    • A positioning system wherein radio waves from a GPS satellite (4) are received by a reference station (1), the absolute position of which is already known, and a plurality of mobile stations (3) to perform relative positioning among particular stations, thereby determining the positions of the mobile stations (3). At least one of the mobile stations (3) is disposed such that a baseline limit length allowing relative positioning relative to the reference station (1) is exceeded, and the intervals between particular mobile stations (3) are shorter than the baseline limit length allowing relative positioning. Each of the stations (1, 3) is equipped with a GPS receiver (11, 21) that receives the radio waves from the GPS satellite (4), and further equipped with a wireless communication apparatus (12, 22) that transmits/receives data to/from a particular station. There are provided a relative position calculation part (32) for calculating the relative position between the particular stations; and an absolute position calculation part (33) for determining, based on an absolute position of one station that performs a relative positioning, an absolute position of the other station.
