  - getFrame
```
public Frame getFrame(Predefined factoryKey)
```
    Description copied from interface: Frames
    
    Get one of the predefined frames.
    
    Specified by:
    
    getFrame in interface Frames
    
    Parameters:
    
    factoryKey - key of the frame within the factory
    
    Returns:
    
    the predefined frame
  - getGCRF
```
public Frame getGCRF()
```
    Description copied from interface: Frames
    
    Get the unique GCRF frame.
    The GCRF frame is the root frame in the frame tree.
    
    Specified by:
    
    getGCRF in interface Frames
    
    Returns:
    
    the unique instance of the GCRF frame
  - getICRF
```
public Frame getICRF()
```
    Description copied from interface: Frames
    
    Get the unique ICRF frame.
    The ICRF frame is centered at solar system barycenter and aligned with GCRF.
    
    Specified by:
    
    getICRF in interface Frames
    
    Returns:
    
    the unique instance of the ICRF frame
  - getEcliptic
```
public Frame getEcliptic(IERSConventions conventions)
```
    Description copied from interface: Frames
    
    Get the ecliptic frame. The IAU defines the ecliptic as "the plane perpendicular to the mean heliocentric orbital angular momentum vector of the Earth-Moon barycentre in the BCRS (IAU 2006 Resolution B1)." The +z axis is aligned with the angular momentum vector, and the +x axis is aligned with +x axis of MOD.
    This implementation agrees with the JPL 406 ephemerides to within 0.5 arc seconds.
    
    Specified by:
    
    getEcliptic in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    Returns:
    
    the selected reference frame singleton.
  - getEME2000
```
public FactoryManagedFrame getEME2000()
```
    Description copied from interface: Frames
    
    Get the unique EME2000 frame.
    The EME2000 frame is also called the J2000 frame. The former denomination is preferred in Orekit.
    
    Specified by:
    
    getEME2000 in interface Frames
    
    Returns:
    
    the unique instance of the EME2000 frame
  - getITRF
```
public FactoryManagedFrame getITRF(IERSConventions conventions,
                                   boolean simpleEOP)
```
    Description copied from interface: Frames
    
    Get an unspecified International Terrestrial Reference Frame.
    The frame returned uses the Earth Orientation Parameters blindly. So if for example one loads only EOP 14 C04 files to retrieve the parameters, the frame will be an ITRFVersion.ITRF_2014. However, if parameters are loaded from different files types, or even for file types that changed their reference (like Bulletin A switching from ITRFVersion.ITRF_2008 to ITRFVersion.ITRF_2014 starting with Vol. XXXI No. 013 published on 2018-03-29), then the ITRF returned by this method will jump from one version to another version.
    
    IF a specific version of ITRF is needed, then Frames.getITRF(ITRFVersion, IERSConventions, boolean) should be used instead.
    
    Specified by:
    
    getITRF in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    simpleEOP - if true, tidal effects are ignored when interpolating EOP
    
    Returns:
    
    the selected reference frame singleton.

public FactoryManagedFrame getTIRF(IERSConventions conventions)
```
    Description copied from interface: Frames
    
    Get the TIRF reference frame, ignoring tidal effects.
    
    Specified by:
    
    getTIRF in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    Returns:
    
    the selected reference frame singleton. library cannot be read.
  - getITRF
```
public VersionedITRF getITRF(ITRFVersion version,
                             IERSConventions conventions,

```
    Description copied from interface: Frames
    
    Get an specific International Terrestrial Reference Frame.
    Note that if a specific version of ITRF is required, then simpleEOP should most probably be set to false, as ignoring tidal effects has an effect of the same order of magnitude as the differences between the various ITRF versions.

    Specified by:
    
    getITRFEquinox in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    simpleEOP - if true, tidal effects are ignored when interpolating EOP
    
    Returns:

  - getGTOD
```
public FactoryManagedFrame getGTOD(boolean applyEOPCorr)
```
    Description copied from interface: Frames
    
    Get the GTOD reference frame.
    The applyEOPCorr parameter is available mainly for testing purposes or for consistency with legacy software that don't handle EOP correction parameters. Beware that setting this parameter to false leads to crude accuracy (order of magnitudes for errors might be above 250m in LEO and 1400m in GEO). For this reason, setting this parameter to false is restricted to IERS 1996 conventions, and hence the IERS conventions cannot be freely chosen here.
    
    Specified by:
    
    getGTOD in interface Frames
    
    Parameters:
    
    applyEOPCorr - if true, EOP corrections are applied (here, dut1 and lod)
    
    Returns:
    
    the selected reference frame singleton.
  - getGTOD
```
public FactoryManagedFrame getGTOD(IERSConventions conventions,
                                   boolean simpleEOP)
```
    Description copied from interface: Frames
    
    Get the GTOD reference frame.
    
    Specified by:
    
    getGTOD in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    simpleEOP - if true, tidal effects are ignored when interpolating EOP
    
    Returns:
    
    the selected reference frame singleton.
  - getTOD
```
public FactoryManagedFrame getTOD(boolean applyEOPCorr)
```
    Description copied from interface: Frames
    
    Get the TOD reference frame.
    The applyEOPCorr parameter is available mainly for testing purposes or for consistency with legacy software that don't handle EOP correction parameters. Beware that setting this parameter to false leads to crude accuracy (order of magnitudes for errors might be above 1m in LEO and 10m in GEO). For this reason, setting this parameter to false is restricted to IERS 1996 conventions, and hence the IERS conventions cannot be freely chosen here.
    
    Specified by:
    
    getTOD in interface Frames
    
    Parameters:
    
    applyEOPCorr - if true, EOP corrections are applied (here, nutation)
    
    Returns:
    
    the selected reference frame singleton.
  - getTOD
```
public FactoryManagedFrame getTOD(IERSConventions conventions,
                                  boolean simpleEOP)
```
    Description copied from interface: Frames
    
    Get the TOD reference frame.
    
    Specified by:
    
    getTOD in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    simpleEOP - if true, tidal effects are ignored when interpolating EOP
    
    Returns:
    
    the selected reference frame singleton.
  - getMOD
```
public FactoryManagedFrame getMOD(boolean applyEOPCorr)
```
    Description copied from interface: Frames
    
    Get the MOD reference frame.
    The applyEOPCorr parameter is available mainly for testing purposes or for consistency with legacy software that don't handle EOP correction parameters. Beware that setting this parameter to false leads to crude accuracy (order of magnitudes for errors might be above 1m in LEO and 10m in GEO). For this reason, setting this parameter to false is restricted to IERS 1996 conventions, and hence the IERS conventions cannot be freely chosen here.
    
    Specified by:
    
    getMOD in interface Frames
    
    Parameters:
    
    applyEOPCorr - if true, EOP corrections are applied (EME2000/GCRF bias compensation)
    
    Returns:
    
    the selected reference frame singleton.
  - getMOD
```
public FactoryManagedFrame getMOD(IERSConventions conventions)
```
    Description copied from interface: Frames
    
    Get the MOD reference frame.
    
    Specified by:
    
    getMOD in interface Frames
    
    Parameters:
    
    conventions - IERS conventions to apply
    
    Returns:
    
    the selected reference frame singleton.
  - getTEME
```
public FactoryManagedFrame getTEME()
```
    Description copied from interface: Frames
    
    Get the TEME reference frame.
    The TEME frame is used for the SGP4 model in TLE propagation. This frame has no official definition and there are some ambiguities about whether it should be used as "of date" or "of epoch". This frame should therefore be used only for TLE propagation and not for anything else, as recommended by the CCSDS Orbit Data Message blue book.
    
    Specified by:
    
    getTEME in interface Frames
    
    Returns:
    
    the selected reference frame singleton.
  - getPZ9011
```
public FactoryManagedFrame getPZ9011(IERSConventions convention,
                                     boolean simpleEOP)
```
    Description copied from interface: Frames
    Get the PZ-90.11 (Parametry Zemly – 1990.11) reference frame.
