Excerpt
Excerpt: GLOBAL POSITIONING SYSTEM (GPS) USE FOR ALL-WEATHER LANDINGS. The aviation industry is investigating the use of differential GPS concepts for precision landings in bad weather to improve the safety and reliability of air travel. The GPS is a constellation of 24 satellites used to determine aircraft position anywhere on or near the Earth. When a ground based GPS receiver is used to provide a ?differential? correction signal, an aircraft?s position can be determined within a foot or two. Boeing partnered with NASA to examine GPS Landing System concepts and evaluate their accuracy, integrity, and continuity of function in automatic landings of airplanes. The team tested several prototype GPS Landing System concepts using NASA 557 during 226 automatic approaches and landings. The data obtained is being used to validate GPS Landing System simulations and to define system certification requirements...
