PROBLEM TO BE SOLVED: To reduce the effect of a multipath and to improve the measurement accuracy. SOLUTION: This GNSS reception system, performing a geolocation operation based on a geolocation signal transmitted from a GNSS satellite, includes a plurality of antennas which are so disposed that phase differences arise among direct wave and reflected waves, in a state where the GNSS reception system picks up the geolocation signal from the same GNSS satellite; a pseudo-range calculating part which determines a pseudo-range between the GNSS satellite and the GNSS reception system, using a code contained in the geolocation signal from the same GNSS satellite; a pseudo-range difference calculating part which determines a difference of each pseudo-range; a determining part which determines that the geolocation signal from the GNSS satellite is affected by the multipath, based on the difference; a location estimating part which estimates the location of the GNSS reception system, based on information other than the geolocation signal from the GNSS satellite; and a location information output part which outputs location information estimated by the location estimating part, when the geolocation signal is affected by the multipath.
