CelestialBody describes, besides the attributes of CelestialPoint, a GravityModel, an IAUPole and a BodyShape. The EMB and SSB objects are now built as CelestialPoint.<br /> * Add the Ecliptic_J2000 frame, accessible from FramesFactory.getEclipticJ2000(). Every CelestialPoint objects has a Ecliptic_J2000 frame defined in its center.<br /> * Add the G50 frame, accessible from FramesFactory.getG50().<br /> * A celestial body orientation can now be defined with quaternions. This evolution adds the interfaces CelestialBodyOrientation and CelestialBodyIAUOrientation (IAUPole renamed) and the class CelestialBodyTabulatedOrientation.<br /> * Add a generic filter method in the interface EventDetector (already applied for LocalTimeAngleDetector)<br /> * Merge the eclipse and lightning ratio computation between EclipseDetector and SolarRadiationPressure.<br /> * The obliquity and precession model of the Earth (used for the MOD reference frame) has been made configurable through the configuration of reference frames:<br /> ** Add the interface MODPrecessionModel and one implementation IAUMODPrecessionModel<br /> ** Add getters/setters in the frames configuration<br /> * Add the SurfaceDistanceDetector detector allowing to detect the distance at the surface of a celestial body (ellipsoid, facet body, etc).<br /> * Add the class ThreeAxisEllipsoid allowing to represent a 3-axis ellipsoid. This class extends EllipsoidBodyShape.<br /> * Add the DatePolynomialFunctionInterface#copy(AbsoluteDate newOriginDate) method, allowing to instanciate a new equivalent polynomial function at a different T0 date.<br /> * PotentialCoefficientsReader can now read gravity model sigmas<br /> * New SignalPropagationWrapperDetector allowing to wrap extisting compatible detectors and extract signal emitter and/or receiver dates associated to an event.<br /> * Add new methods in RealMatrix : double getMin(boolean absValue), double getMax(boolean absValue) and RealMatrix getAbs()<br /> * Add new matrix NUMPY_FORMAT format in MatrixUtils + new features<br /> * AngularCorrection extends IParameterizable<br /> * Standard parameters in MeteorologicalConditions are public + a STANDARD pre-build instance is accessible<br /> * FiniteDistanceAngularCorrection : new interface allows characterizing an angular correction when the distance between the observer and the target is finite (to account for parallax correction, for example).<br /> * AstronomicalRefractionModel : new class to represent a troposhere refraction model. The new AstronomicalRefractionModelFactory class facilitate its usage.<br /> * VacuumSignalPropagation : new getEmitterPV &amp; getReceiverPV methods + define the internal enumerate SignalPropagationRole to dissociate the role of transmitter or receiver.<br /> * IntervalMapSearcher : new class allowing to associate objects to date intervals with an optimized cache managment.<br /> * CardanCalculator : new class similar to AzimuthElevationCalculator, describing static computational methods for the Cardan angles.<br /> * ZernikePolynomial : new class to represent a Zernike polynomial<br /> * LightAberrationCorrection : new class replacing StellarAberrationCorrection<br /> <br /> <br /> == Bugs fixes ==<br /> * LongitudeDetector : the 2pi-&gt;0 jump is fixed<br /> * Existing informatic formats for matrix representation in MatrixUtils (JAVA, OCTAVE, SCILAB, NUMPY) now display all the digits<br /> * The use of BSP files for celestial bodies has been made more robust.<br /> * The PyramidalField union calculation is more robust in certain configurations.<br /> * &quot;FieldDescriptor: The printFunction parameter becomes serializable.</div>
