Trilateration

In geometry, trilateration is the process of determining absolute or relative locations of points by measurement of distances, using the geometry of circles, spheres or triangles. In addition to its interest as a geometric problem, trilateration does have practical applications in surveying and navigation, including global positioning systems (GPS). In contrast to triangulation, it does not involve the measurement of angles.In two-dimensional geometry, it is known that if a point lies on two circles, then the circle centers and the two radii provide sufficient information to narrow the possible locations down to two.

  • Aruba Networks Enables “Blue-Dot” Indoor Navigation With Beacons

    … successfully accomplished in the past, partly because there haven’t been enough beacons deployed in locations and because their low power system — beacons use Bluetooth Low Energy to minimize battery drain — hasn’t created strong enough or stable-enough signals to manage “blue dot” navigation. (As an aside Indoor Atlas enables indoor, blue-dot…
