EDA: New System for Improving Navigation Standards (Totem Plus)

The Totem System

The Totem system supports fault-tolerant applications in which distributed processes cooperate to perform a commontask and in which replicated data must be updated consistently in the presence of asynchrony and faults. Reliable totally ordered delivery of messages to processes within process groups is provided on a single local-area network or over multiple local-area networks interconnected by...

Improving Aiding techniques for USBL Tightly-Coupled Inertial Navigation System

This paper presents two Tightly-Coupled fusion techniques to enhance position, velocity and attitude estimation based on position fixes of an Ultra-Short Base Line (USBL) positioning system with low update rates and the high rate Inertial Navigation System (INS) outputs, subject to bias and unbounded drift. In this framework, the vehicle interrogates transponders placed at known positions of th...

A New Beacon Navigation System

In this paper a new beacon localisation system for mobile robots in indoor environments is presented. Laser and radiofrequency technologies are combined in order to determine robot's position and orientation by means of a triangulation algorithm. The system allows the identification of the different beacons, which provides the robot's absolute position without requiring the maintenance of a pos...

Preliminary System Design for an EDA Assistant

Data analysis plays a central role in our attempts to understand the behavior of complex systems. While research in both statistics and arti cial intelligence has addressed issues in the automation of later stages of analysis, such as theory generation, model selection, and experiment design [7], less attention has been given to initial exploration of data. Deriving structure from data is never...
