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…
