1. A method of determining topographical interference with a guided missile to be performed by an apparatus for determining topographical interference with a guided missile, the method comprising:
obtaining pre-calculated expected trajectory information of a guided missile;
extracting topographic elevations with respect to a topography corresponding to the pre-calculated expected trajectory information from stored topographical information; and
determining presence or absence of topographical interference with the guided missile based on a plurality of bottom trajectory elevation values in the pre-calculated expected trajectory information and a plurality of topographic elevation values of the topographic elevations corresponding to the plurality of bottom trajectory elevation values,
wherein the pre-calculated expected trajectory information includes a top trajectory, a bottom trajectory, a left trajectory, and a right trajectory with respect to a launch direction of the guided missile, calculated based on one or more error factors for the guided missile, and
wherein the one or more error factors comprise manufacturing error values with respect to at least one of a weight, center of gravity, a thrust, or a moment of inertia of the guided missile.
