Chefs from U.S. Air Force 746th Test Squadron GPS Test Center of Expertise cook up a winning formula for a booth display, a RECIPE of Resources, Experience, Capability, Innovation, Process, and Efficiency. Visitors were asked to solve an intriguing word puzzle to receive a delicious prize. GPS World’s booth offered a Wii bowling challenge for fun and exciting prizes. A young bowler from Bavaria (above) and ION President Mikel Miller’s family (below) enjoy an evening at the GPS World bowling alley. A visitor to NovAtel’s booth tries his piloting hand in a 3-D attitude solution with NovAtel’s GPS/INS SPAN-CPT product. Used as a controller in the flight simulator, it mimics an actual SPAN application as profiled in the September GPS World. Miniature autonomous vehicles navigating the mean streets of a LEGO town take center stage on the show floor to highlight the Institute of Navigation’s first Mini-Urban Challenge and upcoming second challenge, now seeking sponsors. Northrop Grumman personnel Jill Rigler, Ed Chou, George Vannick, and Velvet Hoover explain the company’s programs to booth visitors on the show floor. Northrop Grumman was a Gold Sponsor of GPS World’s Leadership Dinner. Larry Skorski of the U.S. Coast Guard took first place in GPS World’s Wii Bowling Challenge (score, 225). Editor Alan Cameron presents him with a copy of Brad Parkinson and James Spilker’s book, The Global Positioning System, signed by the first author.
