IN FOCUS Trailblazer A Delta IV rocket carrying the fifth Boeing GPS IIF satellite leaves a bright trail across the night sky after launch from Cape Canaveral Air Force Station, Fla., Feb. 20. The latest Boeing-built Global Positioning System satellites are providing greater navigational accuracy through improvements in atomic clock technology, a more resilient signal for commercial aviation and a longer design life of 12 years. The sixth GPS IIF is at the Florida launch site undergoing preparations for launch in the second quarter of the year. The remaining six are being stored and maintained at the Boeing Satellite Development Center in El Segundo, Calif., to be launched as needed by the Air Force.
