EUROCAE invites its members to participate in the Market Consultation organised by EUSPA: Market Consultation on the Development of Multi-Element Antenna for GNSS RFI Protection for Civil Applications.

Recently, there has been an escalation of jamming and spoofing events activities impacting GNSS services at worldwide level. GNSS is one of the main enablers in various market sectors, and particularly in aviation for performance-based navigation (PBN), which provides navigation guidance for all phases of flight, from enroute to precision approach. By providing accurate position and timing information, GNSS enables several systems critical to the safety of flight. To bring attention to the critical issue of GNSS interference, and to foster discussions on the management of GNSS vulnerabilities and potential mitigation measures against GNSS RFI, ICAO recently convened the ICAO EUR/MID Radio Navigation Symposium in Antalya, Turkey. One important outcome of the symposium is the identification of a list of recommendations regarding Stakeholders’ continued efforts towards ensuring safe, reliable, and resilient air navigation. Among the recommendations, Original Equipment Manufacturers (OEMs) should “improve their equipment and provide further guidance and information on the effects and mitigations of GNSS RFI”.

Multi-element antennas are identified as one of the most promising technologies to increase GNSS resiliency to RFI. Among multi-element-antenna technologies, Controlled-reception pattern antennas (CRPA) is a technique that exploits the spatial degrees of freedom of the antenna array to null or mitigate signals and reconstruct a single-antenna-like signal to feed it to any receiver. CRPA technology is already being used within the military industry to mitigate the adverse effects of GNSS RFI and could prove to be a game-changer also for civil applications.

The deadline for submission of responses is 4 November 2024, 23:59 CET.
