An Integrated Framework for Sensing Radio Frequency Spectrum Attacks on Medical Delivery Drones
, 2020 Drone susceptibility to jamming or spoofing attacks of GPS, RF, Wi-Fi, and operator signals presents a danger to future medical delivery systems. A detection framework capable of sensing attacks on drones could provide the capability for active responses.

Influence of topography and canopy cover on argos satellite telemetry performance
Wildlife Society Bulletin, 2012 Environmental variables can affect performance of global positioning system (GPS) telemetry; however, similar assessments have not been reported for Argos satellite telemetry. We used a stratified random design and linear mixed‐effects models to evaluate

A Markov Chain state transition approach to establishing critical phases for AUV reliability [PDF]
, 2011 The deployment of complex autonomous underwater platforms for marine science comprises a series of sequential steps. Each step is critical to the success of the mission. In this paper we present a state transition approach, in the form of a Markov chain,

Evaluating GPS biologging technology for studying spatial ecology of large constricting snakes
Animal Biotelemetry, 2018 Background GPS telemetry has revolutionized the study of animal spatial ecology in the last two decades. Until recently, it has mainly been deployed on large mammals and birds, but the technology is rapidly becoming miniaturized, and applications in ...

Statistical interaction modeling of bovine herd behaviors [PDF]
, 2011 While there has been interest in modeling the group behavior of herds or flocks, much of this work has focused on simulating their collective spatial motion patterns which have not accounted for individuality in the herd and instead assume a homogenized ...

Testing the functionality and contact error of a GPS‐based wildlife tracking network
Wildlife Society Bulletin, 2013 Telemetry is a fundamentally important tool for studying animal movements. Traditional telemetry systems have provided time‐specific information on locations of individuals; however, recent developments in instruments allow for the tracking of networks ...

Screening GPS telemetry data for locations having unacceptable error
Ecological Informatics, 2015 Abstract Technological improvements in battery life and physical dimensions of Global Positioning System (GPS) telemetry have increased the number of locations one can collect, but due to relatively unimproved GPS accuracy this also increases the number of locations with unacceptable measurement error.
