RAIM analysis in the position domain
IEEE/ION Position, Location and Navigation Symposium, 2010Receiver Autonomous Integrity Monitoring (RAIM) is a kind of technical used in domain of GNSS. It can provide warning to user when positioning result deviates from the real position critically. It is, therefore, necessary to demarcate the errors in the position domain on analyzing RAIM performance quantitatively as well as to confirm the relationship ...

: Contemporary Receiver Autonomous Integrity Monitoring (RAIM) algorithms such as that developed by Brown and Chin [1] are designed to allow the user's receiver to supply its own integrity and protect against the development of excessive noise as well as bias, both originating from the ranging measurements. Past RAIM protection levels have assumed that

RAIM algorithms for aided GNSS in urban scenario
2012 Ubiquitous Positioning, Indoor Navigation, and Location Based Service (UPINLBS), 2012Urban canyon is a critical scenario for satellite navigation, because many GNSS signals are blocked by artificial obstacles or severely degraded; in standalone mode GPS, currently the main GNSS, cannot guarantee an accurate and continuous positioning. A possible approach to overcome these limitations is the use of multiple GNSS systems.

PPS RAIM Algorithms and Their Performance*
Navigation, 1995This paper describes several receiver autonomous integrity monitoring (RAIM)-type algorithms that are candidates for use in military Precise Positioning Service (PPS) GPS receivers. Although these PPS RAIM-type algorithms are based on the Standard Positioning Service (SPS) RAIM and RAIM-type algorithms described in RTCA/DO-208, TSO-C129, and elsewhere,

A Baseline GPS RAIM Scheme and a Note on the Equivalence of Three RAIM Methods
Navigation, 1992The RTCA GPS Minimum Operational Performance Standards (MOPS) has now been released, and airborne equipment manufacturers will be expected to meet the specifications given in the MOPS. A considerable portion of the MOPS is devoted to GPS integrity requirements and the associated receiver testing procedures.

RAIM in Integrated Navigation System
2007 8th International Conference on Electronic Measurement and Instruments, 2007In integrated navigation system, several navigation systems work follow certain rules and errors can hardly be avoided in one of the systems. A great error will be caused by using the wrong information to calculate the position of carrier. This article takes GPS for an example, an Autonomous Integrity Monitoring method of satellite navigation receiver ...

Mathematical aspects of GPS RAIM
Proceedings of 1994 IEEE Position, Location and Navigation Symposium - PLANS'94, 2002This paper presents and proves two new theorems that provide deeper understanding of receiver autonomous integrity monitoring (RAIM) methods. The theorems answer the following two questions about RAIM and the least squares navigation solution. (i) Given one set of GPS measurements (a "snapshot"), is it ever possible to determine the navigation error ...

A Position Domain Relative RAIM Method
IEEE Transactions on Aerospace and Electronic Systems, 2011The GNSS Evolutionary Architecture Study (GEAS) Panel has been evaluating future GNSS-based architectures to provide worldwide instrument approach guidance known as LPV-200 in the 2025 to 2030 time frame. One of the architectures being considered by GEAS is based on a new concept called relative receiver autonomous integrity monitoring (RRAIM). In this

The major shortcoming of RAIM FDE is widely recognized to be its occasional lack of availability, in the sense that the integrity level it can protect in any given situation cannot always be smaller than the required alert limit for a given flight operation.
