Cross-correlation effect of ARAIM test statistic on false alarm risk
GPS Solutions, 2020 International audienceThe requirement for ARAIM continuity risk due to the monitor false alarm has been outlined in earlier works for ARAIM development (WG-C in ARAIM technical subgroup milestone 3 report, 2016).

End-to-End ARAIM demonstrator: magicARAIM suite
2020 European Navigation Conference (ENC), 2020Currently, ABAS (aircraft based augmentation system) is covered by RAIM (Receiver Autonomous Integrity Monitoring), which allows assuring the integrity of the navigation information received by the aircraft from GPS satellites for non-precision approach services. The receivers perform integrity checks considering a set of fixed assertions regarding the

Determination of Fault Probabilities for ARAIM
IEEE Transactions on Aerospace and Electronic Systems, 2019Two critical parameters for advanced receiver autonomous integrity monitoring are the probability of satellite fault and the probability of constellation fault. This paper provides specific definitions for each of these fault types. We describe how these faults are evaluated and how to estimate their probability occurrence.

Determination of fault probabilities for ARAIM
2016 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2016Two critical parameters for Advanced Receiver Autonomous Integrity Monitoring (ARAIM) are the probability of satellite fault, Psat, and the probability of constellation fault, Pconst. A satellite fault is one whose root cause is only capable of affecting a single satellite; while a constellation fault has a root cause that is capable of affecting more ...

Continuity and Availability Evaluation in Horizontal ARAIM
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021In this paper, we describe methods to account for loss of continuity (LOC) caused by receiver alerts and unusually high protection levels caused by satellite outages in Horizontal Advance Receiver Autonomous Integrity Monitoring (H-ARAIM). First, we derive receiver alert thresholds to limit the risk of LOC: the derivation starts from the definition of ...

Standards for ARAIM ISM Data Analysis
ION Pacific PNT, 2019Advanced Receiver Autonomous Integrity Monitoring (ARAIM) relies on accurate and safe information to be provided to the aircraft through an Integrity Support Message (ISM). The ISM safety parameters are based on service commitments established by each core GNSS constellation.

ARAIM with More than two Constellations
ION Pacific PNT, 2019Future Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is expected to bring significant global navigation performance improvement to civil aviation. Currently, the ARAIM research activities are led by a joint working group of the United States (U.S.) and the European Union (E.U.), which focuses on dual-constellation scenario using the Global ...

BDS/LEO ARAIM Subset Selection Method
ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021In recent years, multi-GNSS have developed vigorously, and the idea of using low earth orbit (LEO) communication satellites for navigation has gradually become a reality. Since a single constellation cannot meet the performance requirements of LPV- 200 alone, LEO constellation with navigation payload can be used as a navigation system to perform ...

The Study and Analysis on ARAIM Performance
2012Receiver autonomous integrity monitoring (RAIM) is the key approach to monitor the integrity of Global Navigation Satellite System (GNSS). Advanced RAIM (ARAIM) is the upgrade. The paper focuses on the ARAIM algorithm and tries to make some progress. According simulation and analysis, the performance of ARAIM is validated.

Nominal Range Error Analysis of BDS for ARAIM
The International Technical Meeting of the The Institute of Navigation, 2021The Advanced Receiver Autonomous Integrity Monitoring (ARAIM) requires a minimum performance level of the satellite constellation that is used for aircraft navigation. The distribution of the satellite Signal-In-Space (SIS) range error needs to be sufficiently characterized considering the correlation in error terms.
