1. Where am I? This is the most fundamental function of GPS. By receiving signals from multiple satellites, GPS devices can calculate your precise latitude, longitude, and altitude, pinpointing your exact location on Earth.
2. How do I get there? GPS not only tells you your current location, but it can also help you navigate to a desired destination. By inputting a destination, GPS devices can calculate routes, provide directions, and estimate travel time. This helps you understand the spatial relationship between your current location and your destination.
