The Covariance6By6TwoBodyBlender type exposes the following members.

Constructors
  NameDescription
Public methodCovariance6By6TwoBodyBlender(DateMotionCollectionCartesian, DateMotionCollectionMatrix)
Initializes a new instance. By default, the OrbitStatesFrame and InertialPropagationFrame are set to the inertial frame of the instance of EarthCentralBody in the CentralBodiesFacet of the CalculationContext. Similarly, the CovarianceAxes are set to the Axes of that inertial frame. The GravitationalParameter is set to that of the WorldGeodeticSystem1984. to the
Public methodCovariance6By6TwoBodyBlender(DateMotionCollectionCartesian, IDateMotionCollectionMatrix6By6Symmetric)
Initializes a new instance. By default, the OrbitStatesFrame and InertialPropagationFrame are set to the inertial frame of the instance of EarthCentralBody in the CentralBodiesFacet of the CalculationContext. Similarly, the CovarianceAxes are set to the Axes of that inertial frame. The GravitationalParameter is set to that of the WorldGeodeticSystem1984.

Properties
  NameDescription
Public propertyCovarianceAxes
Gets or sets the native axes of the CovarianceData.
Public propertyCovarianceData
Gets or sets the covariance data that is used for blending.
Public propertyDateTolerance
Gets or sets the tolerance in seconds that is used to ensure that the dates in OrbitStates and CovarianceData are close enough to being equal. By default, this value is Epsilon6.
Public propertyGravitationalParameter
Gets or sets the gravitational parameter of the central body that the spacecraft is orbiting.
Public propertyInertialPropagationFrame
Gets or sets the inertial propagation frame that is used to propagate the OrbitStates and the CovarianceData.
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 propertyOrbitStates
Gets or sets the position and velocity vectors of the spacecraft at the same times as the CovarianceData.
Public propertyOrbitStatesFrame
Gets or sets the native reference frame of the OrbitStates.

Methods
  NameDescription
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 DefinitionalObjectEnumerateDependencies(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 methodGetEvaluator
Gets an evaluator that blends the covariance information.
Public methodGetEvaluator(EvaluatorGroup)
Gets an evaluator that blends the covariance information.
Public methodGetHashCode
Serves as the default hash function.
(Inherited from Object.)
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.)
Public methodStatic memberTransformCovariance
Transforms a 6x6 covariance matrix into new axes.

Remarks

This should only be used in orbital regimes where two-body gravity is a reasonable first approximation.
