In 3D Euclidean space, the position of a point is uniquely determined by its distance from three other (distinct, non-colinear) points (mostly; in some cases there may be two solutions). Trilateration is the process of finding a point from three of these distance/point pairs - strictly speaking, this is "true range" trilateration (or, more generally, multilateration), and the more widely used pseudo-range trilateration (multilateration) uses four distances instead.

[[GPS]], in [[ComputerCraft]] and otherwise, is based on this process, though ComputerCraft GPS is free of almost all noise and sources of error and thus uses much simpler algorithms and can achieve near-perfect accuracy easily.
