Case Study: DLR achieves advanced GNSS anti-jam and anti-spoof testing with Spirent Communications

Delivering the next generation of GNSS anti-jam and anti-spoof technology with DLR

Deutsches Zentrum für Luft- und Raumfahrt (DLR), Germany's national research center for aeronautics and space, required a powerful and flexible simulation system to develop and test its advanced GALANT anti-jam, anti-spoof GNSS array receiver. The growing threats of jamming and spoofing to safety-critical civilian applications like aviation and shipping necessitated a testing environment capable of generating complex, multi-constellation scenarios with precise phase alignment for up to eight antenna elements.

Spirent Communications delivered a customized GSS9000 multi-element GNSS simulation system. This solution enabled DLR to prove that its GALANT system's beamforming and null-steering technology significantly reduced the impact of jamming, prevented a drop in available satellites, and even increased satellite visibility. The tests provided scientific, repeatable results, and the flexible Spirent system ensures it can meet DLR's future development requirements.
