Assessing the Spoofing Threat: Development of a Portable GPS Civilian Spoofer

Abstract

A portable civilian GPS spoofer is implemented on a digital
\nsignal processor and used to characterize spoofing effects and develop defenses against civilian spoofing. This
\nwork is intended to equip GNSS users and receiver manufacturers
\nwith authentication methods that are effective
\nagainst unsophisticated spoofing attacks. The work also
\nserves to refine the civilian spoofing threat assessment
\nby demonstrating the challenges involved in mounting a
\nspoofing attack.
