Recently, several global navigation satellite systems (GNSS) emerged following the
transformative technology impact of the first GNSS-US global positioning system (GPS). The …

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 …

One of the main vulnerabilities of GNSS receivers is their exposure to intentional or
unintentional jamming signals, which could even cause service unavailability. Several …

High attenuation, blockage and severe multipath fading in urban environments, under dense
canopy or jamming attacks degrade accuracy, continuity, availability and integrity of GNSS …

Radio frequency interference (RFI) is causing performance loss in microwave radiometry,
radio astronomy, and satellite communications. As the number of interferers increases, the …

Signal acquisition has become the performance bottleneck of global navigation satellite
systems (GNSS) receivers in harsh interference environments due to its low sensitivity. In …

The Global Positioning System (GPS), with its accurate positioning and timing information,
has become a commonly used navigation instrument for many applications. However, it is …

Array processing algorithms such as direction of arrival (DOA) estimation, deterministic
beamforming and null-steering as well as spoofer detection and mitigation are known to be …

The use of antenna arrays in Global Navigation Satellite System (GNSS) applications is
gaining significant attention due to its superior capability to suppress both narrowband and …

The Galileo E6 band operates at a nonprimary frequency band within the L‐band. This
presents challenging situations in the vicinity of other, legitimate, radiolocation services. This …
