All Implemented Interfaces:

Serializable, BoundedPropagator, Propagator, PVCoordinatesProvider

Deprecated.

@Deprecated
public class HermiteEphemeris
extends AbstractEphemeris

This class handles tabulated spacecraft states entries (either from a pv coordinates provider and an attitude provider or a spacecraft states array). Tabulated entries are chronologically ordered. Within the interval of validity, interpolation is performed in order to obtain continuous output. A Hermite interpolation is perfomed.

A Hermite interpolation is perfomed for PV coordinates

A Hermite interpolation is performed for quaternions

A linear interpolation is perfomed for additional states Important note : the validity interval of the extrapolated points is the same than the time interval, because the Hermite interpolation requires only 2 points.

This class is deprecated since 3.1 : use the new class EphemerisPvHermite

Since:

2.3

Constructor Detail

HermiteEphemeris

public HermiteEphemeris(PVCoordinatesProvider pvProv,
                        AttitudeProvider attProvForces,
                        AttitudeProvider attProvEvents,
                        double step,
                        AbsoluteDateInterval intervalOfPoints,
                        Frame frame2,
                        double mu2)
                 throws OrekitException

Deprecated.

Constructor n°1 using a PV coordinates provider and an AttitudeProvider to build the interpolation points.

Parameters:

pvProv - pv coordinates provider

attProvForces - attitude provider for forces computation

attProvEvents - attitude provider for events computation

step - step between two points

intervalOfPoints - points generation interval (larger than the extrapolations validity interval)

frame2 - reference frame

mu2 - mu

Throws:

OrekitException - herited from AbstractEphemeris or if the spacecraft states do not contain the same additional states if default attitude cannot be computed (when attProv is null)

HermiteEphemeris

public HermiteEphemeris(SpacecraftState[] tabStates,
                        Vector3D[] tabAcc)
                 throws OrekitException

Deprecated.

Constructor of class HermiteEphemeris, where a search index algorithm is passed on the constructor. Creates a search index algorithm by default as a BinarySearchIndexOpenClosed.

Parameters:

tabStates - : an array of SpacecraftState chronologically sorted. If not, returned result may be wrong (no exception will be thrown).

tabAcc - array of accelerations, a different polynomial for interpolation is used (degree 5)

Throws:

OrekitException - herited from AbstractEphemeris or OrekitMessages.INVALID_ARRAY_LENGTH if tabulatedStates and tabulatedAcc do not have the same length

HermiteEphemeris

public HermiteEphemeris(SpacecraftState[] tab)
                 throws OrekitException

Deprecated.

Constructor of class HermiteEphemeris, used by other constructors of this class. Inherit from AbstractEphemeris. Creates a search index algorithm by default as a BinarySearchIndexOpenClosed.

Parameters:

Throws:

OrekitException - OrekitMessages.NOT_ENOUGH_INTERPOLATION_POINTS if the tab is does not contains at least (order) points

Method Detail

getInterpolatedSpacecraftState

protected SpacecraftState getInterpolatedSpacecraftState(AbsoluteDate date)

Deprecated.

Get the interpolated spacecraft state.

WARNING: when implementing this method. a call to AbstractEphemeris.checkBounds(double) should be performed first to properly handle date on bounds since none of search index convention are able to properly handle both bounds.

Specified by:

getInterpolatedSpacecraftState in class AbstractEphemeris

Parameters:

date - interpolation date

Returns:

interpolated spacecraft state

Throws:

OrekitException - thrown if input date is out of the interval validity.
