IersTechnicalNote36RelativisticCorrectionForceCentralBodyAngularMomentumPerUnitMass Property

Gets or sets a vector that describes the angular momentum per unit mass of the CentralBody. This vector is used for the Lense-Thirring correction, and may be safely ignored if this term is not used. Two easy-to-use static helper methods for this vector exist on this class; RouthsRuleAngularMomentumPerUnitMass(CentralBody) and ScaledAngularVelocityAngularMomentumPerUnitMass(CentralBody, Double).

Namespace:  AGI.Foundation.Celestial

public Vector CentralBodyAngularMomentumPerUnitMass { get; set; }

Property Value

Type: Vector
One way to get this vector easily is to use VectorAngularVelocity with the axes of the fixed frame of the central body used as the rotating axes, and the axes of the solar system barycenter's inertial frame used as the reference axes. This angular velocity vector can then be fed into a VectorScaled using Routh's rule for an ellipsoid, less the mass term, as the scale factor to obtain the desired vector.
