The variations of station coordinates deduced from Doppler observations with the use of a single point positioning method based on a precise ephemeris are estimated according to different models and softwares. An identical set of Doppler observations produces station coordinates whose coherence is generally better than 1 m. However, greater differences of 1.5 or 3 m can exceptionally be detected. Apart from the incoherence caused by the differences of models and criteria of data rejection, the reproducibility of Doppler results depends also, through the ephemeris used, on the epoch of measurements. From consecutive periods of 10 days of observations performed on the same site and analyzed with the precise ephemeris computed by D.M.A., a set of station coordinates with a scatter of less than 1 m results. To keep the results near their true value it is also necessary to apply the model to a set of data having as characteristics a good balance between N-S and S-N passes, an approximate knowledge of the true meteorological parameters and at least 40 passes.
