Within the Directorate European Civil-Military Aviation,  the CNS Evolution Research Unit covers all Agency research and development activities related to Navigation; this includes the Agency’s contribution to Communication, Navigation and Surveillance Support to Deployment and Research projects requiring the expertise available in the Unit.


The successful candidate will perform the following tasks under the responsibility of their superior:

  • To collect and analyse information on GNSS (Global Satellite Navigation Systems) events (RFI, spoofing, iono) coming from States, GNSS service providers, on-board systems (e.g. ADS-B data), pilot reports (EVAIR) etc.;
  • To contribute to GNSS security studies by identifying and assessing threats (e.g. likelihood and severity of intentional jamming/spoofing) and define potential mitigation;
  • To disseminate the relevant findings and propose mitigation to support different operational stakeholders;
  • To collect and analyse GNSS data from core constellations and augmentations to assess the performance of different GNSS services (availability, continuity, integrity, service area), determine operational impact and interface with relevant stakeholders;
  • To support studies relating to Alternative Positioning, Navigation and Timing (A-PNT);
