Localizability Analysis for GPS/Galileo Receiver Autonomous Integrity Monitoring

Journal of Navigation, 2004
With the European Commission (EC) and European Space Agency's (ESA) plans to develop a new satellite navigation system, Galileo and the modernisation of GPS well underway the integrity of such systems is as much, if not more, of a concern as ever. Receiver Autonomous Integrity Monitoring (RAIM) refers to the integrity monitoring of the GPS/Galileo ...

Flight Testing of Advanced Receiver Autonomous Integrity Monitoring and Dual Polarized Antenna

2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020
The United States Air Force Test Pilot School Test Management Project, “Have DRAGON”, conducted flight tests on two technologies aimed at improving the robustness of airborne GNSS navigation. The program was conducted in close partnership with the Stanford University GPS Lab which developed Advanced Receiver Autonomous Integrity Monitoring (ARAIM) and ...

A Proposed Concept of Operations for Advanced Receiver Autonomous Integrity Monitoring

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2018
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is a concept that extends today’s RAIM by incorporating dual frequency and multiple constellations. ARAIM will dramatically improve the availability of horizontal guidance, and has the possibility to evolve to provide worldwide vertical guidance.

Research on Receiver Autonomous Integrity Monitoring Technology for Rocket Onboard GNSS Receiver

2013
The Receiver Autonomous Integrity Monitoring (RAIM) Technology can make the fault detection and identification with the redundant Global Navigation Satellite System (GNSS) information independently. In this paper, the RAIM technology is investigated for the high-speed rocket onboard GNSS receiver.

A Framework for Bayesian Receiver Autonomous Integrity Monitoring in Urban Navigation

Navigation, 2011
: A Bayesian framework for RAIM designed to meet the requirements of today's urban navigation is introduced. The framework is general in the sense that when contaminated observations can be modeled, integrity information can be computed. We consider the case of positioning in the presence of multipath signals.

Advanced Receiver Autonomous Integrity Monitoring in Tightly Integrated GNSS/Inertial Systems

2020 DGON Inertial Sensors and Systems (ISS), 2020
This paper deals with the tight integration of Inertial Measurement Units (IMU), Global Navigation Satellite Systems (GNSS) and the concept of Advanced Receiver Autonomous Integrity Monitoring (ARAIM). While the integration of an IMU and GNSS to an integrated GNSS/Inertial system is well known and widespread, the use of the ARAIM concept in inertial ...

On the Availability of Fault Detection and Exclusion in GNSS Receiver Autonomous Integrity Monitoring

Journal of Navigation, 2009
Global Navigation Satellite System (GNSS) Receiver Autonomous Integrity Monitoring (RAIM) is essential for safety-of-life and liability critical applications. This paper discusses two fundamentally different ways to assess the integrity risk of an operation with RAIM, based on a different amount of information available: the expected (or average ...

GNSS Receiver Autonomous Integrity Monitoring Algorithm Based on Robust Strong Tracking Filtering

2018 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC), 2018
In this paper, the effects of Kalman model error and gross errors in measurement data on the performance of RAIM (Receiver Autonomous Integrity Monitoring) are studied. Firstly, the deviations of RAIM detection statistic caused by the above errors are calculated. And then an improved RAIM detection algorithm based on robust strong tracking filtering is
