GPS test platforms. We deployed seven GPS test platforms in ENP to quantify habitat-driven bias in fix rate and measure GPS location accuracy and precision. Tag bodies were mounted inside a cutout in a PVC pipe (left) and then covered with freezer gel packs and duct tape (right) so that only the antenna protruded to simulate implantation under a python’s skin
