Assessing Repeatable Accuracy Potential of LoRa: A Navigation Approach

open access: yesIEEE Access, 2022
Two main classes of radio navigation systems are satellite and ground-based systems. Examples of such systems are eLoran deployed as a terrestrial system, and BeiDou, Galileo, GPS and Quasi-Zenith Satellite System (QZSS) deployed as satellite Navigation ...

Response of horizontal dilution of precision (HDOP).

open access: yes, 2018
HDOP values in different habitat types and topographic levels are plotted against number of fixes in the Central Highlands. Predictions are from linear models and dots represent raw data. Shaded areas indicate 95% confidence interval.

Moving wildlife tracking forward under forested conditions with the SWIFT GPS algorithm

open access: yesAnimal Biotelemetry, 2022
The remote collection of animal location data has proliferated in recent decades, and higher-frequency data are increasingly available with battery-saving optimisations such as ‘snapshot’ algorithms that acquire GPS satellite data and post-process ...

A New Array Pseudolites Technology for High Precision Indoor Positioning

open access: yesIEEE Access, 2019
Global Satellite Navigation System (GNSS) can't provide normal location service in the indoor environment because the signal can be blocked by buildings. The pseudolites system can supplement GNSS, especially in the indoor environments.

The effect of simulated intergroup encounters on movement patterns and home range use in banded mongooses

open access: yesWildlife Biology, Volume 2026, Issue 3, May 2026.
Intergroup conflicts have a wide range of impacts, including affecting movement and ranging patterns. Previous studies found contrasting movement responses to intergroup conflicts, but no explanation for these differences has been suggested. However, these can be broadly grouped into ‘conflict avoidance' responses: avoiding areas close to the fight ...

Short‐term effects of wildlife rehabilitation disappear over time in the wild: A case study on Spanish imperial eagles

open access: yesConservation Science and Practice, Volume 8, Issue 5, May 2026.
We assessed the effectiveness of Wildlife Recovery Centers by comparing dispersal behavior of rehabilitated and wild Spanish imperial eagles using GPS tracking. Rehabilitated individuals initially moved shorter distances, rested more, and hunted less than wild controls, but these differences declined over time and ultimately disappeared.

So close yet so far: Movement patterns of livestock guarding dogs in a shared landscape in Romania

open access: yesEcological Solutions and Evidence, Volume 7, Issue 2, April–June 2026.
We used GPS collars to track 36 livestock guarding dogs (LGDs) from 11 sheep flocks in the Romanian Carpathians to assess how closely they remained with their sheep and how often they roamed in a landscape shared with people and large carnivores. Overall, LGDs were attentive, typically staying within 100 m of sheep at night and 200 m during the day ...

Simulation of GNSS Dilution of Precision for Automated Mobility Along the MODI Project Road Corridor Using High-Resolution Digital Surface Models

open access: yesGeomatics
Horizontal dilution of precision (HDOP) is a widely used quality indicator of Global Navigation Satellite System (GNSS) positioning, considering only satellite geometry.
