Syntax
public sealed class GravityGradientTorque : TorqueModel

The GravityGradientTorque type exposes the following members.

Constructors
  NameDescription
Public methodGravityGradientTorque(Point, Matrix3By3Symmetric, Axes)
Initializes the gravity-gradient torque model. By default the CentralBody is set to Earth from the CentralBodiesFacet and the GravitationalParameter is set to GravitationalParameter.
Public methodGravityGradientTorque(Point, CentralBody, Double, Matrix3By3Symmetric, Axes)
Initializes the gravity-gradient torque model.

Properties
  NameDescription
Public propertyBodyAxes
Gets or sets the body axes of the gravity-gradient satellite. These should be the IntegrationAxes of the PropagationEulerianAxes associated with the gravity-gradient satellite.
Public propertyBodyCenterOfMass
Gets or sets the center of mass point of the gravity-gradient satellite.
Public propertyCentralBody
Gets or sets the body which creates the gravity and provides a reference point at its center of mass.
Public propertyGravitationalParameter
Gets or sets the gravitational parameter to use when computing gravity, in meters cubed per second squared.
Public propertyInertiaMatrix
Gets or sets the 3x3 inertia matrix of the gravity-gradient satellite. This must be defined in the BodyAxes.
Public propertyIsFrozen
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.)
Public propertyTorqueVector
Gets the Vector representation of this torque.
(Inherited from TorqueModel.)

Methods
  NameDescription
Public methodBuildTorqueEvaluator
Build lists of torques based on this model in order to create an overall resultant torque.
(Overrides TorqueModelBuildTorqueEvaluator(ResultantTorqueBuilder, EvaluatorGroup).)
Public methodClone
Clones this object using the specified context.
(Overrides DefinitionalObjectClone(CopyContext).)
Public methodEnumerateDependencies
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.
(Overrides TorqueModelEnumerateDependencies(DependencyEnumerator).)
Public methodEquals
Determines whether the specified object is equal to the current object.
(Inherited from Object.)
Public methodFreeze
Freezes this object. Further attempts to modify it will result in an ObjectFrozenException.
(Inherited from DefinitionalObject.)
Public methodGetDefinitionHashCode
Gets a hash code representing the definition of this object.
(Inherited from DefinitionalObject.)
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
Public methodGetTorqueEvaluator
Gets an instance of an evaluator that can compute the torque.
(Inherited from TorqueModel.)
Public methodGetTorqueEvaluator(EvaluatorGroup)
Gets an instance of an evaluator that can compute the torque.
(Overrides TorqueModelGetTorqueEvaluator(EvaluatorGroup).)
Public methodGetType
Gets the Type of the current instance.
(Inherited from Object.)
Public methodIsSameDefinition
Determines if this object has the same definition as another object.
(Inherited from DefinitionalObject.)
Public methodToString
Returns a string that represents the current object.
(Inherited from Object.)

Remarks
It is assumed that there are no inertia terms that are higher order than the moment of inertia matrix and that there are no gravity terms higher than the point-mass gravity term.
