PROBLEM TO BE SOLVED: To provide a GNSS(Global Navigation Satellite System) positioning device capable of suppressing the deterioration of positioning accuracy in an environment in which there is possibility that a positioning signal receives the influence of a multipath.SOLUTION: A GNSS positioning device includes: a wireless communication device for receiving vehicle reception information including the C/N of a positioning signal that a peripheral vehicle existing in the periphery of an own vehicle has received from a positioning satellite from the peripheral vehicle; a GNSS receiver for receiving the positioning signal transmitted by the positioning satellite; a reception quality acquisition part (S1) for acquiring the C/N of the positioning signal received by the GNSS receiver; a determination part (S3) for determining whether or not the positioning signal corresponding to the C/N acquired by the reception quality acquisition part receives the influence of a multipath on the basis of the comparison of the C/N acquired by the reception quality acquisition part with the C/N included in the vehicle reception information received by the wireless communication device; and positioning arithmetic units (S5, S6) for excluding the positioning signal determined to receive the influence of the multipath by the determination part from the positioning signal received by the GNSS receiver to perform a positioning operation.SELECTED DRAWING: Figure 3 |
