PermanentSolidTideModel Class 
Namespace: AGI.Foundation.Celestial
The PermanentSolidTideModel type exposes the following members.
Name  Description  

PermanentSolidTideModel 
Constructs a default Earthcentered tide model that adds the Earth's permanent tide C20 value that was determined by the
International Earth Rotation and Reference Systems Service (IERS) in their IERS Conventions (2003) Technical Note No. 32.
 
PermanentSolidTideModel(CentralBody, Double, Double, Double, Double, Double, Double, Double) 
Constructs a generic permanent tide model that is degree and order 2 that can be used for any central body,
but needs to be used for bodies other than Earth.

Name  Description  

CentralBody 
Gets or sets the primary gravitational body.
(Inherited from SolidTideModel.)  
GravitationalParameter 
Gets or sets the gravitational parameter of the primary gravitational body.
(Inherited from SolidTideModel.)  
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.)  
PermanentCosineTideCoefficients 
Gets the twodimensional array of the permanent cosine tide coefficients.
 
PermanentSineTideCoefficients 
Gets the twodimensional array of the permanent sine tide coefficients.
 
PermanentZonalTideCoefficients 
Gets the onedimensional array of the permanent zonal tide coefficients.
 
ReferenceDistance 
Gets or sets the reference distance associated with the solid tide model (which is usually the equatorial radius of the primary gravitational body).
(Inherited from SolidTideModel.)  
TideCoefficientsDegree 
Gets or sets the degree of the tidal spherical harmonic gravity field.
(Inherited from SolidTideModel.)  
TideCoefficientsOrder 
Gets or sets the order of the tidal spherical harmonic gravity field.
(Inherited from SolidTideModel.) 
Name  Description  

Clone 
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).)  
EnumerateDependencies 
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.
(Inherited from SolidTideModel.)  
Equals  Determines whether the specified object is equal to the current object. (Inherited from Object.)  
Freeze 
Freezes this object. Further attempts to modify it will result
in an ObjectFrozenException.
(Inherited from DefinitionalObject.)  
GetCoefficientsEvaluator 
Gets an instance of an evaluator that returns the normalized tide coefficients of the solid tide model at a given time.
(Inherited from SolidTideModel.)  
GetCoefficientsEvaluator(EvaluatorGroup) 
Gets an instance of an evaluator that returns the normalized tide coefficients of the solid tide model.
For permanent tides, the tide coefficients are timeinvariant.
(Overrides SolidTideModelGetCoefficientsEvaluator(EvaluatorGroup).)  
GetDefinitionHashCode 
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)  
GetHashCode  Serves as the default hash function. (Inherited from Object.)  
GetType  Gets the Type of the current instance. (Inherited from Object.)  
IsSameDefinition 
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)  
ToString  Returns a string that represents the current object. (Inherited from Object.) 
The term "tidefree model" implies that the spherical harmonic gravity model assumes that tidal forces of third bodies do not affect a central body's gravity field at all. In terms of .grv files, a spherical harmonic gravity model that does not include permanent tides is a "tidefree model".
The term "zerotide model" implies that the spherical harmonic gravity model averages the effects of the tidal forces of third bodies over time to avoid having to implement timevarying solid tides. In terms of .grv files, a spherical harmonic gravity model that includes permanent tides is a "zerotide model".
