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.

orbit - current orbit information: date, kinematics

Returns:

the partial derivatives of the current force

Throws:

PatriusException - if partial derivatives computation fails

getType
