The GravityGradientTorque type exposes the following members.

Constructors

	Name	Description
	GravityGradientTorque(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.
	GravityGradientTorque(Point, CentralBody, Double, Matrix3By3Symmetric, Axes)	Initializes the gravity-gradient torque model.

Properties

	Name	Description
	BodyAxes	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.
	BodyCenterOfMass	Gets or sets the center of mass point of the gravity-gradient satellite.
	CentralBody	Gets or sets the body which creates the gravity and provides a reference point at its center of mass.
	GravitationalParameter	Gets or sets the gravitational parameter to use when computing gravity, in meters cubed per second squared.
	InertiaMatrix	Gets or sets the 3x3 inertia matrix of the gravity-gradient satellite. This must be defined in the BodyAxes.
	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.)
	TorqueVector	Gets the Vector representation of this torque. (Inherited from TorqueModel.)

Methods

	Name	Description
	BuildTorqueEvaluator	Build lists of torques based on this model in order to create an overall resultant torque. (Overrides TorqueModelBuildTorqueEvaluator(ResultantTorqueBuilder, EvaluatorGroup).)
	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. (Overrides TorqueModelEnumerateDependencies(DependencyEnumerator).)
	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.)
	GetDefinitionHashCode	Gets a hash code representing the definition of this object. (Inherited from DefinitionalObject.)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	GetTorqueEvaluator	Gets an instance of an evaluator that can compute the torque. (Inherited from TorqueModel.)
	GetTorqueEvaluator(EvaluatorGroup)	Gets an instance of an evaluator that can compute the torque. (Overrides TorqueModelGetTorqueEvaluator(EvaluatorGroup).)
	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.)

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.
