Equivariance is a common and natural property of many nonlinear control systems,
especially those associated with models of mechatronic and navigation systems. Such …

It is proposed to estimate wind velocity, Angle-Of-Attack (AOA) and Sideslip Angle (SSA) of a
fixed-wing Unmanned Aerial Vehicle (UAV) using only kinematic relationships with a …

This paper concerns the problem of attitude determination and estimation. The early
applications considered algebraic methods of attitude determination. Attitude determination …

This paper presents a viable quaternion-based complementary observer (CO) that is
designed for rigid body attitude estimation. We claim that this approach is an alternative one …

This paper introduces two novel nonlinear stochastic attitude estimators developed on the
Special Orthogonal Group with the tracking error of the normalized Euclidean distance …

This paper proposes a novel observer-based controller for Vertical Take-Off and Landing
(VTOL) Unmanned Aerial Vehicle (UAV) designed to directly receive measurements from a …

Navigation is a term with broad usage in everyday life and can mean the act of moving,
moving through an unknown environment, ascertaining a craft's position, or even browsing …

Aiming to improve the accuracy of navigation systems during GPS outages, this paper
presents an adaptive-gain complementary filter for attitude estimation. With the introduction …

In this article, we suggest that a strapdown inertial navigation system based on
microelectromechanical system (MEMS) inertial sensors is a useful addition to a vessel with …

Navigation solutions suitable for cases when both autonomous robot's pose (ie., attitude and
position) and its environment are unknown are in great demand. Simultaneous Localization …
