The Issue of the Year WHAT IS IT S poofing AL SIMON MARKETING MANAGER NAVIGATION PRODUCTS ROCKWELL COLLINS The threat of spoofing as compared to jamming is perhaps a little more serious now in terms of what our customers are asking us to do With M code right around the corner this is the one near term thing they can do for the warfighter protect GPS CHRISTIAN RAMSEY UAS PROGRAM MANAGER HARRIS CRITICAL NETWORKS U AVs As the growth of small unmanned autonomous systems UAS operations increase in the National Airspace System it will be interesting to track how PNT standards and certifications evolve in order to adapt to a more versatile UAV aircraft certification system Likely a tiered system will be required to map PNT requirements for lower risk lower accuracy and lower cost applications to higher risk systems or those which require higher precision due to their mission profiles Constellation health Other Unintentional jamming A mong the options offered economic factors jamming and spoofing GNSS modernization and funding and open architecture integration across PNT technologies none raised significant alarm from survey takers A plurality in each case from 38 to 47 percent expressed themselves somewhat concerned about all of these factors with the economy and cross PNT integration getting the most attention 2016 STATE OF THE GNSS INDUSTRY 743 887 683 994 745 807 Intentional Jamming 1739 New signal capabilities interoperability MICHAEL JONES SENIOR CONSULTANT CAPABLITY LEAD ARRAY PROCESSING ROBUST PNT ROKE 3416 Unmanned autonomous vehicles UAVs SEPTEMBER 2016 WWW GPSWORLD COM GPS WORLD 45 Concerns A djacent channel interference has long been a concern in other domains such as electronic warfare and communications but GNSS in general has yet to experience the problem I foresee issues for some low cost receivers where frontend filtering is not sufficient but greater concerns for the high precision market There is a danger that the effects of adjacent L band transmissions will not come to light if the wrong tests are conducted or the wrong conclusions are drawn However this may later open up a whole new market for anti jam antennas It is time to get serious and construct a layered PNT architecture to bolster GPS with regional and local autonomous PNT sources for resiliency and precision Jules McNeff Overlook Systems Technologies Inc Spoofing Re emergence of LightSquared Ligado
