In this paper, we present an algorithmic framework for signal‐geometry‐based approaches
of GNSS spoofing detection. We formulate a simple vs. simple hypothesis test independent …

Recent work has demonstrated that signal-geometry-based approaches are a powerful
mean for a GNSS receiver to detect spoofing. These techniques, leveraging the spatial …

Electromagnetic interference can degrade civil Global Navigation Satellite System (GNSS)
signals and services, and in some cases result in integrity failures. The aviation community …

Due to the high reliance of daily activities on the Global Navigation Satellite System (GNSS),
its security is one of the major concerns for research and industry. Most navigation and …

The implementation of adaptive array processing such as the minimum variance
distortionless response (MVDR) requires the knowledge of a reference waveform or a …

Summary The general Global Navigation Satellite System (GNSS) receiver faces several
challenges because of jamming signals, spoofing signals, and multipath signals, which …

In this paper we present a sequential likelihood ratio test to detect a GNSS spoofing attack
using information from multiple measurements. We develop an analytical solution for the …

In this work, we present mitigation algorithms to protect GNSS receivers against malicious
interference. Maritime applications with an antenna array-based receiver are considered as …
