EarthCentralBody Properties |
The EarthCentralBody type exposes the following members.
Properties| Name | Description | |
|---|---|---|
 | CenterOfMassPoint |
Gets or sets a point describing the center of mass of this central body.
(Overrides CentralBodyCenterOfMassPoint.) |
| EquationOfEquinoxes |
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.
|
| FixedFrame |
Gets or sets the default Fixed frame that corresponds to the surface features of this central body.
(Overrides CentralBodyFixedFrame.) |
| InertialFrame |
Gets or sets the default Inertial frame for this central body.
(Overrides CentralBodyInertialFrame.) |
| InternationalCelestialReferenceFrame |
Gets or sets the International Celestial Reference Frame.
|
| IsFrozen |
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.
(Inherited from DefinitionalObject.) |
| IsThreadSafe |
Gets a value indicating whether the methods on this instance are safe to call from
multiple threads simultaneously.
(Inherited from CentralBody.) |
| J2000Frame |
Gets or sets the J2000 Reference Frame.
|
| MeanEclipticMeanEquinoxFrame |
Gets or sets the Mean Ecliptic Mean Equinox Reference Frame.
|
| MeanEclipticTrueEquinoxFrame |
Gets or sets the Mean Ecliptic True Equinox Reference Frame.
|
| MeanEquatorMeanEquinoxFrame |
Gets or sets the Mean Equator Mean Equinox Reference Frame, also
known as the "Mean of Date" reference frame.
|
 | MeanSeaLevel |
Gets or sets the default mean sea level surface.
|
| NaifIdCode | Gets the NAIF identification code of this central body, barycenter, spacecraft, ground station, or other physical object or location. A directory of NAIF IDs associated with commonly used Solar System bodies is available at the NAIF website. |
| Name |
Gets or sets the name of the central body.
(Overrides CentralBodyName.) |
| NutationModel |
Gets or sets the default nutation model used in the FK5 transformation from
J2000 to the Fixed frame. By default, this is Updated1980NutationModel.
|
| OrientationParameters |
Gets or sets the default EarthOrientationParameters.
|
| PrecessionModel |
Gets or sets the default precession model used in the FK5 transformation from
J2000 to the Fixed frame.
|
| PrincipalFrame |
Gets or sets the default Fixed frame that corresponds to the gravity frame of this central body.
(Overrides CentralBodyPrincipalFrame.) |
| PseudoFixedFrame |
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.
|
| Shape |
Gets or sets the shape of this central body.
(Overrides CentralBodyShape.) |
| SlowChangingAxesUpdateInterval |
Gets or sets the interval, in seconds, on which to recalculate slow-changing relationships between axes.
|
| TrueEquatorMeanEquinoxFrame |
Gets or sets the True Equator, Mean Equinox (TEME) Reference Frame.
|
| TrueEquatorTrueEquinoxFrame |
Gets or sets the True Equator True Equinox Reference Frame, also
known as the "True of Date" reference frame.
