Residual based fault detection and exclusion methods applied to Ultra-Wideband navigation
Measurement: Journal of the International Measurement Confederation, 2021 Global 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.

A Framework for Collaborative All-Source Navigation With Fault Detection and Exclusion
IEEE Transactions on Aerospace and Electronic Systems, 2022 The ARMAS-SOM framework fuses collaborative all-source sensor information in a resilient manner with fault detection, exclusion, and integrity solutions recognizable to a GNSS user. This framework uses a multifilter residual monitoring approach for fault

Fault detection and exclusion using solution separation and chi-squared ARAIM
IEEE Transactions on Aerospace and Electronic Systems, 2016This paper provides new integrity and continuity risk evaluation methods for fault detection and exclusion (FDE) using receiver autonomous integrity monitoring (RAIM). These methods are developed for both solution separation (SS) and Chi-squared RAIM: they capture the fact that exclusion enables continuity risk reduction in exchange for a higher ...

IEEE Transactions on Aerospace and Electronic Systems, 2020
In this article, the problem of detecting and excluding faulty global navigation satellite systems (GNSSs) measurements at the receiver end is formulated as a parameterized quadratic programming (PQP) problem. Compared to the existing fault detection and exclusion (FDE) methods, which mostly rely on exhaustive search, the PQP method is computationally ...

Fault detection and exclusion of cycle slips for carrier-phase in GNSS positionning.
, 2015 This paper presents an algorithm of a standalone GPS positioning system that uses both the C/A code and LI carrier-phase measurements. The algorithm is based on a dynamic state vector estimation using Information Filter (IF) and information theory metrics. The GPS carrier-phase measurements suffer from a common error source which is the cycle slips (CS)

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 ...
