全球定位系统（GPS）似乎将取代传统的地图和指南针，用于军事和民用领域的导航任务。然而，我们可能会问GPS是否比传统方法具有真正的性能优势。我们提出了一项探索性研究，使用航路点绘图任务来比较标准磁罗盘与军用GPS单元，适用于专家和非专业导航员。虽然设置GPS单元的时间通常更长，但一旦导航开始，GPS比指南针更有效。对于中长期任务，这意味着GPS可以提供显著的性能优势，尽管指南针在较短的任务中仍然优越。除了性能时间外，在使用指南针时发生了更多的错误和更严重的错误。总的来说，GPS提供了一些明显的优势，特别是对于非专业用户。尽管如此，在使用GPS技术时，对认知地图发展的担忧仍然存在。
The Global Positioning System (GPS) looks set to replace the traditional map and compass for navigation tasks in military and civil domains. However, we may ask whether GPS has a real performance advantage over traditional methods. We present an exploratory study using a waypoint-plotting task to compare the standard magnetic compass against a military GPS unit, for both expert and non-expert navigators. Whilst performance times were generally longer in setting up the GPS unit, once navigation was underway the GPS was more efficient than the compass. For medium- to long-term missions, this means that GPS could offer significant performance benefits, although the compass remains superior for shorter missions. Notwithstanding the performance times, significantly more errors, and more serious errors, occurred when using the compass. Overall, then, the GPS offers some clear advantages, especially for non-expert users. Nonetheless, concerns over the development of cognitive maps remain when using GPS technologies.
