BDS/LEO ARAIM Subset Selection Method

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2021
In 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

2012
Receiver 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.

Standards for ARAIM ISM Data Analysis

ION Pacific PNT, 2019
Advanced 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.

Extending ARAIM to Terrestrial Systems

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation
Adapting the ARAIM methodology to suit terrestrial ranging systems requires adequate configuration of its input parameters. The configuration must be designed to preserve the integrity of the position solution, while, at the same time, supporting meaningful values of RNP.

Nominal Range Error Analysis of BDS for ARAIM

The International Technical Meeting of the The Institute of Navigation, 2021
The 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.

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 Temporal Correlation Effect on PHMI

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2018
The current Advanced Reciever Autonomous Integrity Monitoring (ARAIM) airborne user algorithm [1] takes a simple approach to modelling the integrity risk, i.e., the specific risk of loss of integrity for a given approach is allocated to each epoch so that the user receiver can derive its protection level.

ARAIM with More than two Constellations

ION Pacific PNT, 2019
Future 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 ...

Galileo Characterization as Input to H-ARAIM and SBAS DFMC

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2019
The characterization of Galileo Open Service signal-in-space (SiS) represents an essential input to Safety-of-Life (SoL) applications like Horizontal ARAIM (Advanced Receiver Autonomous Integrity Monitoring) and SBAS (Satellite Based Augmentation System) in particular EGNOS V3. This paper describes the IFMEA (Integrity Failure Mode and Effect Analysis)

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.
