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

Technological developments over the past two decades have resulted in the development of
more accurate and lightweight low-cost magnetic and inertial measurement units (MIMUs) …

This paper addresses the landing problem of a vertical take-off and landing vehicle,
exemplified by a quadrotor, on a moving platform using image-based visual servo control …

This paper deals with the construction of nonlinear observers for navigation purposes. We
first present a globally exponentially stable observer for attitude and gyro bias, based on …

Attitude estimation is a crucial aspect for navigation and motion control of autonomous
vehicles. This concept is particularly true in the case of unavailability of localization sensors …

We address the complete state estimation problem of unmanned aerial vehicles, even under
high-dynamic 3-D aerobatic maneuvers, while using low-cost sensors with bias variations …

This paper addresses the problem of distributed state estimation in a multi-vehicle
framework. Each vehicle aims to estimate its own state relying on locally available …

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 …

Attitude estimation is one of the core frame-works used for navigating an unmanned aerial
vehicle from one place to the other. This paper presents an Euler-based non-linear …

This paper is focused on an attitude estimation method for Autonomous Underwater
Vehicles (AUVs). Data acquired by a commercial Micro-Electro-Mechanical Systems …
