Recent Trends in Interference Mitigation and Spoofing Detection

International Journal of Embedded and Real-Time Communication Systems, 2012
This paper gives a classification of intentional and unintentional threats, such as interference, jamming and spoofing, and discusses some of the recent trends concerning techniques for their detection and mitigation. Despite the fact that these phenomena have been studied since the early stages of Global Positioning System (GPS), they were mainly ...

Spoofing interference suppression using space-time process for GNSS receiver

2012 5th International Congress on Image and Signal Processing, 2012
Spoofing interference suppression technique for GNSS receiver was deeply discussed. Space-time process and MMSE criterion were applied to anti-spoofing. The combination of PD(Partial Dispreading) and MIRR (Multistage Iterative Rank-reduced) method was proposed to simplify the processing.

Full-Duplex Spoofing Relays for Wireless Surveillance With Inter-Relay Interference Suppression

2020 IEEE 91st Vehicular Technology Conference (VTC2020-Spring), 2020
In this work, we study a scenario where a distant central monitor covertly wiretaps the communication between a pair of suspicious users via several single-antenna full-duplex spoofing relays and a cooperative jammer for wireless surveillance. Under an adaptive transmission policy where the data rate of the suspicious users is determined based on the ...

Interference and Spoofing

2014
This chapter deals with one of the major concerns for reliable use of Global Navigation Satellite Systems (GNSS), providing a description of intentional and unintentional threats, such as interference, jamming, and spoofing. Despite the fact that these phenomena have been studied since the early stages of Global Positioning System (GPS), they were ...

Navigating Interference - Examining In-Flight GNSS Spoofing Patterns and Signal Disruptions

The International Technical Meeting of the The Institute of Navigation
In this study, we present an analysis of GNSS signals collected in-flight on a scheduled commercial flight out of Amman (AMM), Jordan in September 2024. The flight crew took a commercial receiver capable of tracking multiple GNSS constellations and frequencies and recorded GNSS signals from behind the window inside the flight deck.

Research on GNSS Anti-spoofing Interference Algorithm Based on Muti-receiver

2019 IEEE International Conference on Signal, Information and Data Processing (ICSIDP), 2019
In recent years, satellite navigation has been widely and deeply applied in various fields. In order to ensure the security and reliability of navigation information, anti-spoofing interference has become very important. In this paper, we study the anti-spoofing interference algorithm based on pseudorange of dual receivers. We establish the real signal

Spoofing Interference Suppression for GNSS Based on Estimating Steering Vectors

2015
The paper proposes a spoofing interference suppression algorithm for multiple spoofing interferences existing simultaneously. First, the signals which received from the reference antenna array are captured. The information about visible satellite signals’ Doppler frequency and code delay are acquired.

GNSS Spoofing, Jamming, and Multipath Interference Classification using a Maximum-Likelihood Multi-Tap Multipath Estimator

The International Technical Meeting of the The Institute of Navigation, 2017
This paper experimentally evaluates the application of existing multipath mitigation technology in conjunction with in-band power monitoring for the purpose of GNSS interference classification. In particular, GNSS interference detection and classification metrics derived from the output of a multiple-correlation tap, maximum-likelihood multipath ...

Multiple Fano-Like Transmission Mediated by Multimode Interferences in Spoof Surface Plasmon Cavity-Waveguide Coupling System

IEEE Transactions on Microwave Theory and Techniques, 2016
Many efforts have been devoted to the design of photonic microcavities and the utilization of them in optical sensing, imaging, optomechanics, lasing, and micromanipulation. Cavities supporting spectrally close multiple resonance modes can favor energy exchange among the modes and the ambient, enabling nontrivial coherent dynamics that are useful in ...
