Hysteresis in RAIM

, 2009
Absolute RAIM algorithms proposed for vertical guidance are based on a snapshot approach. At a given time, each satellite has a probability of being in a faulted state which does not depend on how long the satellite has been in view.

A-RAIM and R-RAIM Performance using the Classic and MHSS Methods

Journal of Navigation, 2013
Two Receiver Autonomous Integrity Monitoring (RAIM) architectures, Advanced RAIM (A-RAIM) and Relative RAIM (R-RAIM), are compared with two different RAIM algorithms, the Classic method and the Multiple Hypothesis Solution Separation (MHSS) method.

Differential RAIM and relative RAIM for orbit ephemeris fault detection

Proceedings of the 2012 IEEE/ION Position, Location and Navigation Symposium, 2012
This paper introduces new monitors for the detection of orbit ephemeris faults affecting differential carrier phase measurements in a shipboard aircraft landing application. Two shipboard monitors are first designed. While they provide high detection performance against two targeted fault types, they are ineffective against the other types of orbit ...

Bounding Fault Probabilities for Advanced RAIM

IEEE Transactions on Aerospace and Electronic Systems, 2020
Advanced Receiver Autonomous Integrity Monitoring (ARAIM) is under development to support both lateral and vertical guidance. A key component of ARAIM is the Integrity Support Message (ISM) which contains validated input parameters including the probabilities of satellite and constellation failure. A service commitment for the former is provided in the

RAIM: Redundant array of independent motes

2017 International Conference on Networked Systems (NetSys), 2017
Wireless Sensor Networks in real world context are per se error-prone; motes can be lost, destroyed, corrupted, or stolen. Some scenarios demand a high level of confidentiality and integrity so that an attacker cannot access or alter the secret data. Other setups may require a high level of redundancy so that data from many motes can be recovered by ...

Revision of RAIM Implementation for Maritime

ION GNSS+, The International Technical Meeting of the Satellite Division of The Institute of Navigation, 2020
The field of GNSS integrity comprises a plethora of integrity related algorithms, each featured with different characteristics. These algorithms use a priori information of some parameters in order to provide integrity information to the user. One type of these algorithms, RAIM, is extensively used in the maritime domain in order to provide an ...

Augur: RAIM for dummies

1999 IEEE Aerospace Conference. Proceedings (Cat. No.99TH8403), 1999
When pilots want to fly Basic Area Navigation in Europe using the Global Positioning System (GPS) they will have to check whether this can be done safely. Augur can perform such a check by predicting whether GPS can provide sufficient positioning integrity; in case it cannot, flight dispatch should not be made.
