新的颈圈设计应在受控环境中进行测试，以确定精度是否与当前可用的技术相当。我们评估了一种新的全球定位系统（GPS）项圈白尾鹿（Odocoileus virginianus），以确定位置精度是否与以前的文献，以及是否有领动物或植被特征的行为影响位置精度。我们在密西西比州立大学的封闭式野生动物研究和教育设施中捕获了5只雄性白尾鹿。我们从固定的观察站观察鹿，当GPS项圈试图获取位置时，我们记录了鹿的行为、头部位置和位置。全球定位系统项圈收集了85%的尝试位置。位置误差不受行为的影响（即，卧床、移动或站立）或头部位置（即，下降、混合、上升，P>0.05）。GPS项圈获得定位的能力受行为的影响（P<0.001），但不受头部位置的影响（P=0.099）。植被特征（即，断面积、树冠覆盖率和到最近树木的距离）并不影响GPS项圈获得定位的能力，尽管圈养鹿设施内的植被特征范围很窄。这种新的GPS项圈设计可以经济有效地用于获得动物的位置，具有很高的准确性和精度，操作员或设备误差很小。
New collar designs should be tested in controlled settings to determine whether accuracy is comparable to currently available technology. We evaluated a new Global Positioning System (GPS) collar for white-tailed deer (Odocoileus virginianus) to determine whether positional accuracy was comparable to previous literature and whether behavior of collared animals or vegetation characteristics affected positional accuracy. We collared 5 male white-tailed deer at the enclosed Wildlife Research and Education Facility at Mississippi State University. We observed deer from a fixed observation stand. We recorded behavior, head position, and location of deer when GPS collars attempted to acquire a location. Global Positioning System collars collected locations on 85% of the attempts. Positional error was not affected by behavior (i.e., bedded, moving, or standing) or head position (i.e., down, mixed, up, P>0.05). Ability of the GPS collar to acquire a fix was affected by behavior (P<0.001), but not by head position (P=0.099). Vegetation characteristics (i.e., basal area, canopy coverage, and distance to nearest tree) did not affect ability of GPS collars to acquire a fix, although there was a narrow range of vegetation characteristics within the captive deer facility. This new GPS collar design can be used cost-effectively to obtain animal locations with great accuracy and precision and with little operator or equipment error.
