As the world becomes “cluttered” with ever new cellular and terrestrial signals, it becomes ever increasingly difficult to ensure GNSS signal reception and processing. Join this webinar to learn about some of these new signals, how they can interrupt or deny GNSS reception, and what can be done to mitigate the problem.
In today’s congested RF environment, many cellular and other communication signals interfere with the GNSS spectrum. Cellular signals and their harmonics can cause a non-tightly filtered antenna to saturate. When this happens, the GNSS receiver will not receive a clean GNSS signal and navigation may be disrupted. Tallysman has developed robust filtering techniques to enable antennas to perform optimally even in close proximity to interfering signals.
