Enhanced GNSS Jamming & Spoofing Resilience

The risks associated with global navigation satellite systems (GNSS) interference represent significant threats to positioning, navigation and timing (PNT). Disruptions to GNSS can result in severe consequences to critical operations in various industries, including aviation, marine and defense. 

Threats to GNSS signals fall into two broad categories: jamming and spoofing. Jamming results in a loss of PNT information, because the GNSS signal is overpowered by the jamming signal. Spoofing, on the other hand, tricks the receiver into reporting incorrect PNT information.

As reliance on GNSS continues to grow, enhancing the resilience of GNSS technology against intentional interference is vital to maintaining the integrity and reliability of global PNT services.
