28 days worth of ship-traffic data for the Strait of Dover.

An overview of the work of the General Lighthouse Authorities of the United Kingdom and Ireland on the implementation of Enhanced Loran Initial Operational Capability (IOC) in the waters around Great Britain. eLoran is the latest in the longstanding and proven series of low-frequency, LOng-RAnge Navigation systems. It evolved from Loran-C in response to the 2001 Volpe Report on GPS vulnerability. It vastly improves upon previous Loran systems with updated equipment, signals, and operating procedures. read more

UK Switches on eLoran for Backup in the English Channel

January 9, 2013By

Directions 2013: The Future of GNSS Security

December 1, 2012By

The GNSS interference session this year at the ION-GNSS conference in Nashville was one of the most crowded, confirming the need of all sectors of the community to understand the threats in GNSS and how they can be mitigated. In that context I received one of the most challenging questions of my career: “Can we predict the future of GNSS security?” What is the status of civil and commercial GNSS security today? Which are the threats and risks and how they are mitigated? Where are we going and what shall we expect from the future? read more

Tip Line Encourages Public Participation in the Fight Against GPS Jammers

November 2, 2012By

Washington, D.C. — The Federal Communications Commission’s Enforcement Bureau today launched a dedicated jammer tip line – 1-855-55-NOJAM (or 1-855-556-6526) – to make it easier for the public to report the use or sale of illegal GPS, cell phone or other signal jammers. It is against the law for consumers to use, import, advertise, sell or ship a GPS or... read more

By Daniel Shepard, Jahshan A. Bhatti, and Todd E. Humphreys  Unmanned aerial vehicle (uav) used in the spoofing tests; owned by the University of Texas.  A radio signal sent from a half-mile away deceived the GPS receiver of a UAV into thinking that it was rising straight up. In this way, the UAV’s dependence on civil GPS allowed the... read more

Detecting False Signals with Automatic Gain Control

FIGURE 6. Google Earth view of testing environment.

A component of most GPS receiver front-ends, the automatic gain control (AGC) can flag potential jamming and spoofing attacks. The detection method is simple to implement and accessible to most GPS receivers. It may be used alone or as a complement other anti-spoofing architectures. This article presents results from a baseline AGC characterization, develos a simple spoofing detection method, and demonstrate the results of that method on receiver data gathered in the presence of a live spoofing attack. read more
