A Method to Assess Robustness of GPS CA Code in Presence of CW Interferences

Abstract EN

Navigation/positioning platforms integrated with wireless communication systems are being used in a rapidly growing number of new applications.

The mutual benefits they can obtain from each other 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 due to other systems (e.g., communications) transmitting in close bandwidths to Global Navigation Satellite System (GNSS) signals.

The focus is on the analysis of the GPS C/A code robustness against Continuous Wave (CW) interference.
