Final answer:
The system that accurately determines the precise location of something on Earth is called the Global Positioning System (GPS).
Step-by-step explanation:
The system that accurately determines the precise location of something on Earth is called the Global Positioning System (GPS).
GPS relies on an array of 24 satellites orbiting the Earth, and at least 4 of them are visible from any spot on Earth. Each satellite carries a precise atomic clock. Your GPS receiver detects the signals from those satellites that are overhead and calculates your position based on the time that it has taken those signals to reach you.
Another common system for expressing absolute location is the grid geographic coordinate system, which uses lines of latitude and longitude. This system divides the Earth's surface into a grid, and each location on that grid can easily be found using its latitude and longitude coordinate.
