GPS is critical to which of the following infrastructures?

GPS, or Global Positioning System, is an essential technology in aviation due to its role in navigation and flight safety. In aviation, GPS allows pilots and air traffic controllers to accurately determine the position of an aircraft in real-time, which is crucial for flight planning, route navigation, and landing approaches. The precise positioning capabilities of GPS enhance situational awareness and contribute to the efficient management of air traffic, helping to prevent collisions and ensure safe operations in increasingly busy airspaces.

While other sectors like medical services, retail, and agriculture do utilize GPS technology for various functions—such as tracking deliveries in retail or guiding farm equipment in agriculture—the aviation industry relies heavily on GPS for the safe and effective operation of flights. The dependent nature of aviation on accurate, reliable positioning makes it the most critical infrastructure for GPS technology.
