“…There are a variety methods by which this can be done, such as some form of triangulation or the overlapping of sensing ranges [1][2][3][4]. This concept is of course similar to approaches often used in vision-based navigation where, using SIFT [5] for example, landmarks are identified in a room and tracked.…”

In the field of mobile robot navigation, active beacons are a well researched tool to provide an infrastructure for guidance systems. One drawback to the use of active beacons is that their layout is sometimes arbitrary. Moreover, it is often determined solely by the researcher's preference or experience. While this is occasionally the easiest way to produce results, it is a significant roadblock to the general use of these systems in practical applications, as the layout for any installation must be evaluated by an expert user. In an attempt to formalize the placement of nodes in such a system, we have developed a straightforward approach for the placement of nodes. This approach has also been applied to a software tool which would allow even a novice user to generate layouts for their applications.

Modern systems and devices, including unmanned aerial systems (UASs), autonomous vehicles, and other unmanned and autonomous systems, commonly rely on the Global Positioning System (GPS) for positioning, navigation, and timing (PNT). Cellular mobile devices rely on GPS for PNT and location-based services. Many of these systems cannot function correctly without GPS; however, GPS signals are susceptible to a wide variety of signal-related disruptions and cyberattacks. GPS threat detection and mitigation have received significant attention recently. There are many surveys and systematic reviews in the literature related to GPS security; however, many existing reviews only briefly discuss GPS security within a larger discussion of cybersecurity. Other reviews focus on niche topics related to GPS security. There are no existing comprehensive reviews of GPS security issues in the literature. This paper fills that gap by providing a comprehensive treatment of GPS security, with an emphasis on UAS applications. This paper provides an overview of the threats to GPS and the state-of-the-art techniques for attack detection and countermeasures. Detection and mitigation approaches are categorized, and the strengths and weaknesses of existing approaches are identified. This paper also provides a comprehensive overview of the state-of-the-art on alternative positioning and navigation techniques in GPS-disrupted environments, discussing the strengths and weaknesses of existing approaches. Finally, this paper identifies gaps in existing research and future research directions.
