Triangulation

Definition

Triangulation is a method used in various fields, including navigation and surveying, to determine the location of a point by forming triangles to it from known points. This technique relies on the measurement of angles and distances from multiple reference points to pinpoint a specific position accurately. By using triangulation, systems can improve their precision in determining locations, which is essential for effective sensor fusion and localization.
