Covers the latest developments in PNT technologies, including integrated satellite navigation,
sensor systems, and civil applications Featuring sixty-four chapters that are divided into …

This paper studies the feasibility and means by which authentication can be overlaid upon
the existing SBAS and GBAS designs. It considers how to achieve the authentication that is …

Due to their weak received signal power, Global Positioning System (GPS) signals are
vulnerable to radio frequency interference. Adaptive beam and null steering of the gain pattern of …

Spoofing attacks are a major threat to civilian GNSS usage given the powerful impact that they
have on a receiver. Many different anti-spoofing techniques have been developed in past …

Due to the ever-growing threat of GPS spoofing, it has become necessary for the aviation
sector to develop an effective means of detection. This article focuses on two complementary …

Adaptive antenna array processing is widely known to provide significant anti-interference
capabilities within a Global Navigation Satellite Systems (GNSS) receiver. A main challenge …

This flimsy was developed to document the work being accomplished by the FAA to assess
alternatives for providing PNT services when GNSS is not available due to RFI.

Reliable radio navigation signals are of extreme importance. Nowadays we rely on Global
Navigation Satellite System (GNSS) related technologies for a range of uses ranging from …

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 of …

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 …
