对于此项目，我选择构建一个工具来跟踪全球定位系统(GPS)路标点(waypoint)和计算到前一个或后一个路标点的距离。

For this project, I chose to build a tool to track a series of global positioning system (GPS) waypoints and compute things like distance to the previous or next waypoint.

说句题外话，像“GPS”(即“全球定位系统”——译者注)这样的技术倒的确可以通过三角测量的卫星定位进行远程跟踪，比如说跟踪某个坐在车里的人。

As an aside, a technology such as GPS can in fact track a thing or, say a person in a vehicle, remotely from far away, by triangulating off of satellites.

装有全球定位系统的照相机可对阿富汗偏远地区的灌溉基础设施建设进度进行跟踪。

GPS cameras track progress on irrigation infrastructure in hard-to-reach areas of Afghanistan.
