In which field would you use a global positioning system?

Using a global positioning system (GPS) is fundamentally tied to navigational tools, making that the most fitting context for its application. GPS technology allows individuals to determine their precise location anywhere on Earth by receiving signals from satellites. This functionality is critical for various forms of navigation, whether it be in vehicles, for aviation, or even maritime activities. It enables real-time tracking and routing, making travels more efficient and safe by providing accurate directions and information about surrounding environments.

Other fields, such as mapping planetary surfaces or studying soil erosion, may employ GPS technology for specific tasks, but their primary focus is not navigation. Weather forecasting relies heavily on data collection and modeling rather than on precise location tracking offered by GPS. Thus, while GPS may have applications across these fields, its core purpose and utilization lie predominantly in navigating various terrains and routes.
