Abstract

The Global Navigation Satellite System (GNSS) is the standard generic term for satellite navigation systems that provide global coverage and it includes GPS, GLONASS, Galileo and other regional satellite navigational systems. The use of simulator for performing different kinds of test is a practice largely used that provides many advantages in different navigation systems thanks to the possibility of performing tests under controlled and repeatable conditions in a secure laboratory. The use of GPS simulation is largely used for testing GPS receivers. This paper presents a GNSS simulator for automotive applications, in particular the software used is GPS-SDR-SIM, an open source simulator written in C language and it proposes a simulator improvement providing the implementation of the Troposphere Collins model in order to improve the accuracy of the simulation experiments.
