本研究的目的是评估GPS 3300预测欧洲狍活动（进食、移动）和非活动（卧床、站立）行为的准确性。观察到的三只驯服狍的活动与它们项圈上的活动传感器提供的三个变量（每个个体归一化）使用判别分析相关。最好的模型正确地区分了84%的“活跃”时间间隔（定义为鹿至少有30%的时间是活跃的）和97%的不活跃的时间间隔。我们测试了11只野生狍的运动一致性，其中6只生活在森林中，5只生活在开阔的栖息地。不出所料，被确定为不活动（传感器）的野鹿大多是不活动的（GPS位置，831条记录，1096条记录），而已知活动的鹿大多被归类为活动的（758条记录中有493条）。被归类为不活动但移动的记录（24%的不活动记录或35%的移动记录）可以表示短距离位移，错误检测移动或没有颈部运动的移动。被归类为活动但不活动的记录（46%的活动记录，33%的不活动记录）可以代表在没有可检测到的运动的情况下进食一小块。
The aim of this study was to assess the accuracy of GPS 3300 to predict active (feeding, moving) and inactive (bedded, standing) behaviours in European roe deer. Observed activity of three tame roe deer was correlated with the three variables provided by the activity sensors of their collars (normalised for each individual) using discriminant analyses. The best model discriminated correctly 84% of the "active" time intervals (defined as roe deer spending at least 30% of the time active) and 97% of inactive ones. We tested for consistency with movements using 11 wild roe deer, six living in a forest and five in an open habitat. As expected, wild deer identified as inactive (sensors) were mostly immobile (GPS locations, 831 records of 1096), whereas deer known to be moving were mostly classified as active (493 of 758 records). The records classified as inactive but moving (24% of inactive records or 35% of moving records) can indicate short distance displacement, erroneous detection of movement, or moving without neck movements. The records classified as active but immobile (46% of active ones, 33% of immobile ones) can represent feeding on a small patch without detectable movements.
