Open-source technology has been increasingly used for developing low-cost animal-borne bio-loggers; however, a gap remains for a bio-logger that records both inertial movement and GPS positions. We address this need with the Tapered Wings Logger (TWLogger), an archival bio-logger that records high-resolution (e.g. 50 Hz) tri-axial accelerometry and magnetometry, temperature and GPS. The TWLogger can be built for 90 USD, accepts user-defined sampling parameters, and with a 500 mA h battery weighs 25 g. We provide publicly available build instructions and custom analysis scripts. Bench tests recorded 50 Hz inertial movement and 2 min GPS for 31.8±2.2 h (mean±s.d., =6) with GPS accuracy within 10.9±13.6 m. Field deployments on a medium-sized bird of prey in the wild achieved similar results (=13). The customizable TWLogger has wide-ranging application across systems and thus offers a practical solution for eco-physiology applications.
开源技术越来越多地用于开发低成本的动物携带式生物记录器；然而，对于既能记录惯性运动又能记录 GPS 位置的生物记录器，仍存在一个空白。我们通过锥形翼记录器（TWLogger）解决了这一需求，这是一种可记录高分辨率（例如 50 Hz）三轴加速度计和磁力计、温度和 GPS 的档案式生物记录器。TWLogger 的成本为 90 美元，可以接受用户定义的采样参数，并且带有 500 mA h 电池，重量为 25 克。我们提供了公开可用的构建说明和定制的分析脚本。台架测试记录了 50 Hz 的惯性运动和 2 分钟的 GPS，持续时间为 31.8±2.2 h（平均值±标准差，n=6），GPS 精度在 10.9±13.6 m 以内。在野外对一种中等体型的猛禽进行的实地部署也取得了类似的结果（n=13）。可定制的 TWLogger 在系统中有广泛的应用，因此为生态生理学应用提供了一个实用的解决方案。
