The invention provides a method for selecting receiving stations of a multi-point positioning system, which comprises the following steps: measuring included angles between each two adjacent receiving stations relative to a monitored target; selecting two receiving stations between which a minimum included angle is formed as two stations to be tested; and deleting one of the two stations to be tested, so that the absolute value of the D-value between an optimal included angle theta and an included angle between the other station to be tested and a station adjacent to the other station to be tested is smaller, wherein theta is equal to 2 pi/K, and K refers to the number of the selected receiving stations; and repeating the steps until the number of the remaining included angle is K. By using the method of the invention, receiving stations in appropriate umber can quickly be selected out, thereby reducing the number of the receiving stations participating in calculation on the premise of guaranteeing the positioning accuracy, and thus reducing the calculated amount and the information redundancy.
