GPS telemetry of forest elephants in Central Africa: results of a preliminary study
African Journal of Ecology, 2001AbstractFew data exist on the ranging behaviour of forest elephants. A feasibility study on the use of GPS telemetry as a tool to study ranging, seasonal movements and distribution was implemented in the Dzanga‐Sangha and Nouabalé‐Ndoki National Parks Complex of Central African Republic and Congo. The study consisted of two parts – a thorough hand‐held

The accuracy of GPS for wildlife telemetry and habitat mapping [PDF]
Journal of Applied Ecology, 2001 Summary Decision support tools used for vegetation management require accurate information on the spatial array of different plant communities and a herbivore’s grazing location. We tested the accuracy and precision of locations derived using the satellite navigation global positioning system (GPS).

An Investigation of GPS-Denied Navigation Using Airborne Radar Telemetry
2020 IEEE/ION Position, Location and Navigation Symposium (PLANS), 2020A supplementary sensor being explored in the field of GPS-denied navigation is Synthetic Aperture Radar (SAR) with its resulting images. In contrast to passive, camera-based methods, SAR provides illumination of a scene, direct measurement of range, and can operate day and night or through incliment weather.

Quantification and Accuracy of Activity Data Measured with VHF and GPS Telemetry
Wildlife Society Bulletin, 2006Quantifying activity budgets and determining the accuracy of behavioral data obtained by telemetry is essential to understand the behavior of animals that are difficult to observe. We fitted 8 captive white-tailed deer (Odocoileus virginianus) with VHF or GPS collars to determine the accuracy of VHF variable-pulse sensors and GPS dual-axis sensors and ...

Accuracy of GPS Telemetry Collar Locations with Differential Correction
The Journal of Wildlife Management, 1997Global Positioning System (GPS) units in telemetry collars provide an unbiased and precise estimate of animal locations. Under ideal conditions at least 50% of locations are expected to be within 40 m in uncorrected mode GPS, and within 5 m in differential mode GPS.

Optimizing the positioning of wildlife crossing structures using GPS telemetry
Journal of Applied Ecology, 2018Abstract Development of transportation corridors has accelerated globally, with infrastructure projects being implemented across remote ecosystems, particularly in the tropics. Such developments can have negative impacts on wildlife and their ecosystems.

Wildlife Society Bulletin, 2017 ABSTRACT Studies using global positioning system (GPS) telemetry rarely result in 100% fix success rates (FSR), which may bias datasets because data loss is systematic rather than a random process. Previous spatially explicit models developed to correct for sampling bias
