GNSS signals are, by their nature, very weak and this makes them vulnerable to many types of jamming attacks. As the signal structure of most GNSS signals is well known and documented, false GNSS signals can be generated and transmitted by an attacker. These spoofing attacks typically cause a GNSS receiver to compute an incorrect position and timing information – making navigation practically useless.

Jamming and spoofing events occur very frequently and have become a major threat to the GNSS signal integrity over the last years. In 2020 alone, several thousand jamming and spoofing incidents have been reported and, in the meantime, the problem has also been recognized as an enormous economic risk.

One method of detecting and mitigating such threats is the use of adaptive antenna arrays. This webinar discusses how these systems work, what signal processing techniques are being used and how multi-antenna GNSS receivers can be tested against these types of threats with the help of signal generators from Rohde & Schwarz.

In this webinar, you will learn:

• What types of GNSS threats you have to consider when working with GNSS signals.
• How such threats can the detected and mitigated.
• How multi-antenna GNSS receivers can be used to detect and mitigate multipath as well as jamming and spoofing attacks.
• How signal generators from Rohde & Schwarz can be used to generate GNSS and jamming or spoofing signals to test multi-channel GNSS receivers.
