Receiver Autonomous Integrity Monitoring (RAIM) of GPS and GLONASS

Navigation, 1993
A receiver autonomous integrity monitoring (RAIM) algorithm is proposed, and used to analyze the integrity monitoring capabilities of potential sole-means (or stand-alone) systems based on integrated use of GPS and GLONASS, GPS supplemented with a geostationary overlay, and enhanced GPS constellations.

A measurement domain receiver autonomous integrity monitoring algorithm

GPS Solutions, 2005
One of the key approaches to monitor the integrity of Global Satellite Navigation Systems (GNSS) is receiver autonomous integrity monitoring (RAIM). Existing RAIM algorithms utilise two tests in the position domain (for RAIM availability) and measurement domain (for failure detection).

Extended Receiver Autonomous Integrity Monitoring (eRAIM) for GNSS/INS Integration

Journal of Surveying Engineering, 2010
The integration of globe navigation satellite system (GNSS) with inertial navigation system (INS) is being heavily investigated as it can deliver more robust and reliable systems than either of the individual systems. In order to ensure the integrity of navigation solutions, it is necessary to incorporate an effective quality control scheme which uses ...

Using multi-frequency for GPS positioning and receiver autonomous integrity monitoring

Proceedings of the 2004 IEEE International Conference on Control Applications, 2004., 2005
Algorithms using multi-frequency for GPS positioning and receiver autonomous integrity monitoring (RAIM) are proposed by the authors. In the conventional algorithms, only single frequency L1 is applied. After the L2 and L5 signals are applied, the ionospheric delay can be removed.

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.

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 ...

GNSS receiver autonomous integrity monitoring (RAIM) performance analysis

GPS Solutions, 2005
The availability of GPS signals is a major concern for many existing and potential applications. Fortunately, with the development of Galileo by the European Commission (EC) and European Space Agency (ESA) and new funding for the restoration of the Russian GLONASS announced by the Russian Federation (Revnivykh et al., in European Navigation Conference ...

Ensuring GPS navigation integrity using receiver autonomous integrity monitoring

IEEE Aerospace and Electronic Systems Magazine, 1995
The many advantages of Global Positioning System (GPS) based navigation have created a tremendous amount of interest in using GPS as the primary navigation aid onboard commercial and civil aircraft. Even in the presence of Selective Availability, the accuracy of GPS is sufficient to guide aircraft point-to-point between airports without requiring other

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 ...
