Assessing GPS Robustness in Presence of Communication Signals

Abstract

A constantly increasing number of new applications are based on wireless communication system integrated with navigation/positioning platforms. The mutual benefits they can obtain from each others are intrinsically related to the interoperability level and to a properly designed coexistence. In this paper a new family of curves, called interference error envelope (IEE), is used to assess the impact of possible interference generated by other systems (e.g. communications) on Global Navigation Satellite System (GNSS) signals. The focus is on the analysis of the GPS C/A code robustness.
