Constructor Detail

AbstractJPLCelestialBodyLoader

public AbstractJPLCelestialBodyLoader(String supportedNamesIn,
                                      JPLEphemerisLoader ephemerisLoader)

Create a loader for JPL ephemerides binary files (DE-INPOP type).

Parameters:

supportedNamesIn - regular expression for supported files names

ephemerisLoader - ephemeris loader

Method Detail

getLoadedGravitationalCoefficient

public double getLoadedGravitationalCoefficient(PredefinedEphemerisType body)
                                         throws PatriusException

Get the gravitational coefficient of a body.

Parameters:

body - body for which the gravitational coefficient is requested

Returns:

gravitational coefficient in m³/s²

Throws:

PatriusException - if constants cannot be loaded

buildDefaultBodyShape

protected BodyShape buildDefaultBodyShape(String name,
                                          CelestialBodyFrame bodyFrame,
                                          PredefinedEphemerisType ephemerisType)

Builds a OneAxisEllipsoid as a default shape for the loaded celestial body. In the case the celestial body is not physically defined, typically the case for barycenters, the default shape returned is a null shape.

Parameters:

name - the body name

bodyFrame - parent frame (usually it should be the ICRF centered on the parent body)

ephemerisType - ephemeris type

Returns:

the shape of the celestial body

getEphemerisLoader

public JPLEphemerisLoader getEphemerisLoader()

Returns the ephemeris loader.

Returns:

the ephemeris loader

getSupportedNames

public String getSupportedNames()

Returns the supported file names.

Returns:

the supported file names
