Unmanned aircraft systems (UAS) generally use Global Navigation Satellite System (GNSS) measurements to estimate their state (position and orientation) for outdoor navigation. However, in urban environments, GNSS pseudorange measurements contain bias

Reliably assessing the error in an estimated vehicle position is integral for ensuring the vehicle’s safety in urban environments. Many existing approaches use GNSS measurements to characterize protection levels (PLs) as probabilistic upper bounds

Secure antenna polarization modulation, or SAPM, is a method for increasing security at the physical layer via spatial signal distortion. We derive its expected performance in additive white Gaussian noise (AWGN) channels with the goals of establishi

Real-time monitoring of a wide-area power grid network has become feasible with time-synchronized Phasor Measurement Units (PMUs). PMUs use GPS signals for time synchronization and are susceptible to GPS Spoofing Attacks (GSAs) since civilian GPS sig
