Analyzing Satellite Orbit Error for ARAIM Offline Monitoring

2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020
In this paper, we propose a new approach to generate the Integrity Support Message (ISM) for Advanced Receiver Autonomous Integrity Monitoring (ARAIM). In our approach, we analyze the satellite ephemeris parameters that directly contribute to the satellite position error and thus, result in the ranging error for an ARAIM user.

Assessing of Aircraft Banking on ARAIM Performance

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2018
Significant differences in the quality of measurements made by a ground receiver compared to an avionics receiver may arise due to the dynamics of the aircraft. Banking for turns, in particular, can cause the GNSS measurements to be adversely affected in a number of ways. This may include adverse effects on multipath, satellite outages, and cycle slips.

ARAIM Continuity and Availability Assertions, Assumptions, and Evaluation Methods

The International Technical Meeting of the The Institute of Navigation, 2020
In this paper, we describe assumptions and assertions needed to account for continuity and availability risks in Advance Receiver Autonomous Integrity Monitoring (ARAIM). We identify key differences with current RAIM-based operations, including the potential of ARAIM to not require systematic pre-flight availability screening.

Keynote: Validation of the Unfaulted Error Bounds for ARAIM

ION Pacific PNT, 2017
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) requires accurate modeling of the unfaulted satellite Signal-In-Space (SIS) error distributions in order to properly calculate integrity risk. This error distribution is most commonly described by two terms: the nominal bias, bnom, and the User Range Accuracy, URA.

GNSS Environment for BDS Based ARAIM

The International Technical Meeting of the The Institute of Navigation, 2017
Researchers in the European Union and in the United States are investigating Advanced RAIM (ARAIM) for world-wide vertical guidance of aircraft. As a member of the four core constellations, Beidou has completed its regional system construction and is developing the global constellation. Beidou is accordingly possible to serve for ARAIM.

GPS SISRE/URA Integrity Analysis for ARAIM

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016
The modernization of current GNSS services such as GPS, and the development and deployment of new constellations, such as Galileo, allow for new concepts as ARAIM to be proposed and raise interest among the aviation community. The ARAIM concept was proposed in the framework of the GNSS Evolutionary Architecture Study (GEAS) to define a seamless ...

Multi Gaussian Distribution for ARAIM SISRE Overbound

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019
This paper presents a novel Signal-in-Space Range Error (SISRE) overbounding methodology based on the combination of two Gaussian distributions. Based on empirical evidence from GPS and Galileo historical SISRE data, by partitioning the error distribution into core and tail sets, this work introduces an individual Single Gaussian (SG) overbound for ...
