Description

This attitude guidance module computes the orbital Hill reference frame states. The orbit can be any type of Keplerian motion, including circular, elliptical or hyperbolic. This is also known as Hill Pointing software. The LVLH coordinate system is defined by the unit vectors {i_r, i_theta, i_h}, with radial vector i_r, angular momentum vector i_h = r^ x v^, and azimuthal vector i_theta to complete the triad.

Methods

Inherited	Description
Destroy	Removes the current object from the simulation.
Disable	Disable the software componentDerived classes should clear any output messages
Enable	Enable the software component
FindParentWithID	Returns an attached parent that satisfies the specified ID.
FindParentWithType	Returns an attached parent that satisfies the specified type.
FindRootWithID	Returns a root object that satisfies the specified ID.
FindRootWithType	Returns a root object that satisfies the specified type.
Initialise	This method is called whenever some key parameters are changedand any new local variables are required to be recalculated. Thiscan be called by the software chains if a configuration of somevalues are updated.
