Cooperative Localization for Autonomous Underwater Vehicles

Alexander Bahr

Self-localization of an underwater vehicle is particularly challenging due to the absence of Global Positioning System (GPS) reception or features at known positions that could otherwise have been used for position computation. Thus Autonomous Underwater V ...

2.5D Infrared Range and Bearing System for Collective Robotics

Dario Floreano, Jean-Christophe Zufferey, Timothy Stirling, James Roberts

In the growing field of collective robotics, spatial co-ordination between robots is often critical and usually achieved via local relative positioning sensors. We believe that range and bearing sensing, based on infrared technology, has the potential to f ...

Toward a person-follower robot

Solaiman Shokur

In this article we described the attempt to build a robot able to locate and follow an human target moving in a domestic environment. After a brief review of the state of the art in relative location technologies, we described our approach that aims to dev ...

Performance Analysis of Mobile Station Location Using Hybrid GNSS and Cellular Network Measurements

Pierre-André Farine, Cyril Botteron, Elham Firouzi

Recently, different hybrid GNSS/cellular methods combining GNSS measurements with cellular network measurements have been proposed. These methods are designed to improve the availability (and accuracy) of position determination in situations where few sate ...

Cramer-Rao bounds for the estimation of multipath parameters and mobiles' positions in asynchronous DS-CDMA systems

Cyril Botteron

Commercial applications for the location of subscribers of wireless services continue to expand. Consequently, finding the Cramer–Rao lower bound (CRLB), which serves as an optimality criterion for the location estimation problem, is of interest. In this p ...

Adaptive angle of arrival estimation for multiuser wireless location systems

Ali H. Sayed

Reliable positioning of CDMA cellular users in a mobile environment relies on accurate knowledge of the time-of-arrival (TOA) and angle-of-arrival (AOA) of the first arriving ray. An adaptive procedure is developed for AOA estimation under multipath and mu ...

GPS-free Positioning in Mobile Ad-Hoc Networks

Jean-Pierre Hubaux, Srdan Capkun

We consider the problem of node positioning in ad hoc networks. We propose a distributed, infrastructure- free positioning algorithm that does not rely on GPS (Global Positioning System). Instead, the algorithm uses the distances between the nodes to build ...
