Septentrio details how its GNSS receivers were validated for use in safety-critical air traffic management systems through live jamming and spoofing testing conducted at JammerTest in Andøya, Norway.
Saab selected a Septentrio GNSS receiver protected by AIM+ Advanced Interference Mitigation technology to strengthen resilience against GNSS jamming and spoofing in its air traffic management systems.
Saab air traffic management systems support flight operations and incorporate a Cooperative Surveillance System that combines multiple sensors to provide multilateration and ADS-B surveillance. These sensors rely on GNSS timestamps to ensure accurate synchronization. ADS-B, or Automatic Dependent Surveillance–Broadcast, is used in air traffic management to enhance aircraft surveillance in the air and on the airport surface.
Avinor, the Norwegian air navigation service provider and a Saab customer, invited Saab to participate in JammerTest to validate system performance. Saab attended the event with its sensor system using Septentrio’s AsteRx SB3 GNSS receiver. Data was collected across a range of GNSS jamming and spoofing scenarios to evaluate the performance of Saab’s Cooperative Surveillance System multilateration and ADS-B sensors.
Robert Brown, Director of Portfolio, Sales and Strategy at Saab Air Traffic Management, said, “Although they may not realize it, each year hundreds of millions of passengers rely upon Saab’s air traffic management systems to get where they are going safely. Most of these systems in turn rely upon GPS/GNSS for positioning and time synchronization. With so much at stake, Saab is proud to offer industry leading anti-spoofing and anti-jamming capabilities using Septentrio equipment. Saab and Septentrio’s recent collaboration at JammerTest showcased just how effective we can be together.”
Test results showed that the combined Saab and Septentrio solution withstood multiple forms of GNSS interference during live jamming and spoofing conditions.
Septentrio GNSS receivers used in Saab air traffic management systems provide multi-frequency GNSS access to available satellite constellations and signals, nanosecond-level time synchronization, AIM+ anti-jamming technology, and AIM+ anti-spoofing functionality, including Galileo OSNMA.
