Abstract

The development of reliable attitude, position and linear velocity estimation algorithms for autonomous navigation systems is instrumental in many applications such as autonomous underwater vehicles, autonomous ground vehicles and unmanned aerial vehicles. It is well known that there is no sensor that can directly measure the orientation of a rigid body moving in a three-dimensional space. This fact calls for the development of suitable attitude estimation algorithms that provide the attitude using the information provided by a set of sensors such as those of inertial measurement units (IMUs). Moreover, it is challenging to obtain the orientation of a rigid body, subject to non-negligible linear accelerations, using low cost IMUs and standard attitude estimation algorithms. It is also challenging to obtain (simultaneously and globally) the orientation, position and linear velocity of a system navigating in GPS-denied environments (e.g., indoor applications). Therefore, developing reliable estimation algorithms that provide the attitude, position and linear velocity, with strong stability guarantees, is of great importance (from the theoretical and practical points of view) for autonomous navigation systems. In this talk, we will present an overview, some new results and pertinent challenges related to the estimation problems for autonomous navigation systems.
