Comparing acoustic and satellite telemetry: an analysis quantifying the space use of Chelonia mydas in Bimini, Bahamas [PDF]

Royal Society Open Science
Passive acoustic and Argos satellite telemetry are common methods for tracking marine species and are often used similarly to quantify space use. However, data-driven comparisons of these methods and their associated ecological inferences are limited. To

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

Integrating Beach Monitoring and Satellite Telemetry to Estimate Loggerhead Clutch Frequency in Brazil [PDF]

Animals
Accurate clutch-frequency estimates are essential for assessing population abundance and reproductive output in sea turtles. Traditional nighttime beach-monitoring approaches, however, often underestimate clutch frequency by missing nesting events ...

Small-Satellite System Fault Diagnosis via a Temporal–Spatial 3D-CNN with Imbalanced-Aware Training [PDF]

Sensors
Reliable onboard fault detection and diagnosis (FDD) is essential for autonomous small-satellite constellation operations. The satellite telemetry streams are typically high-dimensional, strongly time-correlated, and severely imbalanced.
