GPS/INS integration with fault detection and exclusion in shadowed environments
2008 IEEE/ION Position, Location and Navigation Symposium, 2008This paper presents a method for GPS/INS operation in shadowed environments such as urban canyons and rural foliage cover. Shadowing causes a combination of multipath and signal attenuation which results in increased uncertainty in the GPS observables and sometimes complete loss of satellite tracking.

Fault Detection and Exclusion Performance Using GPS and GLONASS
Navigation, 1995Analysis of the RTCA Special Committee (SC)-159 baseline fault detection and exclusion (FDE) algorithm has been performed to determine whether a combined GPS/GLONASS system could satisfy availability requirements for a primary-means air navigation system.

An integrated fault detection and exclusion scheme to support aviation navigation
Aerospace Systems, 2019This paper proposes a novel integrity monitoring scheme against global navigation satellite systems (GNSS) fault for civil aviation navigation. The main contributions are (a) developing an efficient user algorithm that integrates fault detection and exclusion (FDE) functions, and (b) deriving the analytical methods to quantify its corresponding ...

Faults in the GNSS measurements are the main reason for uncertainty positioning. Accuracy can thus be maximized by selecting only those observations least contaminated by faults to form the navigation solution (positioning) and discarding the rest. In this paper, we propose an algorithm to solve the problem of multi faults in the GNSS observations ...

Fault detection and exclusion of cycle slips for carrier-phase in GNSS positionning.
2015This paper presents an algorithm of a standalone GPS positioning system that uses both the C/A code and LI carrier-phase measurements. The algorithm is based on a dynamic state vector estimation using Information Filter (IF) and information theory metrics. The GPS carrier-phase measurements suffer from a common error source which is the cycle slips (CS)
