## trilateration

(ˌtraɪlætəˈreɪʃən)
n
(Surveying) a method of surveying in which a whole area is divided into triangles, the sides of which are measured, usually by electromagnetic distance measuring for geodetic control or by chain survey for a detailed survey

They basically work like a collection of satellites with which we leverage trilateration to determine the position of a smartphone.
The most basic algorithm used for positioning based on range estimation is trilateration .
In the original DV-Hop algorithm, the trilateration algorithm or the least squares method is applied to solve the multi-objective optimization problem and transform the location information for unknown nodes to coordinates.
The majority of localization algorithms assume a dense network trilateration or multilateration can be organized.
In this Performance Task, there are four "explorations," the first of which helps students understand the deductive logic of trilateration.
Xia and Chen  propose a TDOA-based localization scheme with mobile anchors in which the sensor nodes perform trilateration to estimate their positions.
Using the photo trilateration procedure, air coordinates were obtained for near vertical photo frames captured by a motorised 70mm Vinten reconnaissance camera.
Many localization algorithms first use a ranging technique to estimate the Euclidean distances between nodes, and then use the least-squares trilateration (LST) algorithm to determine the locations of sensor nodes by these estimated distances .
Your location will not be able to be determined via trilateration or any other method, keeping your position private and secure.
The basic techniques employed for location calculation are: Trilateration Triangulation Maximum Likelihood (ML)
It should be emphasized that the solutions are not exactly the same as in case of classical trilateration, since the computations are performed on a basis of double differences, using real satellite phase observations as reference.
Given the locations of the anchors and the correction factor, a node is then able to perform trilateration to estimate its own location.
