A Calculating Method for the Fault Detection and Exclusion in the WAAS

Applied Mechanics and Materials, 2013
A 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.

Fast multi-fault detection and exclusion approach for GNSS integrity monitoring

, 2013
Integrity monitoring is considered now as an important part of an autonomous navigation system. Localization sensors faults, due to systematic malfunctioning, require integrity reinforcement of multi-sources information fusion method through systematic analysis and reconfiguration method in order to exclude the erroneous information from the fusion ...

Using Delta Range for Fault Detection/Exclusion on GPS Positioning

Asian Journal of Control, 2011
AbstractConventionally, 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), 2015
Integrity 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, 2017
This 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.

Solution separation and Chi-Squared ARAIM for fault detection and exclusion

2014 IEEE/ION Position, Location and Navigation Symposium - PLANS 2014, 2014
Future 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-

GPS/INS integration with fault detection and exclusion in shadowed environments

2008 IEEE/ION Position, Location and Navigation Symposium, 2008
This paper presents a method for GPS/INS operation in shadowed environments such as urban canyons and rural foliage cover. Shadowing causes a combination of multipath and signal attenuation which results in increased uncertainty in the GPS observables and sometimes complete loss of satellite tracking.

An integrated fault detection and exclusion scheme to support aviation navigation

Aerospace Systems, 2019
This paper proposes a novel integrity monitoring scheme against global navigation satellite systems (GNSS) fault for civil aviation navigation. The main contributions are (a) developing an efficient user algorithm that integrates fault detection and exclusion (FDE) functions, and (b) deriving the analytical methods to quantify its corresponding ...

Fault Detection and Exclusion Performance Using GPS and GLONASS

Navigation, 1995
Analysis of the RTCA Special Committee (SC)-159 baseline fault detection and exclusion (FDE) algorithm has been performed to determine whether a combined GPS/GLONASS system could satisfy availability requirements for a primary-means air navigation system.
