Trilateration and triangulation

Find out about how triangulation and trilateration can be used for indoor positioning.

Trilateration is a method used to determine the position of objects, for example beacons, via distance measurement. Triangulation additionally takes the angle into account. Since GPS isn’t available in buildings, trilateration and triangulation are used for measurement, positioning and navigation there. For displaying objects in 2D, 3 beacons are necessary, for 3D it’s 4.
