The practice of verifying results using multiple tests. In geometric terms, an unknown third point can be determined with one known side and two known angles
Lab medicine A popular term for the use of two or more tests to evaluate one condition

Oncology A method for determining the exact position of a breast lesion localized by a guide wire of a lesion of the breast, based on 3 parameters: position, depth of penetration, wire angle. See Guided wire open biopsy. Cf Stereotactic biopsy.

If the leaked location is coarse-grained, the risk of data leakage is medium because the attacker needs to probe more data and use trilateration positioning to get people's relatively precise locations.
When a User Node (UN) enters an area, where it can obtain at least 3 ranging measurements to 3 distinct NN of a LRF, a trilateration algorithm can be performed and a solution for its relative position inside LRF can be obtained.
In parallel, selected sensor nodes calculate target location locally using trilateration algorithm.
The Angle of arrival will be used for the Angle Measurement(AOA).so this Method is best when compared with the Trilateration scheme where node position will be measured from the multiple reference points by using the TOA(Time of arrival).
Finally, students learn how communications between multiple satellites and a ground-based, handheld unit use the r x t = d relationship along with trilateration to lock in a location.
The LIS used in this paper is called i-Tracer, it is developed by least-squares trilateration (LST) algorithm [10].
ML Mulilateration technique is employed in place of Trilateration if the distance measurements are noisy as Trilateration cannot give accurate results in such conditions.
Given the locations of the anchors and the correction factor, a node is then able to perform trilateration to estimate its own location.
Another interesting thing--GPS operates through a system of satellites that transmit radio signals to the user's receiver where a trilateration is performed to determine a position based on the time difference of arrival of those signals.
When the distance from the moving node to at least three fixed nodes is known, the location of moving node can be calculated with trilateration [10].
In a matter of seconds, through the use of complex trilateration, your exact location on or around earth is pinpointed.
The methods to create the micro-network are triangulation, trilateration, levelling or trigonometric high.
