Class PVCoordinatePropagator

java.lang.Object
  org.orekit.propagation.AbstractPropagator
      fr.cnes.sirius.patrius.propagation.PVCoordinatePropagator

All Implemented Interfaces:

Serializable, Propagator, PVCoordinatesProvider

public class PVCoordinatePropagator
extends AbstractPropagator

This class is an analytical propagator which propagates states from the input PV, Attitude, and additional state provider.

It can handle events and all functionalities from extended AbstractPropagator class.

Warning: Events detector with EventDetector.Action.RESET_STATE should not be used with this propagator fed with a "precomputed" PV coordinate provider (such as an ephemeris or an orbit object). In particular, impulse maneuvers cannot be used. Otherwise propagation will fail. This is due to the fact that the provided PV coordinate provider is not valid any more after the EventDetector.Action.RESET_STATE action.

                              Frame frame)
                       throws OrekitException

Creates an instance of PVCoordinatePropagator without attitude and additional state providers

Parameters:

pvCoordProvider - The position velocity coordinate provider used to propagate position velocity

initDate - reference date

mu - used for internal orbit parameter to convert orbital parameters type

frame - used to express the pv coordinates
