Class AttitudeReferenceCorrectionSoftware

Namespace
NominalSystems.Classes
Assembly
NominalSystems.Classes.dll

This module reads in the attitude reference R and applies a fixed rotation to give a corrected reference Rc. This can be used to modify the reference directly, or to allow a general body-fixed frame Bc to align with the reference R.

In the latter case, assume a body frame B, and a corrected body frame Bc which we want to align with frame R. To do this, frame B is aligned with a corrected reference frame Rc. This module produces the corrected reference frame Rc such that when B aligns with Rc, Bc aligns with R.
