GPS Anti-Jamming and Anti-Spoofing Solution (GNSS Resilience)
Active, retrofittable protection against GNSS jamming and spoofing for civil aircraft — beyond detection-only OEM offerings.
Retrofit modification unveiled by Fokker Services Group at Dubai Airshow 2025 that provides active, real-time protection against GPS/GNSS jamming and spoofing, rather than the detection-only capability of current OEM offerings. Built around Controlled Reception Pattern Antenna (CRPA) multi-element array technology, it integrates with existing GNSS and Flight Management System installations to preserve RNP, LPV and GNSS-based navigation continuity, and supports predictive navigation integrity monitoring.
Interference protection matters for the many downstream systems that rely on clean GNSS: FMS, TAWS/EGPWS, TCAS, SATCOM, ATC surveillance and GPS/IRS hybrid navigation. Delivered as a complete modification kit with all parts and engineering bulletins, integrating with existing avionics and flight-deck procedures with no additional pilot training.
Offered as an EASA Part 21J-certified modification, initially for the Boeing 737NG and 747, with STC development available for additional Airbus, Boeing, Embraer and other types; Fokker states applicability across regional, narrowbody and widebody platforms in commercial, VIP, cargo and defence markets. Entry into service was announced for January 2026 with undisclosed launch operators.
