A fundamental issue facing GNSS users regarding the availability of service involves the presence of harmful interference — not only stray signals but also deliberate jamming. Military GNSS receivers need to be able to operate in unfriendly RF environments and, with increasing frequency, commercial and civil GNSS systems do, too.

Join Inside GNSS on Thursday, December 5, for a FREE web seminar on “The Role of GNSS Antennas in Mitigating Jamming & Interference.”

In 90 minutes of expert presentation, this webinar will provide an overview of signal processing for adaptive antenna systems and discuss key factors involved in integrating beamsteering antennas with GNSS receivers. It will describe the experience and lessons learned from live over-the-air jamming trials and address some practical considerations and the civil outlook going forward.

The webinar will also discuss the use of adaptive antennas for electronic protection. It will present guidelines for the physical antenna array design, including such factors as the effects of aperture size, aperture shape, number of elements, distribution of elements, and individual element characteristics on the adaptive array performance.
