Title:
INTERFERENCE POWER ESTIMATION METHOD, INTERFERENCE POWER ESTIMATION DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/066470
Kind Code:
A1
Abstract:
A projection unit (12) of an interference power estimation device (1) projects an orbit of a satellite on a map which represents the ground surface. A range acquisition unit (13) defines a plurality of ranges on the map so as to include the projected orbit. An altitude calculation unit (14) calculates the altitude of the orbit of the satellite within each of the ranges. An individual range interference calculation unit (16) calculates, in each of the ranges, interference power between the satellite at a position defined on the basis of the latitude and the longitude in the range and the altitude calculated for the range and a wireless station installed on the ground surface. An estimation result calculation unit (17) selects, as an estimation result, a maximum value of the interference power calculated for each of the ranges.
