ACKNOWLEDGMENTS

I would like to sincerely thank Dr. Frank van Graas for his guidance through this airport pseudolite research. Not only did Dr. van Graas teach me a great deal about GPS and precision approach but his level of expertise is far reaching in both technical and non-technical matters. It has been a pleasure working with him. I would also like to thank the members of my graduate committee: Dr. Roger Rollins, Dr. Roger Radcliff, Dr. Jeff Dill, and Dr. Michael Braasch, for their time and effort involved in the review, guidance, and approval throughout this dissertation process. I am grateful as well to Dr. Hollis Chen (Electromagnetic Departmental Group Chair) who made Electromagnetics seem so straightforward. In addition, I would like to thank program sponsors Ray Swider and Karl Kaser from the Federal Aviation Administration (FAA), at the Satellite Program for their support over the years. Special thanks also goes to Glenn Colby and Barbara Clark from the Naval Air Warfare Center, Aircraft Division for their continual support. Glenn Colby supported this research as it transitioned from a Navy-only project to an FAA supported project. For his outreaching support over the years I am very grateful. I would also like to thanks members of the Ohio University technical staff to include Dr. Richard McFarland (pilot), Dennis Atkeson (co-pilot), and Jay Clark (Aviation Maintenance) for the numerous flight hours logged in the Ohio University DC
