Abstract:	In order to provide a technical support to the deployment of sensor station of the new Radio-Navigation Satellite System (RNSS) Galileo, compatibility with pulsed interference sources has to be considered. Compatibility between Galileo bands and existing Aeronautical Radio-Navigation Systems (ARNS) or Airport Surveillance Radars (ASR) has already been addressed for aeronautical users, in dedicated RTCA documentations. But a specific complementary study has to be carried out for ground receivers, such as Galileo Sensor Stations (GSS). This paper aims at assessing the impact of such EMI on GSS performances, when deployed into previously designed operational scenarios. This assessment is carried out accounting for blanking device mitigation efficiency. Interferers are first inventoried, and their impact assessed on a case by case basis. The source data base thus constituted, complemented by existing literature, is then used to define multiple interferers scenarios. These scenarios are intended to be considered for GSS site selection (issue of recommendations regarding pulsed interference sources) and to drive GSS design. This analysis is carried in the framework of a work plan, on-going at Galileo Mission Segment level to contribute to site acceptance criteria definition.
