WEBINAR

Testing Adaptive Antenna Arrays for GNSS Receivers

By their nature, GNSS signals are weak and vulnerable to interference as false ones can easily be generated and transmitted – leading to navigation that is practically useless.

One method to detect and mitigate such threats is the use of adaptive antenna arrays. The webinar explains how these systems work, what signal processing techniques are being used and how multi-antenna GNSS receivers can be tested against these threats using signal generators from R&S.

Registering gives you access to this webinar even after it airs!
