GNSS Environment for BDS Based ARAIM
The International Technical Meeting of the The Institute of Navigation, 2017Researchers 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.

ARAIM Continuity and Availability Assertions, Assumptions, and Evaluation Methods
The International Technical Meeting of the The Institute of Navigation, 2020In 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, 2017Advanced 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.

Impact of ARAIM Nominal Bias Bounding Techniques on Final ARAIM User Performance
2014Receiver Autonomous Integrity Monitoring (RAIM) has been certified to provide lateral guidance in flight operations ranging from En-route to Non-Precision Approach (NPA). Recent developments in the RAIM algorithm science, namely Advanced RAIM (ARAIM), have suggested a future role in vertically guided operations down to LPV with a decision height of ...

GPS SISRE/URA Integrity Analysis for ARAIM
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2016The 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, 2019This 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 ...
