Today’s maritime transportation relies on global navigation satellite systems (GNSSs) for accurate navigation. The high-precision GNSS receivers board modern vessels are often considered trustworthy. However, due to technological advances and malicious activities, this assumption is no longer always true. Numerous incidents of tampered signals have been reported. Furthermore, researchers demons...

The authentication of the navigation signals can be considered as contribution system to robustness against spoofing attacks and it is becoming an important requirement for a growing number user communities. GPS Galileo systems are proposing evolutions their civil embed features authentication. For Galileo, Open Service Navigation Message Authentication (OSNMA) integrated in E1 OS signal. GPS, ...

Global navigation satellite systems (GNSS) are integral to aviation navigation and precise landings. It will be fundamental to many other safety of life applications such as railway and autonomous vehicles. To truly protect these systems and maintain safety, we need to not just address nominal hazards but also deliberate threats such as spoofing. Many methods have been proposed to address spoof...

The navigation of small unmanned aerial vehicles (UAVs) mainly depends on global positioning systems (GPSs). However, GPSs are vulnerable to attack by spoofing, which causes the UAVs lose their ability. To address this issue, we propose a deep learning method detect spoofing GPS signals received UAVs. Firstly, describe signal dataset acquisition and preprocessing methods; these include hardware...

Global Positioning System (GPS) spoofing attacks have attracted more attention as one of the most effective GPS attacks. Since signals from an authentic satellite and spoofer undergo different attenuation, captured envelope fake exhibits distinctive transmission characteristics due to short paths. This can be utilized for detection. The existing technique are either computationally too expensiv...

Here, we developed a method for detecting cyber security attacks aimed at spoofing the Global Positioning System (GPS) signal of an Unmanned Aerial Vehicle (UAV). Most methods UAV anomalies indicative attack use machine learning or other such that compare normal behavior with abnormal behavior. Such approaches require large amounts data and significant “training” time to prepare implement syste...
