On the Effect of Stabilization Methods for Quaternion Invariants on the Uncertainty in Optimization-based Estimation

The handling of 3D orientations is a common element in many problems that arise in the estimation and control of dynamic systems. Over-parametrizations such as unit quaternions are commonly used to avoid singularities but come with the property of an …
