ACKNOWLEDGEMENTS
• Radio-Frequency Interference (RFI) signals are a current threat for
Global Positioning System (GPS) receivers due to their very low power
signals.
• GPS modulations and regulations to protect reserved frequency bands are
not enough to solve the problem of RFI and jamming.
• The number of jamming occurrences around the world is increasing
every year.
SOLUTION: FENIX – Front-End GNSS Interference eXcisor
Unintentional RFI
• Lower harmonics, inter-modulation products, bands overlapping, out-of-band.
• Other radio-frequency services may interfere with GPS signals.
Intentional RFI (Jamming)
• Commercial jammers are cheap (from 30 €), and available on the Internet.
• Blocks jamming signals and deliver the clean GPS signal to the receiver.
• Works for any GPS application and with any jamming signal
• Outperforms similar solutions already on the market.
• Smaller, lightweight, and versatile as compared to similar solutions in the market.
• Complementary to solutions based on antenna pattern modification or post-correlation.
• Each frequency band is treated with an independent processing chain.

CRITICAL GPS APPLICATIONS
• The number of critical applications that rely on Global Positioning System
(GPS) signals is high and increasing.
They can be divided in:
• Safety Critical Applications (SCA): a miss-behavior possess the potential
of directly or indirectly causing harm to humans, or to the environment.
• Liability Critical Applications (LCA): miss-performances can generate
legal or economic consequences.
