Abstract
Ground stationsreceive any signal transmitted by a geostationary artificial satellite, and store the reception signal together with the reception time thereof. A difference Δt in reception time of a same signal between the ground stationand the ground stationis calculated by performing correlation processing of the reception signal of the ground stationand the reception signal of the ground station. A distance Rbetween the ground stationand the geostationary artificial satelliteis measured by a distance measurement device. A distance Rbetween the ground stationand the geostationary artificial satelliteis calculated on the basis of the distance Robtained by measurement and the difference Δt in reception times, as obtained by correlation processing.
