We introduce a novel ultra-low power system for tracking animal movements over long periods with an unprecedented high-temporal-resolution. The localization principle is based on the detection of cellular base stations using a miniaturized software-defined radio, weighing 2.0 g, including the battery, and having a size equivalent to two stacked 1-euro cent coins. Therefore, the system is small and lightweight enough to be deployed on small, wide-ranging, or migrating animals, such as European bats, for movement analysis with an unprecedented spatiotemporal resolution. The position estimation relies on a post-processing probabilistic RF pattern-matching method based on the acquired base stations and power levels. In several field tests, the system has been successfully verified, and a run-time of close to one year has been demonstrated.
我们介绍了一种新颖的超低功耗系统，用于长时间跟踪动物的运动，具有前所未有的高时间分辨率。定位原理基于使用小型软件定义无线电检测蜂窝基站，该无线电重量为 2.0 克，包括电池，大小相当于两个堆叠的 1 欧元硬币。因此，该系统足够小且轻巧，可以部署在小型、广泛或迁移的动物（例如欧洲蝙蝠）上，以便以前所未有的时空分辨率进行运动分析。位置估计依赖于基于所获取基站和功率水平的后处理概率射频模式匹配方法。在几次现场测试中，该系统已成功验证，并展示了接近一年的运行时间。
