The invention provides a multi-antenna ultrashort base line positioning monitoring method and device and a storage medium. The method comprises the steps of receiving a satellite signal by a pluralityof receivers arranged in advance, taking arbitrary one of receivers as a reference station, obtaining original observation data of the reference station, and calculating to obtain carrier phase differential correction and pseudo-range differential correction according to an accurate position of the reference station in the original observation data; obtaining antenna coordinate of each receiver according to the differential correction and antenna position observation data of each receiver; rapidly switching the reference station to obtain relative positions among receivers to achieve the purpose of mutual monitoring; and positioning a target point according to the antenna location position of each receiver. The plurality of receivers are arranged in different directions, the carrier phasedifferential correction i
