论文摘要
许多跑步者使用融合全球定位系统技术的手表来跟踪锻炼。这些设备可以是有价值的培训辅助工具，但它们有局限性。由于几个原因，包括卫星位置的变化，环境因素和制造商做出的设计决策，具有GPS的手表可能会产生位置测量错误。这些可能会导致对覆盖的总距离和运行速度的不正确估计。这项研究检查了几年来，使用重复试验，使用了同一跑步者在同一路线上使用重复试验的三个Garmin跑步手表的准确性。旧的手表，先驱205和先驱220，在穿越路线时显示出相似的准确性。在其距离测量值的真实性和精度方面，发现新一代的手表是一种先驱45s。这可能表明Garmin在与其他类似设备的其他制造商的竞争中，近年来选择了设备小型化和电池寿命优先于精度。
Many runners use watches incorporating Global Positioning System technology to track their workouts. These devices can be valuable training aids, but they have limitations. For several reasons including variations in satellite position, environmental factors, and design decisions made by the manufacturer, GPS-enabled watches can produce position measurement errors. These can result in incorrect estimations of total distance covered as well as running pace. This study examined the accuracy of three Garmin running watches of different technological generations using repetitive trials, over several years, by the same runner over the same route. The older watches, a Forerunner 205 and a Forerunner 220, showed similar accuracy when traversing the route. The newer generation watch, a Forerunner 45S, was found to be significantly less accurate in terms of both the trueness and precision of its distance measurements. This may indicate that Garmin, in competition with other manufacturers of similar devices, has chosen in recent years to prioritize device miniaturization and battery life over accuracy.
