An open-source hardware GPS data logger for wildlife radio-telemetry studies: A case study using Eastern box turtles

HardwareX, 2018
Global Positioning System (GPS) telemetry technology has been a boon to animal spatial ecology studies. Oftentimes, the main limitation to widespread application of this technology is the cost, which can dictate the number of individuals outfitted with ...

Assessing performance of Bayesian state-space models fit to Argos Satellite telemetry locations processed with Kalman Filtering [PDF]

, 2014
Argos recently implemented a new algorithm to calculate locations of satellite-tracked animals that uses a Kalman filter (KF). The KF algorithm is reported to increase the number and accuracy of estimated positions over the traditional Least Squares (LS)

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 ...

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 ...

Using a drifting GPS-Argos satellite buoy as a method for detecting acoustic-tagged fish offshore in an ancient lake

Animal Biotelemetry, 2023
Background Telemetry methods that allow low-cost, offshore tracking are required for the effective conservation and sustainable use of migratory fish in large lakes with vast and deep offshore areas.

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.

Evaluating the efficacy of using GPS satellite transmitters to assess movement of bigheaded carp in a riverine system

Ecological Solutions and Evidence, 2023
We have evaluated the feasibility of using GPS satellite transmitters on invasive bigheaded carp species, silver carp and bighead carp, that could determine patterns of movement, identify potential feeding and spawning areas, and inform a comprehensive ...

A low-cost GPS GSM/GPRS telemetry system: performance in stationary field tests and preliminary data on wild otters (Lutra lutra).

PLoS ONE, 2012
BackgroundDespite the increasing worldwide use of global positioning system (GPS) telemetry in wildlife research, it has never been tested on any freshwater diving animal or in the peculiar conditions of the riparian habitat, despite this latter being ...
