Description

This attitude guidance module computes the velocity pointing reference frame state. The orbit can be any type of Keplerian motion, including circular, elliptical or hyperbolic. The velocity coordinate system is defined by the unit vectors {i_n, i_v, i_h}, with velocity vector i_v, angular momentum vector i_h = r^ x v^, and normal vector i_n to complete the triad.

Properties

Declared	Description
In_EphemerisMsg	Ephemeris message describing the current state of thetarget planet
In_NavigationTranslationMsg	Navigation message describing the actual or estimated stateof the parent body
In_PlanetStateMsg	The input planet state message that contains the gravitationalMu parameter for the orbiting body.
Out_AttitudeReferenceMsg	Output attitude reference message

Inherited	Description
IsEnabled	Is true if the object is currently enabled.

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.
