| Sumario: | In the latest years, GPS has showed up to be a powerful tool in both scientific and technological aspects. Most of its applications require the highest precision of the system and to achieve it we must enhance our knowledge of the satellite orbits. In this work we describe the classical method of orbital fit and we analyze the different accelerations that take part in it, showing that the actual accuracy is constrained by the solar radiation pressure effect: this fact is confirmed by the analysis of the residuals or our fit. We discuss the actual methods and propose a new treatment of the problem. In order to reach this stage we studied SPR and we develop the necessary formulae through a detailed analysis of the geometry of the problem. |
