public interface BasicPropagator
extends PVCoordinatesProvider, java.io.Serializable

This interface provides a way to propagate an orbit at any time.

This interface is the simplest abstraction for orbit propagation. It only allows propagation to a predefined date.

Method Detail

propagate

SpacecraftState propagate(AbsoluteDate target)
                          throws PropagationException

Propagate towards a target date.

Simple propagators use only the target date as the specification for computing the propagated state. More feature rich propagators like the ones implemented the extended interface Propagator can consider other information and provide different operating modes or G-stop facilities to stop at pinpointed events occurrences. In these cases, the target date is only a hint, not a mandatory objective.

Parameters:

target - target date towards which orbit state should be propagated

Returns:

propagated state

Throws:

PropagationException - if state cannot be propagated
