Abstract

A projection unit () of an interference power estimation device () projects an orbit of a satellite onto a map representing a ground surface. A range acquisition unit () determines a plurality of ranges on the map so that the projected orbit is included in the ranges. An altitude calculation unit () calculates an altitude of the orbit of the satellite in each of the ranges. A range interference calculation unit () calculates, for each of the ranges, an interference power between the satellite at a position determined by a latitude and a longitude of the range and the altitude calculated for the range and a radio station installed on the ground surface. An estimation result calculation unit () selects, as an estimation result, a maximum value among the interference powers calculated for each of the ranges.
