The following graph illustrates how positioning works in a 2D plane. By knowing the distance from three "satellites" (A, B, and C), the unique intersection point defines the exact position. Summary Table: Positioning Methods Data Required Common Use Case Distances from fixed points GPS, Radar, Cell tower location Triangulation Angles from fixed points Land surveying, Navigation (Compass) Multilateration Time Difference of Arrival (TDOA) Locating emergency calls, Aviation
By knowing the baseline distance between two fixed points and measuring the angles to a third point, the can be used to calculate the remaining sides of the triangle and find the coordinates of the target.

Positioning problems in the show typically focus on how to find a point ( ) when given its relationship to other fixed points. : This is the primary method used by GPS satellites. If you know your distance ( ) from three different points ( The following graph illustrates how positioning works in
