Constructor Detail

FrameFacade

public FrameFacade(Frame frame,
                   CelestialBodyFrame celestialBodyFrame,
                   OrbitRelativeFrame orbitRelativeFrame,
                   SpacecraftBodyFrame spacecraftBodyFrame,
                   String name)

Simple constructor.

At most one of celestialBodyFrame, orbitRelativeFrame or spacecraftBodyFrame may be non null. They may all be null if frame is unknown, in which case only the name will be available.

Parameters:

frame - reference to node in Orekit frames tree (may be null)

celestialBodyFrame - reference to celestial body centered frame (may be null)

orbitRelativeFrame - reference to orbit-relative frame (may be null)

spacecraftBodyFrame - reference to spacecraft body frame (may be null)

name - name of the frame

Method Detail

asFrame

public Frame asFrame()

Get the associated frame tree node.

Returns:

associated frame tree node, or null if none exists

asCelestialBodyFrame

public CelestialBodyFrame asCelestialBodyFrame()

Get the associated celestial body frame.

Returns:

associated celestial body frame, or null if frame is associated to a orbit, a spacecraft or is not supported

asOrbitRelativeFrame

public OrbitRelativeFrame asOrbitRelativeFrame()

Get the associated orbit relative frame.

Returns:

associated orbit relative frame, or null if frame is associated to a celestial body, a spacecraft or is not supported

asSpacecraftBodyFrame

public SpacecraftBodyFrame asSpacecraftBodyFrame()

Get the associated spacecraft body frame.

Returns:

associated spacecraft body frame, or null if frame is associated to a celestial body, an orbit or is not supported

getName

public String getName()

Get the CCSDS name for the frame.

Returns:

CCSDS name

map

public static FrameFacade map(Frame frame)

Map an Orekit frame to a CCSDS frame facade.

Parameters:

frame - a reference frame.

Returns:

the CCSDSFrame corresponding to the Orekit frame

parse

public static FrameFacade parse(String name,
                                IERSConventions conventions,
                                boolean simpleEOP,
                                DataContext dataContext,
                                boolean allowCelestial,
                                boolean allowOrbit,
                                boolean allowSpacecraft)

Simple constructor.

Parameters:

name - name of the frame

conventions - IERS conventions to use

simpleEOP - if true, tidal effects are ignored when interpolating EOP

dataContext - to use when creating the frame

allowCelestial - if true, CelestialBodyFrame are allowed

allowOrbit - if true, OrbitRelativeFrame are allowed

allowSpacecraft - if true, SpacecraftBodyFrame are allowed

Returns:

frame facade corresponding to the CCSDS name
