Trilateration

Trilateration is a method used to determine a precise location by measuring distances from known points. Imagine you have three landmarks with known positions. By measuring how far you are from each landmark, you can draw circles around them representing those distances. The exact point where all three circles intersect is your location. This technique is commonly used in GPS technology, where satellites serve as the known points, allowing devices to pinpoint their position on Earth accurately. It's a fundamental principle in navigation, surveying, and various fields requiring location data.
