In this webinar, Calian specialists explain how Global Navigation Satellite System (GNSS) jamming and spoofing affect positioning, navigation and timing (PNT) systems, along with methods for detecting and mitigating these threats.
The session examines narrowband and wideband jamming, their effects on GNSS antennas, radio frequency front ends and receivers, and the indicators that can help identify interference. It also covers mitigation using receiver-based techniques, low-elevation-angle nulling antennas and controlled reception pattern antennas (CRPAs).
The webinar explores different forms of spoofing and approaches for detecting and mitigating false GNSS signals, including direction-of-arrival analysis, signal authentication, receiver monitoring, measurement-level monitoring and comparison with non-GNSS sensors.
Calian also outlines how resilient GNSS antennas are designed and evaluated through simulations, anechoic chamber measurements and field testing. The session is relevant to radio frequency engineers, system integrators and defence professionals developing resilient PNT solutions.
