WHITE PAPER
GNSS Jamming: How to test the risks to safety-critical and liability-critical systems
The reliance on GNSS signals for positioning, navigation, and timing (PNT) has made radio frequency (RF) interference from signal jamming a growing threat across various industries. Whether intentional or unintentional, jamming can significantly impact the performance of GNSS receivers, including those used for safety-critical and liability-critical operations. Therefore, developers and integrators of GNSS receivers must understand the risks presented by jamming and implement mitigation measures to protect the receivers and their users.

CASE STUDY
Delivering the next generation of GNSS anti-jam and anti-spoof technology with DLR
The use of Global Navigation Satellite Systems (GNSS) is expanding across various industries, but with it comes an increasing threat of GNSS jamming and spoofing. Deutsches Zentrum für Luft- und Raumfahrt (DLR), Germany's research center for aeronautics and space, recognized the need to develop anti-jam and anti-spoof technology to protect critical applications like commercial aviation, shipping, and autonomous vehicles. DLR developed GALANT, an advanced system that uses nulling and beamforming to counter interference.

WHITE PAPER
Understanding latency for hardware-in-the-loop testing
Modern vehicles, whether autonomous or assisted, heavily rely on precise positioning, navigation, and timing (PNT) information for safety, efficiency, and mission-critical tasks. GNSS technology has evolved to meet these demands, offering a variety of hardware and services options, including multi-constellation and multi-frequency receivers, terrestrial and space-based augmentation systems, and complex array antennas. However, the inclusion of additional PNT sensors working together with GNSS has become increasingly important for seamless and reliable performance.
