The Infrastructure, Airspace Systems and Airports Department of the Polytechnic University of Madrid (UPM) and the Computer Science and Automatic Department of the National University of Distance Education (UNED), are developing a theoretical model for the assessment of the multipath effects on GPS receivers, for its direct application on GNSS Reference Stations. This paper presents the results reached so far, in relation to the developed model application for predicting the mentioned multipath effects. These effects have been evaluated theoretically and verified experimentally. Reflection and Diffraction characterisation have been adapted to the nature of the different analysed surfaces; also the evaluation has been performed by simulation of three types of correlator, Standard, Narrow and MEDLL.
