Austin, TX — Kyle Wesson, Daniel Shepard, and Todd Humphreys authored the cover story of GPS World on anti-spoofing techniques for civil GPS in the January 2012 edition.
The introduction reads, “Disruption created by intentional generation of fake GPS signals could have serious economic consequences. This article discusses how typical civil GPS receivers respond to an advanced civil GPS spoofing attack, and four techniques to counter such attacks: spread-spectrum security codes, navigation message authentication, dual-receiver correlation of military signals, and vestigial signal defense. Unfortunately, any kind of anti-spoofing, however necessary, is a tough sell.”
