The invention belongs to the field of electronic communication and automatic control, and relates to a method for achieving the positioning of a receiver in a satellite signal blind area through combining a mobile cellular network and a satellite navigation system. The method comprises the steps that the receiver employs two different methods for independently calculating the position coordinates firstly through employing a satellite signal transmitted by a base station: one method is that the receiver deduces the position coordinates at a next moment based on a positioning result at a former moment, and the other method is that the receiver measures the pseudo-distance between the base station and the receiver through employing the satellite signal, and then calculates the position through employing a triangulation location principle; afterwards, the receiver combines the positioning results, obtained through the above two methods, as an observation value, and carries out the filtering of the results through employing a Kalman filtering algorithm, so as to determine the final position coordinates of the a user. The method is low in arrangement cost in actual use, is easy to install, and can obtain higher positioning precision.
