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 …

Towards robust sensor fusion for state estimation in airborne applications using GNSS and IMU

Precise estimation of position, velocity, and orientation is crucial for robust control in airborne applications such as the fast maneuvering power kites for airborne wind energy generators. In this paper we present a sensor fusion approach for the …
