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

Directions 2013: Doing More with Less to Advance GNSS

December 1, 2012By

The history of GNSS shows each year has always been more successful than the year prior, and in 2013 we expect the trend to continue. In the United States, the role of GPS will continue to expand, and the applications for our technology will reach sectors we never imagined. As our international partner countries continue to launch GNSS satellites, and user equipment develops further, our community will increase its globalization, and international cooperation will reach new heights. read more

The System: Commercial GPS in Combat

June 1, 2012By

Signal Characteristics of Civil GPS Jammers
GPS jamming is a continuing threat. A detailed understanding of how the available jammers work is necessary to judge their effectiveness and limitations. A team of researchers from Cornell University and the University of Texas at Austin reports on their analyses of the signal properties of 18 commercially available GPS jammers. read more

Expert Advice: Test-Based Civil Receiver Certification

December 1, 2011By

Disaster-preparedness plans recognize the individual’s role in his or her own survival. When storms approach, have water, food, and basic survival gear on hand. It takes time for help to arrive. The civil GPS industry faces an oncoming storm of interference, and the receiver is the first line of defense. As we integrate GPS into all facets of our lives and infrastructure, we become more subject to disruptions, both unintentional and intentional. Newark International Airport now sees several jamming events per day. In Taiwan, one airport experiences an average of 117 events per day! read more
