When more than three distances are involved, it may also be called multilateration, for emphasis. The point of interest is often around Earth (geopositioning).
The distances or ranges might be ordinary Euclidean distances (slant ranges) or spherical distances (scaled central angles), as in true-range multilateration; or biased distances (pseudo-ranges), as in pseudo-range multilateration.
