Effects of radio‐collar position and orientation on GPS radio‐collar performance, and the implications of PDOP in data screening
Abstract
Summary: Global positioning system (GPS) radio‐telemetry has become an important wildlife research technique worldwide. However, understanding, quantifying and managing error and bias in raw GPS radio‐telemetry data sets requires much more work. In particular, error and bias resulting from position (angle away from vertical) and orientation (compass direction) of GPS radio‐collars on free‐ranging animals is currently unknown. We tested the effects of collar position and orientation on GPS radio‐collar performance using five stationary GPS radio‐collars. We also investigated the use of positional dilution of precision (PDOP) as a method for screening data with high location errors. Orientation had no statistical effect on fix rates or location errors. The biggest source of variation was attributed to collar position, which resulted in significantly lower performance at angles below 90° from vertical. PDOP‐based screening was effective and can be used to lower location error, but the trade‐off between higher location accuracy and data loss (potentially leading to new bias) must be assessed. Synthesis and applications. The results of this study refine our understanding of error and bias in GPS radio‐telemetry data. We suggest that collar orientation can safely be disregarded, whereas radio‐collar position remains a large potential source of error and bias. This finding has major implications regarding animal activity and GPS radio‐telemetry research. Researchers need to quantify and account for biases resulting from animals moving through heterogeneous terrain and habitats.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
