Once epicentral distances have been calculated from at least three seismographic measuring stations, it is a simple matter to find out where the epicenter was located using trilateration.

MBS is built on principles similar to GPS transmitting precisely timed signals from a network of wide-area beacons enabling receivers to use trilateration techniques to determine their precise location.
23.
However, the accuracy of BlackBerry trilateration is less than that of GPS due to a number of factors, including cell tower blockage by large buildings, mountains, or distance.

MBS is built on principles similar to GPS, transmitting precisely timed signals from a network of wide-area beacons enabling receivers to use trilateration techniques to determine their precise location.
25.
The search can be sped up by using a trilateration procedure that takes ( guessed ) positions for four speakers as input although you may be unlucky if these four are coplanar.
26.
A feature of the newer models of the BlackBerry is their ability to quickly track the user's current location through trilateration without the use of GPS, thus saving battery life and time.
27.
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.
28.
The accuracy of network-based techniques varies, with cell identification as the least accurate and triangulation as moderately accurate, and newer " advanced forward link trilateration " timing methods as the most accurate.
29.
It is also found that the dimensional structure and characteristics of phase space can naturally neutralize the bias of positioning ( based on techniques such as triangulation or trilateration ) caused by reasons such as multipath.
30.
Several such measurements can be made at the same time to different satellites, allowing a continual fix to be generated in real time using an adapted version of trilateration : see GNSS positioning calculation for details.
