Cooperative Relative Positioning
IEEE Pervasive Computing, 2010Many pervasive applications deal with relative positions between interacting entities rather than global coordinates. The Relate project developed sensing methods and a modular system architecture for peer-to-peer relative positioning. It studied the methods and architecture in application case studies on mobile spatial interaction, firefighter ...

Cooperative Positioning with MagicMap
2007 4th Workshop on Positioning, Navigation and Communication, 2007We present MagicMap, a cooperative, hybrid positioning system developed at the Humboldt-University in Berlin. While most other positioning systems are limited to specific scenarios and technologies our system provides means to incorporate any available wireless networking technology.

Privacy-preserving Cooperative Positioning
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2020We address the issue of user privacy in the context of “collaborative” positioning, wherein information is passed between and processed by multiple cooperative agents with the goal of achieving high levels of positioning accuracy. In particular, we evaluate the feasibility of applying a layer of encryption to a linear least squares (LS) algorithm for ...

Cooperative Vehicle Position Estimation
2007 IEEE International Conference on Communications, 2007We present a novel cooperative vehicle position estimation algorithm, which can achieve higher levels of accuracy and reliability than existing GPS based positioning solutions by making use of inter-vehicle distance measurements taken by a radio ranging technology. Our algorithm uses signal strength based inter-vehicle distance measurements, road maps,

Cooperative Positioning for the Converged Networks
VTC Spring 2009 - IEEE 69th Vehicular Technology Conference, 2009The wireless cooperative positioning scheme based on information fusion is proposed in this paper. The scheme combines large-scale TOA and small-scale distance measured in the converged networks. The asymptotically efficient estimator based on maximum likelihood (ML) estimation is introduced in the proposed scheme, and the position of mobile terminal ...

AOA Cooperative Position Localization
IEEE GLOBECOM 2008 - 2008 IEEE Global Telecommunications Conference, 2008In wireless sensor networks, it is very important to obtain an accurate position of each sensor node. In this paper, we consider the potential of Ultra Wideband (UWB) signals for positioning due to its special characteristics. Accurate angle of arrival (AOA) can be obtained using UWB antenna arrays. We propose a new cooperative positioning method based

Cooperative positioning with multiple robots
Proceedings of the 1994 IEEE International Conference on Robotics and Automation, 2002A number of positioning identification techniques have been used for mobile robots. Dead reckoning is a popular method, but is not reliable when a robot travels long distances or over an uneven surface because of variations in wheel diameter and wheel slippage.

Cooperative Infrastructure-Based Vehicle Positioning
2016 IEEE 84th Vehicular Technology Conference (VTC-Fall), 2016Many Advanced Driver Assistance Systems rely on an accurate self-localization. This is usually provided by Global Navigation Satellite Systems (GNSS) along with on-board sensors, such as inertial sensors, speed sensors, wheel-tick sensors and steering wheel angle sensors.

Integrity for Multi-Sensor Cooperative Positioning
IEEE Transactions on Intelligent Transportation Systems, 2021A cooperative integrity monitoring (CIM) algorithm is proposed in this work. Under the CIM architecture, the algorithm can fully exploit the global navigation satellite system (GNSS) data and inter-vehicle measurements data to improve the detection and isolation of faulty measurements due to multipath or non line of sight (NLOS).

Cooperative Positioning in Underwater Sensor Networks
IEEE Transactions on Signal Processing, 2010We consider cooperative positioning using acoustic range measurements for underwater sensor networks, including networks formed by autonomous unmanned underwater vehicles (UUVs). Severe multipath scattering from the seabed and ocean surface can result in inaccurate range measurements.
