPeriods

double[] computeShortPeriods(StelaEquinoctialOrbit orbit,
                             OrbitNatureConverter converter)
                      throws PatriusException

Compute the short periodic variations for a given spacecraft state.

Parameters:

orbit - current orbit information: date, kinematics

converter - converter necessary in some specific case (drag short periods computation)

Returns:

the short periodic variations of the current force

Throws:

PatriusException - if short periods computation fails

computePartialDerivatives

double[][] computePartialDerivatives(StelaEquinoctialOrbit orbit)
                              throws PatriusException

Compute the partial derivatives for a given spacecraft state.

Parameters:

orbit - current orbit information: date, kinematics

Returns:

the partial derivatives of the current force

Throws:

PatriusException - if partial derivatives computation fails

getType

String getType()

Returns:

the type
