Solution Separation Versus Residual-Based RAIM
TL;DR: A detailed comparison of residual-based and solution separation RAIM is presented and it is shown that the integrity monitoring performance of SS RAIM can be superior to RB RAIM because SS test statistics are tailored to the fault hypotheses, and to the state of interest.

Kalman Filter-Based Integrity Monitoring Against Sensor Faults
Mathieu Joerger,Boris Pervan +1 more
TL;DR: This paper introduces a new Kalman filter-based method for detecting sensor faults in linear dynamic systems that enables direct evaluation of the integrity risk, which is the probability that an undetected fault causes state estimate errors to exceed predefined bounds of acceptability.

An INS Monitor to Detect GNSS Spoofers Capable of Tracking Vehicle Position
TL;DR: A new monitor that uses inertial navigation system measurements to detect spoofing attacks on global navigation satellite system (GNSS) receivers is described and evaluated, showing that GNSS spoofing is easily detected, with high integrity, unless the spoofer's position-tracking devices have unrealistic, near-perfect accuracy, and no delays.
