EarthCentralBody Class

Initializes a new instance.

Initializes a new instance as a copy of an existing instance.

Gets or sets a point describing the center of mass of this central body.

Gets or sets the default model for the equation of the equinoxes which defines the right ascension of the mean equinox with respect to the true equator and equinox. By default, this uses the UpdatedEquationOfEquinoxes.

Gets or sets the default Fixed frame that corresponds to the surface features of this central body.

Gets or sets the default Inertial frame for this central body.

Gets or sets the International Celestial Reference Frame.

Gets a value indicating whether this object is frozen. A frozen object cannot be modified and an ObjectFrozenException will be thrown if an attempt is made to do so.

Gets a value indicating whether the methods on this instance are safe to call from multiple threads simultaneously.

Gets or sets the J2000 Reference Frame.

Gets or sets the Mean Ecliptic Mean Equinox Reference Frame.

Gets or sets the Mean Ecliptic True Equinox Reference Frame.

Gets or sets the Mean Equator Mean Equinox Reference Frame, also known as the "Mean of Date" reference frame.

Gets or sets the default mean sea level surface.

Gets or sets the name of the central body.

Gets or sets the default nutation model used in the FK5 transformation from J2000 to the Fixed frame. By default, this is Updated1980NutationModel.

Gets or sets the default EarthOrientationParameters.

Gets or sets the default precession model used in the FK5 transformation from J2000 to the Fixed frame.

Gets or sets the default Fixed frame that corresponds to the gravity frame of this central body.

Gets or sets the pseudo-fixed reference frame. The pseudo-fixed frame does not include the effect of pole wander. Note that this does include the s-prime correction from the International Celestial Reference System. So the only difference between the pseudo-fixed frame and the fixed frame is the 'x' and 'y' offset terms from pole wander computed by the EarthOrientationParameters (EOP). If the EOP data is default (zeros), the pseudo-fixed frame will be the same as the FixedFrame.

Gets or sets the shape of this central body.

Gets or sets the interval, in seconds, on which to recalculate slow-changing relationships between axes.

Gets or sets the True Equator, Mean Equinox (TEME) Reference Frame.

Gets or sets the True Equator True Equinox Reference Frame, also known as the "True of Date" reference frame.

Checks to determine if another instance has the same definition as this instance and returns if it does. Derived classes MUST override this method and check all new fields introduced by the derived class for definitional equivalence. It is NOT necessary to check base class fields because the base class will already have done that. When overriding this method, you should NOT call the base implementation because it will return for all derived-class instances. Derived classes should check the type of other to preserve the symmetric nature of IsSameDefinition(Object).

Clones this object using the specified context.

Computes a hash code based on the current properties of this object. Derived classes MUST override this method and compute a hash code that combines: a unique hash code seed, the base implementation result, and the hash codes of all new fields introduced by the derived class which are used in the CheckForSameDefinition(DefinitionalObject) method.

Enumerates the dependencies of this object by calling EnumerateT(T) for each object that this object directly depends upon. Derived classes which contain additional dependencies MUST override this method, call the base implementation, and enumerate dependencies introduced by the derived class.

Determines whether the specified object is equal to the current object.

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.

Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.

Called by Freeze to also freeze any objects that are considered to be a part of this object. Derived classes which contain additional aggregated objects MUST override this method, call the base implementation, and freeze aggregated objects introduced by the derived class. The objects that need to be frozen in this method are frequently created in this object's constructor and are not settable via properties.

Gets an evaluator to find the azimuth, elevation, and range of a displacement vector as observed from the initial point.

Gets an evaluator to find the azimuth, elevation, and range of a vector as observed from a given point.

Gets an evaluator to find the azimuth, elevation, and range of a displacement vector as observed from the initial point, and associates the evaluator with the specified evaluator group.

Gets an evaluator to find the azimuth, elevation, and range of a vector as observed from a given point, and associates the evaluator with the specified evaluator group.

Gets a hash code representing the definition of this object.

Serves as the default hash function.

Gets the service object of the specified type.

Gets the Type of the current instance.

Determines if this object has the same definition as another object.

Creates a shallow copy of the current Object.

Gets an evaluator that can be used to find the Cartographic motion of a point relative to this central body.

Gets an evaluator that can be used to find the Cartographic motion of a point relative to this central body.

Sets the Origin of the InertialFrame, J2000Frame, InternationalCelestialReferenceFrame, FixedFrame, PrincipalFrame, PseudoFixedFrame, MeanEquatorMeanEquinoxFrame, MeanEclipticMeanEquinoxFrame, MeanEclipticTrueEquinoxFrame, TrueEquatorTrueEquinoxFrame, and TrueEquatorMeanEquinoxFrame to the current CenterOfMassPoint.

Throws ObjectFrozenException if this object IsFrozen. This method should be called from any method or property that modifies this object.

Returns a string that represents the current object.
