Abstract

The modernization of GPS and the launch of the Galileo system along with other constellations, will improve the positioning precision. The aim of this work is to obtain a GNSS simulator data that to test and update the multifrequency algorithms that are being developed nowadays in different research centres. To obtain this objective, it is necessary to study each of the terms included in the GNSS observation equation. The first part of the simulator consists of emulating the ionospheric, tropospheric effect and multipath. This paper is devoted to each of these effects summarizing what it is, such as modeling and the method chosen for its simulation and its subsequent implementation in a MATLAB script. The final simulator will include the other terms in the equation of observation such as satellite orbits, atomic clocks and SBAS systems
