In those old days\, we would use pape r maps\, ask people for directions\, and use physical landmarks to navigat e to where we needed to go. In ancient times\, people used celestial bodie s such as the sun\, moon\, and stars for navigation. Today\, whether we re alize it or not\, we all rely on GPS for many aspects of society. Every ce ll phone has GPS\, almost all unmanned systems have GPS. GPS is used by ca rs\, ships\, and planes for navigation. We use it to get to where we need to go. Unmanned systems use it to perform their jobs. Commerce and shippin g industries rely on it for global material and product distribution. Comm erce relies on it for location-based services (all those apps on your phon e you use to buy things). GPS is a cornerstone of America's economy.\n\nHo wever\, there are many environments in which GPS does not perform well. Fu rthermore\, GPS is vulnerable to many types of hostile attacks. It is poss ible to jam GPS signals. It is possible to spoof (i.e.\, impersonate) GPS signals. The GPS satellite constellation itself is vulnerable to attack. G lobal geopolitical tensions and the military capabilities of many other na tions means that one day\, it is possible that we all wake up and GPS isn' t there\, or it isn't usable. So what happens then?\n\nThis talk first pre sents an overview of the GPS system and how GPS works. The talk then goes on to discuss some of the performance challenges faced by GPS (e.g.\, perf ormance in dense urban environments). We then we discuss some of the ongoi ng research being conducted to defeat the threats faced by GPS. We will le arn how researchers are working to both detect and defeat hostile attacks. Finally\, the tutorial then goes on to discuss the various methods resear chers are attempting to provide reliable positioning\, navigation\, and ti ming (PNT) in a completely GPS-denied environment using non-GPS methods.\n \nDinner will consist of:\n\n-\nCarved Beef Brisket\n- Garden Salad\n- Fin gerling Potatoes\n- Seasonal Vegetable Medley\n- Assorted Dinner Rolls\n- Brownies\n\nParking for the event is free and is in the parking lot south of the library.
