Residual Based Fault Detection and Exclusion Methods Applied to Ultra-Wideband Navigation
Measurement: Journal of the International Measurement Confederation, 2021Global Navigation Satellite System (GNSS) has become the main technology in terms of navigation technologies, as it ensures a worldwide absolute outdoor positioning. The transportation sector employs this technology to obtain a position, velocity and time solution for the corresponding outdoor application.

Solution Separation and Chi-Squared ARAIM for Fault Detection and Exclusion
2014 IEEE/ION Position, Location and Navigation Symposium - PLANS 2014, 2014Future multi-constellation Global navigation satellite system (GNSS) will provide a large number of redundant ranging signals, which will improve the performance of receiver autonomous integrity monitoring (RAIM), but it will also increase the probability of satellite faults, thereby increasing the continuity risk. In response, in this paper, a new Chi-

A Fault Detection and Exclusion Estimator Designed for Integrity
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021We describe an estimator that merges two functions that are key in integrity monitoring: fault detection and fault exclusion. One of the main contributions of this work is the derivation of a protection level with an analytical proof of both integrity and continuity for the proposed estimator.

Optimising Fault Detection and Exclusion in positioning
2010 Ubiquitous Positioning Indoor Navigation and Location Based Service, 2010Reliability and integrity has become increasingly important in ubiquitous positioning systems, and particularly in critical applications. To implement reliability and integrity measures, Fault Detection and Exclusion (FDE) procedures should be used. However, the current FDE procedures in the chi-square test and the outlier test are suboptimal in terms ...

A Calculating Method for the Fault Detection and Exclusion in the WAAS
Applied Mechanics and Materials, 2013A calculating method for the fault detection and exclusion (FDE) played a very important role in the Wide Area Augmentation System (WAAS). When the WAAS was not available, the algorithm of the FDE could provide the monitoring information for the navigation position solution.

Using Delta Range for Fault Detection/Exclusion on GPS Positioning
Asian Journal of Control, 2011AbstractConventionally, the well‐known position‐velocity‐acceleration (PVA) model is adopted as the dynamic model of the Kalman filter for global positioning system (GPS) positioning. Nevertheless, when a moving vehicle corners in the situation of accelerated motion, the conventional PVA model without using extra sensors is no longer adequate for ...

Fault detection and exclusion method for a tightly coupled localization system
2015 International Conference on Advanced Robotics (ICAR), 2015Integrity monitoring for a positioning method permit us to guarantee a high integrity localization which is needed for an autonomous navigation system. Different approaches for localization integrity monitoring have been developed. In this paper, we propose a Fault Detection and Exclusion (FDE) method based on information metrics since it provides ...

Feasibility of Fault Exclusion Related to Advanced RAIM for GNSS Spoofing Detection
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2017This paper will present an exercise to verify the usefulness of statistical testing of measurement residuals of an overdetermined position solution followed by measurement subset selection for spoofing detection and mitigation for certain spoofing events, to be especially beneficial when multi-GNSS is considered.
