Contemplating a National Capability to Detect, Locate and Mitigate GNSS Interference

Milt Clary and Doug Taggart

Abstract:	Establishing a national capability to detect, locate and mitigate Global Navigation Satellite Signal (GNSS) interference is a necessary element of ensuring that these services are available and capable of meeting civil, commercial and scientific user expectations. The Global Positioning System (GPS), a predominate component of the world’s emerging GNSS, provides a civil, commercial and scientific public utility that is embedded in many elements of our nation’s underlying critical infrastructures. Since becoming operational in the mid-1990s the excellent track record of civil GPS performance, combined with its unconstrained use, unrestricted availability, and its non-proprietary, publicly available government standard makes it an extremely valuable utility serving the public good. Unfortunately, in today’s world of terrorist activities these positive attributes also make GNSS an attractive system for exploitation by those who have the intent of doing harm. This paper discusses the need to consider the benefits of establishing not only a national capability to monitor the performance of GNSS services from the perspective of detecting and locating sources of interference but additionally the need to disseminate information on such events and the implementation of training and exercises to identify, educate and better understand the effects and vulnerabilities to various types of interference. This resulting, proactive national capability will better ensure that the vision of protecting civil uses of GNSS is fulfilled.
