The invention relates to a method of determining the relative position of a mobile element in relation to the known position of a reference station. The method of calculating the relative position comprises the following steps, namely consisting in: a) selecting a linear combination of satellite transmission frequencies L1 and L2 from a predetermined list comprising at least two linear frequency combinations; b) calculating a precise relative position Pp of the mobile in relation to the reference station from the linear combinations of pseudo-distance corresponding to said linear combination and an estimated position Pe of the mobile element in relation to the reference station; c) selecting the next linear combination from the list if it exists and, in this case, repeating step b) using the precise position Pp as the estimated position; and d) repeating step c) for all of the linear combinations from the list.
