Presenter: Logan Scott
After a review of GPS signal structures and current satellite constellation status, this webinar provides a tutorial examination of how interference affects GPS signal reception. In particular, interrelations between jammer spectrum and GPS signal spectrum are explored. The role of code structure in assessing vulnerabilities is examined in detail for the civil C/A code. The Betz equation for computing cross coupling between an interference source and a spread spectrum signal is introduced in the context of GPS signals and the role of signal and jammer RF propagation is considered.
