Improving Jamming and Spoofing Robustness with Multi-antenna GNSS Simulation
Wednesday 18th Nov 16:00 GMT
Anti-jamming and anti-spoofing capabilities are becoming essential features of mission-critical GNSS receivers and dependent systems. In the military domain, the need to protect mission-critical PNT systems led to the development of adaptive antennas, which are now also increasingly used in commercial applications such as surveying, mining and autonomous vehicles. Adaptive antenna systems need to be thoroughly tested, particularly if they are to be used in safety and liability-critical contexts.
In this webinar we will explore the challenges of reliably testing adaptive antennas and provide guidance on establishing test requirements.
We will then focus on the use of GNSS constellation simulators for the performance evaluation of advanced anti-jamming and anti-spoofing techniques of GNSS receivers using multiple antennas in an antenna array. This will be illustrated by the latest research done at the German Aerospace Centre (DLR), showing exemplary results for beamforming, direction of arrival estimation and spoofing detection in the corresponding signal scenarios.
