Geometric Reduced-Attitude Tracking Under a Time-Varying Conic Constraint via Smooth Reference-Shaping
Pedro Santos, Joel Reis, Paulo Oliveira +1
This letter studies reduced-attitude tracking for a rigid body on the 2-sphere S2 under a time-varying conic constraint. Using a kinematic model on S2, we first propose a geometric…
The Variational Attitude Estimator in the Presence of Bias in Angular Velocity Measurements
Maziar Izadi, Sasi Prabhakaran Viswanathan, Amit Kumar Sanyal +2
Estimation of rigid body attitude motion is a long-standing problem of interest in several applications. This problem is challenging primarily because rigid body motion is describe…
Approximate Maximum Likelihood Source Localization from Range Measurements Through Convex Relaxation
Pınar Oğuz-Ekim, João Gomes, João Xavier +2
This work considers the problem of locating a single source from noisy range measurements to a set of nodes in a wireless sensor network. We propose two new techniques that we desi…
Robust Simultaneous Localization of Nodes and Targets in Sensor Networks Using Range-Only Measurements
Pınar Oğuz-Ekim, João Gomes, João Xavier +1
Simultaneous localization and tracking (SLAT) in sensor networks aims to determine the positions of sensor nodes and a moving target in a network, given incomplete and inaccurate r…
Position USBL/DVL Sensor-based Navigation Filter in the presence of Unknown Ocean Currents
M. Morgado, P. Batista, P. Oliveira +1
This paper presents a novel approach to the design of globally asymptotically stable (GAS) position filters for Autonomous Underwater Vehicles (AUVs) based directly on the nonlinea…
